RESUMO

PURPOSE: To assess the repeatability, intra and interrater reproducibility of the DIPA-S eHealth© system for capturing and measuring clinical variables of scoliosis, including frontal trunk imbalance (FTI), sagittal trunk imbalance (STI), and angle of trunk rotation (ATR). METHODS: Patients were photographed using the DIPA-S eHealth Capture© mobile application by family members, physiotherapists, or surgeons. Three photos were taken in each position: standing in the frontal and sagittal planes and in the axial plane in forward bending position of the trunk. The photos were analyzed by three independent evaluators using the DIPA-S eHealth Analysis© software. For repeatability, each photo was analyzed twice consecutively by the three evaluators. For intrarater reproducibility, only one evaluator reanalyzed the first photo from each plane with a 5-day interval. For interrater reproducibility, the three evaluators analyzed the first photo from each plane. The intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable change (MDC) were used (p < 0.05). RESULTS: The sample comprised 262 images (n = 30). Repeatability was excellent for all three evaluators in all three planes (ICC 0.94 to 1.00). Intrarater reproducibility was excellent in all three planes (ICC 0.88 to 0.99). Interrater analysis was excellent for the frontal and axial planes (ICC 0.98 and 0.93), respectively. However, it was weak in the sagittal plane ICC 0.32. The SEM ranged from 0.02 to 17.6 and MDC from 0.03 to 34.6. CONCLUSION: The DIPA-S eHealth© Capture and Analysis system demonstrates reproducibility for use in the clinical assessment of scoliosis through teleconsultations.

RESUMO

PURPOSE: To develop a questionnaire for adolescent idiopathic scoliosis (AIS) patients undergoing physiotherapeutic scoliosis-specific exercises (PSSE) and to evaluate its content validity, structural validity, and reliability. METHODOLOGY: Seven PSSE treatment experts checked the content validity of the Patient's Perception of Scoliosis-Specific Physiotherapy Questionnaire (Physio-IS). For each Physio-IS item, the content validity indexes must be ≥ 90%. Regarding structural validity and reliability 52 adolescents (ages 10-17) with AIS completed the questionnaire. Structural validity was assessed through exploratory factor analysis. Reliability was verified through internal consistency. RESULTS: Physio-IS content was validated in three evaluation rounds, obtaining 100% expert agreement. About structural validity we identified four domains (cumulative explained variance = 68.2%): (1) specific knowledge (seven questions on understanding their scoliosis condition); (2) social repercussion (five questions about social relationship implications); (3) pain (two questions about scoliosis-associated pain); and (4) associated concern (apprehension/expectations regarding the future). The Physio-IS demonstrated very good internal consistency (Cronbach's alpha = 0.76-0.92). CONCLUSION: The Physio-IS is a valid and reliable tool for assessing AIS patients undergoing PSSE and helping physiotherapists identify aspects requiring more attention, thus facilitating intervention strategies, as knowing the patient's perception of their condition or treatment is fundamental to AIS treatment success.

Physio-IS is an innovative tool in the treatment of Adolescent idiopathic scoliosis (AIS).Physio-IS is a valid and reliable tool for the assessment of adolescents with AIS undergoing phyisiotherapeutic scoliosis-specific exercises (PSSE).The specific questionnaire can contribute to physiotherapeutic treatment decisions, allowing the physical therapist to see the patient as a whole.

RESUMO

With the enforcement of social distancing due to the pandemic, a need to conduct postural assessments through remote care arose. So, this study aimed to assess the intra- and inter-rater reproducibility of the Remote Static Posture Assessment (ARPE) protocol's Postural Checklist. The study involved 51 participants, with the postural assessment conducted by two researchers. For intra-rater reproducibility assessment, one rater administered the ARPE protocol twice, with an interval of 7-days between assessments (test-retest). A second independent rater assessed inter-rater reproducibility. Kappa statistics (k) and percentage agreement (%C) were used, with a significance level of 0.05. The intra-rater reproducibility analysis indicated high reliability, k values varied from 0.921 to 1.0, with %C ranging from 94% to 100% for all items on the ARPE protocol's Postural Checklist. Inter-rater reproducibility indicates reliability ranging from slight to good, k values exceeded 0.4 for the entire checklist, except for four items: waists in the frontal photograph (k = 0.353), scapulae in the rear photograph (k = 0.310), popliteal line of the knees in the rear photograph (k = 0.270), and foot posture in the rear photograph (k = 0.271). Nonetheless, %C surpassed 50% for all but the scapulae item (%C = 47%). The ARPE protocol's Postural Checklist is reproducible and can be administered by the same or different raters for static posture assessment. However, when used by distinct raters, the items waists (front of the frontal plane), scapulae, popliteal line of the knees, and feet (rear of the frontal plane) should not be considered.

RESUMO

Abstract Introduction Individuals with autistic spectrum disorder (ASD) have motor impairments that precede communi-cation and socialization disorders. Evaluative instruments compatible with the real possibilities and specificities of patients with ASD, and who quantitatively and qualitatively translate the data in which is wished to intervene with therapeutic actions, are important both in the scope of research and in the clinical evaluation of physiotherapists. Objective To test the interobserver and intraobserver reproducibility of the instrument "Gross Motor Assessment of Children and Adolescents with Autism Spectrum Disorder" (GMA-AUT checklist). Methods The sample consisted of 34 individuals with ASD, aged between 6 and 18 years. The interobserver reproducibility was performed in a blinded manner by two physiotherapists experts in the ASD area of treatment. Intraobserver reproducibility was performed by one of the evaluators on two different days, with a gap of seven days and without access to data from the first evaluation. To verify the reproducibility, percentage of agreement and kappa statistics (k) were used, with the weighted kappa and, for the instrument scores, the intraclass correlation coefficient (ICC). Results The GMA-AUT checklist showed excellent intraobserver agreement, with k ≥ 0.75 and ICC > 0.75. Interobserver reproducibility ranged from good to sufficient agreement with k between 0.40 and 0.75 and ICC > 0.75 for the most part. Conclusion The GMA-AUT checklist had excellent intraobserver reproducibility and, therefore, can be reliably used for assessments of individuals aged between 6 and 18 years with ASD.

RESUMO

INTRODUCTION: Multiple Sclerosis, known main cause of non-traumatic neurological disability in adults, leads to changes in muscle strength, especially in the lower limbs. Assessing muscle strength in these patients is thus essential and can be achieved by the Five Times Sit to Stand Test (FTSST), commonly performed in person. Due to the COVID-19 pandemic and social distancing measured adopted, Brazilian physiotherapists turned to remote monitoring and assessment, supported by Resolution n° 516/2020, which required proving the reliability of tests. Given this scenario, this study sought to evaluate the intra- and inter-rater reliability of the Five Times Sit to Stand Test performed remotely and synchronously by multiple sclerosis patients. METHODS: A sample of 33 individuals with relapsing-remitting Multiple Sclerosis (18 women and 15 men, mean age 43.7 ± 13.4 years) were remotely and synchronously by video call. Inter-rater reliability was evaluated by analyzing FTSST execution time, in seconds, timed by two different raters on the same video call. In turn, intra-rater reliability was assessed by analyzing the execution time recorded in two different video calls made by the same rater, within a 24-28-h interval. Descriptive and inferential data analysis were performed using SPSS 20.0 software. Means and standard deviation were calculated for descriptive statistic. Intraclass correlation coefficient (ICC), with a 0.05 significance level, standard error of measurement (SEM) and minimal detectable change (MDC) were calculated for inferential analysis. RESULTS: Data analysis showed excellent ICC values and low SEM and MDC values regarding inter-rater reliability (ICC: 0.993 (0.986-0.996); p-value: <0.001; SEM: 0.6 s; MDC: 1.6 s) and intra-rater reliability (ICC: 0.962 (0.925-0.981); p-value: <0.001; SEM: 1.4 s; MDC: 3.8 s). CONCLUSION: Based on these values, FTSST performed remotely and synchronously by relapsing-remitting Multiple Sclerosis patients is reliable and can be used both by different raters, for assessment, or by the same rater, in pre- and post-test situations.

RESUMO

Objective: The purpose of this literature review was to identify knee alignment assessment methods using radiography in the sagittal and frontal planes and to identify normality values for classifying knee alignment using these methods. Methods: A systematic review with a meta-analysis was conducted. The eligibility criterion was studies that performed radiographic examinations to assess the knee alignment of adults without a history of hip or knee prosthesis surgery. The methodological qualities of the included studies were assessed using the QUADAS-2 tool. A meta-analysis was performed to measure the normality values of knee alignment in the frontal plane. Results: The hip-knee-ankle (HKA) angle was the measure most frequently used to assess knee alignment. Only a meta-analysis of HKA normality values was possible. Thereby, we found normality values of the HKA angle for the overall population, men, and women. The normality values of knee alignment for healthy adults that were found in this study were as follows: overall sample (male and female patients) HKA angle = -0.2° (-2.8° to 2.41°), male patient HKA angle = 0.77° (-2.91° to 7.94°), and female patient HKA angle = -0.67° (-5.32° to 3.98°). Conclusion: This review identified the most common methods and expected values for knee alignment assessment methods using radiography in the sagittal and frontal planes. We suggest HKA angles ranging from -3° to 3° as the cutoff for classifying knee alignment in the frontal plane, in accordance with the normality limits found in the meta-analysis.

RESUMO

Background: When performed in unfavorable conditions, work can lead to the development of musculoskeletal disorders and decrease in work ability. Objectives: To identify the differences between three groups of workers (professors, technicians and outsourced workers) as for the sociodemographic profile, work ability, prevalence of musculoskeletal disorders, activity restrictions, and the correlation between the presence of musculoskeletal disorders and activity restrictions with each domain of the Work Ability Index. Methods: The sample consisted of 67 university workers assessed by a Sociodemographic Data Questionnaire, the Nordic Musculoskeletal Symptoms Questionnaire and the Work Ability Index. Descriptive statistics and Kendall's Tau correlation coefficient were used. Results: Professors presented more favorable sociodemographic and lifestyle aspects and higher work ability, while outsourced workers had less favorable sociodemographic and lifestyle aspects and lower work ability. The correlation between activity restrictions and work ability was found in only one domain of Work Ability Index among professors. Among outsourced workers were found correlations on presence of musculoskeletal disorders and activity restrictions with six domains of Work Ability Index. Technicians did not show significant correlation. Conclusions: Outsourced workers presented worse work ability and less favorable sociodemographic and lifestyle aspects among the workers in the study, requiring the maintenance and improvement of work ability in this population.

Introdução: O trabalho, quando realizado em condições desfavoráveis, pode levar ao desenvolvimento de distúrbios musculoesqueléticos e à diminuição da capacidade para o trabalho. Objetivos: Identificar diferenças entre três grupos de trabalhadores (professores, técnicos e terceirizados) em relação a perfil sociodemográfico, capacidade para o trabalho, presença de distúrbios musculoesqueléticos e restrição para atividades e correlacionar a presença de distúrbios musculoesqueléticos e a restrição para atividades com cada domínio do índice de Capacidade para o Trabalho. Métodos: A amostra foi composta por 67 trabalhadores de uma universidade, os quais preencheram um questionário de dados sociodemográficos, o Questionário Nórdico de Sintomas Osteomusculares e o índice de Capacidade para o Trabalho. Foram utilizados estatística descritiva e o teste tau de Kendall para identificar possíveis correlações. Resultados: Os professores apresentaram aspectos sociodemográficos e de estilo de vida mais favoráveis e maior capacidade para o trabalho, enquanto os terceirizados apresentaram aspectos sociodemográficos e de estilo de vida menos favoráveis, além de menor capacidade para o trabalho. Foi encontrada correlação entre restrição para atividades em apenas um dos domínios do Índice de Capacidade para o Trabalho entre professores. Entre os terceirizados, foram encontradas correlações entre a presença de distúrbios musculoesqueléticos e a restrição para atividades em seis domínios do índice de Capacidade para o Trabalho. Os técnicos administrativos não apresentaram correlações significativas. Conclusões: Os trabalhadores terceirizados apresentaram pior capacidade para trabalho e aspectos sociodemográficos e de estilo de vida menos favoráveis entre os trabalhadores do estudo, sendo necessárias a manutenção e a melhora da capacidade para o trabalho desta população.

RESUMO

ABSTRACT Postural therapies use active treatment methods, such as self-correction, to control body segments. The evidence for this practice is established from the comparison of the self-perception of body posture before, during, and after postural education. A scoping review of tools to assess self-perception of body posture, besides encouraging research, may guide professionals while developing treatments. This scoping review aims to identify the existing tools that assess self-perception of body posture, describing their type, measurement properties (validity and reliability), and postural outcomes. The protocol of this review was registered in the Open Science Framework (OSF), DOI: 10.17605/OSF.IO/JGH8U. Studies developing and/or evaluating measurement properties and other study designs using self-perception of static body posture as an assessment method were included. In total, 359 studies were found, of which six were analyzed in this study. They presented two types of tool and their measurement properties were related to validity (n=6) and reliability (n=5). Five studies performed the joint analysis of validity and reliability (83%). Spine position, leg and foot posture, trunk and rib deformity, and postural awareness in general were the assessed postural outcomes. Of the six tools that assess self-perception of body posture, only the SSFS scale can be used in any population. To date, no study found a tool that assesses self-perception of body posture and considers all body segments.

RESUMEN Las terapias posturales utilizan métodos de tratamiento activo, como la autocorrección, para alinear los segmentos del cuerpo. La autopercepción de la postura corporal comparada antes, durante y después del trabajo en educación postural permitirá establecer la evidencia de esta práctica. Una revisión de alcance de los instrumentos que evalúan la autopercepción de la postura corporal, además de incentivar los estudios, puede orientar a los profesionales en las prácticas terapéuticas. El objetivo de esta revisión de alcance es identificar los instrumentos existentes que evalúan la autopercepción de la postura corporal, con la descripción del tipo de instrumento, sus propiedades de medición (validez y confiabilidad) y los resultados posturales. El protocolo para esta revisión está registrado en Open Science Framework (OSF), doi: 10.17605/OSF. IO/JGH8U. Se incluyeron estudios de desarrollo y/o evaluación de propiedades de medición u otros tipos de estudio que utilizaron la autopercepción corporal estática como método de evaluación. Se identificaron un total de 359 estudios, de los cuales seis se incluyeron en esta investigación. Estos presentaron dos tipos de instrumentos. Las propiedades de medición se relacionaron con la validez (n=6) y la confiabilidad (n=5). El análisis conjunto de validez y confiabilidad fue realizado por cinco estudios (83%). Los resultados posturales evaluados fueron: posición de la columna; postura de piernas y pies; deformidad del tronco y las costillas; y conciencia de la postura en general. Se identificaron seis instrumentos que evalúan la autopercepción de la postura corporal, pero solamente la escala SSFS puede ser utilizada en cualquier población. Hasta el momento, no se identificó ningún instrumento que evalúe la autopercepción de la postura corporal y que considere todos los segmentos corporales en el análisis.

RESUMO As terapias posturais utilizam métodos de tratamento ativo, como a autocorreção, para o alinhamento dos seguimentos corporais. É a partir da comparação da autopercepção da postura corporal antes, durante e após o trabalho em educação postural que as evidências dessa prática serão estabelecidas. Uma revisão de escopo sobre os instrumentos de avaliação da autopercepção da postura corporal, além de fomentar pesquisas, poderá guiar os profissionais nas condutas terapêuticas.

RESUMO

Abstract Introduction Remote postural assessment, necessary during the pandemic, required strategies to replace its in-person counterpart. Objective Analyze the content validity of a protocol for Remote Static Posture Assessment (ARPE) that includes three items, postural checklist, rater's manual and ratee's manual. Methods Six experts in postural assessment were invited to validate the content of the three items of the ARPE protocol and 10 laypersons evaluated the ratee's Manual. The validity questionnaire encompassed the protocol in general and each individual item, containing an area for suggestions from experts and laypersons. The responses of these raters were used to calculate the Content Validity Indexes (CVI). Results Two rounds of evaluations were carried out with the experts and one with the laypersons. In the first round with the experts, the CVI ranged from 98.6 to 83%. Three aspects (description of head positioning, description of scapula and waist positioning in the frontal plane) required adjustments. In the first round with the laypersons and second round with the experts, the CVI was 100%. Conclusion The 100% agreement between experts and laypersons regarding the content of the ARPE protocol confirms its content validity.

Conclusão A concordância de 100% entre os especialistas e leigos sobre o conteúdo do protocolo ARPE confirma sua validade de conteúdo.

RESUMO

RESUMO A articulação do ombro possui a maior amplitude de movimento e está mais suscetível a disfunções. Avaliações dinâmicas e quantitativas dessa região fornecem melhores informações para a clínica, mas a escolha do método a ser utilizado depende de suas propriedades de medição. O objetivo deste estudo foi identificar os métodos existentes de avaliação dinâmica quantitativa do complexo ombro e escápula em um contexto clínico para a população em geral, identificando as propriedades de medição e os desfechos avaliados para cada método. A revisão de escopo incluiu estudos in vivo, com amostras sem uma condição clínica específica e envolvendo métodos aplicáveis em um contexto clínico. Foram identificados: desfecho avaliado, método de medição e suas propriedades de medição. Foram selecionados 29 estudos que investigaram 12 métodos de medição, sendo avaliadas sua validade e confiabilidade para 17 desfechos diferentes. A posição do ombro e da escápula e os desfechos derivados foram abordados pelo maior número de estudos (n=21), sendo seus principais métodos de avaliação as unidades de medição inercial (n=5) e unidades de medição magnética inercial (n=6). Os desfechos que apresentaram métodos válidos e confiáveis foram: amplitude articular de ombro; amplitude de movimento da escápula e do ombro; atividade muscular; centro articular do ombro; comprimento do úmero; curva torque-tempo; desempenho funcional; discinesia escapular; força de rotadores externos do ombro; funcionalidade e amplitude articular; movimento escapular inicial; posição da escápula e do ombro; e velocidade angular do ombro.

RESUMEN La articulación del hombro tiene la mayor amplitud de movimiento y es más susceptible a disfunciones. Las evaluaciones dinámicas y cuantitativas de esta región proporcionan mejores informaciones para la clínica, pero la elección del método a utilizar depende de sus propiedades de medición. El objetivo de este estudio fue identificar los métodos existentes de evaluación dinámica cuantitativa del complejo del hombro y escápula en un contexto clínico para la población general, identificando las propiedades de medición y los resultados evaluados para cada método. La revisión de alcance incluyó estudios in vivo, con muestras sin una condición clínica específica y con métodos aplicables en un contexto clínico. Se identificaron el resultado evaluado, el método de medición y sus propiedades de medición.

La posición del hombro y de la escápula, y los resultados derivados fueron abordados por el mayor número de estudios (n=21), y sus principales métodos de evaluación fueron las unidades de medición inercial (n=5) y las unidades de medición magnética inercial (n=6). Los resultados que presentaron métodos válidos y confiables fueron: amplitud articular del hombro; amplitud de movimiento de la escápula y del hombro; actividad muscular; centro articular del hombro; longitud del húmero; curva torque-tiempo; desempeño funcional; discinesia escapular; fuerza de los rotadores externos del hombro; funcionalidad y amplitud articular; movimiento escapular inicial; posición de la escápula y del hombro; y velocidad angular del hombro.

ABSTRACT The shoulder joint has the greatest range of motion and is the most susceptible to dysfunction. Dynamic and quantitative evaluations of this region provide better information for the clinic but the choice of the method depends on its measurement properties. This study aimed to identify the existing methods of quantitative dynamic evaluation of the shoulder and scapula complex, in a clinical context for the general population, identifying the measurement properties and outcomes of each method. The scoping review included in vivo studies, with samples without a specific clinical condition and involving applicable methods in a clinical context. We identified evaluated outcome, measurement method, and its measurement properties. We selected 29 studies that investigated 12 measurement methods, and evaluated their validity and reliability for 17 different outcomes. Most studies (n=21) addressed the position of the shoulder and the scapula and the derivative outcomes, using mainly the units of inertial measurement (n=5) and inertial magnetic measurement (n=6) as evaluation methods. The outcomes with valid and reliable methods were: shoulder joint range; scapula and shoulder motion range; muscle activity; shoulder joint center; humerus length; torque-time curve; functional performance; scapular dyskinesia; external shoulder rotators force; shoulder joint functionality and range; initial scapular movement; scapula and shoulder position; and shoulder angular velocity.

RESUMO

Risk factors associated with back pain vary in different countries. Given the lack of studies in Latin America, our study aimed to assess back pain and its associated factors for six years in Southern Brazilian school children. All children attending the fifth grade of Teutônia, Brazil, were invited to participate in the study. Only schoolchildren who did not report back pain were included in the first assessment. The schoolchildren completed the Back Pain and Body Posture Evaluation Instrument (BackPEI) during three assessments (2011, 2014, and 2017). BackPEI assesses the presence of back pain and possible associated risk factors (postural, behavioral, and sociodemographic). Generalized estimated equations (GEE) were used to perform a Poisson regression model with robust variance for longitudinal analysis. After six years of follow-up, 75 schoolchildren completed all the assessments. The risk factors associated with back pain were spending more than six hours daily watching television, lifting objects from the ground adopting an inadequate posture, using another backpack type different from those with two straps, and carrying a backpack in an asymmetric way. These results are important in guiding the planning of public policies to minimize this public health problem.

RESUMO

The Back Pain and Body Posture Evaluation Instrument (BackPEI) was created in 2013 to assess back pain and its risk factors in school children. However, it does not assess neck pain or the habits of mobile device usage, which are aspects that are often part of school children's lives. Therefore, we aimed to update the BackPEI questionnaire to include new questions assessing aspects related to neck pain and the use of mobile devices and to test the content validity and reliability of the new questions. The updated questionnaire was named Back Pain and Body Posture Evaluation Instrument for Children and Adolescents (BackPEI-CA). The content was validated by eight experts using the content validity index (CVI). To assess reliability, the BackPEI-CA questionnaire was applied at two different times in 105 school children, and Cohen's kappa (k) and intraclass correlation coefficient (ICC) were calculated. All aspects assessed regarding content validity had a CVI higher than 0.8. The new questions presented moderate and good kappa values and excellent ICC values. The updated version of BackPEI-CA can be used as a clinic tool for assessing the presence, frequency, and intensity of back and neck pain and their risk factors.

RESUMO

Abstract Introduction Children and adolescents with autism spectrum disorder (ASD) present motor disorders that have been the focus of physical therapy interventions. However, the standardized motor assessments available in the literature have important gaps, among them the complexity of the tasks evaluated and the absence of qualitative information about the subjects' performance. Objective To develop and evaluate the content validity of the Gross Motor Assessment of Children and Adolescents with ASD checklist (GMA-AUT checklist). Methods The GMA-AUT checklist was sent to a committee of experts for content validation. The content validity index (CVI) was used to assess the degree of agreement between the experts. To verify the content validity of the checklist, the minimal acceptable CVI was 0.80. Results Based on the suggestions made, the GMA-AUT was reformulated and submitted to the same panel of experts for reassessment. In the second and final draft of the checklist, only two items had a CVI of 0.88, while all others reached a CVI of 1.00. Conclusion The GMA-AUT checklist presents adequate content validity for assessing gross motor in children and adolescents with ASD according to experts in the field.

Resumo Introdução Crianças e adolescentes com transtorno do espectro autista (TEA) apresentam alterações motoras que têm sido foco de intervenções fisioterapêuticas. Contudo as avaliações motoras padronizadas disponíveis na literatura possuem lacunas importantes, entre elas a complexidade das tarefas avaliadas e a ausência de informação qualitativa sobre o desempenho dos sujeitos. Objetivo Desenvolver e avaliar a validade de conteúdo do instrumento "Avaliação Motora Grossa de Crianças e Adolescentes com Transtorno do Espectro Autista" (GMA-AUT). Métodos A versão inicial do instrumento GMA-AUT foi enviada a um comitê de especialistas no tema para a validação de conteúdo através de um questionário. Para avaliar o grau de concordância entre os especialistas, utilizou-se o índice de validade de conteúdo (IVC), sendo IVC de 0,80 o mínimo aceitável. Resultados A partir das sugestões dos especialistas na primeira rodada de avaliação, o GMA-AUT foi reformulado e a partir da segunda, originou-se a versão final. Na versão final do instrumento apenas dois itens apresentaram IVC de 0.88, enquanto todos os demais apresentaram IVC de 1.00. Conclusão O instrumento GMA-AUT apresenta validade de conteúdo adequada para a avaliação motora grossa em crianças e adolescentes com TEA segundo especialistas na área.

RESUMO

INTRODUCTION: Physical exercise improves physical fitness and health, helping to reduce pain and prevent low back pain. This study aims to compare the intensity of low back pain (LBP), behavioral habits, and the level of disability and kinesiophobia among exercising and non-exercising subjects with LBP. METHODS: Consecutive sample of 102 individuals was divided into exercising group (EG) and non-exercising group (NEG). The data was extracted from the answers to the questionnaires Back Pain and Body Posture Evaluation Instrument (BackPEI-A), Oswestry Disability Index (ODI) and Fear-avoidance Beliefs Questionnaire (FABQ-Brazil). For statistical analysis, the chi-square test was used, α ≤ 0.05. RESULTS: Both groups presented predominance of mild to moderate pain intensity and absence of kinesiophobia in the practice of physical activity, with no statistically significant difference. However, there was significant difference between the groups for the risk of occurrence of LBP and for levels of incapacity and kinesiophobia related to work. CONCLUSION: Exercising individuals appear to present with a lower risk for occurrence of LBP, lower level of disability, and absence of work-related kinesiophobia.

RESUMO

INTRODUCTION: Although the pressure biofeedback unit (PBU) is used for muscular assessment and training, there is little evidence of its reproducibility and repeatability. OBJECTIVE: This study aims to assess intra- and inter-rater reproducibility and repeatability of the PBU in the assessment of the transverse abdominal (TrA), internal oblique (IO), low back multifidi, and deep neck flexors (DNF). METHODS: Fifty individuals had three muscular groups tested: TrA/IO, lower back multifidi, and DNF. For repeatability, one rater did three consecutive measures; for intra-rater reproducibility the same rater did two measures with seven-day intervals, and for inter-rater reproducibility, three raters, on the same day, did the measures. Data were analyzed with: Intraclass Correlation Coefficient (ICC), Standard Error of Measurement (SEM), and Minimal Detectable Change (MDC). (α = 0,05). RESULTS: Repeatability: TrA/IO (ICC = 0.847), Multifidi (ICC = 0.860), DNF (ICC = 0.831). Inter-rater reproducibility: TrA/IO (ICC = 0.876), Multifidi (ICC = 0.508), DNF (ICC = 0.442). Intra-rater reproducibility: TrA/IO (ICC = 0.747), Multifidi (ICC = 0.293), DNF (ICC = 0.685). Except for Multifidi, all the SEM values were less than 10 mmHg and the MDC values were less than 15 mmHg. CONCLUSIONS: The PBU can be used with reliability by different evaluators, although the evaluation of multifidi is not indicated.

RESUMO

Owing to the lack of longitudinal studies in Latin American countries, we aimed to evaluate back pain and its risk factors in a 3-year longitudinal study of Brazilian adolescents. We analysed data of 525 adolescents (aged 11-16 years) attending primary school (fifth to eighth grade) in Brazil. The students were administered the self-reported Back Pain and Body Posture Evaluation Instrument (BackPEI) questionnaire in 2011 and at a follow-up evaluation that was conducted 3 years later (2014). Back pain was the outcome variable; the exposure variables included exercise, behavioural, hereditary and postural factors. Generalized estimating equations were used to perform a Poisson regression model with robust variance to evaluate the risk factors for back pain. The prevalence of back pain at baseline was 56% (n = 294); this increased significantly at the 3-year follow-up evaluation to 65.9% (n = 346). The frequency of experiencing back pain also significantly increased after 3 years in both boys (p = 0.002) and girls (p = 0.001). The prevalence of back pain increased significantly in adolescents up to the age of 13 years, stabilized in those aged 14 years and older and was higher among girls. A family history of back pain (in the parents), watching television for lengthy periods and carrying a backpack asymmetrically were predictors for back pain.

RESUMO

Abstract Introduction: There are no studies that investigate whether different workout endings of the Pilates method (PM), either prioritizing the activation of powerhouse muscles or the relaxation of muscles trained during the session, affects spinal curvature. Objective: Identify the immediate effect of a PM session that ends with soft tissue mobilization or wall exercises on the kyphotic and lumbar lordotic angles. Methods: A crossover clinical trial with 19 female Pilates practitioners that used a Flexicurve ruler to evaluate thoracic and lumbar spine curvature before and after a PM exercise protocol, and after endings that involved soft tissue mobilization using massage balls or wall exercises. The order of the different endings was chosen by random draw and the study volunteers participated in two interventions, with intervals of seven to ten days between them. Two two-way ANOVAs were performed (one for each postural variable), using the factors "assessment time" (pre-session; post-PE; post-ending) and "type of ending" (soft tissue or wall exercises). Results: There was no significant difference between the assessment times or endings for the kyphotic (p = 0.972; p = 0.747) and lumbar lordotic angles (p = 0.574; p = 0.627), respectively. Conclusion: Pilates instructors can opt for more relaxing or more active endings without affecting the kyphotic and lumbar lordotic angles.

Resumo Introdução: Ainda não há pesquisas que demonstrem se diferentes maneiras de finalização da sessão no método Pilates (MP), priorizando a ativação da musculatura do power house ou o relaxamento da musculatura trabalhada durante a sessão têm efeito sobre os ângulos de curvatura da coluna. Objetivo: Identificar qual é o efeito imediato de uma sessão do MP finalizada com mobilização de tecidos moles ou com exercícios na parede sobre os ângulos das curvaturas da coluna torácica e lombar. Métodos: Trata-se de um ensaio clínico cruzado, composto por 19 mulheres praticantes de Pilates, que avaliou as curvaturas torácica e lombar através do flexicurva antes e após um protocolo de exercícios do MP, e depois as finalizações de mobilização de tecidos moles através de bolas de massagem e de exercícios na parede. A escolha da ordem das diferentes finalizações foi realizada por sorteio e as voluntárias da pesquisa participaram das duas intervenções com intervalos entre sete e dez dias. Para análise, foram realizadas duas ANOVAs two-way (uma para cada variável postural) com os fatores "momento avaliativo" (pré-sessão; pós-PE; pós-finalização) e "tipo de finalização" (tecidos moles e parede). Resultados: Não houve diferença significativa entre os momentos avaliativos e entre o tipo de finalização para os ângulos da cifose dorsal (p = 0,972; p = 0,747) e da lordose lombar (p = 0,574; p = 0,627), respectivamente. Conclusão: Os profissionais podem propor diferentes formas de finalização, optando por uma finalização mais relaxante ou mais ativa, sem que isso interfira no ângulo das curvaturas torácica e lombar da coluna vertebral.

RESUMO

Abstract Introduction: Spine problems are common, and assessment of spine flexibility provides relevant information; however, alternative evaluation methods need to be validated. Objective: To evaluate the concurrent validity of the Flexicurve using 3D videogrammetry as a reference value to assess spinal flexion and extension in the lumbar and thoracic regions. Method: The consecutive sample consisted of 39 individuals aged between 18 and 50 years. Two consecutive evaluations were performed by the same rater on the same day and at the same location: (1) Flexicurve and (2) 3D videogrammetry. The assessments were performed with the spine in the neutral position, followed by maximum flexion and extension. The range of motion (ROM) in the maximum flexion and extension positions was calculated in MATLAB® and defined as the difference between the maximum flexion or extension angle and that of the neutral position. Statistical analyses used were the Pearson Product-Moment Correlation coefficient, RMS error and Bland-Altman plot (α < 0.05). Results: The ROM between instruments was similar, with high correlations for thoracic flexion (r = 0.751), extension (r = 0.814) and lumbar flexion (r = 0.853), and RMS errors under 8°. The correlation for lumbar extension was moderate (r = 0.613) and the RMS error was more than 10°. The limits of agreement varied between ± 10º and ± 21º. Conclusion: The Flexicurve is valid for assessing maximum flexion and extension of the thoracic spine, and maximum flexion of the lumbar spine. We suggest caution in evaluating the maximum extension of the lumbar spine.

Resumo Introdução: Problemas na coluna vertebral são frequentes, sendo a avaliação da flexibilidade uma informação relevante a ser considerada pelo profissional. Métodos alternativos para realizar avaliação da flexibilidade da coluna carecem de validação. Objetivo: Avaliar a validade concorrente do Flexicurva utilizando a videogrametria 3D como medida de referência, para a avaliação da flexibilidade em flexão e extensão da coluna vertebral torácica e lombar. Método: A amostra consecutiva contou com 39 indivíduos com idades entre 18 e 50 anos. Duas avaliações consecutivas foram realizadas pelo mesmo avaliador no mesmo dia e local: (1) Flexicurva e (2) videogrametria 3D. As avaliações foram realizadas com a coluna na posição neutra, seguida das posições de flexão e extensão máximas. A ADM nas posições de flexão e extensão máximas foram calculadas no MATLAB®, sendo definida como a diferença entre os ângulos máximos de flexão ou extensão e a angulação da posição neutra. Na análise estatística utilizou-se: Teste de Correlação Produto-Momento de Pearson, Erro RMS e Análise de Bland-Altman. (α < 0,05). Resultados: Os valores de ADM entre os instrumentos foram similares, com correlações altas para a flexão torácica (r = 0,751), extensão torácica (r = 0,814) e para flexão lombar (r = 0,853), com erros RMS inferiores a 8°. Para a extensão lombar a correlação foi moderada (r = 0,613), com erro RMS superior a 10°. Limites de concordância variaram entre ± 10º e ± 21º. Conclusão: O Flexicurva mostrou-se válido para avaliar o movimento flexão máxima e extensão máxima da coluna torácica, e flexão máxima da coluna lombar. Sugerimos cautela na avaliação da extensão máxima da coluna lombar.

RESUMO

RESUMO A escoliose é definida como uma deformidade com desvio lateral da coluna no plano coronal, torsão da coluna e do tronco e distúrbio no perfil sagital. Essa alteração postural é avaliada por meio de radiografia de incidência anteroposterior, utilizando-se o método de Cobb. O objetivo do estudo é verificar a influência da experiência do avaliador sobre a confiabilidade intraexaminador e interexaminador do ângulo Cobb em curvaturas escolióticas de crianças. Foram incluídas na pesquisa 39 crianças portadoras de escoliose idiopática, com idade entre 7 e 18 anos. Os exames foram avaliados por dois fisioterapeutas, um quiropraxista e um estudante de fisioterapia - cada um avaliando duas vezes cada exame. A segunda avaliação ocorreu após sete dias, para confiabilidade intraexaminador. Ademais, as primeiras avaliações forneceram dados para confiabilidade interexaminador. A análise estatística foi realizada com coeficiente de correlação intraclasse (CCI), análise de Bland e Altman e análise descritiva do desvio absoluto médio, erro-padrão de medição e mínima mudança detectável. Observou-se boa confiabilidade (CCI>0,5) para as análises intraexaminadores entre os profissionais, e confiabilidade fraca (CCI=0,4) para o avaliador inexperiente. A confiabilidade interexaminador dos profissionais foi boa (CCI=0,6), e com a presença do avaliador inexperiente foi fraca (CCI=0,3). As avaliações entre os profissionais apresentaram menor variabilidade das medidas e valores de desvio-padrão quando comparadas com as do avaliador inexperiente. A mensuração dos ângulos da escoliose por meio do método de Cobb realizada por profissionais experientes apresentou melhores índices de concordância e de confiabilidade intra e interexaminadores e menor desvio-padrão e variabilidade entre as medidas.

El presente estudio tiene como objetivo verificar la influencia de la experiencia del evaluador para la fiabilidad intraexaminador e interexaminador del ángulo de Cobb en las curvaturas escolióticas de los niños. El estudio incluyó a 39 niños con escoliosis idiopática entre 7 y 18 años de edad. Los exámenes fueron evaluados por dos fisioterapeutas, un quiropráctico y un estudiante de fisioterapia, siendo que cada uno evaluó cada examen dos veces. Tras siete días, ocurrió una segunda evaluación para la fiabilidad intraexaminador. Además, las primeras evaluaciones proporcionaron datos para la fiabilidad interexaminador. El análisis estadístico se realizó con el coeficiente de correlación intraclase (ICC), con el análisis de Bland y Altman y con el análisis descriptivo de la desviación media absoluta, del error estándar de medición y del cambio mínimo detectable. Se observó una alta fiabilidad (ICC>0,5) en los análisis intraexaminadores entre los profesionales, y una baja fiabilidad (ICC=0,4) en los de evaluadores inexpertos. La fiabilidad interexaminador de los profesionales fue buena (ICC=0,6), y la presencia del evaluador inexperto fue baja (ICC=0,3). Las evaluaciones entre los profesionales mostraron una menor variabilidad de las medidas y valores de desviación estándar en comparación con los del evaluador inexperto. La medición de los ángulos de escoliosis utilizando el método de Cobb que había sido realizada por profesionales con experiencia mostró mejores índices de concordancia y fiabilidad intra e interexaminadores y una menor desviación estándar y variabilidad entre las mediciones.

ABSTRACT Scoliosis is defined as a deformity with lateral deviation of the spine in the coronal plane, torsion of the spine and trunk, and disturbances in the sagittal profile. This postural alteration is evaluated by anteroposterior incidence radiography using the Cobb method. The objective of this study was to verify the influence of evaluator experience on inter- and intra-rater reliability of the Cobb angle of scoliosis curvatures in children. In total, 39 patients aged 7 to 18 years with idiopathic scoliosis were included in this study. The exams were evaluated by two physical therapists, a chiropractor and a physical therapy student. Each evaluator rated each exam twice and the second evaluation occurred after seven days, characterizing the intra-rater reliability. Furthermore, the first evaluations provided the inter-rater reliability. Statistical analysis was performed with intraclass correlation coefficient (ICC), Bland-Altman analysis, descriptive analysis of mean absolute deviation, standard error of measurement, and minimum detectable chance. Correlations ranged from good (ICC>0.5) for intra-rater reliability among professionals to weak (ICC=0.4) for the inexperienced evaluator. The inter-rater reliability of the professional's evaluations was good (ICC=0.6) and the same analysis with the presence of an inexperienced evaluator was weak (ICC=0.3). Evaluations among professionals showed less variability of measurements and standard deviation values compared to the inexperienced evaluator. The measurement of the angles of the scoliosis through the Cobb method carried out by experienced professionals showed better agreement as well as intra- and inter-rater reliability, lower standard deviation, and variability among the measurements.
