RESUMO

BACKGROUND: home exercise booklets offer several benefits to individuals with shoulder pain. However, it is necessary to investigate the factors that determine adherence to home exercises. OBJECTIVES: 1) To investigate the level of adherence of individuals with chronic shoulder pain to a home exercise booklet conducted without the mediation of a healthcare professional, 2) To describe the barriers and facilitators to adherence, and 3) to determine if shoulder disability, self-efficacy, and treatment expectations are predictors of the level of adherence. DESIGN: prospective longitudinal study. METHODS: A total of 47 individuals with chronic shoulder pain were recruited. The Numeric Pain Rating Scale (NPRS) was used to assess pain intensity, the Shoulder Pain and Disability Index (SPADI) to measure shoulder disability, the Pain Self-Efficacy Questionnaire (PSEQ-10) for self-efficacy, and a likert scale to measure treatment expectations. Adherence was measured by Exercise Adherence Assessment Scale (EAAE-Br). RESULTS: A total of 23 individuals (48.93%) adhered to the home exercise program. The most commonly cited barriers were pain and health-related issues, while the most cited facilitators were pain improvement and symptom relief. Barriers associated with adherence were time constraints and other commitments, while the facilitator associated with adherence was enjoying the exercises. Binary logistic regression analysis revealed that shoulder disability, self-efficacy, and treatment expectations were unable to predict adherence to home exercises in individuals with shoulder pain [F (1,47) = 2.384; p = 0.130; R2 = 0.056]. CONCLUSION: The study revealed barriers and facilitators to home exercise in individuals with shoulder pain. Disability, self-efficacy, and treatment expectations were not able to predict adherence.

RESUMO

OBJECTIVE: The Avoidance of Daily Activities Photo Scale for Patients With Shoulder Pain (ADAP Shoulder Scale) was developed to assess pain-related avoidance behavior during daily activities in people with shoulder pain. However, its measurement properties must be verified according to international guidelines. As such, this study investigated the following 4 measurement properties of the ADAP Shoulder Scale: reliability, measurement errors, convergent validity, and floor and ceiling effects. METHODS: The sample comprised 100 individuals with chronic shoulder pain (43 men and 57 women; mean duration of symptoms of 29.7 [SD = 89.0] months; mean age of 44.9 [SD = 15.9] years). The mean test-retest reliability range was 5 days via the intraclass correlation coefficient (ICC). Measurement errors included the standard error of measurement and the minimal detectable change. Convergent validity was analyzed by applying the Pearson correlation with the Tampa Scale for Kinesiophobia, Pain Catastrophizing Scale, and Shoulder Pain and Disability Index. RESULTS: The ADAP Shoulder Scale showed excellent test-retest reliability, both in all domains and in the total score [ICC(2,1) = 0.94; 95% CI = 0.92-0.96]. The standard errors of measurement for the free-movement, high-effort, and self-care domains were 8.1%, 6.0%, and 7.6%, respectively. The minimal detectable change for the total score of the ADAP Shoulder Scale was 16.0%. The total score of the ADAP Shoulder Scale was low to moderately correlated with the total scores of the Tampa Scale for Kinesiophobia (r = 0.52), Pain Catastrophizing Scale (r = 0.30), and Shoulder Pain and Disability Index (r = 0.72). No floor or ceiling effects were detected in the total score. CONCLUSION: The ADAP Shoulder Scale is a reliable, valid instrument for assessing avoidance behavior in adults who have chronic shoulder pain and are not athletes. IMPACT: This study provides evidence that the ADAP Shoulder Scale is appropriate for clinical and practical use in people with chronic shoulder pain.

RESUMO

BACKGROUND: Causal mediation analysis is one way to bridge this gap by exploring the causal pathways of a given intervention. The aim of this study was to assess whether scapular motion, position, and periscapular muscle strength are mediators for pain and shoulder disability outcomes following a scapular stabilization intervention for patients with subacromial pain syndrome. METHODS: Sixty patients were randomized into two groups: scapular stabilization or periscapular strengthening exercises. The intervention consisted of three sessions per week for 8 weeks. The primary outcome measures were pain and disability and the following outcome measures were considered as potential mediators: scapular motion, scapular position, periscapular muscle strength, age, duration of symptoms, and side of the complaint. A model-based inference approach with bootstrap simulations was used to estimate the average causal mediation effect, average direct effect, and the average total effect from the data of a randomized clinical trial that evaluated the effect of adding scapular stabilization exercises to a scapulothoracic strengthening program in people with subacromial pain syndrome. RESULTS: The results demonstrated that none of the putative mediators were influenced by the intervention. However, muscle strength of serratus anterior, upper, middle, and lower trapezius muscles was associated with shoulder disability. CONCLUSION: Scapular kinematic and periscapular muscle strength did not mediate the effect of scapular stabilization exercises on shoulder pain or disability scores in subjects with subacromial pain syndrome. Muscle strength of serratus anterior, upper, middle and lower trapezius were associated with shoulder disability scores at 8-weeks follow-up.

RESUMO

This cross-sectional study aimed to compare the waveform morphology through noninvasive intracranial pressure (ICP-NI) measurement between patients with migraine and controls, and to analyze the association with clinical variables. Twenty-nine women with migraine, age 32.4 (11.2) years and headache frequency of 12.6 (7.5) days per month and twenty-nine women without headache, age 32.1 (9.0) years, were evaluated. Pain intensity, migraine disability, allodynia, pain catastrophizing, central sensitization and depression were evaluated. The ICP-NI monitoring was performed by a valid method consisting of an extracranial deformation sensor positioned in the patients' scalp, which allowed registration of intracranial pressure waveforms. Heart rate and blood pressure measurements were simultaneously recorded during 20 min in the supine position. The analyzed parameter was the P2/P1 ratio based on mean pulse per minute which P1 represents the percussion wave related to the arterial blood pression maximum and P2 the tidal wave, middle point between the P1 maximum and the dicrotic notch. There was no between-groups difference in the P2/P1 ratio (mean difference: 0.04, IC95%: -0.07 to 0.16, p = 0.352, F (1,1) = 0.881) adjusted by body mass index covariable. The Multiple Linear Regression showed non-statistical significance [F (5,44) = 1.104; p = 0.372; R2 = 0.11)] between the P2/P1 ratio and body mass index, presence of migraine, central sensitization, pain catastrophizing and depression. We found no correlation (p > 0.05) between P2/P1 ratio and migraine frequency, migraine onset, pain intensity, pain intensity at day of examination, disability, allodynia. Migraine patients did not present alterations in the waveform morphology through ICP-NI compared to women without headache and no association with clinical variables was found.

RESUMO

BACKGROUND: Patients with sepsis and immobility in the intensive care unit are associated with muscle weakness, and early mobilisation can counteract it. However, during septic shock, mobilisation is often delayed due to the severity of the illness. Neuromuscular electrical stimulation (NMES) may be an alternative to mobilise these patients early. This study aims to identify whether NMES performed within the first 72 hours of septic shock diagnosis or later is safe from a metabolic perspective. METHODS: This is the analysis of two randomised controlled crossover studies. Patients with acute septic shock (within the first 72 hours of diagnosis) and sepsis and septic shock in the late phase (after 72 hours of diagnosis) were eligible. Patients were submitted in a random order to the intervention protocol (dorsal decubitus position with the lower limbs raised and NMES) and control (dorsal decubitus position with the lower limbs raised without NMES). The patients were allocated in group 1 (intervention and control) or group 2 (control and intervention) with a wash-out period of 4 to 6 hours. Metabolic variables were evaluated by indirect calorimetry. RESULTS: Sixteen patients were analysed in the acute septic shock study and 21 in the late sepsis/septic shock study. There were no significant differences between Oxygen Consumption (VO2) values in the acute phase of septic shock when the baseline period, intervention, and control protocols were compared (186.59 ± 46.10; 183.64 ± 41.39; 188.97 ± 44.88, p>0.05- expressed in mL/Kg/min). The same was observed when the VO2 values in the late phase were compared (224.22 ± 53.09; 226.20 ± 49.64; 226.79 ± 58.25, p>0.05). The other metabolic variables followed the same pattern, with no significant differences between the protocols. When metabolic variables were compared between acute to late phase, significant differences were observed (p<0.05). CONCLUSIONS: As metabolic rates in septic shock patients had no increase during NMES, either in the first 72 hours of diagnosis or later, NMES can be considered safe from a metabolic viewpoint, even despite the higher metabolic demand in the acute phase of shock.

RESUMO

OBJECTIVES: The purpose of this study was to develop the Avoidance of Daily Activities Photo Scale (ADAP Shoulder Scale) to measure shoulder pain-related avoidance behavior in patients with shoulder pain and evaluate and report the structural validity and internal consistency of the scale. METHODS: Potential daily activities involving the shoulder were selected from the activities and participation domain of the International Classification of Functioning, Disability and Health. The selected activities were presented to an expert panel, health care professionals, and patients with shoulder pain with the question "How much do you think it is important to ask patients with shoulder pain about this activity?" Activities attaining a content validity index (CVI) ≥ 0.8 were represented using a digitally colored photograph. Activity photographs were evaluated by health care professionals and patients with shoulder pain. Photographs with a CVI ≥ 0.8 were included in the scale. To evaluate structural validity and internal consistency of the scale, exploratory factor analysis was performed to determine the presence of any scale domain. Cronbach alpha was calculated to indicate the internal consistency of each domain. RESULTS: Of the 107 preselected activities, 21 attained a CVI ≥ 0.8. Eighteen photographs (CVI ≥ 0.8) were included in the scale after being analyzed by 120 health care professionals and 50 patients with shoulder pain. Exploratory factor analysis (N = 156) showed that the ADAP Shoulder Scale consists of 3 domains: free movement, high effort, and self-care. The internal consistencies of the domains were 0.92, 0.89, and 0.92, respectively. CONCLUSION: The ADAP Shoulder Scale included 15 photographs distributed in 3 domains. All domains had a high internal consistency. The scale is easily applicable, well understood, and relevant for shoulder pain. IMPACT: The ADAP Shoulder Scale can be used to rate shoulder pain-related avoidance behaviors.

RESUMO

Autonomic dysfunction, such as reduced vagally mediated heart rate variability, has been suggested in headache patients but is still uncertain when considering primary headache disorders. This study aims to compare the heart rate and blood pressure variability and baroreflex sensitivity between women with migraine and controls. A migraine (n = 20) and a control group (n = 20) of age-matched women without headache were evaluated. Heart rate variability was analyzed through frequency-domain using spectral analysis presenting variance, low-frequency (LF; 0.04-0.15 Hz) and high-frequency (HF; 0.15-0.4 Hz) bands and by time domain (root mean square of successive R-R interval differences, RMSSD). Blood pressure variability was analyzed with spectral analysis and baroreflex sensitivity with the sequence method. Migraine group had lower heart rate variability characterized by a reduction in total variance, LF oscillations (sympathetic/vagal modulation) and HF oscillations (vagal modulation), and a reduction in SD and RMSSD compared to control group. No difference was found in the blood pressure variability analysis. Regarding baroreflex sensitivity, migraine group had decreased values of total gain, gain down and up compared to control group. Women with migraine exhibited autonomic modulation alterations, expressed by decreased values of heart rate variability and baroreflex sensitivity, but not by differences in blood pressure variability.

RESUMO

BACKGROUND: Functional performance tests are inexpensive, accessible, and easy to apply tools that can be used to help practitioners in daily decision making process. The purpose of this study was to evaluate the reliability and validity of the One Arm Hop Test (OAHT) and Seated Medicine Ball Throw Test (SBMT) in young adults. METHODS: Cross-sectional study with a sample consisted of 59 young adults. The subjects performed the OAHT and SMBT in two moments separated by seven days and by two examiners. The Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) was performed at the second moment. The time in OAHT, distance in SMBT, mean number of touches, normalized score, and power of the CKCUEST were measured. Reliability was determined using Intraclass Correlation Coeficient (ICC) and Bland-Altman Plots. Validity was assessed via Pearson's Correlation Coefficient (r) between these tests and CKCUEST. RESULTS: We found good reliability of the OAHT between different raters (dominant limb - ICC = 0.83; non-dominant limb - ICC = 0.80) and moderate reliability between the same rater (dominant limb - ICC = 0.63; non-dominant limb - ICC = 0.62). In the SMBT we found good reliability inter-examiner (ICC = 0.84) and intra-examiner (ICC = 0.77). Low to moderate correlations with the CKCUEST were found (r < 0.70; p < 0.05). CONCLUSIONS: The OAHT and the SMBT show moderate/good reliability intra and inter-examiner, however these tests are poorly correlated with CKCUEST. The SMBT presented higher values of ICC than OAHT. A combination of the SMBT and CKCUEST is recommended in clinical practice.

RESUMO

Subacromial shoulder pain (SSP) accounts for 44-65% of all cases of shoulder pain. Kinematic alterations in the upper limbs have been observed in individuals with SSP, although there is no consensus on such alterations in the literature. Therefore, the present study aimed to compare the three-dimensional kinematics of the scapula, trunk, and arm during shoulder flexion-extension and abduction-adduction movements in individuals with SSP and a control group using statistical parametric mapping (SPM). We evaluated 117 participants [61 with SSP and 56 in the control group (CG)]. The three-dimensional kinematic analysis was performed starting from arm extension/adduction (0%), moving to flexion/abduction, and ending returning to extension/adduction, respectively (100%) in both groups. SSP group flexed more their trunk (0-100%, p < 0.001) and rotated scapula internally (0-20%, p < 0.001 and 75-100%, p < 0.001); rotated upwards (17-32%, p < 0.005 and 58-87%, p < 0.003) and posteriorly tilted (28-79%,p < 0.001 and 81-95%,p < 0.006) less than CG group during arm abduction-adduction. Through arm flexion-extension, the SSP group flexed (38-82% p < 0.009) less their trunk, rotated upwards (5-10% p = 0.021) less their scapula, and posteriorly tilted scapula (0-100% p < 0.001) more than CG. Combining conventional variables used to describe motion in individuals with SSP, such as minimum and maximum values, range of motion, and results provided by SPM can furnish a detailed description of the compensations and limitations of the patient, enabling a better understanding of the function of the scapular girdle as well as improvements in the evaluation process and clinical decision making.

RESUMO

BACKGROUND: Synergism between shoulder and trunk muscles seems to be effective to increase periscapular muscle activation in asymptomatic subjects. The influence of conscious contraction of the abdominal muscles has not yet been studied in non-athlete subjects with pain. The study aimed to investigate the effect of the instruction for conscious activation of the abdominal muscles on the activity of the scapulothoracic muscles during shoulder exercises in subjects with subacromial pain syndrome. METHOD: Thirty subjects with unilateral pain (mean age 52 ± 11 years) participated in this study. Three isometric and five dynamic exercises for the scapulothoracic muscles were assessed. The group without instruction just repeated the exercises, while the instruction group was evaluated before and after conscious abdominal training. The linear mixed model analysis was used to compare the muscle activation between groups. FINDINGS: Differences between groups after the conscious abdominal contraction for activation of middle and lower trapezius on the symptomatic side in the "Full can"(p = 0.03; effect size:0.92 middle trapezius); (p = 0.02; effect size:0.96 lower trapezius) and "Knee Push" (p = 0.01; effect size:0.75 lower trapezius). For asymptomatic side, the exercises "External Rotation Kneeling" (p = 0.04; effect size: 0.81 lower trapezius); (p = 0.00; effect size: 2.09 serratus anterior), "Knee Push" (p = 0.04; effect size:1.24 serratus anterior) and "Wall Slide" (p = 0.01; effect size: 1.03 serratus anterior). INTERPRETATION: Conscious contraction of the abdominal muscle immediately alter the activation of the serratus anterior muscle during closed kinetic chain exercises on the asymptomatic side and increased activation of trapezius on the symptomatic side during shoulder open kinetic chain exercise.

RESUMO

PURPOSE: The purpose of this study was to determine the minimal detectable change (MDC) and responsiveness of the Perme Score when used in the adult intensive care unit (ICU) population. METHODS: This is a prospective longitudinal study which was conducted from November 2016 to July 2017 in Cali, Colombia. Four physical therapists with observer and evaluator roles, applied the Perme Score upon ICU admission and discharge. The Consensus-based Standards for the Selection of Health Measurement Instruments Protocol standards to analyze sensitivity to change were used. The sample size was defined considering the lowest concordance proportion reported (68.6%), and a Kappa Index of 0.2784 or higher to guarantee an adequate n, and a 95% reliability level. RESULTS: One hundred and forty-two patients were enrolled in the study. There were 51.4% men with an average age of 58 ± 17 years. Invasive mechanical ventilation was employed in 42.0% of the patients. The MDC for the Perme Score was 1.36, and 80% of patients demonstrated higher or equal values, detecting a significant difference in the type of weaning and the length of stay in the ICU (p < 0.005). CONCLUSIONS: The Perme Score has an MDC of 1.36 points and shows evidence of being sensitive to change. Therefore, the findings validate the responsiveness of the instrument.

RESUMO

OBJECTIVE: This study aimed to verify a possible relationship between shoulder disability and shoulder pain intensity and the variables related to cervical-spine dysfunction, and determine which of these can differentiate moderate to severe shoulder pain (>4 on a numerical rating scale [NRS]) from mild shoulder pain (≤4 on the NRS) in individuals with subacromial impingement symptoms. METHODS: One hundred and forty volunteers with shoulder pain were evaluated. Demographic information and variables related to the shoulder and neck were collected. Self-reported pain and disability of the shoulder and cervical spine were measured using the Shoulder Pain and Disability Index (SPADI) and Neck Disability Index (NDI) questionnaires, respectively. An NRS was used to measure pain in the shoulder and cervical spine. A purposeful modeling strategy was used to determine the best model to predict shoulder disability and shoulder pain (dependent variables). Multiple logistic regression analysis followed by receiver operating curve analysis was used to determine which variables better differentiated moderate to severe shoulder pain from mild shoulder pain. RESULTS: Variables such as Neck Disability Index (NDI) score (ß = 1.09, P = .00) and age (ß = -0.19, P = .03) were associated with the total SPADI score. Neck pain was significantly associated with shoulder pain (ß = 0.40, P = .00). The combination of variables predicting moderate to severe shoulder pain was total SPADI score (odds ratio [OR] = 1.15, P = .003), neck pain (OR = 3.20, P = .04), and age (OR = 1.01, P = .05). CONCLUSION: Our results demonstrate the important connection between shoulder- and neck-related symptoms in individuals with subacromial impingement symptoms.

RESUMO

OBJECTIVE: To investigate the effect on shoulder pain and disability of teaching patients with shoulder pain how to undertake a home-based exercise program. DESIGN: A randomized controlled trial conducted from September 2015 to January 2016. SETTING: Participants' home. PARTICIPANTS: Sixty participants with shoulder pain who were waiting for physiotherapeutic treatment. INTERVENTIONS: The control group (n = 30) received minimal education about their shoulder condition and instructions to continue their activities as normal. The intervention group (n = 30) received a two-month home exercise program with one-hour sessions delivered by a physiotherapist to begin and one month after the program for exercise instructions. MAIN MEASURES: The primary outcome was change in the Shoulder Pain and Disability Index (SPADI). The secondary outcomes included change in the numeric pain rating scale and medication intake for pain relief. RESULTS: The patients' average age was 54.3 (13.8) years. SPADI scores at baseline were 60.9 (16.5) in the intervention and 64.7 (15.3) in the control group. After two months, the SPADI scores decreased to 18.8 (28.6) and to 61.4 (24.0), respectively, in the intervention and control groups with an estimated mean difference of 40.0, effect size: 1.61. The intervention group showed a reduced pain intensity (estimated mean difference: 3.7, effect size: 2.43) and medication intake (chi-square: 0.001). The number needed to treat was 1.2 for one patient to have a SPADI score <20. CONCLUSION: Teaching patients with shoulder pain how to undertake a home-based exercise program improved shoulder function and reduced pain intensity and medication intake over two months.

RESUMO

BACKGROUND: This study aimed to adapt the Exercise Adherence Rating Scale (EARS) into Brazilian Portuguese and evaluate its measurement properties, given as reliability, validity, and responsiveness in patients with non-specific Chronic Low Back Pain (CLBP). METHODS: A total of 108 patients with a mean age of 46.62 years (SD = 9.98) and CLBP participated in this longitudinal study. Participants were oriented on undertaking the prescribed exercises in the first session, and adherence behavior was assessed after 1 week, and finally reassessed after 2 weeks (test-retest reliability). Three weeks after the first assessment, they were invited again to full fill the EARS (responsiveness). The intraclass correlation coefficient (ICC2,1) and Cronbach's α were used to assess test-retest reliability and internal consistency, respectively. Spearman's correlation and confirmatory factor analysis (CFA) were used to assess construct validity, and the Receiver operating characteristic curve and area under the curve (AUC) were used to analyze responsiveness. RESULTS: The one-factor EARS-Br (adherence behavior) structure with 6 items showed acceptable fit indexes (comparative fit index and goodness of fit index> 0.90 and root-mean-square error of approximation< 0.08). The EARS-Br scale showed acceptable internal consistency (α = 0.88) and excellent reliability (ICC = 0.91 [95% CI 0.86-0.94]). Mild to moderate correlations were observed between EARS-Br total score vs. disability, pain catastrophizing, depression/anxiety, fear-avoidance and pain intensity. A Minimally Important Change (MIC) of 5.5 in the EARS-Br total score was considered as a meaningful change in the adherence behavior (AUC = 0.82). Moderate accuracy (AUC = 0.89) was obtained for a 17/24 total EARS cutoff score after home exercise was prescribed. The sensitivity and specificity were also acceptable (greater than 80%). CONCLUSION: Our results demonstrated acceptable EARS-Br reliability, validity, and responsiveness for patients with CLBP. A final score of 17/24 on EARS after the prescription of home-exercise could be used as a cut-off for an acceptable adherence behavior associated with improvement in patient outcomes.

RESUMO

OBJECTIVES: This study aimed to investigate self-efficacy levels of patients after finishing rehabilitation for chronic musculoskeletal conditions and identify factors related to self-efficacy. METHOD: Two hundred and eight patients aged >40 years with musculoskeletal disorders were included. Self-efficacy was assessed by the Chronic Pain Self-Efficacy Scale (CPSS), and regression analyses were used to test six predictors of self-efficacy: age, symptom duration, number of physical therapy sessions, postdischarge pain intensity, perceived clinical improvement, and cognitive reassurance. Self-efficacy was compared between patients who reported improvement and worsening of their clinical condition, and a cutoff value for self-efficacy was established using receiver operating characteristic curve analyses to distinguish patients with severe pain from those with mild to moderate pain. RESULTS: Better perceived clinical improvement (Beta = -0.37, p = 0.000), lower pain intensity (Beta = -0.33, p = 0.000), and a lower number of physical therapy sessions (Beta = -0.12, p = 0.027) were related to greater self-efficacy. No significant associations were observed between self-efficacy and age, symptom duration, and cognitive reassurance. The patients who reported improvement had greater self-efficacy (204.76 ± 52.80) than those who reported worsening of their clinical condition (145.45 ± 44.18; p = 0.000). A CPSS score of 172 points (sensitivity of 0.77; specificity of 0.72) may indicate low self-efficacy. CONCLUSION: A higher perception of self-efficacy after discharge from physiotherapy is associated with better perceived clinical improvement, lower pain intensity, and a lower number of physical therapy sessions. Therefore, interventions to support patients' exercise-based rehabilitation should include self-efficacy, which may affect the prognosis of patients with chronic conditions.

RESUMO

The relationship between shoulder pain and scapular dyskinesis (SDK) is unclear. Differences between groups with and without SDK have been demonstrated, focusing on the amount of scapular motion at specific degrees of humeral elevation. However, this approach does not consider the temporal information and shape of the scapular motion temporal series. Principal Component Analysis (PCA) may clarify this variability and advance current understanding of 'abnormal' movement patterns. This study aimed to evaluate the scapular kinematics in patients with shoulder pain and in asymptomatic participants with and without SDK using PCA. Data were collected in 98 participants separated in four groups: Pain + SDK (n = 24), Pain (n = 25), No Pain + SDK (n = 24), and No Pain (n = 25). Scapulothoracic kinematic data were measured with an electromagnetic tracking device during arm elevation and lowering phases. PCA and analysis of variance were used to compare the groups. The No Pain + SDK group had a progressive increasing in anterior tilt over the elevation phase compared to the Pain (effect size = 0.79) and No Pain (effect size = 0.80) groups. During the arm-lowering, the Pain + SDK group had a progressive increasing in anterior tilt over this phase in comparison to the No Pain + SDK group (effect size = 0.68). Therefore, PCA demonstrated differences in the scapular anterior tilt related to SDK and shoulder pain. The presence of SDK revealed a scapular pattern with progressive increasing in anterior tilt over the elevation phase. However, during the arm-lowering phase, asymptomatic participants with SDK changed their motion pattern, unlike the symptomatic group, reinforcing the suggested association between scapular modifications and shoulder symptoms.

RESUMO

INTRODUCTION: Septic shock is a potentially fatal organ dysfunction caused by an imbalance of the host response to infection. The changes in microcirculation during sepsis can be explained by the alterations in the endothelial barrier function. Endothelial progenitor cells (EPCs) are a potential recovery index of endothelial function and it an increase in response to neuromuscular electrical stimulation (NMES) was demonstrated. Therefore, the objective of this study is to investigate the effects of NMES in patients with septic shock. METHODS AND ANALYSIS: It is a study protocol for a randomized cross-over design in an intensive care unit of a tertiary University hospital. Thirty-one patients aged 18 to 65 years. The study will be divided in 2 phases: the phase one will be held in the first 72 hours of septic shock and the phase two after 3 days of first assessment. Patients will be randomly selected to the intervention protocol (decubitus position with the limbs raised and NMES) and control protocol (decubitus position with the limbs raised without NMES). After this procedure, the patients will be allocated in group 1 (intervention and control protocol) or group 2 (control and intervention protocol) with a wash-out period of 4 to 6 hours between them. The main outcome is mobilization of EPCs. The secondary outcome is metabolic and hemodynamic data. A linear mixed model will be used for analysis of dependent variables and estimated values of the mean of the differences of each effect.

RESUMO

Clinical evaluation of scapular dyskinesis (SD) aims to identify abnormal scapulothoracic movement, underlying causal factors, and the potential relationship with shoulder symptoms. The literature proposes different methods of dynamic clinical evaluation of SD, but improved reliability and agreement values are needed. The present study aimed to evaluate the intrarater and interrater agreement and reliability of three SD classifications: 1) 4-type classification, 2) Yes/No classification, and 3) scapular dyskinesis test (SDT). Seventy-five young athletes, including 45 men and 30 women, were evaluated. Raters evaluated the SD based on the three methods during one series of 8-10 cycles (at least eight and maximum of ten) of forward flexion and abduction with an external load under the observation of two raters trained to diagnose SD. The evaluation protocol was repeated after 3 h for intrarater analysis. The agreement percentage was calculated by dividing the observed agreement by the total number of observations. Reliability was calculated using Cohen Kappa coefficient, with a 95% confidence interval (CI), defined by Kappa coefficient ±1.96 multiplied by the measurement standard error. The interrater analyses showed an agreement percentage between 80% and 95.9% and an almost perfect reliability (k>0.81) for the three classification methods in all the test conditions, except the 4-type and SDT classification methods, which had substantial reliability (k<0.80) in shoulder abduction. Intrarater analyses showed agreement percentages between 80.7% and 89.3% and substantial reliability (0.67 to 0.81) for both raters in the three classifications. CIs ranged from moderate to almost perfect categories. This indicates that the three SD classification methods investigated in this study showed high reliability values for both intrarater and interrater evaluation throughout a protocol that provided SD evaluation training of raters and included several repetitions of arm movements with external load during a live assessment.

RESUMO

Esse estudo teve como objetivo caracterizar o Perfil de Estilo de Vida Individual (PEVI) de indivíduos com dor no ombro em relação à atividade física (AF), nutrição, controle do estresse, relacionamento social e comportamento preventivo e verificar a correlação entre o componente AF do PEVI e o domínio de incapacidade avaliado pelo Shoulder Pain and Disability Index (SPADI). Trata-se de um estudo transversal, com 100 indivíduos adultos e idosos com dor no ombro (55,3 ± 12 anos, 83% mulheres) atendidos em um serviço público de fisioterapia em 2015/2016. Os indivíduos responderam ao questionário PEVI e ao SPADI para avaliação da dor e incapacidade do ombro. Os resultados indicam que 84% dos avaliados apresentaram PEVI de regular a ruim (pontuação ≤ 33), sendo positivo (pontuação média = 2 a 3) para comportamento preventivo e relacionamento social em 94% e 53% dos indivíduos, respectivamente. Nos demais componentes, as respostas se concentraram no perfil regular (pontuação média = 1 a 1,99) e positivo, mas o componente AF apresentou o maior número de indivíduos (30%) com perfil negativo (pontuação média < 1) e identificou que a maioria não realiza AF moderada a intensa e exercícios de força e alongamento muscular. Os níveis de incapacidade do ombro e de AF apresentaram uma correlação baixa (-0,179; p=0,040). Em conclusão, indivíduos com dor no ombro apresentam estilo de vida regular, sendo importante incentivar a prática de atividade física para melhora da qualidade de vida.

This study aimed to characterize the Individual Lifestyle Profile (PEVI) of individuals with shoulder pain in relation to physical activity (PA), nutrition, stress management, social relationship and preventive behavior and to verify the correlation between PA component of PEVI and the disability domain assessed by the Shoulder Pain and Disability Index (SPADI). This is a cross-sectional study with 100 adult and elderly individuals with shoulder pain (55.3 ± 12 years, 83% female) attending in a public physiotherapy service in 2015/2016. Individuals answered the PEVI questionnaire and SPADI for shoulder pain and disability assessment. The results indicate that 84% of the patients presented PEVI from regular to poor (score ≤ 33), and positive (mean score = 2 to 3) for preventive behavior and social relationships in 94% and 53% of the individuals, respectively. For the other components, responses were concentrated in the regular profile (mean score = 1 to 1.99) and positive, but the PA component had the highest number of individuals (30%) with a negative profile (mean score <1) and identified most do not perform moderate to intense PA and muscle strength and stretching exercises. Shoulder disability levels and PA showed a low correlation (-0.179; p = 0.040). In conclusion, individuals with shoulder pain present a regular lifestyle, and it is important to encourage the practice of physical activity to improve the quality of life.

RESUMO

PURPOSE: The study aimed to investigate the effect of the instruction for conscious contraction of the abdominal muscles on the scapulothoracic muscles activation during shoulder exercises. DESIGN: Repeated measures design in a single group, pre-post instruction. METHODS: Sixty healthy male and female subjects (mean age 23.5 ± 3 years) volunteered for this study. Two isometric and three dynamic exercises for the scapulothoracic muscles, focusing on the serratus anterior muscle were assessed before and after familiarization training, standardized verbal, and tactile feedback applied to encourage abdominal muscle contraction. Repeated measures ANOVA and Bonferroni post-hoc test were used to compare normalized EMG amplitudes. RESULTS: Instruction increased EMG amplitude only for serratus anterior muscle during isometric exercises (Inferior Glide and Isometric Low Row). Conscious contraction of the abdominal muscles resulted in significant increase (p < 0.05) in the serratus anterior, upper, middle and lower trapezius EMG amplitude, during dynamic exercises (Wall Slide, Wall Press, and Knee Push-Up). CONCLUSION: Conscious contraction of the abdominal muscle increased the activation of the serratus anterior e the three parts of the trapezius during dynamic shoulder exercises with moderate to minimal levels of EMG activation. In the other hand, abdominal muscles contraction was effective to increase the activation of the serratus anterior during isometric exercises but did not increase the trapezius activation. So, Inferior Glide and Isometric Low Row performed along with encouraged abdominal muscle contraction are compatible to initial phases of the serratus anterior strengthening with low levels of upper trapezius muscle activation.
