RESUMO

PURPOSE: To develop a new instrument to identify barriers to self-administered home-based task-oriented practice post-stroke and test its content validity. MATERIALS AND METHODS: The sample consisted of individuals with stroke and neurological rehabilitation professionals. The study consisted of two steps: (1) Instrument development, involving three processes; a data search in the literature, interviews with the target population and an open questionnaire (online) sent to professionals; and (2) Testing the content validity of the instrument by asking individuals with stroke and professionals about the comprehensiveness and relevance of the items and additionally asking individuals with stroke about the comprehensibility of the items. For each item in the instrument, the threshold validity scores were ≥0.80 in the Content Validity Index and ≥0.75 for the Kappa agreement. RESULTS: The preliminary version was developed with 46 items. The content validation was performed in three rounds. The last version of the instrument Barriers to self-administered home-based task-oriented practice post-stroke (BASH-TOP-Stroke) contained 34 items in five response categories, in which the higher the value presented, the greater the number of barriers. The content validity for the items was excellent. CONCLUSIONS: The study provides a new instrument to help identify barriers to self-administered home-based task-oriented practice post-stroke.

Barriers to self-administered task-oriented home-based exercises can be specific to this form of practice.Understanding barriers to self-administered task-oriented home-based exercises is essential to increase the amount of practice for optimizing motor recovery.The Barriers to self-administered home-based task-oriented practice post-stroke (BASH-TOP-Stroke) questionnaire was developed to evaluate barriers to self-administered task-oriented home-based exercises in individuals post-stroke.BASH-TOP-Stroke has excellent content validity based on patients and professionals and could help to identify strategies that may reduce barriers to self-administered home-based task-oriented practice after stroke.

RESUMO

BACKGROUND: Due to its multiple benefits in Parkinson's Disease, Dance has been a widely recommended activity in rehabilitation. However, there is a gap in the literature on the use of Brazilian sytles in rehabilitation protocols. This study aimed to compare the effect of 2 different protocols of Brazilian dance, samba and forró, and samba on motor aspects and quality of life of individuals with Parkinson's disease. METHODS: In a nonrandomized clinical trial lasting 12 weeks, 69 individuals with Parkinson's disease participated in the study: forró and samba group (FSG = 23), samba group (SG = 23), and control group (CG = 23). RESULTS: Significant improvements were found after SG intervention in the UPDRSIII and in the subitem quality of life mobility. In intra-group comparisons of FSG, significant differences were found in the subtype of quality of life discomfort. In the intergroup analysis, significant differences were found between CG, SG, and FSG in the communication sub-item, showing a greater increase in the scores of the groups that participated in the SG and FSG. CONCLUSIONS: The findings of this study suggest that Brazilian dance practice is capable of improving the perception of some aspects of quality of life and motor symptoms in relation to controls in people with Parkinson's disease.

RESUMO

Background: People with Parkinson's disease (PD) need to exercise to have a better quality of life. The risk of falling needs to be considered when choosing and implementing exercise interventions. Flowcharts are used to facilitate referrals in Brazilian primary care network, but there is no specific one for PD. Aim: To develop a referral flowchart for people with PD in Brazilian primary care based on the risk of falls and scientific evidence in the context of a multidisciplinary approach. Methods: The development of the referral flowchart was accomplished in three steps; (1) relevant literature was reviewed (2) semi-structured interviews (in focus groups) were conducted with primary health care professionals to investigate the current care for people with Parkinson's disease, and (3) the information obtained from the previous steps were analyzed to inform the development of the referral flowchart. Results: The fall risk-based flowchart uses the 3-step-fall-prediction tool. The primary health care professional should refer the person with a low risk of falls to activities with minimal supervision and those with a higher risk of falls to specialized neurology services. Neurology services are also the referral target for persons presenting significant mobility restrictions (i.e., restricted to a wheelchair or bed). The referral occurs according to what is available in Brazilian primary care. Conclusion: This flowchart might be the first step to build a multidisciplinary approach for people with Parkinson's disease in Brazilian primary care. The next stage of this study is the validation and subsequent implementation of the flowchart through the primary care at Unified Health System in Brazil.

RESUMO

BACKGROUND: Young people tend to spend most of their time in activities involving inappropriate positions, which can promote musculoskeletal alterations and disorders. OBJECTIVE: To investigate the prevalence of low back pain (LBP) in young people and analyse its associations with daily postural habits. METHODS: Cross-sectional and retrospective study evaluating 679 Brazilian young people (15 to 18 years old), using questionnaires about LBP and awareness of postural habits. The prevalence values were calculated for the present moment, the last three months and throughout life. The Mann-Whitney U test and the Chi-square test were applied. RESULTS: The prevalence of LBP at the present moment was 27.2%, 57.7% over the last three months and 73.9% throughout life. Boys and girls presented significantly different values, a larger number of girls manifesting pain for the three moments. The associated postural habits were: turning the body, reduction of lumbar lordosis when seated, not placing the feet on the floor, crossing the legs when sitting in the classroom and at home, sitting or lying in an inappropriate position, and distributing the body asymmetrically on the legs when standing. CONCLUSIONS: Young people from 15 to 18 years of age show a high prevalence of low back pain. Inadequate postural habits adopted during everyday activities are associated with this complaint. These findings could contribute to the implementation of prevention and rehabilitation strategies.

RESUMO

Abstract Aim: People with Parkinson's disease constantly demonstrate low levels of physical activity, which is why dance has become increasingly important for the treatment of the disease. This study aimed to analyze the influence of binary and quaternary rhythm on fatigue, sleep, and daytime sleepiness in individuals with Parkinson's disease. Methods: 31 individuals participated in this randomized clinical trial with a mean age of 66.6 ± 10.2 years, 71% were male and 29% were female, allocated into two groups, binary and quaternary, where they participated in different dance interventions lasting 12 weeks. A questionnaire was applied including personal and clinical information; Mental State Mini-Examination (MMSE), Hoehn and Yahr (H&Y), Fatigue Severity Scale (FSS), Sleep Scale for Parkinson's Disease (PDSS), and Daytime Sleepiness Epworth Scale (ESS). Results: The groups that participated in binary rhythm classes showed improvement in sleep quality and daytime sleepiness after 12 weeks of intervention. However, no significant differences were found in the group that participated in the quaternary rhythm classes. Moreover, it was noted that the binary group managed to raise the heart rate during the 12 weeks of intervention, given that these results were not obtained in the quaternary group. Conclusion: The results showed the effectiveness of binary rhythm on non-motor symptoms and heart rate increase in individuals with Parkinson's disease. Thus, it is concluded that the binary rhythm was more effective than the quaternary rhythm.

RESUMO

BACKGROUND: Transcranial direct current stimulation (tDCS) has the potential to modulate cortical excitability and enhance the effects of walking training in people with Parkinson's disease. This study will examine the efficacy of the addition of tDCS to a task-specific walking training to improve walking and mobility and to reduce falls in people with Parkinson's disease. METHODS: This is a two-arm, prospectively registered, randomized trial with concealed allocation, blinded assessors, participants and therapists, and intention-to-treat analysis. Twenty-four individuals with Parkinson's disease, categorized as slow or intermediate walkers (walking speeds ≤ 1.0 m/s), will be recruited. The experimental group will undertake a 30-min walking training associated with tDCS, for 4 weeks. The control group will undertake the same walking training, but with sham-tDCS. The primary outcome will be comfortable walking speed. Secondary outcomes will include walking step length, walking cadence, walking confidence, mobility, freezing of gait, fear of falling, and falls. Outcomes will be collected by a researcher blinded to group allocation at baseline (week 0), after intervention (week 4), and 1 month beyond intervention (week 8). DISCUSSION: tDCS associated with walking training may help improve walking of slow and intermediate walkers with Parkinson's disease. If walking is enhanced, the benefits may be accompanied by better mobility and reduced fear of falling, and individuals may experience greater free-living physical activity at home and in the community. TRIAL REGISTRATION: Brazilian Registry of Clinical Trials (ReBEC) RBR-6bvnx6 . Registered on September 23, 2019.

RESUMO

This study aimed to compare the effect of a binary and quaternary rhythm protocol on cognition, mental activity, daily life, and quality of life among individuals with Parkinson's Disease. A two-arm randomized clinical trial with 31 individuals diagnosed with Parkinson's disease, who were allocated to the binary group or quaternary group. Both groups underwent a 12-week intervention. The following variables were analyzed: personal and clinical information; MoCA; UPDRSI and II; PDQ-39. Both intervention groups improved cognition, mental activity, activities of daily living, and quality of life. In addition, there were intergroup differences in total UPDRSII, writing, and hygiene where the quaternary group was superior to the binary group. It concludes that the binary and quaternary rhythm positively influenced and presented similar effects on the complementary treatment of individuals with Parkinson's disease on the studied variables. Thus, it is believed that both interventions are possible and feasible for the health professionals involved in the area.

RESUMO

This non-randomized clinical trial aimed to analyze the impact of the Brazilian samba training protocol on the balance and quality of life of people with Parkinson's disease. Forty-seven individuals participated, with a mean age of 68 ± 9.3 years-old, 24 from the control group (CG) and 23 from the experimental group (EG). The CG was formed by those who did not participate in the interven-tion, and the EG by individuals who participated in the Brazilian samba dance protocol. This study was divided into pre-intervention (before 12 weeks) and post-intervention (after 12 weeks) with a questionnaire consisting of: Mini Mental State Examination (MMSE); Unified Parkinson's Disease Rating Scale (UPDRS); Quality of life (PDQ-39); Berg's Balance Scale; Perception of perceived changes. The results point to a significant improvement after the intervention in the UPDRS (p < 0.001) and balance (p = 0.006) of the EG; in the quality of life of the EG after intervention in the mobility (p = 0.009) and total (p = 0.034) domains; and in the post-intervention period in the cog-nitive (p = 0.025) and communication (p = 0.032) domains of the EG and CG. Thus, it is concluded that the Brazilian samba rhythm has been shown to be effective in improving the total UPDRS, balance and quality of life, as well as in mobility, cognition and communication

RESUMO

INTRODUCTION: Parkinson's disease (PD) leads to deficits in upper limb strength and manual dexterity and consequently resulting in functional impairment. Handgrip strength is correlated with the motor symptom severity of the disease, but there is a gap in the literature about the influence of freezing in PD patients. OBJECTIVE: The objective is to study the correlation between handgrip strength and motor symptom severity considering the freezing phenomenon and to verify variables that can predict Unified Parkinson's Disease Rating Scale (UPDRS) III. METHODS: This is a multicenter cross-sectional study in PD. 101 patients were divided into 2 groups: freezing of gait (FOG) (n = 51) and nonfreezing (nFOG) (n = 52). Freezing of Gait Questionnaire (FOGQ); UPDRS II and III sections; Hoehn and Yahr (HY) scale; handgrip dynamometry (HD); 9 Hole Peg Test (9-HPT) were assessed. RESULTS: In both groups, HD was correlated to UPDRS III (nFOG: -0.308; FOG: -0.301), UPDRS total (nFOG: -0.379; FOG: -0.368), UPDRS item 23 (nFOG: -0.404; FOG: -0.605), and UPDRS item 24 (nFOG: -0.405; FOG: -0.515). For the correlation to UPDRS II (0.320) and 9-HPT (-0.323), only nFOG group presented significance. For the UPDRS 25 (-0.437), only FOG group presented statistical significance. The UPDRS III can be predicted by 9-HPT, age, and HY in nFOG patients (Adjusted R2 = 0.416). In FOG group, UPDRS III can be predicted by HD, 9-HPT, age, and HY (Adjusted R2 = 0.491). CONCLUSION: Handgrip strength showed to be predictive of motor impairment only in the FOG group. Our results showed clinical profile differences of motor symptoms considering freezers and nonfreezers with PD.

RESUMO

Parkinson's disease (PD) has numerous motor and non-motor symptoms. Among non-motor manifestations impulse control disorders (ICDs) stand out. ICDs include compulsions for gambling, shopping, eating, and sexual behavior, and "related disorders" such as hobbyism, simple motor activities, and dopamine dysregulation syndrome. There is no rating scale translated and adapted transculturally into Brazilian Portuguese language. Therefore, we cross-culturally adapted and investigated the measurement properties of the Brazilian version of the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale (QUIP-RS). Fifty-three patients participated in the study. Inter-evaluator and test-retest (patient and health professional) reliabilities (intraclass correlation coefficient) were all excellent (0.93, 0.93, and 0.99). The internal consistency was high (α = 0.92). The Minimal detectable change (MDC) value was 5.8 (patient) and 2.3 (health professional) points. There was a floor, but no ceiling, effect. In summary, the Brazilian version of the QUIP-RS has high reliability and content validity.

RESUMO

OBJECTIVE: To investigate the feasibility of a Brazilian samba protocol in individuals with Parkinson's disease. METHODS: Twenty participants, mean age of 66.4±10.7 years, diagnosed with idiopathic Parkinson 's disease, divided into: experimental group that received the intervention of Brazilian samba dance classes (10 individuals); and control group that maintained their routine activities (10 individuals). For data collection, a divided questionnaire was used: General Information; Disability stages scale; Balance and Quality of Life. RESULTS: During class implementation, there were no falls, as all dance activities adhered to the details of the protocol steps without any changes. On average, patients completed 82.7% of activities. After 12 weeks, the experimental group had improvements in the UPDRS global score, in daily activities, and on motor examination. There was also improvement in balance scores and in the mobility domain of the quality of life in the experimental group. CONCLUSION: The samba protocol seems to be feasible and safe for patients with PD. Moreover, it has pleasant characteristics and offers sufficient physical benefits for combination with drug treatment. There were also benefits in social relationships and as a possible rehabilitation tool in individuals with Parkinson's disease.

RESUMO

ABSTRACT Introduction: People with Parkinson's disease constantly have low levels of physical activity. Dancing has become increasingly important for treating the disease and can help improve non-motor symptoms. Objective: To analyze the influence of Brazilian samba on the non-motor symptoms of PD according to TD and PGID subtypes. Methods: A 12-week, non-randomized clinical trial, through comparison with a control group. The 23 individuals who agreed to participate in the activities formed the experimental group (EG) and the 24 individuals who opted not to participate in the Brazilian samba classes comprised the control group (CG). A questionnaire was applied, composed of validated instruments. Mini Mental State Examination - MMSE; HY - Disability Scale; Unified Parkinson's Disease Rating Scale - UPDRS 1 and total values; Parkinson's Disease Questionnaire - PDQ-39, Parkinson's Disease Sleep Scale - PDSS; Beck Depression Inventory - BDI; Fatigue Severity Scale - FSS and Magnitude of Perceived Changes. Results: After the twelve weeks of intervention, it was observed that the EG showed improvement in the scores of all the tests. The comparison between groups, however, indicated a significant difference in the post-UPDRS1 period in which the EG presented improvement in cognitive impairment, while the CG presented a deficit in these values. The results of the division between disease subtypes show a greater change in the values between individuals of the TD group, when comparing the EG with the CG. For the EG, the greatest difference between pre- and post- intervention was fatigue. Conclusion: There was a positive trend in all the variables studied after the application of the protocol. This demonstrates that interventions such as dance may have greater effects on non-motor symptoms, depending on the expected progression of the disease. The scarcity of studies that use this approach in their analyses may explain the lack of evidence in this symptomatology related to dance.

RESUMO Introdução: As pessoas com doença de Parkinson constantemente apresentam baixos níveis de atividade física. A dança tem se tornado cada vez mais importante para o tratamento da doença e pode ajudar a melhorar os sintomas não motores. Objetivo: Analisar a influência do samba brasileiro nos sintomas não motores da DP, segundo os subtipos TD e PGID. Métodos: Ensaio clínico não randomizado com duração de 12 semanas por meio de comparação com grupo controle. Os 23 indivíduos que aceitaram participar das atividades formaram o grupo experimental (GE) e os 24 indivíduos que optaram por não participar das aulas de dança brasileira formaram o grupo controle (GC). Um questionário foi aplicado, composto por instrumentos validados: Mini Exame do Estado Mental - MEEM; HY - Escala de Grau de Incapacidade; Escala Unificada de Avaliação da Doença de Parkinson - UPDRS 1 e valores totais; Questionário sobre a Doença de Parkinson - PDQ-39; Escala de Sono para a Doença de Parkinson - PDSS; Inventário de Depressão de Beck - BDI; Escala de Severidade de Fadiga - FSS e Magnitude das Alterações Percebidas. Resultados: Após doze semanas de intervenção, observou-se que o GE apresentou melhora nos escores de todos os testes. A comparação entre os grupos, no entanto, indicou uma diferença significativa no período pós-UPDRS1 em que o GE apresentou melhora no comprometimento cognitivo, enquanto o GC apresentou déficit nesses valores. Os resultados da divisão entre os subtipos da doença apresentam uma maior mudança nos valores entre os indivíduos do grupo TD ao comparar o GE com o GC. Em relação ao GE, a maior diferença entre a pré e pós-intervenção foi relacionada à fadiga. Conclusão: Houve tendência positiva em todas as variáveis estudadas após a aplicação do protocolo. Isso demonstra que intervenções como a dança podem ter maiores efeitos sobre os sintomas não motores, dependendo da progressão esperada da doença. A escassez de estudos que utilizam essa abordagem em suas análises pode explicar a falta de evidências nessa sintomatologia relacionadas à dança.

Resumo Fundamentos: Novos protocolos aplicados na reabilitação da doença de Parkinson possibilitam diferentes estratégias de atuação para profissionais de saúde, além de um novo leque de atividades para estes indivíduos. Entretanto, não se encontrou na literatura qualquer protocolo de samba com prescrição de atividades validado para esta população. Objetivo: O objetivo foi verificar a viabilidade de um protocolo de samba brasileiro em indivíduos com doença de Parkinson. Métodos: Vinte participantes, com idade média de 66,4±10,7 anos, com diagnóstico de doença de Parkinson idiopática divididos em: grupo experimental que recebeu a intervenção das aulas de dança - samba brasileiro (10 indivíduos); e grupo controle que manteve as suas atividades rotineiras (10 indivíduos). Para a coleta dos dados foi utilizado um questionário dividido: Informações Gerais; Escala de estágios de Incapacidade; Equilíbrio e Qualidade de Vida. Resultados: Durante a realização das aulas, não houve quedas, todas as atividades de dança aderiram aos detalhes das etapas do protocolo, sem quaisquer alterações, e os pacientes completaram, em média, 82,7% das atividades. Após 12 semanas, o grupo experimental apresentou melhoras no escore global da escala UPDRS, em atividades de vida diária e no exame motor. Houve também melhora nos escores de equilíbrio e no domínio de mobilidade da qualidade de vida do grupo experimental. Conclusão: A utilização de um protocolo de samba para indivíduos com doença de Parkinson mostrou-se viável, por sua característica segura e prazerosa, e por apresentar benefícios físicos suficientes para combinação com o tratamento medicamentoso. Houve também benefícios nas relações sociais e como uma possível ferramenta de reabilitação em indivíduos com a doença de Parkinson.

RESUMO

In patients with Parkinson's disease (PD), the ability to perform simultaneous tasks may be impaired. However, there is no consensus as to whether the strategy of use dual task (DT) should be used with PD patients during gait and balance training because DT can increase the risk of falls. Therefore, it is necessary to critically analyze the relevant studies and evaluate the indications for the use of DT and its effects as a therapeutic strategy. The aim of this systematic review was to explore the effects of DT gait and balance training in individuals with PD. A total of 602 studies were found. After applying the eligibility criteria, seven studies were selected (three clinical trials, one uncontrolled clinical trial, and three pilot studies). Despite the poor methodological quality, the studies indicated the use of DT during gait and balance training may be beneficial for people with mild to moderate PD in compare of single-task or no intervention. The use of DT during training presented benefits related to gait (gait speed, step length and cadence) and balance (mediolateral and anteroposterior balance in closed-eyes tests). The current scenario shows that using DT in the training seems not to be harmful and could be part of the rehabilitation of PD patients. Further clinical trials are needed to confirm the findings, and it would be the most importance that these studies stratify individuals with degrees of disease severity to verify the effect of using the DT during training.

RESUMO

Upper limb nerve injuries are common, and their treatment poses a challenge for physicians and surgeons. Experimental models help in minimum exploration of the functional characteristics of peripheral nerve injuries of forelimbs. This study was conducted to characterize the functional recovery (1, 3, 7, 10, 14, and 21 days) after median and ulnar nerve crush in mice and analyze the histological and biochemical markers of nerve regeneration (after 21 days). Sensory-functional impairments appeared after 1 day. The peripheral nerve morphology, the nerve structure, and the density of myelin proteins [myelin protein zero (P0) and peripheral myelin protein 22 (PMP22)] were analyzed after 21 days. Cold allodynia and fine motor coordination recovery occurred on the 10th day, and grip strength recovery was observed on the 14th day after injury. After 21 days, there was partial myelin sheath recovery. PMP22 recovery was complete, whereas P0 recovery was not. Results suggest that there is complete functional recovery even with partial remyelination of median and ulnar nerves in mice.

RESUMO

Aim: The aim of this study was to investigate the effects of adding a cognitive task on the performance of three different motor tasks with different demands, discrete skills, serial skills and continuous skills, by individuals with mild, moderate, and severe idiopathic Parkinson' disease (PD). We also investigate the effect of the cognitive task in the secondary task and the cost of the dual-task. Method: This is a cross-sectional study. Individuals with idiopathic PD were divided in three groups with respect to motor severity (mild, moderate and severe groups). Participants' performances were assessed in single and DT conditions including Sit-to-Stand test (SST), Timed Up and Go (TUG), and 10-meter Walk test (T10W). Cognitive task used was verbal fluency Results: The results show that dual task impact the performance of all primary tasks. DT negatively affects the performance of the motor tasks. And there is a different impact according the severity of the disease, severe ones are more affected than mild and moderate. Conclusion: In conclusion, adding a concurrent cognitive task negatively affected the performance of discrete, serial and continuous motor tasks, and this effect is more noticeable in severe than in mild patients. Under dual-task conditions, patients improved their cognitive task performance for gait and TUG, suggesting a prioritization of the secondary task for these tasks. There was no difference between the costs of the three tasks.Abstract Aim: The aim of this study was to investigate the effects of adding a cognitive task on the performance of three different motor tasks with different demands, discrete skills, serial skills and continuous skills, by individuals with mild, moderate, and severe idiopathic Parkinson' disease (PD).

RESUMO

Assisted-treadmill training, may be helpful in promoting muscle mass preservation after incomplete spinal cord injury (SCI). However, biological mechanism involved in this process is still not fully understood. This study investigated the effects of locomotor treadmill training on muscle trophism mediated by protein kinase B (Akt)/mammalian target of rapamycin (mTOR)/p70 ribosomal protein S6 kinase (p70S6K) in paraplegic rats. Adult female Wistar rats underwent an incomplete thoracic SCI induced by compression using an aneurysm clip. After 7 days, injured animals started a 3-week locomotor treadmill training with body weight-support and manual step help. Soleus trophism was measured by muscle weight and transverse myofiber cross-sectional area (CSA). An enzyme-linked immunosorbent assay (ELISA) and western blot analysis were used to detect brain-derived neurotrophic factor (BDNF), tropomyosin-related kinase B (TrkB), Akt, mTOR and p70S6K in paretic soleus. Trained animals did not show locomotor improved, but present an increase in muscle weight and myofiber CSA. Furthermore, the levels of Akt, p70S6K phosphorylation, mTOR and TrkB receptor were increased by training in soleus. In contrast, muscle BDNF levels were significantly reduced after training. The results suggest locomotor treadmill training partially reverts/prevents soleus muscle hypotrophy in rats with SCI. Furthermore, this study provided the first evidence that morphological muscle changes were caused by Akt/mTOR/p70S6K signaling pathway and TrkB up-regulation, which may increase the sensitivity of muscle, reducing autocrine signaling pathway demand of BDNF for cell growth.

RESUMO

BACKGROUND: The Timed up and go test (TUG), the Five times sit-to-stand test (FTSTS) and the Bed Mobility test (BMT) are widely used in clinical practice for Parkinson Disease (PD). However, no reported studies have evaluated the responsiveness to group physical therapy intervention (GPTI). OBJECTIVE: To verify if TUG, FTSTS and BMT were responsive to GPTI. METHODS: Thirty individuals with PD were assessed prior to and after an 8-week evidence-based GPTI. Paired t test was used to determine statistically significant change pre-and post-intervention. Internal responsiveness (IR) was classified with the standardized response mean (SRM). A 5-point Likert scale assessed self-perceived performance by the subjects after the intervention. Analysis of the receiver operating characteristic (ROC) curve was used to determine the accuracy and cut-off scores for identifying participants who had shown improvement. RESULTS: GPTI was efficient in improving real (p≤0.001) and self-perceived mobility performance in all measures. All tests were responsive to changes: the IR varied from medium to high (SRM = 0.7-1.5); the cut-off point for TUG test was >2.2 s, for FTSTS test was >2.5 s and for BM test >1.4 s. CONCLUSIONS: The TUG, FTSTS and BMT were responsive to the GPTI and accurately detected meaningful clinical changes. Our results provide an important information about the clinical application of these tests in PD individuals.

RESUMO

OBJECTIVE: To investigate the measurement properties of the Timed Up and Go Assessment of Biomechanical Strategies (TUG-ABS) to determine its adequacy for use with individuals with Parkinson's disease. SUBJECTS: Fifty individuals with Parkinson's disease. DESIGN: Diagnostic accuracy. METHODS: The study investigated the following properties: reliability (inter-examiner, intra-examiner, test-retest, internal consistency and minimal detectable change), construct validity, and floor and ceiling effect. RESULTS: Considering the total score, the inter-examiner, test-retest and intra-examiner reliabilities were classified as excellent (0.95 ≤ intra-class correlation coefficient (ICC)≤0.99). The TUG-ABS presented excellent internal consistency (α = 0.98). The minimal detectable change was 3.82 points. The construct validity between the TUG-ABS and the Unified Parkinson's Disease Rating Scale (UPDRS) - part III was classified as moderate (ρ = -0.62). Significant, elevated and positive correlations were obtained between TUG-ABS and the Balance Evaluation System Test (BESTest)-VI (ρ = 0.72) and negative correlations between TUG-ABS and TUG (ρ = -0.78). The discriminant function obtained with the total score of TUG-ABS classified 60% of the individuals correctly with respect to the group (determined by the performance in TUG) to which they belonged. One-way analysis of variance (ANOVA) showed that TUG-ABS discriminated the individuals with Parkinson's disease in all stages according to Hoehn & Yahr. There was a ceiling effect of 22%. CONCLUSION: TUG-ABS presented adequate measurement properties in individuals with Parkinson's disease.
