Reliability and validity of remote Life Space Assessment: LSA in persons with chronic stroke.

BACKGROUND: StepWatch Activity Monitor (SAM) is used to measure the mobility of chronic hemiparetic patients and the Life Space Assessment (LSA) scale was developed to assess the displacement of hemiparetic patients in different contexts through self-reporting. Studies that apply the LSA remotely and correlate it with the number of steps measured by the SAM were not found. OBJECTIVE: To evaluate the measurement properties of the LSA applied remotely and to evaluate the correlation between the LSA scale score and the number of steps measured by the SAM in post-stroke chronic hemiparetic patients. METHODS: Nineteen patients participated in the study. The LSA scale was applied remotely and later, face to face. The SAM measured the steps taken by the participants over a period of three consecutive days. The correlation between the LSA and the SAM was performed using Pearson's correlation. The measurement properties calculated of remote LSA were the intraclass correlation coefficient (ICC), Cronbrach's alpha, standard error of measurement (SEM), and smallest real difference (SRD). RESULTS: The reproducibility of the LSA scale between remote and face-to-face applications was considered excellent with ICC = 0.85 (IC 95% 0.62-0.94); SEM = 8.4; SRD = 23.2, and Cronbach's alpha = 0.85. The correlation between SAM and LSA was positive, considered moderate (r = 0.51) and significant (p = 0.025). CONCLUSION: The LSA is a reproducible measure for post-stroke chronic hemiparetic patients even if applied remotely and can be used as a remote measurement for mobility in a real-world environment for people with chronic hemiparesis after stroke.

ANTECEDENTES: O StepWatch Activity Monitor (SAM) é utilizado para medir a mobilidade de pacientes hemiparéticos crônicos e a escala Life Space Assessment (LSA) avalia o deslocamento de pacientes hemiparéticos em diferentes contextos por meio de autorrelato. Não foram encontrados estudos que tenham aplicado a LSA remotamente nem que a correlacionam com o número de passos mensurados pelo SAM. OBJETIVO: Avaliar as propriedades de medida da LSA aplicada remotamente e avaliar a correlação entre o escore da escala LSA e o número de passos mensurados pelo SAM em pacientes com hemiparesia crônica pós-AVC. MéTODOS: Dezenove participantes responderam a LSA remotamente e, posteriormente, presencialmente. O SAM mediu os passos dados pelos participantes durante um período de três dias consecutivos. A correlação entre a LSA e o SAM foi realizada por meio da correlação de Pearson. As propriedades de medida calculadas da LSA aplicada remotamente foram o coeficiente de correlação intraclasse (ICC), alfa de Cronbrach, erro do padrão de medida (SEM) e menor diferença real (SRD). RESULTADOS: A reprodutibilidade da escala LSA entre as aplicações remotas e presenciais foi considerada excelente com ICC = 0,85 (IC 95% 0,62-0,94); SEM = 8,4; SRD = 23,2 e alfa de Cronbrach = 0,85. A correlação entre SAM e a LSA foi positiva, considerada moderada (r = 0,51) e significativa (p= 0,025). CONCLUSãO: A LSA é uma medida reprodutível para pacientes hemiparéticos crônicos pós-AVC mesmo se aplicada remotamente e pode ser usada como uma medida remota de mobilidade em ambiente real para pessoas com hemiparesia crônica após AVC.

Linking patient reported shoulder outcomes to the international classification of functioning, disability and health.

PURPOSE: To link the items from shoulder-specific Patient Reported Outcome Measures (PROMs) to the International Classification of Functioning, Disability and Health (ICF) domains and categories, and to determine if the items fit into the ICF framework. MATERIALS AND METHODS: The Brazilian versions of the Oxford Shoulder Score (OSS), Shoulder Pain and Disability Index (SPADI), Simple Shoulder Test (SST) and Western Ontario Rotator Cuff Index (WORC) were linked to the ICF by two researchers independently. Agreement between raters was determined by calculating the Kappa Index. RESULTS: Fifty-eight items from the PROMs were linked to eight domains and 27 categories of ICF. The PROMs covered components of body functions, activities, and participation. Components of body structure and environmental factors were not covered by any of the PROMs. ​There was substantial agreement between raters when linking the OSS (Kappa index = 0.66), SPADI (Kappa index = 0.92), SST (Kappa index = 0.72) and WORC (Kappa index = 0.71). CONCLUSIONS: WORC and SST were the PROMs that covered the highest number of ICF domains (seven and six, respectively). However, SST is short and may be less time consuming in a clinical assessment. Clinicians can benefit from this study to decide which shoulder-specific PROM may be more adequate according to the clinical demand.Implications For RehabilitationWestern Ontario Rotator Cuff Index was the shoulder-specific Patient Reported Outcome Measure (PROM) that best showed a broader view of functionality through the International Classification of Functioning, Disability and Health (ICF) domains that can influence shoulder pain and disability.Simple Shoulder Test seems to be the most recommended shoulder-specific PROM considering the number of domains covered by the ICF and the clinical evaluation time consumption.Shoulder Pain and Disability Index fails to provide a broader view of functioning through other ICF domains that may influence shoulder pain and disability.

Shoulder complex and trunk coordination of individuals with severe hemiparesis following a constraint-induced movement therapy protocol: A case series.

INTRODUCTION: Constraint Induced Movement Therapy (CIMT) has been shown to be an effective rehabilitation technique in individuals with mild and moderate upper limb (UL) hemiparesis. The aim was to evaluate the effect the CIMT for improving paretic UL use and interjoint coordination with individuals in severe hemiparesis. METHODS: Six individuals with severe chronic hemiparesis (mean age = 55 ± 16 years) received a UL CIMT intervention for 2 weeks. UL clinical assessments were conducted five times: two assessments at pre-intervention and then, one assessment at post-intervention and 1- and 3-month follow-up using the Graded Motor Activity Log GMAL) and the Graded Wolf Motor Function Test (GWMFT). Scapula, humerus and trunk coordination variability were assessed using the 3-D kinematics during arm elevation, combing hair, turning on the switch and grasp a washcloth. A paired t-test was used to check differences between coordination variability and a one-way ANOVA repeated measures was used to check differences between GMAL and GWMFT scores. RESULTS: There were no differences in GMAL and GWMFT between the patient screening and the baseline data collection (p > 0.05). GMAL scores increased at post-intervention and at follow-ups (p < 0.02). GWMFT performance time score decreased at post-intervention and at 1-month follow-up (p < 0.04). Improvements in kinematic variability of the paretic UL at pre and post-intervention were observed in all tasks, except in the activity of turn on the light switch. CONCLUSION: Following the CIMT protocol, improvements in GMAL and GWMFT scores may reflect improvements in paretic UL performance, in real-life environment. Improvements in kinematic variability may reflect an improving of UL interjoint coordination for individuals with chronic severe hemiparesis.

Self-reported use of the paretic lower extremity of people with stroke: A reliability and validity study of the Lower-Extremity Motor Activity Log (LE-MAL) - Brazil.

BACKGROUND: Most measures to assess the lower extremity (LE) after a neurological injury assess the lower limb motor capacity in the laboratory or clinical settings as the lower-extremity motor subscale of Fugl Meyer Assessment (FMA-LE). The LE Motor Activity Log (LE-MAL) measures the use of paretic LE in real-life conditions, which for many researchers and stakeholders is considered an important goal of rehabilitation. OBJECTIVE: Investigate the reliability, validity, floor, and ceiling effects of the Brazilian version of the LE-MAL. METHODS: Cross-sectional study to examine the reliability and validity of LE-MAL in patients with chronic stroke. The translation and adaptation of LE-MAL was carried out for the Brazilian version. After this stage, to ensure the inter-rater reliability two raters (LCF, DBM) applied the translated version of LE-MAL in the 21 selected participants. Subsequently, the concurrent validity was calculated by the correlation with the FMA-LE. RESULTS: The translation and retro-translation of the LE-MAL was approved to the Brazilian context. A floor effect was not observed, and there was no ceiling effect for the LE-MAL total scores. The Inter-rater reliability ranged between 0.80 and 0.86. The Bland-Altman analysis showed difference of LE-MAL scores ranged from 0.8 to 1.6. The Cronbach's alpha coefficients for LE-MAL and subscales were high ranging between 0.86 and 0.80. There was a significant moderate correlation between the LE-MAL and FMA-LE (Pearson correlation 0.55 (p = .009)). CONCLUSION: The Brazilian version LE-MAL is valid and reliable to assess real-world use of the paretic LE of individuals with chronic stroke.

Self-management strategies and multicomponent training to mitigate the effects of the interruption of physical exercise programmes in the pandemic context on functionality, sedentary behaviour, physical capacity, mental health, body composition and quality of life in older adults: a blinded randomized controlled study protocol.

BACKGROUND: Considering the confinement recommended by the World Health Organization due to the pandemic caused by COVID-19, many community physical exercise programmes for older adults have had their activities cancelled. In this context, proposing strategies to recover the possible adverse effects of the confinement period is pertinent. The use of self-management strategies associated with regular physical activity reduces sedentary behaviour and improves physical capacity in older adults. Thus, the purpose of this study was to describe a multicomponent training programme combined with a self-management strategy protocol to mitigate the effects of interruptions in physical exercise programmes on functionality, physical capacity, mental health, body composition and quality of life in older adults. METHODS: This will be a blinded, randomized and controlled clinical trial performed in São Carlos, SP, Brazil. Eighty older adults will be divided into two groups: multicomponent training (Multi) and multicomponent training + self-management strategies (Multi+SM). The intervention will be performed over 16 weeks on three alternate days of every week, with 50-min sessions. The assessment of physical capacity will be performed before the interruption of physical exercise programmes (T0: initial assessment, March 2020), preintervention (T1: immediately after the return of the exercise programme) and postintervention (T2). The assessments of physical activity level, quality of life, mental health, functionality and body composition will be performed at T1 and T2. DISCUSSION: The results from this MC+SM protocol will allow us to contribute clinical support to evaluate the variables analysed and to guide future public health policies with the aim of minimizing the possible deleterious effects arising from the physical exercise interruption periods caused by epidemics and pandemics.

Effect of first dorsal interosseous strengthening on clinical outcomes in patients with thumb osteoarthritis: a study protocol for a randomized controlled clinical trial.

BACKGROUND: Thumb carpometacarpal osteoarthritis (CMC OA) is characterized by chronic progressive degeneration of the joint cartilage, with high prevalence. Patients present with pain at the base of the thumb, morning stiffness, and muscle weakness, symptoms that affect hand function and therefore interfere in activities and social participation. Movements that involve grip or lateral pinch are the most affected and directly impact independence, self-care, and leisure activities. In the literature consulted, several protocols with exercises for these patients were found. However, most do not compare the same intervention modality and only provide basic methodological information, with no consistent information on training load and load progression. In addition, most protocols only address the strengthening of the abductor and extensor thumb muscles and pinching or grasping exercises. However, some biomechanical and electromyographic studies have demonstrated the important role of the first dorsal interosseous muscles as stabilizers of the thumb carpometacarpal joint. METHODS: This is a randomized, controlled, double-blind, and parallel clinical trial that will include 56 participants, over 40 years old, with radiographic evidence of thumb base osteoarthritis. Participants will be randomly allocated into two groups: control and intervention. The following evaluations will be conducted: the Australian/Canadian Hand Osteoarthritis Index, Canadian Occupational Performance Measure, Nine-Hole Peg Test, grip and pinch strength associated with muscle activation assessment, and Bilateral Upper Limb Function Test at four different times: baseline, session 13, session 18, and follow-up. Treatment will take place over 6 weeks, with reassessments in the fourth and sixth weeks and 3 months after the end of the intervention (follow-up). Qualitative variables will be expressed as frequency and percentage, and quantitative variables as mean and standard deviation. Intergroup comparison of the intervention will be performed by repeated measures ANOVA, considering the effect of the two groups and four assessments, and interactions between them. DISCUSSION: This study will demonstrate whether the specific strengthening of the first dorsal interosseous muscle has a superior and positive effect on the clinical picture of patients with CMC OA. Additionally, if specific strengthening of the muscle is not superior to the traditional protocol in the literature, it will also be determined whether the two protocols are equivalent in terms of the best clinical picture.

Ratio between 3D glenohumeral and scapulothoracic motions in individuals without shoulder pain.

This study determined the ratio between glenohumeral and three-dimensional scapular motion during arm elevation and lowering in 91 individuals without shoulder pain. Scapular kinematics were assessed using an electromagnetic tracking device. Individuals performed 3 repetitions of elevation and lowering of the arm in the sagittal plane. Two-way ANOVAs (interval: 30-60°, 60-90°, 90-120° x phase: elevation and lowering) and paired t-tests were used for data analysis. For scapular internal/external rotation, lesser scapular internal rotation contribution was found during the 60-90° interval as compared to the 90-60° interval. Lesser scapular external rotation was identified in the 60-30° interval of arm lowering. The ratio was greater during arm elevation (1.89) compared to lowering (1.74) across the entire motion arc. For scapular upward rotation, greater upward rotation contribution was observed during arm elevation at the 30-60° interval, and less scapular downward rotation contribution in the final range of arm lowering. For scapular tilt, lesser scapular posterior tilt contribution during arm elevation was observed compared to arm lowering. The ratios between glenohumeral elevation/lowering and each individual scapulothoracic motion showed either differences between intervals and/or between elevation and lowering during specific intervals in healthy individuals.

Reproducibility of Assessment Tests Addressing Body Structure and Function and Activity in Older Adults With Dementia: A Systematic Review.

OBJECTIVE: The purpose of this study was to analyze the relative and absolute reliability of assessment tests addressing body structure and function and activity in older adults with dementia. METHODS: Medline, Embase, Web of Science, The Cochrane Library, and Scielo were searched from inception until March 2021. Two independent reviewers performed the selection process based on titles, abstracts, and full text. Reliability studies of assessment tests in older adults with dementia were included. Methodological quality of the studies was evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments Risk of Bias checklist. Relative reliability was analyzed using the intraclass correlation coefficient (ICC) interpreted based on Munro classification. Absolute reliability was analyzed using the minimal detectable change (MDC) and standard error of measurement. RESULTS: Fifteen studies involving a total of 560 older adults with dementia were included. Nineteen assessment tests were identified: 13 addressing body structure and function (muscle strength, postural balance, cardiorespiratory fitness) and 6 addressing activity (walking and mobility). Studies determined test-retest and interrater reliability. Fifteen studies evaluated relative reliability using the ICC, with values ranging from no or small correlation to very high correlations. Ten studies evaluated absolute reliability using the MDC or standard error of measurement or both. CONCLUSION: Relative reliability of the assessment tests for body structure and function and activity was high to very high based on ICCs, demonstrating good reproducibility. Regarding absolute reliability, the analysis of the MDC values revealed the need for substantial change to determine that a real change had occurred. Future investigations should consider the type of dementia and standardization of verbal encouragement during the assessment. IMPACT: This review identified the good reproducibility of assessment tests of body structure and function (muscle strength, postural balance, cardiorespiratory fitness) and activity (walking and mobility) domains in older adults with dementia. Clinically important values may differ when older adults with dementia of diverse etiologies are analyzed together and older adults specifically with Alzheimer disease. Identifying the type of dementia, analyzing types of dementia separately, and standardizing verbal commands during the execution of tests is of considerable clinical importance for this population of older adults.

Effect of Resistance Exercise on Body Structure and Function, Activity, and Participation in Individuals With Parkinson Disease: A Systematic Review.

OBJECTIVE: To investigate the effects of resistance exercise (RE) on body structure and function, activity, and participation in individuals with Parkinson Disease (PD) in the mild to moderate stages. DATA SOURCES: Medline, Embase, Web of Science, The Cochrane Library, Lilacs, and PEDro were searched from inception until June 2020 using the terms "Parkinson Disease," "Exercise," "Resistance Training," "Muscle Strength," "Cardiorespiratory Fitness," "Postural Balance," "Gait," and "Quality of Life." STUDY SELECTION: We included studies conducted in individuals with PD involving RE compared with a control group. Two independent reviewers performed the selection process based on titles, abstracts, and full-text reading. In total, 270 individuals with PD were included from 10 selected studies. DATA EXTRACTION: Two reviewers independently extracted characteristics related to participants, intervention and control types, and results. The PEDro scale was used to assess the methodological quality, and the level of evidence was analyzed and synthesized using the Grading of Recommendation, Assessment, Development, and Evaluations approach. DATA SYNTHESIS: The level of evidence for body structure and function was low and without effect for lower limb muscle strength; very low and with effect for upper limb muscle strength, cardiorespiratory fitness, and postural balance; and very low and without effect for flexibility after RE training. For activity, the evidence was very low and with effect for gait and very low and without effect for mobility. For participation (ie, quality of life) the evidence was very low and without effect. CONCLUSIONS: Although the level of evidence was low to very low, RE was shown to promote improvements in body structure and function (upper limb muscle strength, cardiovascular function, postural balance) and activity (gait). In contrast, RE did not significantly improve participation (quality of life). However, based on the present findings, the practice of RE can be recommended for individuals with PD in the mild to moderate stages.

The Effect of Priming on Outcomes of Task-Oriented Training for the Upper Extremity in Chronic Stroke: A Systematic Review and Meta-analysis.

Background. Priming results in a type of implicit memory that prepares the brain for a more plastic response, thereby changing behavior. New evidence in neurorehabilitation points to the use of priming interventions to optimize functional gains of the upper extremity in poststroke individuals. Objective. To determine the effects of priming on task-oriented training on upper extremity outcomes (body function and activity) in chronic stroke. Methods. The PubMed, CINAHL, Web of Science, EMBASE, and PEDro databases were searched in October 2019. Outcome data were pooled into categories of measures considering the International Classification Functional (ICF) classifications of body function and activity. Means and standard deviations for each group were used to determine group effect sizes by calculating mean differences (MDs) and 95% confidence intervals via a fixed effects model. Heterogeneity among the included studies for each factor evaluated was measured using the I2 statistic. Results. Thirty-six studies with 814 patients undergoing various types of task-oriented training were included in the analysis. Of these studies, 17 were associated with stimulation priming, 12 with sensory priming, 4 with movement priming, and 3 with action observation priming. Stimulation priming showed moderate-quality evidence of body function. Only the Wolf Motor Function Test (time) in the activity domain showed low-quality evidence. However, gains in motor function and in use of extremity members were measured by the Fugl-Meyer Assessment (UE-FMA). Regarding sensory priming, we found moderate-quality evidence and effect size for UE-FMA, corresponding to the body function domain (MD 4.77, 95% CI 3.25-6.29, Z = 6.15, P < .0001), and for the Action Research Arm Test, corresponding to the activity domain (MD 7.47, 95% CI 4.52-10.42, Z = 4.96, P < .0001). Despite the low-quality evidence, we found an effect size (MD 8.64, 95% CI 10.85-16.43, Z = 2.17, P = .003) in movement priming. Evidence for action observation priming was inconclusive. Conclusion. Combining priming and task-oriented training for the upper extremities of chronic stroke patients can be a promising intervention strategy. Studies that identify which priming techniques combined with task-oriented training for upper extremity function in chronic stroke yield effective outcomes in each ICF domain are needed and may be beneficial for the recovery of upper extremities poststroke.

Comparison of scapular kinematics and muscle strength between those with a positive and a negative Scapular Assistance Test.

BACKGROUND: The Scapular Assistance Test was suggested to directly assess the influence of scapular motion on pain and indirectly measure the function of the scapular rotators. However, it is still not clear if individuals with a positive Scapular Assistance Test actually present changes in scapular motion and muscle strength. This study compared scapular kinematics and muscle strength between those with a positive Scapular Assistance Test and those with a negative Scapular Assistance Test. METHODS: Fifty individuals with shoulder pain were randomly allocated to: positive (n = 25) or negative Scapular Assistance Test (n = 25) group. Scapular kinematics was measured during elevation and lowering of the arm. Strength of the serratus anterior and lower trapezius was also measured. Two-way analysis of variance was used to compare kinematics between groups. Unpaired Student's t-test and Mann-Whitney test were used to compare strength of serratus anterior and lower trapezius, respectively. FINDINGS: There were no differences (P > 0.05) in scapular internal rotation and upward rotation between both groups. For scapular tilt, there was group main effect (P < 0.05) during elevation and lowering of the arm, whereas the positive Scapular Assistance Test group presented greater scapular anterior tilt. There was no difference (P > 0.05) in strength between groups. INTERPRETATION: Individuals with a positive Scapular Assistance Test are more likely to present decreased scapular posterior tilt in those with shoulder pain. Strength of the scapular muscles seems to be same in those with a positive and a negative Scapular Assistance Test.

The evaluation of non-use of the upper limb in chronic hemiparesis is influenced by the level of motor impairment and difficulty of the activities-proposal of a new version of the Motor Activity Log.

This study aims to evaluate the influence of the degree of difficulty of the activities in Motor Activity Log (MAL) scores for patients with mild, moderate, and severe hemiparesis, and to estimate the correlation between motor impairment levels of hemiparesis and MAL scores in post-stroke patients. Sixty-six patients with chronic hemiparesis (49 with mild-moderate hemiparesis, and 17 with severe hemiparesis) were evaluated by the Fugl-Meyer upper-limb section and versions of MAL for different degrees of motor impairment. The Rasch model was used to analyze the level of difficulty of the activities of the different versions of MAL. The Spearman's correlation tested the relationship between the Fugl-Meyer Assessment upper-limb section and MAL. The MAL version, developed to evaluate patients with severe hemiparesis, does not contain the easier activities as employed by the Rasch analysis. There was positive correlation between the Fugl-Meyer Assessment upper-limb section scores and Amount of Use of the three versions of the MAL (r = 0.76, 0.78, and 0.77). The difficulty of the activities seems to influence the quantity and quality of use of the affected upper limb in individuals with chronic hemiparesis. A new version of MAL is proposed for individuals with severe motor impairment.

Translation, and interobserver and test-retest reliability of the Brazilian Portuguese version of Children's Hospital Oakland Hip Evaluation Scale for patients with sickle cell disease

ABSTRACT Background: The Children's Hospital Oakland Hip Evaluation Scale is a disease-specific tool for the clinical and functional assessment of the hip in sickle cell disease. Objectives: To translate the tool into Brazilian Portuguese and evaluate the interobserver and test-retest reliability. Methods: Eighteen patients diagnosed with sickle cell disease and a mean age of 49 ± 11.9 years participated in the study. The scale was applied by two evaluators who did not speak to each other regarding their understanding of the tool and who had no prior training. Interobserver and test-retest reliability of individual items and of the total score were evaluated using the intraclass correlation coefficient and the Bland-Altman method. Results: When the overall score for each hip was considered, the test-retest intraclass correlation coefficient score for the right hip was 0.95 (0.89-0.98) and for the left hip it was 0.96 (0.91-0.98). Considering all assignments (total score), the score was 0.96 (0.90-0.98). The test-retest intraclass correlation coefficient varied from 0.76 to 1 for 18 of the 27 items (excellent) and from 0.53 to 0.75 for nine items (moderate). When the overall score for each hip was considered, the interobserver intraclass correlation coefficient for both hips was 0.94 (0.86-0.98). Considering all assignments, the total score was 0.94 (0.86-0.98). The interobserver intraclass correlation coefficient varied from 0.48 to 0.75 for 18 out of 27 items (moderate) and varied from 0.77 to 1 for the remaining nine items (excellent). Conclusion: The results demonstrate that the Brazilian version of the Children's Hospital Oakland Hip Evaluation Scale presented adequate interobserver and test-retest reliability and that the version can be used to evaluate clinical function in sickle cell disease patients, producing consistent, standardized and reproducible results.

Translation, cultural adaptation and reliability of the brazilian version of the Graded Wolf Motor Function Test in adults with severe hemiparesis / Tradução, adaptação cultural e confiabilidade da versão brasileira do Graded Wolf Motor Function Test em adultos com hemiparesia grave

Abstract Introduction : The Graded Wolf Motor Function Test (GWMFT) was developed as a modification of the Wolf Motor Function Test (WMFT), designed to address moderate-to-severe upper-extremity motor impairment, consequent to a stroke or brain injury, by combining time and quality of movement measures in both isolated movements and functional tasks. Objectives : To translate and adapt the GWMFT form and instructions manual to Brazilian Portuguese and evaluate the inter-rater reliability. Materials and methods : Ten individuals, mean age 53.2 ± 11.39 (range: 28-72) years and a mean time since stroke onset of 82.5 ± 85.83 (16-288) months participated in the study. After translation and cultural adaptation, two independent evaluators, based on the instructions manual information, administered GWMFT. Video observations were used to rate the time and the compensatory movements in the Functional Ability Scale (FAS). Intra-class Correlation Coefficients (ICCs) and Bland-Altman plots were calculated to examine the inter-rater reliability for performance time and FAS. Results : The translated and adapted version obtained a total ICC inter-rater time 0.99 (0.95-1.00), showing less reliability in the task of lifting a pen, with ICC = 0.71 (- 0.15-0.93). The ICC of the total FAS was 0.98 (0.92-0.99) and the task of elbow extension has shown the lowest ICC rate = 0.83 (0.31-0.96). Conclusion : The GWMFT scale reliability proved to be appropriate to evaluate the paretic upper limb in individuals with chronic hemiparesis post severe stroke.

Resumo Introdução : O Graded Wolf Motor Function Test (GWMFT) foi desenvolvido por meio de uma modificação do Wolf Motor Function Test (WMFT) para avaliar o membro superior de adultos com hemiparesia grave combinando medidas de tempo e qualidade de movimento em movimentos isolados e tarefas funcionais. Objetivos : Traduzir e adaptar para a língua portuguesa o formulário e o manual de aplicação do GWMFT e avaliar a confiabilidade interavaliadores. Materiais e Métodos : Participaram do estudo 10 indivíduos com média de idade 53,2 ± 11,39 (28-72) anos que apresentavam hemiparesia grave (Fugl-Meyer ≤ 30) com cronicidade de 82,5 ± 85,83 (16-288) meses, função cognitiva preservada e ausência de dupla hemiparesia. Após a tradução e adaptação cultural da escala, o GWMFT foi aplicado por dois avaliadores utilizando as informações do manual de aplicação e a filmagem das tarefas foi utilizada para cotar o tempo e qualidade de movimento pela Escala de Habilidade Funcional adaptada (EHF). A confiabilidade interavaliador do tempo e EHF do movimento foram avaliadas pelo Coeficiente de Correlação Intraclasse (CCI) e pelo método Bland-Altman. Resultados : Com a aplicação da versão traduzida e adaptada obteve-se CCI interavaliador total do tempo de 0,99 (0,95-1,00), apresentando menor confiabilidade na tarefa de levantar caneta, com CCI de 0,71 (- 0,15-0,93). O CCI da EHF total foi de 0,98 (0,92-0,99) sendo a tarefa extensão do cotovelo com menor índice de CCI = 0,83 (0,31-0,96). Conclusão : A confiabilidade da escala GWMFT demonstrou-se adequada para avaliar o membro superior parético com acometimento grave em indivíduos com hemiparesia crônica pós AVC.

Frequência cardíaca e percepção subjetiva de esforço durante o andar para trás em velocidade confortável e máxima em adultos com hemiparesia / Heart rate and subjective perception of exertion during backward walking at comfortable and maximal speed in adults with hemiparesis / Frecuencia cardíaca y percepción subjetiva de esfuerzo durante el andar para atrás en velocidades confortable y máxima en adultos con hemiparesia

INTRODUÇÃO E OBJETIVO: Estudos sobre o andar para trás (AT) em indivíduos saudáveis demonstraram que esse exercício demanda maior consumo de oxigênio e esforço cardiopulmonar comparado ao andar para frente (AF). Em indivíduos após acidente vascular encefálico (AVE), o AT demonstrou ser uma forma de terapia benéfica para melhorar parâmetros de marcha. Este estudo teve como objetivo comparar as variáveis frequência cardíaca (FC) e percepção subjetiva de esforço (PSE) entre o AF e AT em esteira rolante em duas velocidades distintas em indivíduos com hemiparesia, algo que poderá contribuir para a definição da melhor estratégia para colocar os indivíduos na zona-alvo de um exercício visando ao aprimoramento das condições cardiorrespiratórias. MÉTODOS: Participaram 13 indivíduos adultos de ambos os sexos (53,7 ± 13,5 anos) com sequela de AVE crônica (38,5 ± 31,2 meses de acometimento). Os indivíduos realizaram a tarefa de AT na esteira em velocidade confortável e máxima, repetindo os procedimentos em velocidades idênticas durante o AF. Foi utilizada uma ANOVA fatorial para testar o efeito do sentido (AF e AT) e da velocidade (confortável e máxima) sobre a FC e PSE. RESULTADOS: A FC foi maior durante o AT nas duas velocidades, sendo essa incrementada com o aumento da velocidade (p < 0,01 para todas comparações). Da mesma forma, a PSE foi maior durante o AT nas duas velocidades, sendo incrementada com o aumento da velocidade (p < 0,01 para todas as comparações). CONCLUSÃO: Andar para trás é uma atividade física mais intensa que andar para frente em uma mesma velocidade para indivíduos com hemiparesia. Os achados sugerem que esta atividade poderia ser uma alternativa na realização de programas com ênfase no condicionamento cardiopulmonar e como complemento de outros procedimentos na reeducação do andar após AVE.

BACKGROUND AND PURPOSE: Backward walking (BW) studies in healthy subjects have demonstrated that this exercise requires more oxygen consumption and cardiopulmonary effort compared to forward walking (FW). In patients after stroke, BW has proven to be a beneficial form of therapy to improve gait parameters. The purpose of this study was to determine whether there are differences in heart rate (HR) and perceived exertion (PE) between FW and BW on a treadmill at two different speeds in individuals with hemiparesis. This may help to define the best strategy to put individuals in the target zone of an exercise aimed at improving cardiorespiratory conditions. METHODS: Participated in the study 13 male and female adults (53.7±13.5 years) with chronic sequelae of stroke (38.5±31.2 months of onset). The subjects performed BW task on the treadmill at comfortable speed and maximum speed and repeated the procedures during the FW at identical speeds. A two-way ANOVA was used to test the effect of directional orientation (BW and FW) and speed (comfortable and maximum) on HR and PE. RESULTS: The HR was greater for the BW in both speeds, and has increased with increasing speed (p < 0.01 for all comparisons). Similarly, the PE was higher in BW compared to FW in both speeds, and has increased with increasing speed (p < 0.01 for all comparisons). CONCLUSION: Walking backwards is a physical activity more intense than walking forward at the same speed for individuals with hemiparesis. This finding suggests that this activity could be used as an alternative method with emphasis on cardiopulmonary fitness and as a complement to other procedures in the rehabilitation of gait after stroke.

INTRODUCCIÓN Y OBJETIVO: Los estudios sobre el andar para atrás (AT), en individuos sanos, demostraron que ese ejercicio demanda más consumo de oxígeno y esfuerzo cardiopulmonar en comparación con el andar hacia adelante (AD). En personas, después de accidente vascular encefálico (AVE), el AT demostró ser una forma de terapia benéfica para mejorar parámetros de marcha. Este estudio tuvo como objetivo comparar las variables frecuencia cardíaca (FC) y percepción subjetiva de esfuerzo (PSE) entre el AD y el AT, en estera rodante, en dos velocidades diferentes en individuos con hemiparesia, algo que podrá contribuir para la determinación de la mejor estrategia a fin de colocar a los individuos en la zona-meta de un ejercicio dirigido a perfeccionar las condiciones cardiorrespiratorias. MÉTODOS: Participaron 13 individuos adultos de ambos sexos (53,7 ± 13,5 años) con secuela de AVE crónica (38,5 ± 31,2 meses de acometimiento). Estas personas hicieron la tarea de AT en la estera, en velocidades confortable y máxima, repitiendo los procedimientos en velocidades idénticas durante el AD. Se utilizó una ANOVA factorial para comprobar el efecto del sentido (AD y AT) y de la velocidad (confortable y máxima) sobre la FC y la PSE. RESULTADOS: La FC fue mayor durante el AT en las dos velocidades, siendo esta incrementada con el aumento de la velocidad (p < 0,01 para todas las comparaciones). De la misma forma, la PSE fue más alta durante el AT en las dos velocidades, siendo incrementada con el aumento de la velocidad (p < 0,01 para todas las comparaciones). CONCLUSIÓN: Andar para atrás es una actividad física más intensa que andar para adelante en una misma velocidad para individuos con hemiparesia. Los hallazgos sugieren que esta actividad podría ser una alternativa en la realización de programas con énfasis en el condicionamiento cardiopulmonar y como complemento de otros procedimientos en la reeducación del andar después de AVE.

Terapia por Contensão Induzida (TCI) em adolescentes com hemiparesia espástica: relato de caso / Constraint Induced-Movement Therapy (CIMT) in adolescents with spastic hemiparesis: a case report

INTRODUÇÃO: A Terapia por Contensão Induzida (TCI) é um protocolo terapêutico que visa diminuir a assimetria de uso dos membros superiores. OBJETIVO: Verificar o efeito da TCI em dois adolescentes, com paralisia cerebral hemiparética (PCH). MATERIAIS E MÉTODOS: Dois adolescentes com PCH, de 12 e 14 anos de idade, receberam aplicação de TCI por três horas diárias durante três semanas. Este estudo apresentou desenho ABA experimental, com um mês de seguimento. Os adolescentes foram avaliados com a Teenager Motor Activity Log (TMAL) e o Wolf Motor Function Test (WMFT); o avaliador esteve independente da intervenção e cegado quanto à ordem das avaliações. RESULTADOS: Houve melhora na quantidade, qualidade e espontaneidade de uso após a aplicação da TCI segundo a escala da TMAL. Os dois pacientes apresentaram diminuição no tempo de execução das tarefas do WMFT e foi observada também melhora na habilidade funcional. CONCLUSÃO: Este estudo mostra efeitos positivos da TCI em adolescentes com PCH. Ressalta-se, no entanto, que se fazem necessários ensaios clínicos para confirmar a eficácia da intervenção nessa população.

INTRODUCTION: The Constraint Induced Movement Therapy (CIMT) is a therapeutic protocol proposed as an attempt to overcome the learned nonuse. OBJECTIVE: To assess constraint induced movement therapy protocol effects on two adolescents with hemiparetic cerebral palsy (HCP). MATERIALS AND METHODS: Two adolescents with HCP aged 12 and 14 years old were included and submitted to a CIMT protocol of three hours/day for three weeks. This study presented an ABA experimental design with a month follow-up. Teenager Motor Activity Log (TMAL) and Wolf Motor Function Test (WMFT) were used for adolescents' data assessment and the evaluator did not participate on the intervention and was blinded considering evaluation order. RESULTS: There have been improvements in quality, amount and spontaneity of use of the affected upper extremity following CIMT with basis on TMAL. Both patients presented a decrease in time spent to perform WMFT tasks and functional skill improvement was observed. CONCLUSION: This study has shown positive effects CIMT on adolescents with HCP. However, further studies are necessary to confirm the intervention's efficacy in this clinical population.

Motor Activity Log-Brazil: reliability and relationships with motor impairments in individuals with chronic stroke.

UNLABELLED: The Motor Activity Log (MAL) assesses the spontaneous use of the most affected upper limb with the amount of use (AOU) and quality of movement (QOM) scales during daily activities in real environments in individuals with chronic stroke. OBJECTIVES: This study translated the testing manual into Portuguese and assessed the inter-rater and test-retest reliabilities of the MAL, based upon the Brazilian manual version. METHODS: The inter-rater reliability was evaluated by comparing the results of two examiners, and the test-retest reliability was tested by comparing the results of two evaluations, repeated one-week apart with 30 individuals with chronic hemiparesis (55.8±15.1 years). RESULTS: The intra-class correlation coefficients (ICCs) for the total scores were adequate for both the inter-rater (0.98 for the AOU and 0.91 for QOM) and test-retest reliabilities (0.99 for both scales). CONCLUSIONS: The results suggested that the MAL was reliable to evaluate the spontaneous use of the most affected upper limb after stroke.
