The Movement Deviation Profile Can Differentiate Faller and Non-Faller Older Adults.

BACKGROUND: The World Health Organization considers falls the second leading cause of death by accidental injury worldwide and one of the most frequent complications in older adults during activities of daily living. Several tasks related to fall risk have been individually assessed describing kinematic changes in older adults. The study proposal was to identify which functional task differentiates faller and non-faller older adults using the movement deviation profile (MDP). METHODS: This cross-sectional study recruited 68 older adults aged ≥60 years by convenience sampling. Older adults were divided into 2 groups: with and without a history of falls (34 older adults in each group). The MDP analyzed the 3-dimensional angular kinematics data of tasks (ie, gait, walking turn, stair ascent and descent, sit-to-stand, and stand-to-sit), and the Z score of the mean MDP identified which task presented the greatest difference between fallers and non-fallers. A multivariate analysis with Bonferroni post hoc verified the interaction between groups considering angular kinematic data and the cycle time of the task. Statistical significance was set at 5% (p < .05). RESULTS: Z score of the MDPmean showed an interaction between groups (λ = 0.67, F = 5.085, p < .0001). Fallers differed significantly from non-fallers in all tasks and the greatest difference was in stair descent (Z score = 0.89). The time to complete each task was not different between groups. CONCLUSIONS: The MDP distinguished older adult fallers from non-fallers. The stair descent task should be highlighted because it presented the greatest difference between groups.

Translation and cross-cultural adaptation of the Brazilian version of the PM-Scale: A specific measure of participation after stroke.

BACKGROUND: The PM-Scale was developed specifically to assess participation in individuals after stroke based on the concepts contained in the International Classification of Functioning, Disability and Health. However, this measure is only available in English and French. OBJECTIVE: To translate and cross-culturally adapt the PM-Scale to Brazilian Portuguese, followed by the validation and testing of reliability of the translated version. METHODS: The translation process followed standard guidelines. Preliminary test-retest reliability was determined using the intraclass correlation coefficient (ICC2,1). The Rasch model was employed to analyse the validity, unidimensionality, invariance, and internal consistency of the Brazilian version of the PM-Scale. RESULTS: The final translated version of the PM-Scale presented appropriate semantic, idiomatic, cultural, and conceptual equivalence. The preliminary analysis revealed excellent intra-observer and inter-observer reliability (ICC2,1 = 0.91; 95%CI: 0.83, 0.95 and ICC2,1 = 0.81; 95%CI: 0.64, 0.89, respectively). The analysis of the Rasch model revealed only one erratic item. An excellent overall fit was found for items (mean ± SD = 0.01 ± 1.02) and adequate fit was found for persons (mean ± SD = 1.16 ± 0.88). Internal consistency was considered adequate (person separation index = 1.77, reliability = 0.76). No significant invariance was found with regards to the personal characteristics of the sample (p > 0.05). CONCLUSION: The Brazilian version of the PM-Scale is a valid, unidimensional, linear, reliable scale for measuring participation in stroke survivors and can be administered in less than five minutes.

Clinimetric properties of the SATIS-Stroke questionnaire in the Brazilian population: A satisfaction assessment measure addressing activities and participation after a stroke.

BACKGROUND: SATIS-Stroke questionnaire has been translated and adapted for use in the Brazilian population, however, it is necessary to test the measurement properties in Brazilian population. OBJECTIVE: To test the reliability, agreement, concurrent validity, and diagnostic accuracy of the SATIS-Stroke. METHODS: Chronic stroke survivors were included. The calculations were made using scores in logits (Rasch Model). Reliability was tested using the intraclass correlation coefficient (ICC2,1), standard error of measurement (SEM), minimal detectable change (MDC), and Bland-Altman plots. Concurrent validity was analyzed using Spearman's correlation coefficient. For such, the correlation between SATIS-Stroke and Stroke Specific Quality of Life (SS-QOL) questionnaires was determined. Diagnostic accuracy was estimated based on the area under the receiver operating characteristic (ROC) curve with a 95% confidence interval and considering the sensitivity and specificity of SATIS-Stroke in differentiating different types of activity and participation. RESULTS: Eighty stroke survivors were analyzed. Mean age was 57.98±13.85 years and 45.2% had severe impairment. Excellent reliability was found (intra-observer ICC2,1 = 0.90; 95% CI: 0.84, 0.93; inter-observer ICC2,1 = 0.89; 95% CI: 0.83, 0.93). The Bland-Altman plot demonstrated satisfactory agreement. In the analysis of concurrent validity, a strong, positive, significant correlation was found between SATIS-Stroke and SS-QOL (rs = 0.74; p <0.001 with an r2=0.44; p=0.001). Diagnostic accuracy was satisfactory, with 80.8% sensitivity and 85.2% specificity. CONCLUSION: The Brazilian version of the SATIS-Stroke questionnaire exhibited adequate reliability, concurrent validity, and diagnostic accuracy. Therefore, this is a valid, reproducible measure for the assessment of satisfaction with regard to activities and participation following a stroke.

Associação entre a classificação da deambulação funcional com a velocidade da marcha após acidente vascular cerebral / Association between the classification of functional ambulation classification and gait speed after stroke

A escolha do instrumento adequado é decisiva para o sucesso da avaliação funcional e reabilitação. Diante disto, é necessário que o profissional tenha amplo conhecimento dos instrumentos disponíveis para que possa optar pela avaliação mais eficaz, menos onerosa e mais rápida. Objetivo: Analisar se a classificação da deambulação obtida pela Functional Ambulation Classification (FAC) se associa com o desempenho obtido no Teste de Caminhada de 10 metros (TC10M). Métodos: Estudo transversal no qual foram avaliados 61 indivíduos acometidos pelo Acidente Vascular Cerebral (AVC). Utilizou-se o TC10M e a FAC. Para verificar a normalidade dos dados foi utilizado teste Kolmogorov ­ Smirnov. Foi utilizado o ANOVA de uma via para verificar se houve diferença dos deambuladores dependentes e independentes conforme a FAC com a velocidade da marcha por meio do TC10M. Foi realizado um teste post hoc e o método de Scheffe, considerando p≤0,05. Para analisar a associação da categorização da deambulação com a velocidade da marcha, foi o utilizado o teste do qui-quadrado de independência. Resultados: Houve diferença significante de cada nível da FAC em relação a velocidade da marcha. Houve associação entre as classificações obtidas pela FAC e pelo TC10m [x2(9) = 145,335; p=0,001]; sendo que em 48% as variáveis estão corretamente associadas. Conclusão: Os achados indicaram que os níveis da FAC apresentaram associação com a velocidade da marcha.

There was an association between the classifications obtained by the FAC and by the TC10m [x2(9) = 145.335; p= 0.001]; and in 48% the variables are correctly associated. Conclusion: The findings indicated that the FAC levels were associated with walking speed. This finding expands the knowledge about gait assessment measures and helps clinical practice, considering that it facilitates the choice of the best instrument to assess gait after stroke

Translation and Cross-Cultural Adaptation of SATIS-Stroke for Use in Brazil: A Satisfaction Measure of Activities and Participation in Stroke Survivors.

INTRODUCTION: SATIS-Stroke was developed to measure satisfaction regarding activities and participation among stroke survivors based on the concepts contained in the International Classification of Functioning, Disability, and Health. However, this measure is only available in English and French. OBJECTIVE: Perform the translation and cross-cultural adaptation of SATIS-Stroke to Brazilian Portuguese and test the preliminary reliability of this measure. METHODS: The translation process followed standardized guidelines and consisted of six phases: initial translation, back-translation, analysis of expert committee, test of final version, submission, and assessment of all written reports. To test the preliminary test-retest reliability, the measure was administered by a single observer on two occasions with an interval of 7 to 14 days for the determination of intraobserver agreement and administered again by a second observer for the determination of interobserver agreement. Reliability was analyzed using the intraclass correlation coefficient (ICC2,1) and respective 95% confidence intervals (CI). RESULTS: All stages of the cross-cultural adaptation process were respected and the final translated version of SATIS-Stroke exhibited semantic, idiomatic, cultural, and conceptual equivalence to the original version. The preliminary analysis revealed excellent intraobserver and interobserver reliability (ICC = 0.93; 95% CI: 0.83-0.97, p = 0.001 and ICC = 0.90; 95% CI: 0.74-0.96; p = 0.001, respectively). The items demonstrated adequate internal consistency, although ceiling and floor effects were considered beyond acceptable standards for some items. In the exploratory factor analysis, three factors were extracted that aggregated more than one construct to each component, but all were related to the "Activities and Participation" component of the International Classification of Functioning, Disability, and Health. CONCLUSION: The final version of the SATIS-Stroke scale in Brazilian Portuguese proved to be adequate and reliable for use on the Brazilian population. Further studies are underway to give continuity to the validation process and analyze the others measurement properties of the scale in the Brazilian population.
