Faria Salud stroke Physical therapy reproducibility of results muscle strength dynamometer Background: Muscle strength is usually measured in individuals with stroke with Portable dynamometers (gold standard). However, no studies have investigated the reliability, the standard error of measurement (SEM) and the minimal detectable difference (MDD95%) of the dynamometry for the measurement of hand grip, pinch grip and trunk strength in subjects with subacute stroke. Objective: 1) To investigate the intra and inter-rater reliability, the SEM and the MDD95% of the portable dynamometers for the measurement of grip, pinch and trunk strength in subjects with subacute stroke, and 2) to verify whether the use of different number of trials (first trial and the average of the first two and three trials) affected the results. Method: 32 subjects with subacute stroke (time since stroke onset: 3.6 months, SD=0.66 months) were evaluated. Hand grip, 3 pinch grips (i.e. pulp-to-pulp/palmar/lateral) and 4 trunk muscles (i.e. flexors, extensors, lateral flexors and rotators) strength were bilaterally assessed (except trunk flexors/extensors) with portable dynamometry by two independent examiners over two sessions (1-2 weeks apart). One-way ANOVAs and intraclass correlation coefficients (ICC2,k) were used for analysis (α=0.05). SEM and MDD95% were also calculated. Results: For all muscular groups and sources of outcome values, including one trial, after familiarization, similar results were found (0.01≤F≤0.08; 0.92≤p≤0.99) with significant and adequate values of intra-rater (0.64≤ICC≤0.99; 0.23≤95%CI≤0.99) and inter-rater (0.66≤ICC≤0.99; 0.25≤95%CI≤0.99) reliability. SEM and MDD95% were considered low (0.39≤EPM≤2.21 Kg; 0.96≤MMD95%≤6.12 Kg) for all outcome scores. Conclusion: Only one trial, following familiarization, demonstrated adequate intra-rater and inter-rater reliability of the portable dynamometers for the measurement of hand grip, pinch grip and trunk strength in subjects with subacute stroke. 2016 artículo científico 1413-3555 https://www.redalyc.org/articulo.oa?id=235048333003 en http://www.redalyc.org/revista.oa?id=2350 Revista Brasileira de Fisioterapia application/pdf Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia Revista Brasileira de Fisioterapia (Brasil) Num.5 Vol.20 |
