“…While these findings are similar to previous research reporting intra-test ICC values for mean RMS and frequency during single-joint isokinetic tests (Larsson et al, 1999a;Larsson et al, 1999b), these previous investigations have demonstrated a smaller range of ICC values than the current study. While this may indicate greater variability in the current study, caution should be taken when comparing ICC values between separate investigations, as this statistic is largely influenced by the range of data scores and the population studied (Atkinson and Nevill, 1998).…”

“…At present, it is difficult to determine the cause of the varied reliability within certain sets, as no clear relationships are evident between the level of reliability and either the number of repetitions performed in a set, nor the intensity of the set. It is possible that the small sample size employed, although similar to previous investigations that have assessed EMG reliability (Larsson et al, 1999a;Larsson et al, 1999b), may have contributed to these findings.…”

“…O conhecimento da reprodutibilidade e do erro típico 21 associado à medida da atividade EMG é crucial para a interpretação dos resultados das investigações e esta tem sido estudada principalmente em ensaios envolvendo contrações isométricas 14,22 , usando equipamento isocinético de alto custo 22 , porém, pouco investigada em tarefas dinâmicas, mais próximas de atividades cotidianas do dia a dia. Para mensurações da reprodutibilidade, o coeficiente de correlação intraclasse (CCI) é preferível ao coeficiente de correlação de Pearson (r).…”

“…Para mensurações da reprodutibilidade, o coeficiente de correlação intraclasse (CCI) é preferível ao coeficiente de correlação de Pearson (r). O último não é sensível a fatores como mudanças na média e no desvio padrão que tendem a superestimar a reprodutibilidade 14,22 . O entendimento do comportamento neuromuscular e dos erros associados a esta medida, em atividades ocupacionais e dinâmicas, possibilita o desenvolvimento de melhores métodos de avaliação e tratamento das disfunções neuromusculares 5,6 .…”
