Resumo

Muitos problemas na interface mão-objeto são decorrentes da falta de parâmetros confiáveis de forças manuais. Diversos estudos que avaliam essa interface apresentam ainda problemas de validade e confiabilidade de seus resultados. Desta forma, este estudo teve por objetivo verificar as variáveis metodológicas que podem influenciar essas abordagens. Pode ser observado que o posicionamento do indivíduo, a escolha do equipamento, os procedimentos de coleta e análise dos dados, dentre outras variáveis, podem influenciar os resultados obtidos. Uma maior padronização dos procedimentos metodológicos pode contribuir expressivamente para o estabelecimento de referências mais confiáveis sobre as forças manuais.
Palavras-chave:forças manuais, metodologia, design ergonômico

Abstract

Many problems in the interface hand-object are derived from the lack of reliable parameters of hand strength. Several studies that evaluate this interface still present problems of validity and reliability of its results. Thus, this study had as a goal to verify the methodological variables that may influence these researches. It can be observed that the positioning of the subject, the choice of the equipment, the data collection and analysis procedures, amongst other variables, can influence the achieved results. A better standardization of the methodological procedures can contribute expressively for the establishment of more reliable references on the hand strength.
Keywords:hand strength, methodology, ergonomic design
