Were included in the study 32 individuals hemiparetics and 14 healthy as control group. We performed an evaluation of lung function and anthropometric data. The EMGs were performed during the incremental test with Threshold ? (15, 30, 45 and 60% of MIP) and during maximal inspiratory pressure (MIP). The electromyographic findings were calculated by the signal amplitude (RMS). All data were initially analyzed by Kolmogorov-Smirnov, the anthropometric characteristics of both groups were tested with the Levene and then intra-subject analysis (hemiparetic hemithorax and healthy hemithorax) and inter-group analysis (experimental group and control group) by paired and non-paired Student t tests and Pearson correlation. In intra-subject comparison was observed less activation (p <0.01) of the sternocleidomastoid muscle, scalene and diaphragm paretic side in both sexes - for the Threshold ? incremental test (15, 30, 45 and 60% of the MIP) and during maximal inspiratory pressure (MIP). In inter-group comparison, there was reduced activity in the diaphragm and the scalene, in hemiparetics males and females, respectivelly, during the same test. Our results demonstrate the existence of reduced electromyographic activity of inspiratory muscles in hemiparetics, including changes between different genders and suggests the need of further studies to assess the effects of specific training of inspiratory muscles. / O objetivo do estudo foi avaliar atrav?s da eletromiografia de superf?cie a ativa??o dos m?sculos inspirat?rios durante o teste incremental em indiv?duos com sequela decorrente de acidente vascular encef?lico (hemiparesia) e correlacionar com a Medida de independ?ncia Funcional (MIF). Foram inclu?dos no estudo 32 indiv?duos hemipar?ticos e 14 saud?veis como grupo controle. Foi realizada uma avalia??o da fun??o pulmonar e dos dados antropometricos. A EMGs realizou-se durante o teste incremental com Threshold? (15, 30, 45 e 60% da PImax) e durante press?o inspirat?ria m?xima (PImax). Os achados eletromiogr?ficos foram calculados por meio da da amplitude do sinal (RMS). Todos os dados foram inicialmente analisados pelo teste de Kolmogorov-Smirnov, as caracter?sticas antropom?tricas dos dois grupos foram submetidas ao teste de Levene e em seguida realizadas an?lises intra-sujeitos (hemit?rax hemipar?tico e o contralateral) e an?lises inter-grupos (grupo experimental e grupo controle), utilizando os testes t de Student pareado e n?o pareado e correla??o de Pearson. Na compara??o intrasujeitos observou-se menor ativa??o (p<0,01) dos m?sculos esternocleidomastoid?o, escaleno e diafragma do lado par?tico em ambos os sexos durante o teste incremental com Threshold? (15, 30, 45 e 60% da PImax) e durante press?o inspirat?ria m?xima. Na compara??o inter-grupos, houve menor atividade do diafragma em hemipar?ticos e do escaleno em hemipar?ticas durante mesmo teste. Nossos resultados demonstram a exist?ncia de redu??o da atividade eletromiogr?fica dos m?sculos inspirat?rios em hemipar?ticos, apresentando inclusive altera??es distintas entre os sexos e sugere a necessidade de novos estudos que avaliem os efeitos do treinamento espec?ficos dos m?sculos inspirat?rios.
