|Purpose：The purpose of this study was to compare the respiratory function in the different body position of the stroke patients. Methods：Twenty patients with stroke patients group(M:12, F:8) and twenty control group(M:12, F:8) were participated in experiment. Strokes patients group and control group were assessed according to position changes(supine position, 45˚ sitting position, 90˚ sitting position) using pulmonary function(vital capacity, inspiratory capacity, tidal volume, expiratory reserve volume, inspiratory reserve volume). Results：These findings suggest that supine position in stroke group and control group were significant difference in IC, VC, IRV, ERV(p<05). 45˚ lean sitting position in stroke group and control group were significant difference in IC, VC, ERV(p<05). 90 sitting position in stroke group and control group were significant difference in VC, IRV, ERV (p<.05). In comparison of two groups, strokes group was more low pulmonary function than normal group. Conclusion：This study showed pulmonary function was more high normal groups than stroke groups. And 90˚ sitting position was high pulmonary function than supine position, 45˚ lean sitting position, Thus it indicates that the functions will be suggest the objective data of patients with strokes for respiratory function.
