Abstract:
Objective:To investigate the effect of four different limbs postures on leg loading and stability of stand-to-sit (StandTS) in hemiplegic stroke patients.Method:30 hemiplegic stroke patients and 30 healthy individuals participated in this study.The duration,mean lower limb loading,and sway of the center of gravity (COG) in mediolateral directions (COGX) were measured during StandTS at four postures.Result:There were no significant differences in duration,mean lower limb loading,and COGX between the two arm positions during StandTS in hemiplegic stroke patients (0.05＜P＜0.1).In hemiplegic stroke patients performing StandTS,there were significant differences in duration,lower limb loading,and COGX between the different foot positions (P＜0.05).When hemiplegic stroke patients placed the paretic foot posterior,the weightbearing asymmetry between lower limbs was greatly improved,compared with the asymmetry when the non-paretic foot was posterior (P＜0.05).Furthermore,when the non-paretic foot was posterior,the duration to complete the StandTS movement increased (P＜0.05),and the postural stability during StandTS improved(P＜0.05).There were no significant differences in duration,mean lower limb loading,and COGX among four different limbs positions during StandTS in healthy individuals (0.05＜P＜0.1).Conclusion:Changing the upper limb position did not affect lower limb loading and postural stability during StandTS in stroke patients.However,changing the foot position significantly influenced the lower limb loading and postural stability during StandTS in hemiplegic stroke patients.
