Abstract:
Objective To investigate the clinical value of a three-dimensional motion analysis system by using the body segmental method for testing the balance of hemiplegic stroke patients.Methods Twenty stroke patients with hemiplegia were measured using the lower extremity Fugl-Meyer motor assessment (FMA-L),the Brunel balance assessment (BBA),the Berg balance sale (BBS) and a 5 m timed up-and-go test (5m-TUGT).The three-dimensional motion analysis system using the body segmental method was applied in three positions-sitting,standing and walking.Spearman's rank correlation coefficient was used to determine the extent of correlation between the values measured by the three-dimensional motion analysis system and the FMA-L,BBA,BBS and 5m-TUGT results.Results Some motion analysis variables (MSAx,MSVx,MSAy,MSVy and SPxy,SP3-D) are recorded in sitting and standing,while the center of gravity (COG) swing in the horizontal plane and some other variables (MSAx,MSVx and SPxy and SP3-D) are measured while walking.Anterior-posterior COG swing had a high negative correlation with the FMA-L,BBA and BBS scores and a high positive correlations with 5m-TUGT times.But except in sitting,MSAz and MSVz were both uncorrelated with FMA-L,BBA or BBS scores or with 5m-TUGT times.COG swing in the horizontal plane in sitting and standing apparently correlates with lower extremity motor function,balance,and walking ability.However,only the X axis swing parameters of the COG while walking correlated with lower extremity motor function,balance or walking ability.Conclusions A three-dimensional motion analysis system using the body segmental method can be used clinically to monitor patients' balance in real time and dynamically in different positions and activities,and it can be used to predict motor function and balance control in hemiplegic stroke patients.
