The Effects of Trunk Control Ability on Balance, Gait, and Functional Performance Ability in Patients With Stroke

The aim of this study was to investigate correlations of the Trunk Control Test (TCT), Postural Assessment Scale for Stroke (PASS-TC), and Trunk Impairment Scale (TIS) and to compare the TCT, PASS-TC, TIS and its subscales in relation to balance, gait and functional performance ability after stroke. Sixty-two stroke patients attending a rehabilitation program participated in the study. Trunk control was measured with the use of TCT, PASS-TC, TIS balance (Berg Balance scale; BBS), gait ability (10 m walk test), functional performance ability (Timed Up and Go Test; TUG) and the mobility part of the Mdified Barthel index(MBI), Fugl Meyer-Upper/Lower Extremity (FM-U.L/E). The scatter-plot (correlation coefficient) was composed for the total scores of the TCT, PASS-TC, and TIS. The multiple regression analysis was performed to evaluate the impact of trunk control on balance, gait, and functional performance ability. Twenty eight participants (45.2%) and twenty participants (32.3%) obtained the maximum score on the TCT and PASS-TC respectively; no subject reached the maximum score on the Trunk Impairment Scale. There were significant correlations between the TIS and TCT (r=.38, p<.01), showed that the BBS score (β=.420~.862) had slightly more power in predicting trunk control than the FM-U.L/E, TIS-dynamic sitting balance, TUG and the MBI-mobility part. This study clearly indicates that trunk control is still impaired in stroke patients. Measures of trunk control were significantly related with values of balance, gait and functional performance ability. The results imply that management of trunk rehabilitation after stroke should be emphasized.
