Objective To observe the effects of reinforced trunk and pelvis control training on the motor function of stroke patients. Methods Sixty-two stroke patients were randomly divided into a therapy group and a control group with 31 cases in each group. All were treated with routine medication and regular rehabilitation training.The patients in the therapy group also received trunk and pelvis control training. The Fugl-Meyer assessment scale (FMA) , Barthel index (BI) and functional ambulation categories (FAGs) were used to assess the motor function of the patients before and after treatment. Results After 2 months of treatment there were significant improvements in FMA, BI, FAC and gait in both groups, but the average walking ability in the therapy group was significantly better than that in the control group. Conclusions Reinforced control training of the trunk and pelvis combined with routine rehabilitation improves motor function in hemiplegic stroke patients significantly better than standard rehabilitation alone.
