Objective To explore the effects of partial body weight support treadmill training (PBWSTT) on motor function of lower extremities, walking ability and activities of daily living (ADL) in chronic hemiplegic patients after stroke. Methods28 patients with stable stroke (hemiplegic limbs Brunstrom s' scale≥Ⅲ) exceed 12 months after the onset were divided into PBWSTT group (n=14) and control group (n=14) randomly. Routine rehabilitation were used in the control group, and the PBWSTT group received PBWSTT in addition. They were assessed with Ashworth Spasticity Scale （ASS）, Functional Ambulation Category (FAC), Fugl-Meyer Assessment (FMA), and the Functional Independence Measurement (FIM) before and 8 weeks after the treatment. ResultsThe ASS,FAC, FMA and FIM scores were all improved after treatment in both groups (P<0.05). The scores of FMA, FAC and FIM in the PBWSTT group after treatment exceeded that of control group (P<0.05), but there was no difference in the ASS (P>0.05). ConclusionPBWSTT may improve the motor function of lower extremities, walking ability, and ADL in chronic hemiplegic patients after stroke.
