The present study aimed to compare spatial temporal variables between forward (FW) and backward walking (BW) in individuals with hemiparesis. Ten adults with chronic hemiparesis (30.6±25.1 months), mild motor impairment (20-31 points on Fugl-Meyer lower limb test), good balance (score=50±7 in the Berg scale) and independent walking (able to walk 10 meters without aid) were videotaped walking at comfortable speed with reflexive markers placed on lateral malleolus. The variables stride length, duration and speed and stance phase duration were analyzed with a two-way ANOVA: task and lower limb (LL). Stride length was lower (~44cm) in BW than in FW (F(1,18)=130,94; p≤0,001), as well as for stride (F(1,18)=163,78;p≤0,001) and walking speed (t19=10,99;p≤0,001). Stride and stance duration were ~0,18s e ~8%, respectively larger in BW than in FW (F(1,18)=11,98; p=0,003; F(1,18)=32,00; p≤0,001, respectively). Although the stride length in BW was reduced, the fact that the affected LL remained longer in stance in BW compared to FW indicates that the BW might be a relevant parameter in motor rehabilitation.
