Abstract: Background: Stroke is one of the major causes of mortality and morbidity in the elderly. Treadmill training has been used to improve mobility, balance and walking performance in patients with stroke. Speed-dependent treadmill (SDT) is a new regime of treadmill training. It enabled patients to be trained to walk on treadmill in an interval sprinting training mode by varying the belt speed. It was found to be effective to improve gait and functional performance in patients with chronic stroke. However, the effect of SDT in patients with sub-acute stroke is not known. Objective: This study aimed to compare the effects of SDT and steady-speed treadmill training (SST) in patients with sub-acute stroke, Method: Twenty-eight subjects with stroke at sub-acute stage were randomly assigned to SDT study group (n=15) and control (n=13) Subjects in study group underwent SDT training while those in the control group had steady-speed treadmill training. Prior to and after 10 sessions of training, gait performance (gait speed, stride length and cadence) and balance performance measured by Berg Balance Scale (BBS) were assessed and analyzed. Results: Results of 2-way repeated measure ANOVA showed significant improvements in gait speed (p=0.000), cadence (p=0.000), stride length (p=0.000) and BBS (p=0.000) after the training program within each subject group In addition, SDT group showed a significant higher percentage increases in gait speed (by 78.9%)(p=0.010) and stride length (by 26.0%) (p=0.021) than the control group. Conclusion: Both SDT and SST are effective to improve gait and balance performance in patients with sub-acute stroke. However. SDT achieved more significant percentage improvements in gait speed and stride length when compared with SST. Findings ofthis study showed that SDT has a superior effect in improving gait speed and stride length than SDT in patients with sub-acute stroke.
