Background: Patients with chronic stroke often experience postural instability and difficulty in performing sit-to-stand, which can impact their functional independence. The lateral asymmetrical foot placement sit-to-stand method has been shown to enhance muscle activation and weight-bearing on the affected limb, which may be beneficial for rehabilitation. Objective: This pilot study aimed to explore the effects of lateral asymmetrical foot placement sit-to-stand training, compared with normal foot placement, on postural balance, sit-to-stand performance, and weight-bearing in individuals with chronic stroke. Methods: Twenty participants were randomized into the intervention group (n = 10) or the control group (n = 10). The intervention group practiced sit-to-stand with the unaffected foot placed laterally one foot length outward, while the control group used normal shoulder-width foot placement. Training was conducted three times per week for four weeks. Outcome measures included Berg Balance Scale, 5 Times Sit-to-Stand Test, and weight-bearing assessment were measured pre- and post-training. Results: No significant between-group differences were found in any outcomes. Only the intervention group showed a significant improvement on Berg Balance Scale (mean change = 4.20, 95%CI: 1.75, 6.65, p = .001). Conclusion: Lateral asymmetrical foot placement sit-to-stand training did not show superior results compared to normal foot placement. The small sample size is a limitation and should be considered in future.
