Purpose: This study aimed to investigate the effects of squat training performed on different support surfaces on lower limb muscle oxygen saturation (SmO2), muscle activity, and walking ability in individuals with chronic stroke. Methods: Thirty participants with chronic stroke were randomly assigned to an experimental group (unstable surface squat training, n = 15) or a control group (stable surface squat training, n = 15). Both groups received conventional physical therapy in addition to squat training three times per week for six weeks. Muscle oxygen saturation of the vastus lateralis and medial gastrocnemius was measured using near-infrared spectroscopy. Muscle activity of the rectus femoris, biceps femoris, and gastrocnemius was assessed using surface electromyography. Walking ability was evaluated using the 6-Minute Walk Test (6MWT). Data were analyzed using a two-way repeated-measures ANOVA. Results: Muscle oxygen saturation showed significant time effects in both the vastus lateralis (p = 0.004) and medial gastrocnemius (p < 0.001), with no significant group × time or interaction effects. Muscle activity demonstrated significant group × time interactions in the rectus femoris (p < 0.001), biceps femoris (p < 0.01), and gastrocnemius (p < 0.05), with the experimental group showing greater improvements. Walking ability also showed a significant group × time interaction (p < 0.05), with significant improvement observed only in the experimental group. Conclusion: Unstable surface squat training appeared more effective than stable surface training in improving neuromuscular activation and walking ability in individuals with chronic stroke. These findings suggest that incorporating unstable support surfaces into rehabilitation programs may enhance functional recovery by promoting neuromuscular adaptations.
