| Introduction: Visual impairment restricts sensory input, leading to significant gait alterations, including reduced step length and increased step width. This study investigated the effects of an eight-week Suspension Training (TRX) program on these gait parameters in individuals with visual impairment. Methods: Twenty young adults with visual impairment were randomly allocated into two groups: a TRX training group (n=10) and a control group (n=10). The intervention group underwent supervised TRX sessions three times per week for eight weeks (50-60 minutes per session). The training protocol consisted of a warm-up (8-10 minutes), a main exercise component (comprising six functional TRX exercises: Squat-Row, Single-Leg Sit-Up, Hamstring Curl, Chest Press, Pallof Press, and Supported Single-Leg Reach; 2-4 sets of 8-12 repetitions, at an RPE (Rating of Perceived Exertion) of 4-8), and a cool-down period. All sessions incorporated verbal and tactile guidance to ensure safety. Step length and step width were measured pre- and post-intervention using Kinovea software. Results: Data analysis using ANCOVA revealed that the TRX group showed statistically significant improvements compared to the controls. The mean step length in the TRX group increased from 0.53 ± 0.05 m to 0.62 ± 0.04 m (p = 0.002). Furthermore, the mean step width significantly decreased from 0.19 ± 0.03 m to 0.14 ± 0.02 m (p < 0.001). In contrast, the control group showed no significant changes in step length (from 0.54 ± 0.06 m to 0.55 ± 0.06 m) or step width (from 0.18 ± 0.03 m to 0.18 ± 0.03 m). Conclusion: An eight-week TRX training program can effectively ameliorate gait patterns in individuals with visual impairment by enhancing core stability and fortifying non-visual compensatory mechanisms. Implementing this training modality in rehabilitation centers and adapted physical education is recommended. |
