The Effect of Upper Extremity Support Usage on Spatiotemporal Gait Parameters in Individuals With Stroke: A Prospective Cross-over Experimental Study
Background: Arm swing plays a crucial role in maintaining balance, stability, and energy efficiency during normal walking. Following a stroke, many patients use walking aids (like canes or walkers) or clinical supports (like parallel bars) that restrict natural arm movement. This study examines whether these restrictions significantly alter gait mechanics in the stroke population. Methodology: Participants will participate in a cross-over experimental trial. Each participant will walk on a specialized treadmill system (C-Mill VR+) under three randomized conditions: 1. Unsupported walking (no arm support), 2. Single-arm support (using the non-paretic side), 3. Dual-arm support (using both arms). Researchers will record gait speed, step length, cadence, and duration of stance/swing phases for each condition. Expected Outcome: The findings will provide scientific evidence on how different support strategies modulate walking performance. This information will help physical therapists design more effective, individualized rehabilitation programs to improve mobility and quality of life for stroke survivors.
