Abstract
The research investigated the feasibility and effectiveness of an interactive feedback system integrating wearable sensors and real-time visual feedback for pre-vocational lower limb motor function in individuals with intellectual disabilities (ID). Using a single-group pre- and post-test design, 12 participants completed five training sessions focusing on knee extension, plantarflexion, and do rsi flex ion. Outcomes were evaluated through gait stability metrics (total deviation, walking time, and steps) and surface electro myo graphy (sEMG) signals. Significant improvements were observed in walking time (reduced from 14.4 to 10.2 seconds, p=.008) and step count (from 25.3 to 18.6 steps, p=.008), reflecting enhanced gait stability. Although the total gait deviation improvement was not statistically significant, a moderate positive correlation was found between knee extension improvements and gait stability. These findings highlight the crucial role of vastus lateralis and vastus medialis strengthening in gait stability enhancement. The research confirms that wearable sensors combined with interactive feedback effectively support lower limb motor function in individuals with ID, emphasizing the importance of individualized training approaches.
