Purpose: Walking on sand could be a suitable intervention for the treatment of individiuals with both anterior cruciate ligament reconstruction and pronated feet. However, there is a lack of knowledge about the effects of walking on sand on gait biomechanics and muscle activities in theses patients. Thus, the purpose of this study was to assess how sand training affect the gait mechanics of people who had both pronated feet and anterior cruciate ligament reconstruction.
Methods: Twenty-eight adult males with pronated feet and anterior cruciate ligament repair were randomly assigned to the intervention and control groups. The walking task was done on an 18-meter walkway at a consistent velocity. Muscle activities and ground reaction forces were recorded using a surface bipolar electromyography system and a Bertec force plate, respectively.
Results: Significant group-by-time interactions were observed for anterior and posterior reaction forces (p<0.019; d=0.49-0.66). Posthoc analysis demonstrated a significant increase for anterior and posterior reaction forces in control but not in the intervention groups. Moreover, significant group-by-time interactions were observed for vastus activities during loading phase (p=0.033; d=0.88).
Conclusion: Results demonstrated greater vastus lateralis activities during loading phase at intervention group but not in the control group. Adult males with anterior cruciate ligament reconstruction and pronated foot experienced an improvement in muscle activity (e.g., vastus lateralis) due to sand training.
