The notion of limb dominance has been commonly used in the upper extremity, yet the two lower extremities are often treated as equal for analytical purposes. Attempts to determine the effects of limb laterality on gait have produced conflicting results. The purpose of this study was to determine if limb dominance affects the vertical ground reaction force (vGRF) and center of pressure (COP) during able-bodied gait. The Parotec system (Paromed GmbH, Germany) was used to collect plantar foot pressure data. 15 subjects volunteered to participate in this study. The coefficient of variation (CV) of the COP displacement in the medio-lateral (ML) direction and the variability of peak force beneath the lateral forefoot in the non-dominant foot were significant greater than in the dominant foot. Moreover, COP velocity in the anterior-posterior (AP) direction during the terminal stance phase showed greater value in the dominant foot. Our study provides support for limb laterality by showing limb dominance affected the vertical ground reaction force and center of pressure during walking gait. This finding suggests it is an important issue in movement science for clinicians and would assist in improving sports performance and rehabilitation program. |
