Purpose: This study was to identify the change of the movement strategy according to restricted ankle motion during sit to stand movement by analyzing the biomechanics of the lower extremity. Methods: A total of eighteen subjects voluntarily participated in the experiment. We classified 18 subjects into 3 groups of 6 persons (NFR: non flexion restriction, DFR: dorsi flexion restriction, PFR: plantar flexion restriction) and measured the biomechanical factors of the lower limb during sit to stand movement. The ground reaction force was measured using a force plate, and the other factors were measured using an infrared camera. The non-parametric test was used to analyze the changes in the biomechanical factors of the lower limbs according to restricted ankle motion. Results: Biomechanical factors were statistically significant difference in ankle-restricted groups. In the DFR group, the maximum joint force, the displacement of the center of gravity and the maximum ground reaction force showed statistically significant differences, however the maximum flexion angle was not. In the PFR group, the maximum joint force, the displacement of the center of gravity showed statistically significant differences, however the maximum ground reaction force and maximum flexion angle was not. Conclusion: These results show that restriction of ankle dorsi flexion use the strategy using the force of the unaffected lower limb, and restriction of ankle plantar flexion use the strategy positioning the center of gravity within the base of support.
