A child could walk independently even though he had severe injury on his femoral nerve due to the penetrating wound in the medial thigh. We measured and analyzed his gait performance in order to find the mechanisms that enabled him to walk independently. The child was eleven-year-old boy and he could not extend his knee voluntarily at all for a month from the injury. His gait analysis was performed five times(GA1~GA5) for sixteen months. His temporal-spatial parameters were not different significantly after the GA2 and GA3 test. Significant asymmetries of the lower limb joint angles in the GA1 were not observed in the GA5. The EMG patterns were restored their normal or near normal patterns after the GA5, but the sagittal joint moments had quite different patterns from the normal patterns even after the GA5. From this study, we found that, although the independent walk was possible with a paralyzed knee extensor, the damping function of the knee joint in the stance phase hardly be compensated by other muscles.
