title: [Gait analysis in patients with injuries of spinal cord and nerve root].
abstract: In 102 normal subjects an IGI-3 gait analysis system was used to determine the normal level of walking. The results showed that the time of pressure appeared under foot and the sagittal joint movement of the lower extremities were similar to these reported previously. The forward and backward acceleration showed a single positive peak during swing phase, while the upward and downward acceleration showed two positive peaks. At heel contact of stance phase, the acceleration of all dimensions brought about a big negative peak. The variations in gait pattern were distinguished according to the curve characteristics and activity of muscles in the low extremities. The relations between the degrees of spinal cord injury and the gait characteristics were studied. The result indicated that the patterns of gait depend on the degree of injury. The more smooth acceleration curves, the better gait, and the abnormal gait is characterized by multiple peaks of pressure curves.
