The aim of this case study was to identify the effect of a powered
hip orthosis on the kinematics and temporal-spatial parameters of walking by a
patient with spinal cord injury (SCI). METHODS: Two orthoses
were evaluated while worn by an incomplete SCI subject with a T-8level of injury.
Gait evaluation was performed when walking with an Isocentric Reciprocating Gait
Orthosis (IRGO) and compared to that demonstrated by a newly powered version of
the orthosis; based on the IRGO superstructure but incorporating powered hip
joints using an electrically motorized actuator that produced active hip joint
extension and flexion. FINDINGS AND OUTCOMES: The powered hip orthosis, when
compared to the IRGO, increased the speed of walking, the step length and also
the cadence demonstrated by this subject. Vertical and horizontal compensatory
motions with new orthosis decreased. Hip angles when walking with this orthosis
were comparative to those demonstrated by normal walking patterns. CONCLUSIONS:
The hip actuator produced positive effects on the kinematics and temporal-spatial
parameters of gait during level-ground walking trials, resulting in an
alternative approach to walking by SCI patients.
