The viability of paraplegic gait incorporating knee tlexion during the swing phase was studied in a Hip-Knee-Ankle-Foot-Orthosis with automatic mechanism for the control of the knee hinge lock. Two complete thoracic spinal cord injured subjects (1 male T12, 1 female T4) participated in a comparative trial of gait in the ARGO-like test orthosis with locked knee and the same orthosis with engaged knee control mechanism. Subjective findings were recorded with respect to experienced safety, usability and cosmesis. Kinematics, kinetics and oxygen uptake were measured to assess gait performance and energy efficiency. Both subjects were able to walk in the orthosis unassistedly for prolonged periods on varying surfaces. Knee flexion was felt to facilitate ambulation on uneven terrain, and to improve cosmesis of gait. Due to an experienced feeling of insecurity, neither of the subjects would prefer to use the test orthosis instead of their own ARGO for daily use. The introduction of knee flexion in the gait pattern was found to have little or no effect on kinematic and kinetic outcome variables. The effects found tended to be different for subject I and subject 2. A significant difference was found for subject 1 in the crutch force time integral (or linear impulse), which was higher in the orthosis with controlled knee flexion. A significant reduction in the crutch peak force applied during the swing phase was found for subject 2. Energy consumption was found to be higher in the orthosis with controlled knee flexion for subject I, and lower for subject 2. It was concluded that the incorporation of knee flexion in the swing phase may provide a modest added value to paraplegic orthotic gait, not so much perhaps with respect to energy consumption, but more likely with respect to functional aspects and cosmesis. |
