Abstract
The Oswestry ‘Parawalker’ orthosis has been supplied to 15 adult thoracic level complete paraplegic patients enabling them to achieve a reciprocal gait with an inherent low energy demand. In order to further off-load the work demands on the upper limb girdle musculature during ambulation, three of these patients have undergone electrical stimulation of the gluteal muscles in stance phase. This was shown to increase the stability of the adduction and also provided forward propulsion by driving the stance-leg into extension. Bilateral stimulation of the quadriceps muscles has been shown to facilitate standing and sitting in the orthosis. Using a Kistler force platform, the crutch impulse can be seen to be reduced by as much as 36%. We speculate that this leads to a similar order of reduction in the work done by the upper limbs in these patients.Keywords
