In an adult paraplegic walking with the ParaWalker, electrical stimulation of the stance-side gluteal muscles (gluteus maximus and medius) reduces the force applied through the crutches during the gait cycle. In this study, five posttrauma, fully rehabilitated, complete paraplegic adult men walked using their ParaWalkers both without and with electrical(More)
We assessed the outcome after simultaneous multiple operations performed on 18 children with spastic diplegia, with emphasis on the changes in the physiological cost index (PCI) of walking. Fourteen patients had a measurable reduction at one year, but the more severely affected patients took up to two years to reach a new functional plateau. The level of(More)
In a prospective study of 29 consecutive cases of tibial tubercle advancement, the patients were assessed on the Larson knee chart preoperatively, three years postoperatively, and again after a minimum of six years (range, six to eight years; mean, 7.2 years). Only one patient was lost to follow-up evaluation. The overall results show that at three years,(More)
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(More)
Seventy-two normal children aged between three and 12 years were assessed to establish their walking function. Speed of walking and heart rate were monitored continuously, both barefoot and in shoes, over eight consecutive lengths of a 25m walkway. Since heart rate is affected by speed, the physiological cost index (PCI)--which combines the two(More)
Ten subjects with neurological lesion levels between T4 and T9 have been evaluated in the laboratory at ORLAU using their orthosis in its mechanical form alone (without FES assist). Initially the oxygen consumption at rest was measured. Then the patients were asked to walk (orthotic gait) at their preferred constant steady speed for a period of 5 minutes.(More)
Incomplete spinal cord injury at ASIA (D) level often leads to major gait re-education attempts for patients and staff. Walking prognosis usually depends upon muscle power loss, degree of spasticity present, type of lower limb joint deformity developing and availability of treatment. As an adjunct to physical examination and observation, instrumented gait(More)
The hip guidance orthosis which allows paraplegic children to walk reciprocally has been further developed for adult traumatic paraplegics. Since December 1981, 11 adult complete paraplegics have walked using this device, designated a 'Parawalker'. Our understanding of the mechanics of this form of ambulation and our early work with functional electrical(More)
Cation transport and electrolyte composition were studied in leucocytes from 17 patients with uncomplicated essential hypertension. Significant increases in cell sodium and water contents, associated with a depression of the rate-constant for active sodium efflux, were found in the hypertensive patients. These abnormalities in cell sodium transport may(More)
