Abstract
A group of 35 paraplegic subjects using reciprocating walking orthoses have been examined in order to gain an insight into the potential functional benefits of using such devices. Measurements have been made of walking speeds and of the energy costs of ambulation using an established technique based on heart rate recordings. It was found that orthotically aided walking for paraplegics was slow and energy costly compared with both normal walking and wheelchair propulsion and, as it additionally requires the use of a walking aid in both hands, cannot be considered to confer the functional benefits frequently claimed for it. Nevertheless, the majority of the subjects studied liked their orthosis and did well in it, with many subjectively reporting improvements in mobility and independence.
