A comparative trial of two walking systems for paralysed people

Abstract

A trial has been performed to compare two designs of reciprocal walking orthosis for paralysed people—the hip guidance orthosis (HGO) from Oswestry, England, and the reciprocating gait orthosis (RGO) from New Orleans, USA. Eighteen male and 4 female paraplegic subjects used each orthosis for 4 months, in a crossover study. All aspects of the provision and use of the devices were monitored, and a variety of assessments were made. Fifteen subjects were able to use both orthoses, 5 were unable to use either and 2 succeeded with the HGO but not the RGO. At the end of the trial 12 subjects chose to keep the RGO, 4 the HGO, and 6 kept neither. Those choosing the RGO liked its appearance; those choosing the HGO liked the speed of donning and doffing. The RGO was about 50% more expensive to supply than the HGO. © 1991 International Medical Society of Paraplegia.
