La. Harvey et al., A COMPARISON OF THE ATTITUDE OF PARAPLEGIC INDIVIDUALS TO THE WALKABOUT ORTHOSIS AND THE ISOCENTRIC RECIPROCAL GAIT ORTHOSIS, Spinal cord, 35(9), 1997, pp. 580-584
This study compared the attitude of paraplegic individuals to the Isoc
entric Reciprocal Gait Orthosis (IRGO) and the Walkabout Orthosis (WO)
, after they had been given the opportunity of using both. Ten complet
e T9-12 paraplegic patients participated in this randomised cross-over
design, Initially the subjects learned to walk with the first orthosi
s before taking it home for a 14 week home trial period. The same proc
ess of training and trialing the orthosis at home was then repeated wi
th the second orthosis. Attitudes to specific aspects of the orthoses
were assessed by an 18 point questionnaire and overall attitudes were
inferred after determining the amount of time that subjects used the o
rthoses at home and determining which orthosis the majority of subject
s wanted to keep at the end of the study. The main finding was that su
bjects did not perceive any significant differences between the two or
thoses, That is: (i) the questionnaire did not detect significant diff
erences in attitudes to the two orthoses; (ii) there was no significan
t difference in the number of subjects that preferred one orthosis to
the other, at the end of the study, and (iii) subjects did not derive
more use from one orthosis than the other over the two 14 week home tr
ial periods. In addition, it was found that few subjects wore either o
rthosis more than once every 2 weeks and that subjects were primarily
using the orthoses for therapeutic purposes. This latter finding was s
upported by the results of the questionnaire that revealed that subjec
ts found both orthoses to be useful for standing but not useful for pe
rforming more purposeful tasks. It was concluded that when subjects ar
e primarily using the WO and IRGO for therapeutic purposes, they do no
t readily perceive differences between the two.
