This study developed the posterior walker for children with cerebral palsy (CP) and studies its efficacy on gait parameters, energy expenditure and perceived exertion. The walker was designed and constructed according to stability, safety and foldability. Five children with CP participated. They had received a practice period of 1-month to familiarize themselves with both types of posterior walker (commercial posterior walker and new walker). Spatiotemporal gait was evaluated by GAITRite analysis, and energy expenditure determined according to the method described by Schlough et al. (2005) at pre and post practice once a week for 4 weeks. Rate of perceived exertion was also measured using the method described by Mattsson (1997). The new 4-wheeled posterior walker was constructed with dimensions of 57 cm x 67 cm x 48 cm and it weighed 6 kg. When ambulating with the new walker, the gait parameters, energy expenditure and perceived exertion of the children with cerebral palsy were comparable with using the commercial posterior walker in each period of measuring. There was also no time effect on those variables after training with either the commercial or new walker. These results indicated that the new walker could be used as an ambulation aid for children with cerebral palsy. However, the training program should be intensified to yield more benefit on those parameters.en-USChiang Mai Medical JournalOriginal Articles
