RESUMO
BACKGROUND: Horse riding simulator (HRS) is an electronic horse, working under the principles of hippotherapy. It is one of the advanced therapeutic methods to improve postural control and balance in sitting, which could be recommended in the rehabilitation of cerebral palsy if real horses are unavailable. OBJECTIVE: To investigate the therapeutic effects of HRS on sitting motor function in children with spastic diplegia and evaluate the changes in sitting motor function at different periods of time (4, 8 and 12 weeks). METHODS: This study is a randomized controlled trial conducted over a period of 12 weeks. Thirty children with spastic diplegia age between 2 and 4 years with Gross Motor Function Classification System (GMFCS) Level I-III were included and divided into two groups. The control group received the conventional physiotherapy while the experimental group received HRS along with conventional physiotherapy. Sitting motor function was assessed by Gross Motor Function Measure (GMFM)-88 (sitting dimension B) at baseline, 4, 8 and 12 weeks. Pre- and post-intervention scores were measured and analysed. RESULTS: The baseline characteristics were similar in both groups before the intervention with p > .01. The observed mean value of GMFM in both groups improved over a period of 12 weeks. The results denote that the sitting motor function gradually improved over a period of time in both groups and the experimental group showed significant improvement (p < .01) than the control group in all the weeks. CONCLUSION: The study results confirmed that gradual improvement in sitting motor function was observed in both groups. Children exposed to HRS show better improvement than the children in the control group. It was concluded that HRS is effective in improving the sitting motor function in children with spastic diplegia and the continuous provision of HRS in longer duration provide more benefits than the shorter duration.
