Effectiveness of Robot-Assisted Gait Training on Functional Skills in Children with Cerebral Palsy

Abstract

This study was aimed to investigate the effects of robot- assisted gait training (RAGT) on motor functions, spasticity status, balance, and functionality in children with cerebral palsy (CP). A total of 26 patients who were diagnosed with CP ( diplegic, with gross motor function classification system [GMFCS] levels of 2-5) and who regularly participated in a rehabilitation program were recruited in the study after obtaining approval from their parents. The patients were randomly assigned to two groups. Group 1 (n = 13) received conventional physical therapy (65 minutes, 2 days/week x 8) and group 2 (n = 13) received 25minutes of RAGT (RoboGait) in addition to conventional therapy (CT; 40 minutes, 2 days/week x 8). GMFCS was used to evaluate motor functions and the Modified Ashworth Scale was used to evaluate spasticity. The pediatric Berg balance scale, pediatric functional independence measure, and timed up and go tests were employed to assess balance and functional status. The evaluations were performed at baseline and after 8 weeks of therapy. Both rehabilitation methods led to a statistically significant decrease in spasticity (p< 0.05); however, there was no difference in this improvement of spasticity between the groups (p> 0.05). Both groups exhibited significant improvements in functional independence, balance, and performance at the end of therapy (p< 0.05), and there was no significant difference between the groups (p> 0.05). The results of this study show that addition of RAGT to CT for 8 weeks is not superior to CT alone in children with CP.
