Purpose This study aimed to investigate changes in dynamic balance after backward walking training in children with spastic hemiplegic cerebral palsy. Methods To control potentially confounding variables and to assess the immediate effect of backward walking training, the same exercise was repeated once over a 20 minute period. The Single Leg Standing Test (SLS), Symmetry Ratio (SR), Timed Up and Go Test (TUG), Timed Stair Climbing Test (TSC) scores were collected and analyzed using the Wilcoxon rank sum test. Results There was no significant increase in single leg standing time on the less affected side (p>0.05). However, single leg standing time on the affected side, the symmetry ratio, the timed up and go test and timed stair climbing test were significantly increased (p<0.05). Conclusion Our results suggest that, backward walking training can be usefully applied as a programs to improve the dynamic balance of children with spastic hemiplegic cerebral palsy.
