Purpose The purpose of this study was to investigate the effects of short term intensive treadmill training on balance and gait in children with cerebral palsy. Methods A total of 20 subjects consisted of 10 fast gait treadmill training groups and 10 normal gait treadmill training groups. Treadmill training without weight support was performed 5 times a week for 20 minutes and 2 weeks. Pediatric Balance Scale (PBS)), Timed up and go test (TUG), and Stride length were used to evaluate the balance and gait before and after intervention. Result The results of this study showed that there was a significant difference in both the FTT groups and NTT groups before and after the PBS change (p <0.05), and also between the groups (p <0.05).There were significant differences in the TUG change between the FTT groups and NTT groups before and after the intervention (p <0.05), and between the groups (p <0.05). Before mediating in comparing stride length changes. There was no significant difference between the two groups (p> 0.05) in the postcomparison comparison and no significant difference (p> 0.05). Conclusion Short term intensive treadmill training in children with cerebral palsy is effective in increasing balance ability and gait function, and FTT affects balance and gait more than normal treadmill training.
