Effects of whole-body vibration combined with action observation on gross motor function, balance, and gait in children with spastic cerebral palsy: a preliminary study

This study evaluated the effects of whole-body vibration (WBV) com-bined with action observation on gross motor function, balance, and gait in children with spastic cerebral palsy. The participants were randomized into the WBV combined with action observation (WBVAO) group (n=7) and the WBV group (n=7). The WBVAO group received WBV combined with action observation training, and the WBV group received WBV training for 4 weeks. Both groups received 30 min of training a day, 3 times a week. All participants completed the 5 times sit to stand (FTSTS) test, Timed Up and Go (TUG) test, pediatric reach test, 10-m walk test, 6-min walk test (6MWT), and timed up and down stair (TUDS) test before and after the training intervention. Moreover, the participant’s Gross Motor Function Measure (GMFM) and Pediatric Balance Scale (PBS) scores were assessed. Both the WBVAO and WBV groups demonstrated significant increases in the scores of FTSTS test, GMFM (D and E dimensions), PBS, TUG test, 6MWT, and TUDS test. The WBVAO group improved more significantly compared to the WBV group based on the scores of the FTSTS test, GMFM (D dimension), PBS, 6MWT, and TUDS test. WBV combined with action observation improved lower extremity functional strength, gross motor function, and balance and gait in children with cerebral palsy. These results suggest that WBV combined with action observation is both feasible and suitable for individuals with cerebral palsy.
