Purpose: The purpose of this study was to identify the effects of general exercise after blood flow restriction on trunk muscles thickness in children with spastic cerebral palsy.
Methods: Twenty children with cerebral palsy were assigned randomly to an experimental (n = 10) or a control (n = 10) group. The experimental group performed general exercise after blood flow restriction, while the control group performed general exercise alone. The study used an ultrasonic instrument to measure trunk muscles thickness. The Wilcoxon signed-rank test was used to determine differences before and after treatment, and the Mann–Whitney U test was used to determine differences between treatment groups.
Results: From a comparison within the groups, the experimental and control groups showed significant difference in trunk muscle thickness after the experiment (p < 0.05). In a comparison between the two groups, the experimental group showed more significant difference in trunk muscle thickness than the control group (p < 0.05).
Conclusion: Based on these results, general exercise after blood flow restriction effectively improves trunk muscle thickness in children with cerebral palsy.
