Abstract:

Objective To observe the effect of vestibular regulation technique combined with conventional musculoskeletal rehabilitation on the foot posture of adolescents with flexible flatfoot. Methods Fifty-eight patients were randomly divided into a control group and an experimental group， with 29 patients in each group. The control group received musculoskeletal rehabilitation， while the experimental group received vestibular regulation combined with musculoskeletal rehabilitation. Both groups were treated for two weeks. Three-dimensional foot scans were conducted before and after the intervention to collect data on arch height， arch type， arch width coefficient， footprint area coefficient， calcaneal valgus angle， and hallux valgus angle. Results （1）Arch height： Both the control and experimental groups showed increased arch height in both feet after the intervention （P < 0.05）， with the experimental group showing better results than the control group （P < 0.05）. （2）Arch type： Both groups showed improvement in arch type in both feet after the intervention （P < 0.05）， with no significant difference in efficacy between the two groups （P > 0.05）. （3）Arch width coefficient： The control group showed improvement in the left foot arch width coefficient after the intervention （P < 0.05）， but no significant improvement in the right foot （P > 0.05）. The experimental group showed improvement in both feet （P < 0.05）， with no significant difference in efficacy between the two groups （P > 0.05）. （4）Footprint area coefficient： Both groups showed improvement in the footprint area coefficient in both feet after the intervention （P < 0.05）， with no significant difference in efficacy between the two groups （P > 0.05）. （5）Calcaneal valgus angle： The control group showed no significant improvement in the calcaneal valgus angle in both feet after the intervention （P > 0.05）， while the experimental group showed improvement （P < 0.05）. （6） Hallux valgus angle： The control group showed no significant improvement in the hallux valgus angle in both feet after the intervention （P > 0.05）， while the experimental group showed improvement （P < 0.05）. Conclusion On the basis of conventional musculoskeletal rehabilitation， the integration of vestibular regulation techniques can effectively improve the height， type， width coefficient of the arch， footprint area coefficient， calcaneal valgus angle， and hallux valgus angle of the foot in adolescents with flexible flatfoot， and improve their foot posture.
