Abstract

Background: The purpose of this study was to determine the effects of insoles on the plantar pressure distribution during squat exercise in subjects with calf muscle shortness. Design: Cross-sectional Study Methods: Thirty subjects were participated in each fifteen subjects of a control group and an experimental group with calf muscle shortness. The participants were allocated in control group or experimental group according to knee-to-wall test. They were asked to perform squat exercise at hip flexion angle of 20° and knee flexion angle of 45° across three conditions with insole(2.0cm and 3.5cm) and without insole. The plantar pressure distribution was measured using Pedoscan equipment. In order to find out whether there is a significant difference in the plantar pressure distribution between the groups and the height, the two-way mixed ANOVA test was used and the statistical significance level was .05. Results: As a result of the study, the plantar pressure distribution between the group and the height showed a significant interaction effect(p<.001). There was no significant difference according to the insole height of 2.0cm and 3.5cm in all the control groups and the experimental group. Conclusion: We found that the plantar pressure distribution shifted backward during squat exercise by wearing the insole to subjects with shortening of the calf muscle. We suggest that wearing an appropriate height of insole may change the plantar pressure distribution during squat exercise in subjects with calf muscle shortness.
