Background: Changes in foot sole shape can result in plantar muscle weakness, lack of proprioception, increased ankle instability, and an inability to balance.
Objectives: To investigated whether different floor surfaces influenced the effect that short-foot exercises have on the foot core system of healthy individuals.
Design: Pretest-posttest control group experimental design.
Methods: This exercise shortens the length of the foot by raising the medial longitudinal arch, strengthening the intrinsic muscle of the sole, and maintaining the shape of the medial longitudinal arch.
Results: There was a significant difference in the angle of the medial longitudinal arch in the mat exercise group (MEG) and vibration exercise group (VEG) before and after the intervention (P<.05). As the arch angle decreased, the arch height increased. Post hoc analysis showed that there was no difference between the floor exercise group (FEG) and MEG or between the MEG and VEG (P>.05). In terms of the weight distribution index (WDI, there was a significant difference in the MEG and VEG (P<.05) but not in the FEG before and after the intervention (P>.05). The post hoc analysis results showed that there was no difference between the FEG and MEG (P>.05).
Conclusion: Various methods to improve the strength of intrinsic muscles of the sole are more effective than no stimulation, and that short-foot exercise combined with sensory stimulation can be recommended for maintaining and increasing the medial longitudinal arch.
