Purpose: Foot function is associated with advancing age. Changes in foot function can result in the collapseof the foot arch and cause flat foot. Short foot exercises (SFE) are prescribed for patients with flat feet toprevent secondary clinical problems. This study investigated the effects of SFE on ankle strength and staticand dynamic balance characteristics among older individuals with flat or neutral feet.
Methods: A total 22 older individuals (11 each with flat and neutral feet) underwent progressive SFE over6 weeks. Arch height was measured using a digital caliper. Ankle strength was measured using a BTE primus,and static and dynamic balance were measured using a Zebris treadmill device.
Results: Navicular drop was significantly decreased in the group of older individuals with flat feet. Ankle plantarflexion was significantly increased in both groups (flat feet, p<.00; neutral feet, p<.028). Dorsiflexion andeversion strengths were significantly increased in the group of older individuals with flat feet (p<.000, p<.001).
No significant difference was observed between the groups in the eyes open and closed conditions.
Conclusion: SFE is a clinical prevention program for flat feet in the older population. These results will beused as basic knowledge for clinicians for designing a flat foot rehabilitation program.
