Effect of Increase the First Metatarsophalangeal Joint Extension and Ankle Dorsiflexion Using an Elastic Band on Ankle Stability

Background It is known that ankle stability is required to maintain balance. However, metatarsophalangeal joint movement is related to ankle stability, there is no study that increases the first metatarsophalangeal joint extension and ankle dorsiflexion affect together in ankle stability. Objectives The purpose of this study was to determine the effect of an elastic band on ankle stability during one leg standing on an unstable surface. Methods A total of 12 healthy adult volunteers were recruited for this study. The total distance of the marker which presents the center of mass displacement was measured using the camera - Kinovea®. The difference between with and without an elastic band was analyzed using the paired t-test with p < 0.05 as the significant level. Results The total distance of the center of mass was significantly decreased (p < 0.001) when one leg standing on an unstable surface with an elastic band versus without an elastic band. Conclusions The present findings demonstrate that using an elastic band on the first metatarsophalangeal joint and the ankle improves ankle stability during one leg standing on an unstable surface in healthy adults.
