Abstract

Ankle sprain is a commonly recurring sports injury. This study aimed to compare the rehabilitation effects of resistance and balance training programs in patients with recurrent ankle sprain. Patients with recurrent lateral ankle sprain completed a home-based rehabilitation program comprising resistance training (RT; n = 27) or balance training (BT; n = 27). RT consisted of exercises using elastic tube bands, and BT consisted mainly of exercises performed using a variety of balance tools. Exercises were performed for 6 weeks, twice a day for 20 min, 5 days per week. Isokinetic eversion strength, Y-Balance test and hop tests, and foot and ankle outcome score (FAOS) were evaluated. Both RT and BT significantly improved strength and dynamic balance (p < 0.05). Compared to RT, BT also significantly improved the outcome of the crossover hop test (p = 0.008). The changes reflected group and time in pain (p = 0.022), sports (p = 0.027), and quality of life (p = 0.033) of FAOS were significantly greater in BT than RT.

Highlights

Repetitive ankle sprain can progress to chronic ankle instability (CAI), resulting in overall weakness of the ankle, pain, and limited range of motion (ROM) [3]
CAI occurs in 40–70% of individuals with repetitive ankle sprains, and factors contributing to the development of CAI include the severity of the injury, structural deformity, and inadequate rehabilitation [4,5]
More specific results of this study showed that balance training (BT) improved pain relief, sports activity, and quality of life compared to resistance training (RT)

Summary

Introduction

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Ankle sprain occurs mainly on the lateral side due to inversion of the ankle, and is a common sports injury with a high recurrence rate [1]. Recurrence of ankle sprains was reported as 12–47%, and individuals with a history of ankle sprains have a 3.5-fold higher injury rate than healthy individuals [2]. Repetitive ankle sprain can progress to chronic ankle instability (CAI), resulting in overall weakness of the ankle, pain, and limited range of motion (ROM) [3]. CAI occurs in 40–70% of individuals with repetitive ankle sprains, and factors contributing to the development of CAI include the severity of the injury, structural deformity, and inadequate rehabilitation [4,5]
