Abstract
BACKGROUND: Lateral ankle sprain is the most common injury in basketball, and many of these sprains resulted in residual functional deficits. This study aimed to compare ankle strength and range of motion, and postural balance between competitive basketball players with and without lateral ankle sprain. METHODS: This was a cross-sectional study involving 42 male competitive basketball players. Subjects were divided into the injured and uninjured groups based on self-reported questionnaires. Ankle range of motion (ROM) was measured using a goniometer, ankle isokinetic strength testing performed using Biodex System 4 PRO, and single-leg stability tests performed using Biodex Balance System SD. RESULTS: Between the injured and uninjured ankles, there was a decrease in plantarflexion ROM (44.89 +/- 6.85 vs. 50.75 +/- 9.31, P<0.05) and an increase in eversion ROM (14.50 +/- 5.63 vs. 11.74 +/- 4.53, P<0.05). There was a reduction in inversion and plantarflexion strength at 30 degrees/s peak torque and 120 degrees/s peak torque (P<0.05). However, no significant difference observed in the postural stability indexes between the two groups. CONCLUSIONS: This study proves that there are residual ROM and strength deficits after an ankle sprain, however, these deficits do not affect their balance ability.
