Abstract
Ankle injuries are common in a wide variety of individuals, ranging from physically-active students to ballet dancers, and from college athletes to military personnel. It has been estimated that nearly 28,000 ankle injuries occur in the United States each day. If specific laboratory measurements can be shown to be sensitive enough to detect differences between healthy controls (CON) and individuals with chronic ankle instability as a result of lateral ankle sprains (CAI-LAS), those measures can be utilized in assessments of injury risk, assist in monitoring rehabilitation from injury, and be incorporated as measures of potential improvement in training interventions. The purpose of this study was to examine if differences in laboratory measures of ankle flexibility, proprioception, strength, and postural stability existed in soccer players, with and without chronic ankle instability. The laboratory measurements for this study included ankle range of motion (ROM), the Star Excursion Balance Test (SEBT), lower leg musculature size, threshold to detect passive motion (TTDPM), strength, time to peak torque (TTPT), static postural stability, and dynamic postural stability. ROM was significantly worse (p ≤ 0.039) in CAI-LAS. Performance on the SEBT was significantly lower for the anterior reach (p ≤ 0.040), posteromedial reach (p ≤ 0.016), and composite score (p = 0.018). Inversion TTDPM was 56.5% worse in CAI-LAS compared to CON (p = 0.016). There was not a statistically significant difference (p = 0.181) for eversion TTDPM, however CAI-LAS had 24.1% greater error. There were no significant differences reported between the groups for musculature size, strength, TTPT, or postural stability, however, trends did exist in the data that are indicative of diminished neuromuscular characteristics. Utilization of ankle ROM and proprioception assessments as part of a screening tool may highlight neuromuscular deficiencies that can be improved with more individualized training aimed at preventing injury occurrence.
