Abstract Objective To evaluate whether a battery of clinical assessments for acute lateral ankle sprain (LAS) can be used to predict long-term recovery. Design Cohort study Setting University biomechanics laboratory Participants Eighty-two individuals were assessed using a clinical test battery within two-weeks of incurring a first-time LAS. Main Outcome Measures The clinical test battery included scores on the ‘talar-glide’ (deg), anterior-drawer, talar-tilt, figure-of-eight [figure8] for swelling (mm), knee-to-wall (mm) and hand-held goniometric range-of-motion [inversion; eversion; plantar-flexion (in degrees)]. Scores on the the Cumberland Ankle Instability Tool (CAIT) taken 12-months after the clinical test battery were used to classify participants as having Chronic Ankle Instability (CAI) or as being LAS ‘copers’ Results Forty percent of participants were designated as having CAI with 60% being designated as LAS copers. A logistic regression analysis revealed that a combined model using scores from the talar-glide, talar-tilt and anterior-drawer tests in addition to plantar-flexion ROM was statistically significant (p <0.01) and correctly classified cases with moderate accuracy (68.8%). The final model had moderate sensitivity (64%) and good specificity (72%). Conclusions The clinical tests utilised in this investigation have limited predictive value for CAI when conducted in the acute phase of a first-time lateral ankle sprain injury.
