Reliability of the Anterior Drawer and Talar Tilt Tests Using the LigMaster

Context: Joint arthrometers have been developed to help determine the severity of ligament sprains. Objective: To establish intratester and intertester reliability of the talar inversion and anterior drawer tests using the LigMaster. Design: Intratester reli-ability was investigated using a repeated-measures design. Intertester reliability was investigated using 2 different clinicians testing subjects on the same day. Setting: Athletic training research laboratory. Participants: Thirty participants volunteered for this study. Main Outcome Measurements: Anterior displacement and talar inver-sion were measured using the LigMaster. Results: Intrarater reliability was.74 for the talar inversion test and.65 for the anterior drawer test. Interrater reliabilities for the talar inversion and anterior drawer tests were.76 and.81, respectively. Conclusions: The LigMaster joint arthrometer is a reliable tool for measuring talar inversion and anterior displacement at the ankle. Keywords: ankle, laxity, stress test, inversion Foot and ankle injuries are prevalent in athletes, accounting for nearly 25 % of their injuries.1 The most common injury is a lateral ankle sprain causing damage to the anterior talofibular ligament, calcaneofibular ligament, and/or posterio
