Reliability of the anterior drawer and talar tilt tests using the LigMaster joint arthrometer.

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 reliability 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 inversion 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.
