Reliability of isokinetic dynamometry in assessing plantarflexion torque following Achilles tendon rupture

Research output: Contribution to journalArticlepeer-review


Research investigating the most effective management of Achilles tendon injury has been limited by a lack of reliable outcome measurements. Calf strength may be a valid outcome measure, not only in terms of identifying possible risk factors for reoccurrence of rupture, but also as an indicator of recovery. Isokinetic dynamometry has been suggested as an effective tool for measuring the torque of the calf muscles. Such measurements have demonstrated high reliability for the assessment of calf muscle torque in healthy subjects. However, there are no published data to demonstrate the reliability of isokinetic dynamometry in subjects with pathology in the Achilles tendon. The purpose of this study was to assess the inter- and intraobserver reliability of isokinetic dynamometry for assessing plantarflexion torque following Achilles tendon rupture.
