What maneuver is used to test for posterior tibialis tendon dysfunction?

Resisted inversion and plantarflexion is the correct maneuver to test for posterior tibialis tendon dysfunction. This tendon is crucial for foot mechanics, providing support for the medial arch and assisting with foot inversion and plantarflexion. During the resisted inversion and plantarflexion test, the clinician asks the patient to perform these movements against resistance, which isolates the function of the posterior tibialis tendon. If there is weakness or pain during this maneuver, it indicates possible dysfunction of the tendon, suggesting a pathology such as tendinitis, tears, or other injuries associated with the posterior tibialis.

The other options do not specifically isolate the posterior tibialis tendon or are not indicative of its function. Active dorsiflexion and eversion primarily test the anterior tibialis or the peroneal tendons rather than the posterior tibialis. Passive inversion and plantarflexion may not accurately demonstrate the strength or integrity of the tendon since they do not involve active muscle engagement. Squatting and jumping involve multiple muscle groups and dynamic functions of the lower extremity, which would not specifically highlight issues with the posterior tibialis tendon.
