Purpose[edit | edit source]

The Eversion Stress Test evaluates the integrity of the deltoid ligament and aids in determining the degree of instability after a medial ankle sprain[1][2].

Technique[edit | edit source]

The patient is supine, side lying, or seated comfortable with the knee bent 90 degrees and gastrocnemius relaxed. The heel is held from below by one hand by the therapist while the other hand holds the lower leg. While maintaining the ankle in a neutral position, the clinician applies an abduction force to the calcaneus to tilt the talus[1].

Increased talar tilt or pain over the deltoid ligament, when compared bilaterally, indicates a positive test. A spongy or indefinite end feel is indicative of a complete tear[3][4].

In the neutral position, a 2-degree or greater tilt during testing when compared bilaterally indicates a high probability of significant injury to the deltoid[5].

Evidence[edit | edit source]

Studies show that a valgus tilt of the talus occurs when the superficial and deep fibers of the deltoid ligaments are involved. Neutral positioning of the ankle is suggested to test the superficial layer, while testing throughout available ankle range of motion assesses different deltoid fibers[6].

Studies reporting the psychometric properties of this test are scarce and data related to it could not be identified.
