Assessing Joint Laxity after Lateral Ankle Sprain: Implications for Injury Management

Joint Laxity following Lateral Ankle Sprain (LAS)

The Study investigates the presence of absence of Ankle joint and Subtalar laxity in people with and without a history of LAS.



Twelve subjects with a history of unilateral LAS and eight healthy controls were examined by two blinded examiners.



One examiner performed physical examination on each ankle by using the anterior drawer (AD), Talar tilt (TTPE), and medial subtalar glide (MSTG) tests. The second performed stress fluoroscopy taking AP views with and without a manually applied supination stress.



Laxity in…
previously injured subjects: 75%
Uninjured subjects: 25%


In a nutshell…

Ongoing instability following Lateral ankle sprain predisposes patients to repeat sprains as well as Achilles and other tendon overuse injuries. A strengthening program following the acute phase of an Ankle sprain will help keep these issues at bay.
