Clinical Trial

Determining the biomechanical deficits in individuals with chronic ankle instability

IRB Protocol Number STU00215245

Zoe Villamar Zoevillamar2018@u.northwestern.edu

Objective

This study is looking for healthy people who have had an ankle sprain or instability in the past to study: 1) to estimate how load stabilizes the ankle and 2) to estimate how muscle contraction stabilizes the ankle. You may be participating in experiments satisfying one or both objectives. This will increase our understanding of why individuals experience chronic ankle instability.

Participants will be asked to sit while a motor moves their ankle under conditions of load, muscle relaxation, and muscle contraction.

Who Can Participate

A history of one significant ankle sprain that resulted in at least one interrupted day of desired physical activity AND you experience recurrent sprains AND/OR you have a history of the ankle “giving way” or feeling unstable. 18 – 35 years old; No history of lower extremity surgery; No history of fracture in the lower extremity that required realignment; No current or history of orthopedic diagnosis to the lower extremity (ex: Achilles tendinopathy, Achilles tendon rupture); Available to come to the SRALab for one 1-hour session and up to two 3-4 hour sessions

Compensation

Provided upon participation of study.

Age Range

18-35
