Stroboscopic Vision and ACL Reconstruction

The UNC MOTION Science Institute is seeking volunteers with a history of anterior cruciate ligament (ACL) reconstruction surgery and healthy controls for a research study on the effects of stroboscopic vision on walking gait biomechanics, and how the somatosensory function may influence these changes. Individuals who have injured their ACLs are at a high risk of developing post-traumatic osteoarthritis, in part due to altered gait biomechanics. Stroboscopic vision has been shown to alter biomechanics in other tasks and populations, but its effects on walking biomechanics following ACL reconstruction is unknown.

Age & Gender

18 years ~ 35 years
Male, Female, Gender Inclusive

Visit Availability

Standard business hours (M-F, 8-5)
Extended hours (M-F, early morning or evening)
Weekend hours, if needed

Location

United States (Nationwide)

What will be asked of you

At your visit, you will meet with a member of the study team and complete a gait biomechanics assessment with and without stroboscopic vision. You will also complete measures of your somatosensory function (joint position sense and vibratory perception), single-leg balance, visual acuity, muscle function, and fill out questionnaires.

Incentives
