About
This is a randomized controlled trial (RCT) regarding the conservative treatment of chronic ankle instability (CAI) with an impairment based rehabilitation program. Individuals with CAI have deficits in neuromuscular control and altered gait patterns. Ankle destabilization shoes are used clinically and may improve neuromuscular control by increasing lower extremity muscle activation, which may improve gait patterns. The investigators' purpose is to determine whether a 4-week rehabilitation program that includes ankle destabilization shoes (experimental) has beneficial effects on self-reported function and ankle gait kinematics compared to traditional rehabilitation without destabilization shoes (control) in CAI patients. In addition, the investigators will compare ankle strength and balance between CAI patients and healthy individuals with no history of ankle injury prior to the 4-week rehabilitation. The investigators hypothesize the experimental group will have greater improvement in self-reported function and frontal and sagittal plane kinematics during walking compared to the control group. In addition, the investigators hypothesize that patients with CAI will have a decrease in ankle strength and balance when compared to healthy individuals. The design is a single-blinded randomized controlled trial. Forty CAI patients will complete baseline self-reported function questionnaires and walking gait trials and then be randomized into control and experimental groups. Both groups will complete 4-weeks of supervised rehabilitation with or without destabilization shoes and then repeat the questionnaires and walking trials.
