About

A randomized controlled trial investigating the effects of a 4-week ankle rehabilitation program on high school athletes with chronic ankle instability.

Full description

A randomized controlled trial investigating the effects of a three different 4-week ankle rehabilitation programs on high school athletes with chronic ankle instability. We will use questionnaires to assess subjective level of function and clinical measures to assess clinical functionality via static and functional balance.

Enrollment: 43 patients

Sex: All

Ages: 15 to 18 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• active for at least 1.5 hours a week, a history of at least 1 significant ankle sprain that required medical intervention, repeated symptoms of pain, swelling, weakness, instability, and repeated episodes of "giving way".

Exclusion criteria

• presence of any current lower extremity injury (diagnosed by a medical professional within last 3 months with present symptoms), previous surgery to either leg, diagnosed ankle sprain within the past 6 weeks, history of ankle fractures and/or dislocations.

Trial design

Primary purpose: Prevention

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

43 participants in 4 patient groups

Control Group

No Intervention group

Description:

Each patient in the control group did not perform any rehabilitation exercises. Over the intervention time frame, the patient was required to check in with a member of the research team each week to discuss any changes in their ankle or report any injury incidence.

Resistance Band Group

Experimental group

Description:

Each session, patients completed resistance training using a resistance band in 4 directions of ankle motion (plantarflexion, dorsiflexion, inversion and eversion). Patients would complete 3 sets of 10 repetitions during each session. Every 3 sessions, the band resistance would increase.

Treatment:

Other: Resistance Band Ankle Rehabilitation

Biomechanical Ankle Platform System

Experimental group

Description:

The Biomechanical Ankle Platform System board is an oval shaped board that utilizes a half-sphere on the bottom of the board to allow the patient to train on an unstable surface. A one legged stance on their involved limb was performed on the Biomechanical Ankle Platform System board while clockwise and counterclockwise circles were completed. The initial rotation of direction was selected by the patient and changed every 10 seconds of the 40-second trial. Five 40-second trials were completed with 1-minute rest intervals in between the trials. Progression was determined by the supervising clinician and was based on the patient's ability to make smooth transitions between direction changes and completion of smooth circular rotations in both directions.

Treatment:

Other: Biomechanical Ankle Platform System Rehabilitation

Combination Group

Experimental group

Description:

Patients completing the combination protocol completed both the resistance band and Biomechanical Ankle Platform System board protocols during each session. The order of exercise completion was counterbalanced for each session.

Treatment:

Other: Combination Rehabilitation
