Intervention model description: Backward Walking Training and Balance Training
Primary purpose: TREATMENT

Brief summary: The goal of this clinical trial is to investigate the effect of backward walking versus balance training in patients with chronic ankle instability. The main question it aims to answer is:

Is there a difference between the effect of balance training and BW training on balance, ankle proprioception, risk of fall, and functional limitations in CAI patients?

Detailed description: Lateral ankle sprains are among the most common musculoskeletal injuries. Approximately 40% of individuals who have ever suffered any lateral ankle sprain will develop chronic ankle instability which is defined as posterior mechanical and functional deficits in this joint.

Balance is the process that maintains the center of gravity within the body's support base, which needs constant adjustments with joint positioning and muscular activity. Many musculoskeletal and nervous system diseases can alter balance control. It has been reported that individuals with CAI have poor static and dynamic balance compared to those with normal ankles, and this affection of balance, increases the falling risks and leads to serious injuries.

A reversal of normal walking is simply recognized as retro-walking or backward walking (BW), where the toes first reach the ground and finish with the heel off. BW training causes changes in the motion control system and gait characteristics and exerts a positive effect on postural stability.

Sixty patients with chronic ankle instability will be assigned randomly into 3 equal groups; group A will receive BW training in addition to the traditional physical therapy program for 3 sessions/ week, over 6 weeks periods, Group B: will receive balance training on Biodex balance system in addition to the traditional physical therapy program for 3 sessions/ week, over 6 weeks periods, group C: will receive the traditional physical therapy program only for 3 sessions/ week, over 6 weeks periods.

Eligibility criteria: Inclusion Criteria:

1. All subjects will complete a questionnaire by self-report (Cumberland Ankle Instability Tool (CAIT) to be characterized as having Functional Ankle Instability (FAI) ; All subjects' scores on CAIT will be less than 23 to be severely identified with FAI. Subjects will satisfy the following criteria:

   Having FAI that persists after the initial lateral ankle sprain and complaining of residual symptoms (repeated episodes of giving way or feeling of ankle joint instability) and suffering of repeating injury.
2. Having mechanical ankle instability on one ankle joint (will be identified by manual testing as talar tilt and anterior drawer test of the ankle to determine the integrity of ankle ligaments).
3. Their age ranges from 18 to 35 years.
4. Subjects with body mass index less than 30 kg/m2.
5. Not undergoing any formal or informal rehabilitation of the unstable ankle.

Exclusion Criteria:

1. Ankle joint swelling or any rheumatological disorders in both legs.
2. Ankle surgery in either leg.
3. Gross limitation in ankle range of motion in both legs.
4. Any joint disease or bony fracture in the lower extremity.
5. History of neurological disorder affecting the upper or lower extremities, vestibular dysfunction, or balance disorder.
6. Receiving formal or informal rehabilitation of their unstable ankle for 3 months.
