Brief Summary

This study attempted to:

1. 1.Investigate the difference in calf muscle strength (concentric and eccentric) between affected limb with instability and non-affected limb.
2. 2.Assess the relationship between the severity of ankle instability and calf muscle strength (concentric and eccentric) at velocity (60 and 120◦/s) in patients with functional ankle instability?
3. 3.Investigate the relationship between calf muscle strength (concentric and eccentric) deficit and functional performance in functional ankle instability.

Study Arms (2)

1

Group A (Experimental): 34 affected ankles of both genders diagnosed with functional ankle instability (FAI) who met the inclusion criteria. Their ages ranged from 18 to 25 years, and the patients had a history of initial injury, ongoing bouts of instability, and ratings of patient-perceived function and disability.

Diagnostic Test: y balance and SLS

Group B (Control): This group consisted of 34 matched non-affected ankles in the study.

Diagnostic Test: y balance and SLS

Interventions

y balance and SLS DIAGNOSTIC_TEST

for assessment of static and dynamic balance

Also known as: side hop
