Effect of Core Stability Training With Foot Exercises in Chronic Ankle Instability Patients

This study aims to investigate the effects of various treatments on lumbar and ankle proprioception, balance, and foot function in patients with chronic ankle instability. The objectives include assessing the combined effects of core stability training and intrinsic foot muscle exercises with conventional therapy, the impact of core stability training alone, the effects of intrinsic foot muscle exercises in conjunction with conventional treatment, and the outcomes of conventional therapy alone. Additionally, the study will compare the effectiveness of these different treatment protocols.

Inclusion Criteria: Subjects will be selected from the outpatient clinic of Delta University hospital, Dakahlia, Egypt. 2. Both male \& female genders aged between 18 and 44 years. 3. Participants should have a history of at least one significant ankle sprain; the initial sprain must have occurred at least 12 months prior to the study enrolment and was associated with inflammatory symptoms (pain, swelling) 4. Patients having Scores on the Cumberland ankle instability tool of 24 or below 5. Participants should report at least 2 episodes of 'giving way' in the 6 months prior to the study enrolment. Episodes of giving way will be described as an incident in which the rearfoot suddenly rolled, felt weak, or lost stability; however, the individual did not sustain an ankle sprain and will have been able to continue with normal function after the incident 6. Body mass index for all groups will be ranged from 18.8-29 kg/m² Exclusion Criteria: 1. history of lower extremity surgery, lower extremity fractures, and immobilization of foot or ankle for 48 hr or longer within the previous 6 months 2. Conditions other than ankle sprain that affect balance or they are receiving ankle rehabilitation at the time of screening. 3. Acute injury to the musculoskeletal structures of other joints of the lower extremity in the previous 3 months, which impacted joint integrity and function (ie, sprains, fractures) resulting in at least 1 interrupted day of desired physical activity
