Summary

The purpose of this study is to investigate the association between dynamic postural control and clinical measures of (ankle and hip strength, ankle DFROM and position sense) and radiological measures in patients with unilateral CAI.

Detailed description

Ankle sprains are among the most frequent injuries seen in emergency departments and in sports injury clinics. Among all ankle injuries, ankle sprains are the most common and account for approximately 80% of which 77% are lateral sprains. Ankle sprain incidence ranges from 5.3- 7.0 sprained ankles per one thousand persons per year in Europe and is estimated to be 23,000 ankle sprains occur per day in the United States. Up to 74% of individuals who sprained their ankle experience ongoing problems that prevent them from participating in sports and other physical activities. Lateral ankle sprain (LAS) typically occurs when the rear foot is supinated, and the leg is externally rotated. Inversion injuries affect the lateral ankle ligaments and subtalar ligaments concomitantly; around 73% of lateral ankle sprains are due to rupture or tear of the Anterior Talo-Fibular Ligament (ATFL), followed by Calcaneo Fibular Ligament (CFL) and cervical ligament of the subtalar joint with the interosseous talocalcaneal ligament respectively. HYPOTHESES: It will be hypothesized that: 1. There will be no relation between the radiological measures of the ankle joint and dynamic postural control in patients with unilateral CAI. 2. There will be no relation between hip muscles strength and dynamic postural control in patients with unilateral CAI. 3. There will be no relation between ankle performance (muscle strength, DFROM and position sense) and dynamic postural control in patients with unilateral CAI. 4. There will be a non-significant difference in the dynamic postural control between affected and normal lower limb. 5. There will be a non-significant difference in the radiological measures between affected and normal lower limb. 6. There will be a non-significant difference in the ankle performance between affected and normal lower limb. 7. There will be a non-significant difference in the muscle strength around the hip joint between the affected and normal lower limb.
