Brief 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.

Conditions

Chronic Ankle Instability, CAI

Keywords

postural control; chronic ankle instability; talar tilt; tibiotalar contact ratio

Outcome Measures

Primary Outcomes (1)

• Y- balance test

  It is a dynamic balance test that assesses an individual's ability to maintain balance while reaching in three directions (anterior, posteromedial, and posterolateral) with one leg while standing on the other.

  baseline

Secondary Outcomes (1)

• Radiographic measurements validated for non weight bearing radiographs (Talocrural Angle and Talar Tilt)

  baseline

Eligibility Criteria

• Age: 18 Years - 30 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

50 participants, with age between 18- 30 years, diagnosed with unilateral CAI will be recruited through direct referrals based on their availability to participate, thus, a sample of convenience will be used.

You may qualify if:

• At least one significant unilateral lateral ankle sprain in which the subject was unable to walk independently without the aid of crutches (the first sprain occurred more than 12 months ago).
• Feeling of ankle instability "giving way", at least 2 episodes in the last 6 months (Terada et al., 2014).
• Pain during intense loading.
• The Cumberland Ankle Instability Tool (CAIT) ≤ 24.
• Age range of 18-30 years (Delahunt et al., 2010).

You may not qualify if:

• A previous trauma or surgery to the trunk or lower extremities other than an ankle sprain.
• Neurological or vestibular impairments with remaining deficits.
• No participant with CAI had acutely sprained his or her ankle in the 3 months prior to the testing.
• Participants will be excluded if they have participated in any rehabilitation in the past 6 months.
• Concussion or head injury or lower back pain in the past 6 months.
