Lower Extremity Mobility for CAI

NCT07584746 | Not Yet Recruiting

• 1 other identifier: Mobility training for CAI
• Study Type: interventional
• Target: 40
• Locations: 0 countries
• Sites: N/A

Brief Summary

This study will be conducted to determine the effect of addition of ankle mobility versus hip mobility exercises to traditional rehabilitation to patients with chronic ankle instability. the main purpose is to answer the following question:

• out of these interventions which would better improve lower limb flexibility, range of motion, severity of functional instability and dynamic postural control? Researcher will compare between ankle mobility versus hip mobility exercises Participants will be allocated in 2 experimental groups:
• group A will include 20 patients receiving conventional physiotherapy in addition to ankle mobility exercises
• group B will include 20 patients receiving conventional physiotherapy in addition to hip mobility exercises Patients will receive 3 sessions per week for 6 weeks in a physiotherapy outpatient facility for both groups

Conditions

Chronic Ankle Instability, CAI

Outcome Measures

Primary Outcomes (4)

• lower limb flexibility

  measure the lower trunk and lower extremity flexibility with modified sit and reach test, sideways split and single legged knee bend test

  6 weeks

• Range of motion

  Hip flexion and extension range of motion Ankle dorsiflexion and plantarflexion range of motion

  6 weeks

• severity of chronic ankle instability

  using the Arabic version of the Cumberland Ankle Instability Tool, a tool used to describe the severity of chronic ankle instability, with the highest possible score is: 30 and the lowest possible score is: 0 Higher scores indicate better ankle stability, while lower scores indicate higher severity of functional instability

  6 weeks

• Dynamic postural control

  using the modified star excursion balance test

  6 weeks

Study Arms (2)

Group A

EXPERIMENTAL

20 patients (10 males and 10 females) will receive ankle mobility exercises and traditional physiotherapy program

Other: traditional rehabilitation for Chronic Ankle Instability; Other: Ankle mobility exercises

Group B

EXPERIMENTAL

20 patients (10 males and 10 females) will receive hip mobility exercises and traditional physiotherapy program

Other: traditional rehabilitation for Chronic Ankle Instability; Other: Hip mobility exercises

Interventions

traditional rehabilitation for Chronic Ankle Instability OTHER

* Ankle muscles strengthening exercises * balance training

Group A; Group B

Ankle mobility exercises OTHER

9 ankle mobility exercises including: ankle pumps, ankle circles, forward lunges, plantarflexion stretch, calf stretch, squat with overhead reach, heel drops on step, ankle flexion with band and scoops

Group A

Hip mobility exercises OTHER

8 hip mobility exercises including: 90/90 hip stretch, frog stretch, world's greatest stretch, banded hamstring stretch, backward lunges, butterfly, pigeon stretch and banded hip stretch.

Group B

Eligibility Criteria

• Age: 18 Years - 30 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Adults (18-30 years old) with chronic ankle instability
• Patient's Body mass index (BMI) will range from 18.5- 29.9 kg/m2
• A history of at least one ankle sprain with the initial sprain occurring 12 months prior to study
• Most recent injury 3 months prior to start of treatment with at least one day of interrupted desired physical activity and associated inflammatory symptoms (pain, swelling, etc.).
• A history of previous giving way and/or recurrent sprain, and/or feeling of instability to injured ankle.
• Cumberland Ankle Instability Tool: score of ≤ 24.

You may not qualify if:

• Other lower extremity injury surgery 6 months before testing
• Patient suffered an acute sprain in the previous 6 weeks to the start of the study.
• History of neuromuscular disorders.
• Systemic diseases that affect balance.
