Summary
This study developed a 12-week rehabilitation program for soccer players with chronic ankle instability, significantly improving muscle strength and reducing pain. Further research is needed for complex functional improvements.
Area of Science:
- Sports Medicine
- Rehabilitation Science
- Orthopedics
Background:
- Ankle injuries are common in athletes, particularly soccer players, leading to chronic pain and impaired motor function.
- Repeated ankle injuries can result in chronic ankle instability, affecting athletic performance and quality of life.
Purpose of the Study:
- To develop and evaluate an integrated rehabilitation exercise program for preventing chronic pain and enhancing motor ability in athletes with ankle injuries.
- To address the need for effective interventions for chronic ankle instability in male soccer players.
Main Methods:
- A 12-week rehabilitation program focusing on ankle muscle strength and lower limb dynamic coordination was implemented.
- Twenty-six male soccer players with recurrent ankle injuries participated.
- Evaluations included the Y Balance Test and isokinetic strength measurements of ankle movements (dorsiflexion, plantarflexion, inversion, eversion) pre- and post-intervention.
Main Results:
- Statistically significant improvements were observed in the left ankle's dorsiflexor to plantarflexor strength ratio, and in eversion and inversion strength after 12 weeks.
- No significant changes were noted in other measured variables.
Conclusions:
- The integrated rehabilitation program effectively reduced pain and restored joint range of motion, muscle strength, endurance, and functional ability in athletes with chronic ankle instability.
- The findings suggest the program's efficacy in managing chronic ankle instability.
- Development of active protocols targeting complex functions is recommended to further enhance outcomes.
