Effects of proprioceptive versus conventional exercises on balance and lower extremity functions in individuals with ankle instability in ankle sprain

Abstract

Background: Sprains constitute 85% of ankle injuries. Despite the high prevalence, these are often regarded as injuries that will resolve on their own and therefore many people do not seek treatment, resulting in functional and/or chronic instability and/or residual ankle instability. A study is needed so recurrence of ankle sprains can be prevented. Methods: Prospective, comparative study design with convenient sampling. Patients diagnosed with grade 2 ankle sprain were taken. They were assessed using the Star Excursion Balance Test for ankle instability and balance, Lower Extremity Functional Scale for functional mobility, Visual Analog Scale for pain and Modified Oxford Scale for muscle strength. The experimental group (n = 09) received both proprioceptive and conventional exercises. The control group (n = 09) received only conventional exercises. Patients were assessed at the baseline and at the end of 4th week for balance, functional mobility, pain and muscle strength. Results: Post intervention, balance improved on SEBT score significantly (p = 0.01) more in experimental than in control group. Difference between both the groups was statistically significant (p = 0.02) for LEFS score. Pain reduced significantly (p = 0.02) on VAS score in experimental than in control group. Muscle strength improved significantly (p = 0.00) more in the experimental than in control group. Conclusion: Proprioceptive exercises along with conventional occupational therapy exercises in ankle sprain are effective in improving balance, lower extremity functions, muscle strength.
