Comparing the Effectiveness of Wobble Board and Uniaxial Rocker Board Balance Training in Functional Recovery of Subjects with Sub- Acute Grade 2 Inversion Ankle Sprain

Introduction: Ankle sprains, commonly referred to as inversion or supination ankle sprains, occur due to forced plantar flexion or inversion, leading to varying degrees of lateral ligament damage. While generally considered a benign injury, inadequate rehabilitation can result in persistent symptoms, affecting 55% to 72% of patients between 6 weeks to 18 months post-injury. The frequency and duration of these complications have raised concerns regarding optimal treatment strategies for ankle sprains. Aim: This study aims to compare the effectiveness of wobble board and uniaxial rocker board balance training in functional recovery following Grade 2 inversion ankle sprain. Methodology: A total of 40 patients, both male and female, aged between 18-35 years, diagnosed with Grade 2 ankle inversion sprains were assessed using the talar tilt and anterior drawer tests. Patients with negative results on these tests and meeting the inclusion criteria were enrolled in the study. Pre-test and post-test outcome measures, including the Star Excursion Balance Test (SEBT) and the Ankle Joint Functional Assessment Questionnaire (AJFAQ), were used to assess balance and functional recovery. Results: No significant difference (p>0.05) was observed between Group A (wobble board) and Group B (uniaxial rocker board) during the pre-test in SEBT and AJFAQ scores. However, a significant difference (p<0.05) was found between the two groups during the post-test, with Group B showing greater improvement in both balance (SEBT) and functional recovery (AJFAQ) scores compared to Group A (p<0.05). Conclusion: Both the wobble board and uniaxial rocker board are effective tools for balance training and functional recovery in patients with Grade 2 ankle inversion sprain. However, the uniaxial rocker board (Group B) demonstrated superior efficacy in improving postural control and overall recovery compared to the wobble board. These findings underscore the importance of targeted rehabilitation protocols using balance training devices to enhance recovery outcomes after ankle sprain injuries. Major Findings: The uniaxial rocker board was significantly more effective than the wobble board in enhancing balance and functional recovery post Grade 2 ankle inversion sprain.
