Comparison of Balance Between Badminton and Volleyball Recreational Players with Chronic Ankle Instability: A Cross-sectional Study

Abstract

Introduction: Chronic Ankle Instability (CAI) is an injury that presents persistent instability and “giving way” symptoms. The higher rate of reinjury following an initial Lateral Ankle Sprain (LAS) is associated with the development of CAI, which affects athletic and functional performance. Impairment of musculotendinous receptors following an initial ankle sprain may result in recurrent ankle instability. Some studies have suggested an association between CAI and issues with static and dynamic balance. Comparisons of static balance between recreational badminton and volleyball players and dynamic balance between recreational badminton and volleyball players with CAI are required to provide athletes with the proper balance training exercises. Aim: To analyse the static balance of badminton and volleyball recreational players with CAI using the Balance Error Scoring System (BESS) and a Plantar Pressure Analysis System (PPAS), as well as the dynamic balance of those players using the Y Balance Test (YBT). Materials and Methods: A cross-sectional study was conducted where recreational players with CAI who play badminton and volleyball were screened using the Cumberland Ankle Instability Tool (CAIT), and 46 participants were selected based on inclusion and exclusion criteria. The study was conducted in the indoor and outdoor stadiums of NITTE (Deemed to be University), Mangaluru, Karnataka, India. The study duration was from March 2023 to March 2024. Ethical clearance was obtained from the same university for the study. Following this, static and dynamic balance of each group was assessed using BESS (number of errors), PPAS (sway velocity), and YBT (distance reached by the limb). The static balance between the groups and dynamic balance between the groups were analysed in Jamovi software using independent sample t-test. Results: Following the analysis, static balance between badminton and volleyball recreational players using BESS showed a non significant difference with a p-value of 0.282, while PPAS showed non significant differences with p-values of 0.174 for double leg stance and 0.063 for single leg stance. Similarly, dynamic balance between badminton and volleyball recreational players using YBT showed non significant differences with p-values of 0.467, 0.768, and 0.299 for anterior, posteromedial, and posterolateral directions, respectively. Conclusion: The study concluded that there was no significant difference in static as well as dynamic balance between badminton and volleyball recreational players with CAI. However, it is important to evaluate the static and dynamic balance of recreational players to enhance performance and prevent injuries.
