Abstract

Background: This study aimed to investigate the immediate effects of Flexi-bar exercise on plantar pressure and Center of Pressure in a standing position. Design: Single group pre-post test design Methods: Thirty healthy adult participants aged 20 to 35 years old and no recent musculoskeletal injuries were included in this single-group pre-post design study. Plantar pressure and COP data were collected using the WinTrack system before and after Flexi-bar exercise. Participants performed Flexi-bar exercises in both anterior-posterior and lateral directions for 30 seconds each. Results: The results revealed significant changes in plantar pressure and COP after Flexi-bar exercise. The support area of the left foot significantly increased (p<0.05), and a significant decrease in mean pressure was observed in the right foot (p<0.05). The total COP path length and area significantly decreased (p<0.05). Furthermore, there was a significant decrease in COP velocity along the X and Y axes (p<0.05). These findings suggest that Flexi-bar exercise can enhance plantar pressure distribution and COP movement patterns, contributing to improved balance ability. Conclusion: Flexi-bar exercise, performed in a standing position, has the potential to improve plantar pressure and COP characteristics. This exercise may serve as a valuable tool for enhancing balance ability. Further research is needed to explore the long-term effects and sustainability of these improvements.
