Abstract

Background: Following lower limb strength training exercises, patients with stroke often experience muscle fatigue, which can frequently lead to falls. Therefore, this study aims to explore how lower limb muscle fatigue caused by squats affects the strength and balance of healthy individuals before extrapolating it to patients with stroke. Design: Cross-sectional study Methods: The study followed a cross-sectional design. The study was conducted on 30 healthy adults. Strength and balance were measured before and after performing wall squat exercises. Muscle strength was measured using a dynamometer, while balance was assessed with the S3 check system. A paired t-test was used for the analysis. Results: The knee extensor and hip extensor showed a significant decrease after wall squat (p < 0.05). However, there was no significant difference observed in knee flexor and hip abductor between before and after wall squat. Balance did not show a significant difference between before and after wall squat. Conclusion: Muscle fatigue caused by wall squats was found to reduce the strength of the knee and hip extensors, while having no impact on balance. The results of this study may serve as foundational data for future research targeting patients with stroke.
