A Comparative Study of the Acute Effects of Knee Brace vs. Kinesiotape on Selected Isokinetic Strength Variables of the Knee Muscles

Abstract

BACKGROUND: Different methods of treatment for preventing knee injuries, enhancing knee strength and minimising post-injury risks have been explored. Among these methods, Kinesio tape (KT) and knee braces (KB) are commonly used. OBJECTIVE: To investigate the acute effects of KT and KB on isokinetic knee strength parameters. METHODS: A total of 15 healthy sedentary male subjects voluntarily participated in the study. Concentric isokinetic knee extension (EX) and flexion (FLX) strength were measured at three sessions: 1. Baseline 2. with KT ('KT') 3. with KB ('KB'). Tests were performed at 60, 180 and 240 degrees/s. Peak moment (PM), Hamstring/Quadriceps ratio (HQR), and joint angle at peak moment (JAPM) were measured. RESULTS: 'KT' and 'KB' were associated with increase in PMEX, PMFLX, HQR at 60 and 240 degrees/s (p < 0.05) and increased JAPMEX. No significant difference was observed at 180 degrees/s (p > 0.05). CONCLUSION: In healthy individuals, 'I' shape KT and KB positively affect EX and FLX strengths and HQR, especially at low angular velocity.
