Summary

Introduction: Approximately 35% patients can not return to sports after anterior cruciate ligament reconstruction(ACLR). Persistent quadriceps weakness is a factor that prevents patients return to sports. Pre-operative quadriceps strength is a predictor for the outcomes after ACLR. Therefore, enhancing pre-operative quadriceps is important. However, current prehabilitation can not well restore quadriceps strength may be due to quadricep inhibition. Whole body vibration was proposed as a promising intervention to increase muscle strength and modulate quadriceps inhibition simultaneously. Therefore, this study aim to investigate if whole body vibration has the efficacy of enhancing pre-operative quadriceps and modulating quadricep inhibition in patients with ACL injuries.

Methods: A randomized controlled trial was designed. Patients with primary ACL injuries, age from 18-45 yrs, BMI\<29, physically active who awaiting ACLR will be included. Patients with any previous lower-limb injuries within 1 year, any cardiovascular or metabolic disorders will be excluded. All the subjects in this study have to finish their routine 5 week prehabilitation as well as the interventions. The primary outcomes of this study include quadriceps strength and quadriceps central activation ratio. Secondary outcomes include the score of IKDC and ACL-RSI, as well as the concentrations of myokines in serum.
