An interventional study of whole body vibration and Conventional exercise training in ACL Injury, sponsored by Chinese University of Hong Kong. Recruiting at 1 site in Hong Kong. Open to participants aged 18 Years to 50 Years. Per ClinicalTrials.gov, last updated 2023-08-30.

This is a randomised clinical trial to detect the effect of an 8-week whole body vibration training on muscle function and dynamic knee function during single leg squat and single leg hop in patients after anterior cruciate ligament reconstruction
In Hong Kong, over 3000 cases of ACL reconstruction are operated annually to restore knee stability. Despite recovery of knee passive laxity and muscle strength, dynamic knee stability is often not restored. The whole body vibration has been found to improve muscle strength, proprioception and balance after ACL reconstruction. This project will investigate the effect of whole body vibration on muscle elasticity, muscle coordination and landing knee biomechanics. It may provide useful evidence to the application of whole body vibration in improving dynamic knee stability, which will lead to a significant improvement in healthcare management for ACL patients . The current study serves to provide a clinical guideline for post-ACL reconstruction rehabilitation.

Exclusion Criteria:
Participants in Vibration group will receive an 8-week whole body vibration training in addition to conventional exercise training.
Other: whole body vibration · Other: Conventional exercise training
Participants in Vibration group will only receive conventional exercise training.
Other: Conventional exercise training
The whole body vibration is used when vibrations (mechanical oscillations) of a certain frequency are transferred to the human body. Humans are exposed to vibration through a contact surface that is in a mechanical vibrating state. It has been considered as an alternative and safe method for neuromuscular training and may be incorporated into current neuromuscular rehabilitation programs so as to enhance muscle recovery
A set of conventional exercises designed for ACL rehabilitation
knee flexion angle
Peak value of knee flexion will be assessed by the skin marker-based motion analysis system (Vicon MX, Oxford, UK) during single leg squat and single leg hop landing.
Time frame: immediately after intervention, three month after intervention
knee valgus angle
Peak value of knee valgus will be assessed by the skin marker-based motion analysis system (Vicon MX, Oxford, UK) during single leg squat and single leg hop landing.
Time frame: immediately after intervention, three month after intervention
knee internal rotation angle
Peak value of knee internal rotation will be assessed by the skin marker-based motion analysis system (Vicon MX, Oxford, UK) during single leg squat and single leg hop landing.
Time frame: immediately after intervention, three month after intervention
Vertical ground reaction force
Peak vertical ground reaction force will be evaluated by a synchronized force plate during single leg hop landing.
Time frame: immediately after intervention, three month after intervention
Knee valgus torque
Peak knee valgus torque will be evaluated by a synchronized force plate during single leg hop landing.
Time frame: immediately after intervention, three month after intervention
Knee extension torque
Peak knee extension torque will be evaluated by a synchronized force plate during single leg hop landing.
Time frame: immediately after intervention, three month after intervention
muscle strength
Isometric muscle strength of quadriceps and hamstring will be tested using an hand-held dynamometer. The isokinetic muscle strength of quadriceps and hamstring will be tested at 60°/s and 180°/s by the isokinetic dynamometer
Time frame: immediately after intervention, three month after intervention
muscle elasticity
Shear elastic modulus of vastus medialis, vastus lateralis, semimembranosus and biceps femoris will be assessed by shear wave elastography ultrasound.
Time frame: immediately after intervention, three month after intervention
muscle activation
Muscle activity level of vastus lateralis, vastus medialis, biceps femoris and semitendinosus will be assessed by electromyography
Time frame: immediately after intervention, three month after intervention
