简要总结
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
详细描述
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.

结局指标
主要结局
Vertical ground reaction force
时间窗: immediately after intervention, three month after intervention
Peak vertical ground reaction force will be evaluated by a synchronized force plate during single leg hop landing.
knee flexion angle
时间窗: immediately after intervention, three month after intervention
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.
knee valgus angle
时间窗: immediately after intervention, three month after intervention
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.
knee internal rotation angle
时间窗: immediately after intervention, three month after intervention
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.
Knee valgus torque
时间窗: immediately after intervention, three month after intervention
Peak knee valgus torque will be evaluated by a synchronized force plate during single leg hop landing.
Knee extension torque
时间窗: immediately after intervention, three month after intervention
Peak knee extension torque will be evaluated by a synchronized force plate during single leg hop landing.
次要结局
- muscle elasticity(immediately after intervention, three month after intervention)
- muscle strength(immediately after intervention, three month after intervention)
- muscle activation(immediately after intervention, three month after intervention)
