Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

This is a randomized control trial. Participants will be randomly allocated into either intervention group(vibration training+ conventional rehabilitation program) or control group(conventional rehabilitation program).
Primary Study Purpose

NONE

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Vibration group

Participants in Vibration group will receive an 8-week whole body vibration training in addition to conventional exercise training.

Group Type EXPERIMENTAL

whole body vibration

Intervention Type OTHER

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

Conventional exercise training

Intervention Type OTHER

A set of conventional exercises designed for ACL rehabilitation

Control group

Participants in Vibration group will only receive conventional exercise training.

Group Type ACTIVE_COMPARATOR

Conventional exercise training

Intervention Type OTHER

A set of conventional exercises designed for ACL rehabilitation
