Brief Summary

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

To investigate the effect of early WBVT on neuromuscular control after ACLR.

Detailed Description

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

The knee joint position sense, postural control, muscular strength and functional ability after anterior cruciate ligament construction (ACLR) are distorted, and even after a period of rehabilitation.

Previous studies had demonstrated that there was improvement in knee joint, postural balance, muscle strength and functional outcome in elderly, stroke and spastic patients already. It has also been concluded that the balance in elderly, postmenopausal women, Parkinson's disease, multiple sclerosis, stroke and spastic patients were all significantly improved. Some studies showed that the proprioception in osteoarthritis patients significantly improve. Knee strength is also one of the aspect being improved.

However, no studies focus on the early effect of WBVT on knee joint proprioception, postural control, muscle strength, knee joint stability and functional ability in ACLR cases. This study is to answer this research gap.

Whole body vibration therapy

Whole body vibration therapy on top of conventional physiotherapy treatment.

Group Type EXPERIMENTAL

Whole body vibration therapy

Intervention Type OTHER

The WBVT will be carried out in a vibration plates operated in vertical direction. The frequency of that vibration can be adjusted step of 5Hz with vibration frequency ranges from 20Hz to 60Hz. The amplitude can be set as 4mm.

Control

Conventional post-operative physical therapy rehabilitation exercises.
