Clinical Trial Summary

This study protocol is mainly focus on the patients, who suffer pain, swelling, or range of motion limitation after total knee replacement (TKR) surgery procedure,would be relieved by use non-invasive laser acupuncture to stimuli on 1) the reflection areas of ear acupuncture point associated knee and pain mechanism; 2) muscle trigger points around knee joint with adequate frequency and energy power to stimuli.

Description:

Traditional Chinese acupuncture has a history of several thousand years. The World Health Organization has published guidelines describing the efficacy of acupuncture in the cure or relief of 64 different symptoms and conditions as one of the most representative intangible cultural heritage of humanity. However, for the need of patients and the gradual progress of technology, the applications of laser acupuncture become widespread. Laser acupuncture (LA) is not only applicated to stimuli specific areas in need, but also one of non-invasive intervention technic with hurtless intervention, no hematoma, bleeding or swelling unpleasant feeling after intervention, which could be more accepted by children, weakness people, and patients who afraid of acupuncture. To the area that traditional Chinese acupuncture could not stimuli easily of some area reflect to brain precisely, laser acupuncture is comparably convenient to supply adaptive energy input.

The goals of this study protocol is focus on the patients who accept total knee replacement (TKR), who usually suffer pain, swelling, or range of motion limitation after TKR surgery procedure, and the investigators want to use non-invasive LA to stimuli on 1) the reflection areas of ear acupuncture point associated knee and pain mechanism; 2) myofascial trigger points around knee joint, which may affect functional performance and prognosis after TKR procedure, with adequate frequency and energy power to stimuli, to observe the efficacy of LA on pain relief, swelling decline, and range of motion in knee joint improvement. One the one side, the investigators want to shorten the period of recovery, accelerate the function performance, and enhance the quality of life of patients after TKR procedure by LA intervention,on the other side, the investigators also want to confirm the value and curative effect of LA on clinical application and to evoke new idea for further development to traditional Chinese acupuncture.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Changes from Visual Analog Scale for myofascial trigger points	A Visual Analog Scale consists of a line, often 10 cm long, with verbal anchors at either end, on left of line, zero, meant no pain otherwise on right, 10, meant strong pain. The patient places a mark at a point on the line corresponding to the patient's rating of pain intensity.	The 1 day Before the first laser acupuncture and the 1 day after the last laser acupuncture intervention
Primary	Changes from WOMAC scale of Knee (modified in Chinese)	The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation of Knee and other osteoarthritis. This modified version is a self-administered questionnaire consisting into 4 subscales and mainly focus on functional performance: pain and ability to walk, pain and ability to go up and down stairs, knee swelling, and the range of motion of knee flexion.	Baseline (Before surgery), 1 month after surgery, and 3 months after surgery
