The Effect of Chronic Pain Relief Over Knee Joint Area by Gua Sha Therapy

Status Recruiting

Clinical Trial Summary

Objective:

A randomized, single-blind, controlled clinical trial is conducted to evaluate the effect of gua sha on the relief of chronic knee joint area pain, and to investigate the association between local skin surface and core temperature changes with chronic pain relief over knee after gua sha. Also, we want to observe the changes before and after gua sha in the local tissues of the knee joint area. We expect to provide more insights into the relevant mechanism of gua sha and relieving pain in chronic knee joint area and establish a complementary therapy for chronic knee joint pain.

Materials and Methods:

In this study, a total of 40 chronic knee joint pain participants will be recruited in the eligible conditions. After agreeing into the clinical study and signing the informed consent form, they will be randomized assigned into the treatment group (20 persons) and control group (20 people). Both groups will be tested for total of 12 days. For treatment group, 2 times of gua sha method will be applied within 12-day test period, the treatments will be on the first day and the fourth day respectively. The control group will be applied 2 times of hot pack method at same period intervals during the 12 days. Both groups will be measured the surface and core temperature of the applied site before and after each method. The visual analog scale (VAS) and the lower extremity functional scale (LEFS) and SF-12 quality of life questionnaire will be performed before and after the test. Ultrasound scans of knee will be performed before and after the test. After the data collection is completed, the analysis is performed in SPSS version 24. Student's t-test and one-way ANOVA methods will be used, with P<0.05 as a significant result.

Expected results:

To establish the positive effect of gua sha therapy to relieve the chronic knee joint pain, and use data and images to infer the mechanism of gua sha therapy on relieving chronic knee joint pain.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
