Sinew Acupuncture for Knee Osteoarthritis
Sinew Acupuncture for Knee Osteoarthritis (KOA): A Randomized, Sham Controlled, Patient and Assessor Blinded, Pilot Trial
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Objective:
The proposal aims to examine the efficacy and safety of sinew acupuncture for knee osteoarthritis (KOA).
Hypothesis to be tested:
Sinew acupuncture can reduce pain intensity, and improve knee function and health-related quality of life without significant side effects for KOA subjects compared to a sham acupuncture.
Design:
A randomized, subject- and assessor-blind, sham acupuncture-controlled clinical trial
Participants:
Subjects (N=86) will be randomized into sinew acupuncture or sham acupuncture group (in 1:1 ratio).
Study instrument:
Visual Analog Scale (VAS), Western Ontario and McMasters University Osteoarthritis Index (WOMAC), Timed up & Go Test (TUG), 8-step Stair Climb Test (SCT) assessment, and the Short Form-36 (SF-36).
Intervention:
Sinew acupuncture group will receive 10 sessions of needling in 4 weeks. Sham group will receive the non-invasive intervention with the same procedures. All subjects are followed up for 6 weeks.
Main outcome measures:
VAS for knee pain intensity at week 4 serves as the primary outcome. VAS at other time points, WOMAC score, TUG, SCT and SF-36 will be analyzed as the secondary outcomes.
Data analysis:
Analysis will be on the 'intention to treat' principle. T-test and mixed-effect model analysis will be used to measure primary and secondary outcomes respectively.
Expected results:
Sinew acupuncture treatment can significantly reduce knee pain intensity, and improve knee function and quality of life without obvious side effects.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Sinew acupuncture
Subject in the arm will receive real acupuncture intervention.
|
Sinew acupuncture: subject will sit on chair with knee joint flexion with a most comfortable angle nearest to 90 degrees.
Acupoints (1-2cm away from the point of tenderness or pain) near the knee will be punctured through the skin by using sterile needles of size 0.30mm × 40mm at the angle of 0-10 degrees pointing along the pain direction and meridian sinew.
Immediately, needles will be retreated back just under the skin and inserted 10mm-20mm forward smoothly with minimal pain sensation.
Walking and stepping will be advised and governed during acupuncture.
The acupoint will be covered with non-allergic bandages to ensure sufficient blinding to the subject.
The treatment will last 20 minutes for each session.
|
Sham Comparator: Sham acupuncture
Subject in the arm will receive sham acupuncture intervention.
|
Sham acupuncture: subject will receive the same procedures as the sinew acupuncture without penetrating the skin.
The needle will be used to puncture on the acupoint slightly without passing through the skin.
The acupoint will be covered with non-allergic bandages to ensure sufficient blinding to the subject.
