  Purpose
Collateral meridian therapy (CMT) is a recently developed technique according to traditional Chinese medicine (TCM) experiences, differing from traditional Chinese acupuncture in numerous manners. CMT involves the manipulation of a distant non-painful collateral meridian, thereby facilitating the dissipation of pain. The technique avoids direct stimulation of the involved meridian, which enhances patient tolerability and prevents further injury to the disease and painful areas. Numerous clinical cases have reported the effectiveness of CMT in pain management. This study tests whether CMT is effective for treating knee OA pain and functional recovery.

Primary Outcome Measures:
  • Western Ontario and McMaster Universities Osteoarthritis Index, visual analogue scale [ Time Frame: 3 months ]
    ain intensity at activity, quantified with a 100 mm VAS and pain disability measured with the Western Ontario and McMasters Universities Osteoarthritis Index. The VAS and WOMAC scores were measured immediately by independent staff before the first treatment, and subsequently at one, two, three weeks, and three months after the first treatment.


Enrollment: 28
Study Start Date: March 2011
Study Completion Date: December 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Collateral Meridian Therapy
The CMT group patients received, according to the CMT protocol described previously, CMT at the selected points with the CMT Electrotherapy Stimulator ("GEMORE" Multi-Function Electrotherapy Stimulator; GM390TE, GEMORE Co Ltd, Taiwan) to treat the affected OA knee. The 6-minute treatment (electrotherapy was set at 40 Hz biphasic and 30 mA) comprises reduction and enhancement procedures on the specific points. Each patient received CMT twice per week for three weeks during the study.
Device: "GEMORE" Multi-Function Electrotherapy Stimulator
The Collateral Meridian Therapy (CMT) group patients received, according to the CMT protocol described previously (5), CMT at the selected points with the CMT Electrotherapy Stimulator ("GEMORE" Multi-Function Electrotherapy Stimulator; GM390TE, GEMORE Co Ltd, Taiwan) to treat the affected OA knee. The 6-minute treatment (electrotherapy was set at 40 Hz biphasic and 30 mA) comprises reduction and enhancement procedures on the specific points. Each patient received CMT twice per week for three weeks during the study.
No Intervention: Control (CT) group
Patients in the CT group received electronic lead-patches applied on the treatment points, which was identical to what the CMT patients received, also for 6 minutes, though no electric stimulation was applied.
