Comparative Effectiveness Research of Electroacupuncture and TENS in Patients With Rheumatoid Arthritis

Not Applicable

Recruiting

• Conditions: Arthritis, Rheumatoid
• Interventions: Device: electroacupuncture; Device: TENS

• Registration Number: NCT04521998
• Lead Sponsor: China Medical University Hospital

Brief Summary

The aim of this pilot study is to compare the effectiveness of electroacupuncture or transcutaneous electrical nerve stimulation in reducing the tenderness in the patients with rheumatoid arthritis. The study adopted a pragmatic, randomized, patient-centered approach to investigate the effectiveness of clinical symptoms and quality of life.

Detailed Description

A total of 80 volunteers of patients with rheumatoid arthritis will be recruited from the Chinese medicine or Western medicine clinics in China Medical University Hospital and Dalin Tzu-Chi Hospital. These patients will be randomized to receive electroacupuncture (40 participants) or transcutaneous electrical nerve stimulation (40 participants) treatment two sessions per week and for 10 treatments in total.

The investigators expect that electroacupuncture or transcutaneous electrical nerve stimulation can reduce the severity of pain in the patients with rheumatoid arthritis. The effectiveness of electroacupuncture or transcutaneous electrical nerve stimulation can be detected by visual analogue scale, simplified disease activity index, and disease activity score and be used to improve the clinical symptoms and quality of life.

Arm && Interventions

Group	Intervention	Description
electroacupuncture	electroacupuncture	The needles remained in situ for 30 minutes, during which time the acupuncturist returned to stimulate the needles once to re-elicit the de qi sensation. Participants have 2 sessions per week, with total 5 weeks and 10 sessions. The body points included LI4, LI11, SP6 and ST36. The individual specific points protocol are as follows: GB20, TE5, SP10, GB34, LV3, ba xie, ba fen, Ashi). The acupuncture protocol consists of the body points and some of the individual specific points depending on subjects' condition.
Transcutaneous electrical nerve stimulation	TENS	The protocol consisted of first swabbing all points with alcohol, then pads of TENS were sticked on the proper location of acupoints included LI4, LI11, SP6 and ST36. Electrical output of one channel was administered to the surface of body via a combination of two pads. LI4 and LI11, ST36 and SP6 are combination of acupoints, respectively. Participants had 2 sessions per week, with total 5 weeks and 10 sessions. Each session lasted 30 minutes.
