AB  - OBJECTIVE: To determine the differences between clinical effects of 
      electroacupuncture and biofeedback therapy in addition to conventional treatment 
      in patients with cervical myofascial pain syndrome (MPS). DESIGN: Randomized 
      clinical trial. SETTING: Physical medicine and rehabilitation clinic of a 
      university hospital. PARTICIPANTS: Fifty patients (N=50) aged 25-55 years of both 
      sexes with chronic neck pain diagnosed with MPS (characterized by trigger points 
      within taut bands) were randomly assigned to 2 equal groups of 25 individuals. 
      INTERVENTIONS: The patients in electroacupuncture group were treated with 
      standard acupuncture and concomitant electrical stimulation; those in biofeedback 
      group received visual electromyography biofeedback therapy for muscle activity 
      and relaxation. Both groups received the intervention 2 times a week for a total 
      of 6 sessions. Basic exercise training and medicines were administered for all 
      the patients. MAIN OUTCOME MEASURES: Pain severity based on the visual analog 
      scale (VAS), functional status using Neck Disability Index (NDI), cervical range 
      of motion (ROM) using and inclinometer, and pressure pain threshold (PPT) using 
      an algometer were evaluated before and at 3 and 12 weeks after the treatment. 
      Primary outcome was defined as 20% reduction in the 3-month neck pain and 
      dysfunction compared to baseline, assessed through the NDI. RESULTS: Fifty 
      patients (39 women, 11 men) with a mean age (years) +/- SD of 39.0+/-5.5 and neck 
      pain duration (weeks) of 6.0+/-2.2 were analyzed. All parameters, except for PPT of 
      the lower trapezius and paravertebral muscles were improved significantly in both 
      groups, while baseline values were controlled. The primary outcome was achieved 
      more significantly in the acupuncture group than in the biofeedback group: 20 
      (80.0%) vs 10 (40.0%); rate ratio=2 with 95% confidence interval (CI), 1.19-3.36; 
      number needed to treat (NNT)=2.5 with 95% CI, 1.54-6.58. Advantages of 
      acupuncture over biofeedback were observed according to values obtained from the 
      NDI, VAS, extension and left lateral-bending ROM, and PPT on the left upper 
      trapezius after the last session of intervention until 3 months (P<.05). 
      CONCLUSIONS: Both electroacupuncture and biofeedback therapies were found to be 
      effective in management of MPS when integrated with conventional treatment. 
      However, intergroup differences showed priority of acupuncture in some parameters 
      vs biofeedback. Thus, electroacupuncture seems to be a better complementary 
      modality for treatment of MPS in the neck and upper back area.
