Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Treatment of myofascial pain syndrome includes physical therapy, stretch exercise, dry needle insertion and trigger point injection. Acupuncture originated from ancient Chinese medicine which involves the insertion of fine needle to stimulate specific points of the body along the 12 meridians. The mechanism of pain relief may be initiated by activation of both spinal segmental and supraspinal centers. Acupuncture is commonly used for pain relief.
Recently, radial shock wave has been shown to be effective in the treatment of chronic musculoskeletal pain, including calcific tendinitis, epicondylitis, and plantar fasciitis. The energy and pressure produced by radial shock wave is focused on the treated musculoskeletal tissue. The mechanism of action has been hypothesized that the energy could result in analgesic effect and stimulation of angiogenesis and healing response and then relief of the symptoms. The effectiveness of radial shock wave on treatment of myofascial pain was reported by Jeon and colleagues in 2012.
The aim of this study is to compare the efficacy of acupuncture and radial shock wave therapy in patients with myofascial pain syndrome.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The patients will be randomized to either treatment groups: group 1, radial extracorporeal shock wave therapy (RSWT group) and group 2, acupuncture group (AC group).
All treatments will be given in the Department of Physical Medicine and Rehabilitation, and will be handled by a physiatrist who is familiar with both kinds of therapy.
The RSWT is delivered at 2 Hz with 2000 shock waves and the energy level of 0.056 mJ / mm2 in the trapezius muscle. Treatment point is the origin attachment of upper trapezius at the external occipital protuberance. RSWT will be performed once per week, and will be continued for 3 weeks.
Acupuncture is performed at Fenfchi (GB20) point over upper back. This acupoint is a common local point for treating upper back pain. Acupuncture therapy will be provided by the same physiatrist to all patients.
The primary outcome measures are VAS for pain and pain threshold. The secondary outcome measures are neck disability index, and patients' satisfaction. All subjects will be assessed by an independent, blinded investigator at baseline, post treatment and at 1-month after the treatments are completed.
Demographic data, including age, sex, employment status, and sleep quality, history of head or neck surgery, or other psychiatric and medical disorders will be recorded at baseline. A history will be taken concerning the duration of complaints (months), previous treatments (injections, physical therapy), and current pain medications. Concomitant diseases and the use of medications will be registered.

Radial shock wave, Acupuncture
Radial shock wave: 2 Hz with 2000 shock waves, and the energy level of 0.056mJ/mm2 in the trapezius muscle. It will be done once per week for 3 weeks.
Acupuncture: performed at Fenfchi (GB20) point over upper back. It will be performed once per week for 3 weeks .
Radial shock wave
radial shock wave: Treatment point is the origin attachment of upper trapezius at the external occipital protuberance. Radial shock wave therapy will be performed once per week, and will be continued for 3 weeks. Acetaminophen will be prescribed as rescue medication, and the amount given will be recorded at the end of the study.
