Brief Summary:
To investigate the efficacy and safety according to the frequency of focused ESWT in patients with myofascial pain syndrome.

Condition or disease Intervention/treatment Phase
Myofascial Pain Syndrome Device: Extracorporeal shockwave therapy Not Applicable

Detailed Description:
Myofascial pain syndrome is one of the common causes of musculoskeletal pain seen in clinical practice and is characterized by the presence of trigger points associated with sensitive areas such as taut bands of skeletal muscle. It may also be accompanied by referred pain, which is pain in other parts of the body. Although the pathophysiology and etiology of myofascial pain syndrome and trigger points are still unknown, there are reports that myofascial pain is a complex form of neuromuscular dysfunction caused by motor and sensory abnormalities involving both the peripheral nervous system and the central nervous system. Recently, it has been considered as a method of treatment for myofascial pain syndrome. In addition, although pain reduction and functional improvement of focused ESWT in patients with myofascial pain syndrome have been reported, related studies are lacking on the effect of focused ESWT according to the frequency difference. The purpose of the study is to examine the efficacy and safety of focused type ESWT frequency in patients with myofascial pain syndrome.

Arm Intervention/treatment
Experimental: A (4Hz)
ESWT frequency 4Hz washout period: 1 week
Device: Extracorporeal shockwave therapy
Treatment Location: Painful Area Treatment intensity: 2000 pulses, low energy (0.08~0.28 mJ/m2) the degree to which the subject can tolerate

Experimental: B (8Hz)
ESWT frequency 8Hz washout period: 1 week

Treatment Location: Painful Area Treatment intensity: 2000 pulses, low energy (0.08~0.28 mJ/m2) the degree to which the subject can tolerate




Primary Outcome Measures :
  1. Change from baseline NRS (numerical rating scale) at each time frame [ Time Frame: baseline, immediately after primary treatment, 1 day after primary treatment, 3 day after primary treatment, immediately after secondary treatment, 1 day after secondary treatment, 3 day after secondary treatment ]
    Pain intensity (0-10, ordinal scale)


Secondary Outcome Measures :
  1. Number of treatment-related adverse events as assessed by CTCAE v4.0 at each time frame [ Time Frame: immediately after primary treatment, 1 day after primary treatment, 3 day after primary treatment, immediately after secondary treatment, 1 day after secondary treatment, 3 day after secondary treatment ]
