Objective: To investigate the effect of the electromagnetic field therapy for patients with myofascial pain syndrome.
Method: The subjects were 53 volunteers diagnosed as myofascial pain syndrome with trigger points in trapezius or quadratus lumborum muscles. The subjects were divided into two groups randomly; experimental (n=30) and control (n=23) groups. Control group received a conventional electrical heat therapy only, while experimental group received additional electromagnetic therapy (IMPERIAL21®, Korea). Treatment was applied for 30 minutes per session and total 10 sessions were carried out for 2 weeks. The effects of treatment were assessed by visual analogue scale, pressure threshold obtained by pressure algometer (Pain Diagnostics and Thermography, USA) and skin temperature of trigger points with infrared thermograph (THERMOVISION400® , Sweden) at pretreatment, after 5th session and after 10th session, respectively.
Results: 1) In both groups, VAS score was significantly decreased after 10th session compared to pretreatment scale (p＜0.05), and VAS score after 10th session showed significant reduction in experimental group as compared with control group (p＜0.05). 2) In both groups, pressure threshold showed significant increase after 10th session compared to pretreatment scale (p＜0.05), and pressure threshold after 10th session was significantly increased in experimental group as compared with control group (p＜0.05). 3) Comparison of the mean skin temperature between two groups across all sessions did not reveal any significant difference. 4) Among the 30 subjects treated with the electromagnetic field therapy, adverse effects, such as headache, dizziness, skin rash and abdominal discomfort, were observed in 5 subjects.
Conclusion: The electromagnetic field therapy might be used as one of the valuable method for pain control in myofascial pain syndrome.
