Pain relief is reported to be the most common clinical application of electromagnetic millimetre waves.
To evaluate safety and pain relief effect of millimetre wave therapy (MWT) for treatment of chronic joint pain in a group of patients with diffuse connective tissue diseases.
Twelve patients with diffuse connective tissue diseases received MWT in addition to their analgesic medication with non-steroidal anti-inflammatory drugs. MWT procedure included the exposure of tender points around the painful joints to electromagnetic waves with frequency 54-78GHz and power density of 2.5mW/cm(2). The time of exposure was 35 +/-5 min and the total number of sessions ranged from 5 to 10 (median 6). Intensity of pain, medication requirement, joint stiffness and subjective assessment of therapy success were measured before, during and immediately after the treatment, and after a 6-months follow-up.
No adverse effects of MWT were noted. Pain intensity and required medication decreased significantly after the treatment (p<0.05) and remained at the same level throughout the follow-up period. The joint stiffness decreased and the subjective assessment of the treatment success after 6 month did not change except in only one patient.
MWT applied to tender points around the affected joints was safe under the conditions of our study and after an appropriate full-scale double-blind clinical study, may be recommended as an effective adjunct therapy for chronic pain treatment in patients with diffuse connective tissue diseases.
