Osteoarthritis is the most frequently diagnosed disease of the musculoskeletal system. Growing number of patients waiting for surgical treatment and the possible negative consequences resulting from long-term pharmacological therapy lead to the search for non-pharmacological methods aimed at alleviating pain and reducing doses of analgesics, among them physical therapy with use of magnetic fields.The study involved 30 men aged 49 to 76 (mean age, 61.7 years) treated for idiopathic osteoarthritis of the hip joint. The subjects were divided into 2 groups (15 patients each) and underwent a cycle of magnetostimulation and magnetoledtherapy procedures, respectively. During the exposure cycle concentrations of β-endorphin were assessed 3 times and the mood was assessed 2 times. In addition, the assessment of pain intensity and the dose of analgesic drugs was performed before and after the end of therapy.Statistically significant increase in plasma β-endorphins concentration was observed in both groups of patients (magnetostimulation-P < .01 vs magnetoledtherapy-P < .001). In the assessment of mood of respondents, no statistically significant differences were found. Significant reduction in intensity of perceived pain was observed in both groups of patients (P < .05). In the group of patients who underwent magnetoledtherapy cycle, the analgesic drug use was significantly lower by 13% (P < .05) as compared with initial values, which was not noted in group of patients who underwent magnetostimulation procedures.The use of magnetic field therapy in the treatment of men with idiopathic osteoarthritis of hip joints causes a statistically significant increase in the concentration of plasma β-endorphins resulting in statistically significant analgesic effect in both magnetostimulation and magnetoledtherapy treated groups of patients, with accompanying decrease of need for analgetic drugs in magnetoledtherapy group, but without any significant changes regarding the patient's mood.
