Abstract

Although superficial heat therapy is most often used as a physical therapy for treating low back pain (LBP), it has a disadvantage that it has a great effect of heating the skin and subcutaneous tissue and cannot penetrate deep tissue. Deep heat treat-ments such as microwave diathermy (MWD) are more effective in order to penetrate deep into the muscles and have a relaxing effect on the tissues (1). MWD uses electromagnetic energy to increase the kinetic energy of molecules and convert it into thermal energy to generate deep heat (2). MWD does not stimulate sensory and motor nerves due to its short pulsation period, and there is no risk of electrolyte burns (3). Despite the many benefits of MWD, few studies have specifically investi-gated the effects of MWD combined with exercise therapy. Therefore, this study was conducted to investigate the effect of MWD combined with trunk balance exercise on pain and function in chronic LBP pa-tients. Subjects were 20 outpatients with chronic LBP, and were randomly assigned to the experimental group (MWD + trunk balance exercise) (n = 10) or control group (sham MWD + trunk balance ex-ercise) (n = 10). The therapeutic dose of MWD in this study was an intermediate dose (80W) and was performed for 20 min at a time, 3 times a week, and for 6 weeks. It was applied without turning on the mi-crowave for the sham treatment, but the patients received it in a prone position, and the MWD have little sense of treatment, so they did not notice the sham treatment. The trunk balance exercise performed by the sub-jects included hip extension by lifting the pelvis in a supine position, quadruped position with one arm and the opposite leg extension, and balancing by lifting both feet off the floor with only one hip on the table. The trunk balance exercise was per-formed for 15 min immediately after MWD. Differences in general characteristics between the experimental group and the control group before intervention were compared using the Mann-Whitney tests and chi-square tests. The Wilcoxon signed-rank tests were performed to assess the be-fore and after effects in each group. The Mann-Whitney tests were used to assess differences be-tween real MWD and sham MWD. For all anal-yses, P values <0. 05 were considered significant and statistical analysis was performed using SPSS version 20. 0 (IBM Corp., Armonk, NY, USA). . .
