The aim of our study was to test the influence of magnetic fields during magnetotherapy and magnetostimulation over a longer period of time (like in physiotherapy) on cortisol secretion in humans. The study population was divided into two groups: magnetotherapy group (16 men) and magnetostimulation group (10 men). Magnetotherapy in the form of magnetic field induction (2.9 microT; frequency--40 Hz; square wave; bipolar; Magnetronic MF--10 apparatus) was applied for 20 min to the lumbar area in patients with chronic low back pain. Magnetostimulation (Viofor JPS system; M2P2 program; induction--25-80 microT; frequency--200 Hz, complex saw-like shape with a plateau halfway the height of the wave; bipolar) was applied every day for 12 min in patients with the same health problem. In both groups, the procedures were repeated 15 times (about 10:00 a.m.) with weekend breaks. Serum samples were collected at 6:00, 12:00, 16:00 and 24:00 and estimated by the micromethod of chemiluminescence (DPC Poland; Cat. No. LKC01). The circadian profile of cortisol was determined prior to the application, a day and a month after application. The data were analyzed statistically, using paired and unpaired Student's test. Magnetotherapy affects the cortisol secretion in the circadian profile by decreasing its level at 16:00 a day after 15 applications, whereas magnetostimulation by increasing its level at 12:00 a month after 15 applications, which may suggest its long-term effect on hypothalamic-pituitary axis. The comparison of the results indicated that a day after magnetotherapy and magnetostimulation, the circadian curves of cortisol secretion differed significantly by about 100%. All hormone oscillations did not exceed the physiological norms of the circadian cortisol level, not reaching the level so high as in an intense stress. This suggests rather their controlling effect on the cortisol level than their significant stressogenic nature.
我们研究的目的是测试在磁疗和磁刺激过程中，较长时间段（如在物理治疗中）磁场对人体皮质醇分泌的影响。研究对象分为两组：磁疗组（16名男性）和磁刺激组（10名男性）。对慢性下背痛患者的腰部区域采用磁场感应形式的磁疗（2.9微特斯拉；频率——40赫兹；方波；双极；Magnetronic MF - 10设备），持续20分钟。对患有相同健康问题的患者，每天进行12分钟的磁刺激（Viofor JPS系统；M2P2程序；感应——25 - 80微特斯拉；频率——200赫兹，波形为复杂的锯齿状，在波高的一半处有一个平台期；双极）。在两组中，这些程序均重复15次（大约上午10:00），周末休息。在6:00、12:00、16:00和24:00采集血清样本，并通过化学发光微量法（波兰DPC；产品编号LKC01）进行检测。在应用前、应用后一天和一个月测定皮质醇的昼夜节律。使用配对和非配对学生检验对数据进行统计学分析。磁疗通过在15次应用后的一天16:00降低皮质醇水平，从而影响其昼夜节律中的分泌，而磁刺激则通过在15次应用后的一个月12:00提高皮质醇水平，这可能表明其对下丘脑 - 垂体轴有长期影响。结果比较表明，磁疗和磁刺激后的一天，皮质醇分泌的昼夜曲线差异显著，约为100%。所有激素波动均未超过皮质醇昼夜水平的生理标准，未达到强烈应激时的高水平。这表明它们对皮质醇水平的控制作用而非显著的应激源性质。
