OBJECTIVE
We have developed a compact device using a spinning permanent magnet (SPM) that induces an electrical field by changing the magnetic flux. We hypothesized that SPM stimulation also reduced spasticity, comparable with repetitive peripheral magnetic stimulation (rPMS) and transcutaneous electrical nerve stimulation (TENS). This study evaluated the effect of a single session of SPM stimulation and compared it with those of rPMS and TENS in healthy individuals.
METHODS
Eleven healthy adult men participated in this study. The active electrode was placed on the soleus muscle, and the reference electrode was placed at 5 cm distal from the active electrode on the medial side of the Achilles tendon. The stimulating electrodes were fixed on the popliteal fossa to stimulate the tibial nerve. The maximum H-reflex (H) and the maximum motor response (M) were measured, and H/M was calculated under the following conditions: a) 15 min SPM stimulation, b) 30 min SPM stimulation, c) 10,000 pulses rPMS, d) 15 min TENS, and e) 15 min rest (control). The devices for SPM, rPMS, and TENS were applied to the belly of the soleus muscle in the prone position.
RESULTS
Compared with the control, H/M significantly decreased under SPM stimulation for 15 and 30 min, as well as under rPMS and TENS ( < 0.005). The changes in H/M under 15 min SPM stimulation were significantly smaller than those under 30 min SPM stimulation and rPMS ( < 0.005).
CONCLUSION
SPM stimulation reduced H/M in healthy individuals and is a potential new treatment for spasticity.

目的
我们开发了一种使用旋转永磁体（SPM）的紧凑型设备，该设备通过改变磁通量来感应电场。我们假设SPM刺激也能减轻痉挛，效果与重复外周磁刺激（rPMS）和经皮电神经刺激（TENS）相当。本研究评估了单次SPM刺激的效果，并将其与rPMS和TENS在健康个体中的效果进行比较。
方法
11名健康成年男性参与了本研究。将有源电极置于比目鱼肌上，参考电极置于跟腱内侧距有源电极5 cm远的位置。刺激电极固定在腘窝处以刺激胫神经。测量最大H反射（H）和最大运动反应（M），并在以下条件下计算H/M：a）15分钟SPM刺激，b）30分钟SPM刺激，c）10000次脉冲rPMS，d）15分钟TENS，以及e）15分钟休息（对照）。将SPM、rPMS和TENS设备应用于俯卧位的比目鱼肌腹部。
结果
与对照组相比，在15分钟和30分钟的SPM刺激以及rPMS和TENS刺激下，H/M均显著降低（<0.005）。15分钟SPM刺激下H/M的变化显著小于30分钟SPM刺激和rPMS刺激下的变化（<0.005）。
结论
SPM刺激可降低健康个体的H/M，是一种潜在的痉挛新疗法。
