在10名腰痛患者和9名匹配的健康对照中，评估了慢性疼痛状态下初级躯体感觉皮质重组的假说。皮内电刺激按标准、非疼痛和疼痛强度分别施加于左侧背部和食指。用37通道BTI生物磁强计记录刺激部位对侧大脑半球的磁场。早期诱发的磁场的力量(
The hypothesis of reorganization of the primary somatosensory cortex in states of chronic pain was assessed in 10 low back pain patients and nine matched healthy controls. Intracutaneous electric stimuli were applied to the left back and index finger at a standard, a non-painful and a painful intensity. Magnetic fields were recorded by a 37-channel BTi biomagnetometer from the hemisphere contralateral to the site of stimulation. The power of the early evoked magnetic field (
