- Abstract: An 81-year-old woman sustained a fracture of the vertebra, resulting in grace deformation. After surgery for the spinal fixation, she suffered from left femoral neuropathic pain and motor weakness of both lower extremities. Daily repetitive transcranial magnetic stimulation (rTMS) of the lower extremity area in the right motor cortex was applied using a figure-8 coil connected to a magnetic stimulator (MagPro R30；Nagventure)．One thousand pulses per session were delivered (10 trains of 10Hz for 10 seconds with 25-seconds intertrain interval) in one day, and this treatment continued for 2 weeks except Sunday. The intensity of rTMS was set at the resting motor threshold for that day. rTMS together with physical therapy resulted in a remarkable amelioration of the femoral pain and motor weakness of both lower extremities. Pain on a Visual Analogue Scale dropped from 70％ to 22％, and walking speed and walking rate increased. Functional Independence Measure score increased from 58 to 79, and Euro QOL 5 score increased from 0.419 to 0.768. As previously reported in cases of post-stroke pain and motor weakness, rTMS together with physical therapy exerted measurable beneficial effects on intractable pain and motor weakness caused by spinal orthodontic fixation.
