RTsMS and Body Weight-support Treadmill Training After Incomplete Spinal Cord Injury

For repetitive trans-spinal magnetic stimulation - rTsMS (high-frequency or sham), volunteers will be positioned comfortably in a lateral decubitus position. High-frequency rTsMS will be applied with an eight-shaped coil over the tenth thoracic vertebra (10 Hz; 100 pulses per train, 20-second interval between trains; 100% resting motor threshold). For sham rTsMS, two coils will be used: (i) a coil connected to the stimulator will be placed behind the patient (away from the spine) to generate the characteristic sound, and (ii) another coil, disconnected from the stimulator, will be placed on the tenth thoracic vertebra. Both real and sham stimulation will last 20 minutes. Gait training with body weight support will be performed on a Biodex Rehabilitation treadmill for 20 minutes. Researchers will assist the patient in foot placement, knee extension, and pelvis/trunk alignment. Body weight support and treadmill speed will be adjusted based on the patient's performance.
