Objective. Transcutaneous cervical spinal cord stimulation (tsCSC) has been demonstrated to activate the dorsal root and activate targeted muscles. However, it is unclear whether tsCSC can elicit functionally relevant movements of the upper limb for assistive/rehabilitative purposes. Approach. The current study sought to elicit arm and hand movements by tsCSC by placing an electrode array near the cervical segments of the spinal cord. Anode stimulation current pulses were delivered to the dorsal side at 120 Hz and 30 Hz in separate trials. The elicited joint kinematics were captured using a motion tracking system. Main results. The results revealed that distal and proximal joint movements can be elicited either independently or synergistically. Specifically, different motions, including flexion and extension of the elbow, wrist, and five digits, can be selectively elicited by adjusting the stimulation parameters, such as stimulation location and stimulation...

通过经皮颈椎脊髓刺激诱发上肢运动。

目的。经皮颈椎脊髓刺激（tsCSC）已被证明可以激活背根并激活目标肌肉。但是，尚不清楚tsCSC是否可以出于辅助/康复目的引发上肢的功能相关运动。方法。当前的研究试图通过将电极阵列放置在脊髓颈段附近来通过tsCSC引起手臂和手部运动。在单独的试验中，将阳极刺激电流脉冲以120 Hz和30 Hz的速率输送到背侧。使用运动跟踪系统捕获所引起的关节运动学。主要结果。结果表明，远端和近端关节运动可独立或协同引发。具体来说，包括肘部，腕部和五位数的弯曲和伸展在内的不同动作，
