Assessing residual motor function in motor complete spinal cord injury (SCI) patients using surface electromyography (sEMG) is clinically important. Due to the prolonged loss of motor control and peripheral sensory input, patients may struggle to effectively activate residual motor function during sEMG assessments. The study proposes using virtual reality (VR) technology to enhance embodiment, motor imagery (MI), and memory, aiming to improve the activation of residual motor function and increase the sensitivity of sEMG assessments.
By Recruiting a sample of 12 patients with AIS A/B and capturing surface electromyographic signals before, druing and after VR training, RESULTS: Most patients showed significant electromyographic improvements in activation frequency and or 5-rank frequency during or after VR training. However, one patient with severe lower limb neuropathic pain did not exhibit volitional electromyographic activation, though their pain diminished during the VR training.
VR can enhance the activation of patients' residual motor function by improving body awareness and MI, thereby increasing the sensitivity of sEMG assessments.
使用表面肌电图（sEMG）评估运动完全性脊髓损伤（SCI）患者的残余运动功能在临床上具有重要意义。由于运动控制和外周感觉输入长期丧失，患者在sEMG评估过程中可能难以有效激活残余运动功能。该研究提出使用虚拟现实（VR）技术来增强身体感知、运动想象（MI）和记忆，旨在改善残余运动功能的激活并提高sEMG评估的敏感性。
招募了12例美国脊髓损伤协会（AIS）分级为A/B级的患者样本，并在VR训练前、训练期间和训练后采集表面肌电信号。
大多数患者在VR训练期间或训练后，其激活频率和/或五阶频率的肌电图有显著改善。然而，一名患有严重下肢神经性疼痛的患者未表现出自主肌电图激活，尽管其疼痛在VR训练期间有所减轻。
VR可以通过提高身体意识和运动想象来增强患者残余运动功能的激活，从而提高sEMG评估的敏感性。
