表面肌电与运动诱发电位在脊髓运动完全性 损伤评估中的比较.

Objective To compare the sensitivity of surface electromyography (SEMG) based brain motor control protocol and transcranial magnetic stimulation (TMS) based motor evoked potentials in the evaluation of patients with complete spinal cord motor injury. Methods 31 patients diagnosed complete spinal cord motor injury were admitted to the China Rehabilitation Research Center from March 2021 to April 2023 underwent sEMG based motor control detection and TMS based motor evoked potential detection, respectively. Results 27 of 31 patients (87%) had at least one channel ranked 4 or 5, and a total of 248 muscles were tested in 31 patients (8 muscles per patient, rectus femoris, biceps femoris, anterior tibialis and gastrocnemius on the right and left sides), of which 79 (32%) muscles could be measured with a channel ranked 4 or 5. 40 of 62 limbs(64%) had at least one channel rank 4 or 5, and 21 of 31 patients (68%) had the highest rank 5 channel. However, none of the 31 patients were positive in TMS-based motor evoked potential testing. Conclusion SEMG is significantly more sensitive than motor evoked potentials in the evaluation of patients with complete spinal cord motor injury. [ABSTRACT FROM AUTHOR]
