研究设计：病例对照研究。目的：研究正常人胫前肌运动单位数及其在脊髓损伤后的变化。地点：中国北京中国康复研究中心。方法：采用改良多点刺激法(AMPS)对45名对照受试者(青年组35人，平均年龄36岁；老年组10人，平均年龄65岁)进行运动单位数估计。对20例脊髓损伤患者(亚急性组10例，平均年龄39岁，慢性组10例，平均年龄34岁)进行3次3个月的检查。结果：对照组和亚急性脊髓损伤组TA肌的平均MUNE分别为188+/-20和40+/-33(P
Study design: Case-control study.Objective: To investigate the number of motor units from the tibialis anterior (TA) muscle in normal subject and its change after SCI.Setting: China Rehabilitation Research Center, Beijing, China.Methods: Motor unit number estimation (MUNE) in 45 control subjects (35 young subjects with an average age of 36 years, and 10 elderly subjects with an average age of 65 years) was performed by using adapted multiple point stimulation method (AMPS). Twenty patients with SCI (10 subacute patients with an average age of 39 years, and 10 chronic patients with an average age of 34 years) were also examined for three times in 3 months with the same method.Results: The mean MUNE value of the TA muscle was 188 +/- 20 in the control group, and 40 +/- 33 in subacute SCI patients (P
