Sixty-one individuals admitted for rehabilitation with a diagnosis of complete tetraplegia due to traumatic spinal cord injury underwent prospective examinations for motor and sensory recovery. The amount of motor, light touch and sharp/dull (pin prick) sensory recovery was independent of the initial neurologic level of injury between C4 and C8. In the interval between one month and one year following injury, the American Spinal Injury Association Motor Score increased an average of 8.6 +/- 4.7. However, the rate of motor recovery rapidly declined in the first six months and then approached plateau. Ninety-seven percent of muscles with Grade 1/5 ("Trace") or 2/5 ("Poor") strength one month after injury recovered to > or = 3/5 ("Fair") strength by the time of first annual follow-up. Muscles with 0/5 strength one month after injury and located one neurological level below the most caudal level having motor function regained > or = 3/5 strength in only 27 percent of cases at one year follow-up and at two levels below in only 1% of cases.
61名因创伤性脊髓损伤而被诊断为完全性四肢瘫痪并入院接受康复治疗的患者接受了运动和感觉恢复的前瞻性检查。运动、轻触觉以及锐/钝（针刺）感觉恢复的程度与C4至C8之间最初的神经损伤水平无关。在受伤后1个月至1年的间隔期内，美国脊髓损伤协会运动评分平均增加了8.6±4.7。然而，运动恢复率在最初6个月迅速下降，然后趋于平稳。受伤后1个月时肌力为1/5（“痕迹”）或2/5（“差”）的肌肉，到首次年度随访时，97%恢复到≥3/5（“尚可”）的肌力。受伤后1个月时肌力为0/5且位于具有运动功能的最尾端水平以下一个神经节段的肌肉，在1年随访时仅有27%的病例恢复到≥3/5的肌力，而在两个神经节段以下的仅有1%的病例。
