Biceps vs extensor carpi radialis recovery in Frankel grades A and B in spinal cord injury patients

Abstract

Clinical literature suggests that the wrist extensors show a trend of achieving functional strength earlier than the biceps after spinal cord injury (SCI). Basic research, however, demonstrated that proximal muscles recover earlier than distal muscles after partial denervation. The purpose of this study was to compare biceps to extensor carpi radialis (ECR) recovery of muscle strength in 39 motor complete cervical SCI patients. Bice ,e s (n = 19) and ECR (n = 20) with a 72 hour or 1 week motor grade of 1/5 were compared. Testing was performed weekly for 1 month, and again at 2, 3, 6 and 12 months post injury. The median recovery times to increase one motor grade were: biceps = 2 months and ECR = 2.5 months (p < 0.3). The median recovery times to increase two motor grades were: biceps = 2 months and ECR = 3 months (p < 0.4). In conclusion, there was no significant difference between the rates of recovery of the biceps and the ECR up to 12 months post SCI.

Rapid recovery of segmental neurological function in a tetraplegic patient following transplantation of fetal olfactory bulb-derived cells

“…This recovery is usually complete within the first year post-injury. [21][22][23][24][25] A relationship between preserved pinprick sensation and recovery of wrist extensor function has been reported in subacute quadriplegia. 26,27 Culture immunostaining An important issue concerns the identity of the cells being transplanted in the Beijing study.…”

Cruciate paralysis, hypothesis for injury and recovery

“…Metal fragments seen at the midline are actually lateral to the cord space grades. 4 The patients facial injuries did not allow accurate communication and thus, ASIA sensory examination was not recorded. Initially, her motor score was 0/50 with only mild lower extremity de®cits.…”
