Functional assessment of peripheral nerve injury and repair

Based on 191 follow-ups of patients with peripheral nerve injury and repair, the authors suggest that a reasonable assessment should consist of motor, sensory, and autonomic nerve indices. It is also suggested that a method of functional assessment about the autonomic nerve should be included. The method of evaluating motor function should be selected according to the site of the nerve injury. Lovett's method was adopted for nerve injury at the wrist and lower third of the forearm, as well as the British Medical Research Council (BMRC) method for nerve injury at the upper forearm or other nerves. Standards and grades of the BMRC should be raised somewhat, in order to compare more consistently with the results obtained using the method of Lovett; then both can be correlated satisfactorily.
