Objectives:To demonstrate diagnostic and prognostic usefulness of electrodiagnostic study in evaluating
acute compressive radial neuropathy.
Method:We reviewed the medical records of acute compressive radial neuropathy with electrodiagnostic
study between January 2007 and December 2009, and we recruited 28 patients. We interviewed all the
patients by telephone to find out the final neurologic status.
Results:Female to male ratio was 4:24 and most of them had normal body mass index. The entire patient
had good recovery and we could dichotomize to ‘Almost normal (24 cases)’ and ‘Good (4)’ group. Only
2 patients showed low amplitude of sensory nerve action potential of superficial radial nerve, but conduction
block of radial nerve was demonstrated on 18 cases (64.3%) between elbow and Erb’s point. In clinical
evaluation, initial motor grade of wrist and finger joint (MPJ) was important because recovery time of
patients with MRC grade 2 or less showed significantly longer than that with MRC grade 3 or more (83.8
±57.6 days vs. 37.1±19.7 days, p<0.05). The degree of radial nerve conduction block was related with
recovery time of motor weakness (linear regression; β=-0.43 p<0.05).
Conclusion:Radial motor nerve conduction study including Erb’s point stimulation is useful method to
evaluate acute compressive radial neuropathy. Furthermore, it is also useful to predict the duration of
motor weakness.
