Diagnostic sensitivity of motor nerve conduction studies in ulnar neuropathy at the elbow.
Seventy-six patients with ulnar neuropathy at the elbow were divided into 3 classes (Grades I, II, and III) according to their clinical features and the maximal motor nerve conduction velocity (MCV), and the amplitude ratios at the across-elbow segment were retrospectively analyzed. To determine the criteria for abnormality, a control study was conducted on 150 healthy volunteers ranging in age...
متن کاملUlnar nerve at the elbow – normative nerve conduction study
INTRODUCTION A goal of our work was to perform nerve conduction studies (NCSs) of the ulnar nerve focused on the nerve conduction across the elbow on a sufficiently large cohort of healthy subjects in order to generate reliable reference data. METHODS We examined the ulnar nerve in a position with the elbow flexion of 90o from horizontal. Motor response was recorded from the abductor digiti m...
متن کاملChanges in nerve conduction with ulnar lesions at the elbow.
Ulnar nerve lesions at the elbow can usually be recognized by a characteristic combination of physical signs. In the hand, there is wasting and weakness of ulnar-innervated muscles with or without sensory loss of appropriate distribution; in the forearm there is often weakness of the ulnarinnervated portion of the flexor digitorum profundus and sometimes of the flexor carpi ulnaris. Further con...
متن کاملPearls & Oy-sters: false positives in short-segment nerve conduction studies due to ulnar nerve dislocation.
The possibility that a technical error may occur during nerve conduction studies due to ulnar nerve dislocation when the elbow is flexed has recently been suggested. We investigated normal volunteers using ultrasonography to observe the effects of ulnar nerve dislocation during elbow flexion on short-segment nerve conduction studies. We found significant conduction block in all of the subjects ...

being physician, patient and community acceptance. Barriers to the former include poor physician education, modest absolute benefit of the intervention being promoted, high risk associated with the intervention, a poor perception of its efficacy and, finally, the results not being generalizable. It is this last issue in which Padma et al, in this edition, have nicely demonstrated that the secon...
