Normal ulnar nerve conduction velocity across the thoracic outlet: comparison of two measuring techniques.
  1. G W London


    Comparison of ulnar nerve conduction across the thoracic outlet in 30 normal individuals using caliper and steel tape measurements is reported. A difference of 11.3 m/s was noted between the two methods (58.9 +/- 4.20 m/s by caliper; 70.2 +/- 5.20 m/s by tape). Comparison of these values with previous studies and the use of the opposite limb as a control are discussed. This procedure is of clinical importance in the diagnosis of nerve compression in the thoracic outlet syndrome.
