五十肩患者における肩甲上・肩甲背・腋窩・筋皮神経の運動神経伝導潜時の測定

抄録

A Few authors have reported these latency studies till now. The measurement of these latencies will help our neurological approach to palsy of brachial plexus injury, entrapment neuropathy of upper extremity etc.
We studied motor nerve latencies of suprascapular, clorsal scapular, axillary and musculocutaneus nerves in 33 patients with stiff and painful shoulder. These latencies were measured between Erb's point (stimulation electrode) and the mid point of the muscle belly innervated by these nerves (needle electrode).
The average times of latencies were as follows; suprascapularn.: 2.85 msec in M. Supraspinatus and 3.56 msec in M. Infraspinatus, dorsal secapular n.: 3.53 msec in M Rhomboid, axillar n.: 3.89 msec in M. Deltoid, musculocutaneus n.: 4.46 msec in M. Biceps.
