| Outline of Final Research Achievements |
We evaluated neurophysiological function of brachial plexonopathy. In treatment resistant cases, size of CMAP on ECR were smaller than others, CMAP ratio (distal/proximal) of ECR decreased, F wave of radial nerve disappeared, and distal latency on median nerve delayed.
As for distal part, we measured vibration detection threshold (VDT), cooling detection threshold (CDT), and heat pain sensation of 5/10 in visual analog scale (HP5) using case4 in familial amyloid polyneuropathy. CDT correlated with both SCV and SNAP, and VDT correlated with SNAP. As hypesthsia and hypargesia happen at the same time in these patients, HP5 seems not correlated to neurophysiological function measured by SCV or size of SNAP.
