EDX 2 - Neuropathy and Radiculopathy of the the Upper Extremity. This module entails a comprehensive study of the neuromuscular anatomy of the upper limb. Emphasis on common anatomical variants and how they effect electrodiagnostic interpretation is provided. The major mononeuropathies of the upper limb are fully discussed as well as their electrodiagnostic evaluation. The late responses (F wave, H reflex) are introduced in module one as well. An introduction to techniques of nerve conduction studies in the upper limb is performed in preparation for Lab class 1 (module 6).
