Author Description

This book was developed to assist physical therapy students and clinicians in learning the techniques, interpretation and use of electroneuromyography evaluation in the differential diagnosis of patients with neuromuscular disorders. It provides the physiological basis and techniques of this diagnostic test through the use of nerve conduction studies and needle electromyography. Readers will learn the application of these techniques to the upper and lower extremities, plus the interpretation of results/reports through case studies. Differential diagnosis of abnormalities that are distributed throughout the neuromuscular system will be presented. Knowledge of basic anatomy related to peripheral nerve and root distributions is being assumed.
