Techniques for diagnosis of peripheral nerve loss.
The diagnosis of a peripheral nerve loss is an exacting clinical procedure. This requires a basic knowledge of anatomy, including the variations and anomalies. This also includes various specific tests, such as testing for vibratory sensibility with tuning forks, the presence or absence of sweating, the evaluation of sensibility with two-point discrimination, and the von Frey pressure test. Motor function should be evaluated as to both quantity and quality of impairment. The indications for blocking adjacent nerves with local anesthetic agent are defined and cannot be overemphasized. Electrodiagnostic studies and vascular testing are important for a complete clinical evaluation. The significance of the interrelationship between the nervous system and the vascular system and their relationship in assessing end results should be considered on an individual basis in every case.
