Electro-Diagnosis and Electrotherapy in Peripheral Nerve Lesions

Sensory nerve action potentials in patients with peripheral nerve lesions.

In 1949 Dawson and Scott described a method of examining sensory impulses in human peripheral nerves. By their technique, the median or ulnar nerve at the level of the wrist was stimulated electrically using single shocks, and the action potential of the afferent volley recorded through surface electrodes placed over the nerve trunk at a higher level in the arm. The afferent volley contained bo...

Musculoskeletal ultrasound for peripheral nerve lesions.

Although the combination of a detailed physical examination and a subsequent electrodiagnostic study is used for the diagnosis of peripheral nerve disorders, prompt imaging may also be necessary in daily practice. In this regard, as having higher spatial resolution, and being a faster, more cost-effective and dynamic study; ultrasound (US) has become a very convenient first-line imaging modalit...

Peripheral compression lesions of the ulnar nerve.

ANATOMY The anatomical course of the ulnar nerve renders it particularly vulnerable at the elbow and at the wrist. At both sites the nerve or its terminal branches pass through narrow canals in which small space-occupying lesions may exert pressure. As the nerve crosses the elbow it passes from the extensor aspect of the arm into the flexor mass of the forearm, running between the two heads of ...

Peripheral Nerve Injuries: Principles of Diagnosis

Nanotechnology for peripheral nerve regeneration

Peripheral nerve injuries (PNI) can lead to lifetime loss of function and disfigurement. Different methods such as conventional allograft procedures and using of biological tubes have problems for damaged peripheral nerves reconstruction. Designed scaffolds with natural and synthetic materials are now widely used in the reconstruction of damaged tissues. Utilization of absorbable and non-absorb...
