Electroneuromyography (ENMG)

The electrophysiological examination of central and peripheral nervous system, neuromuscular transmission and the muscles with electroneuromyography (ENMG) is important in the assessment of neuromuscular disorders. The ENMG laboratory is integrated into the Center for Neuromuscular Disorders.

Depending on the clinical problem, different ENMG examinations may be applied:

  • Electroneurography (ENG)
    Determination of nerve conduction with electrical stimulation.
  • Electromyography (EMG)
    Analysis of electrical muscle activity with needle examination.
  • Examination of  neuromuscular transmission
    Analysis of signal transmission form the nerve to the muscle with repetitive nerve stimulation and stimulated single fiber EMG (ssFEMG)
  • Examination of autonomic functions
    Analysis of the vegetative nervous system with determination of the sudomotor sympathetic skin response (SSR) and determination of R-R-interval variation.
  • Motor-evoked potentials (MEP)
    Determination of central motor conduction time with magnetic impulses  for examination of the pyramidal tract function.
In collaboration with the Parki​nson's disease and stroke teams we offer a Botulinum toxin consultation for the treatment of patients with focal dystonia and spasticity.
  • Focal dystonia
    e.g. dystonic Torticollis, writer's cramp
  • Facial movement disorders
    e.g. blepharospasm, hemifacial spasm
  • Focal spasticity
    e.g. after stroke, cerebral palsy, trauma

Referral

A referral to the ENMG or Botulinum toxin consultation can be made by letter, fax (+41 44 255 43 80) or secure mail (nos-dispo-amb@usz.ch).

Scientific Focus

The scientific focus of the research group is the examination of the role of physical exercise on muscle properties and course of neuromuscular and neurodegenerative disorders. One current project funded by the Swiss National Foundation (SNF) examines the effect of regular physical exercise in patients with Huntington-disease. Other clinical-scientific projects are dedicated to the clinical, pathological and genetic characterization of Swiss patients with muscle dystrophies and the McLeod neuroacanthocytosis syndrome.

There are periodic clinical-pathological conferences, twice per year together as a joint meeting with other Swiss neuromuscular specialists. Annual neuromuscular symposium are also organised.
