- Nerve conduction studies are used to evaluate the function of the nerves.
- There are mainly two types of nerves - motor and sensory. The nerve conduction
studies are specially designed to perform motor nerve conduction and sensory nerve
conduction.
Nerve conduction studies is recommend for following
diseases: - Neuropathy in patients with diabetes
mellitus.
- Connective tissue diseases
- Injury to the nerves
- Carpal
tunnel syndrome
- Cervical/lumbar disc prolapse
- Intake of drugs,
which may affect the nerves. (drugs taken for treatment of tuberculosis/ cancer)
- Guillain Barre Syndrome

placed on the skin over nerves
- and muscles and mild electrical stimulation
is given and the response is recorded.
- Usually two nerves in upper limbs
and two nerves in lower
- Limbs are tested. It may be necessary to test
more nerves depending on the neurological disease.
Instructions
