Neuromuscular disorders affect the nerves that control voluntary muscles, like the ones in your arms and legs. When these nerve cells become unhealthy or die, communication between the nervous system and muscles breaks down. 

Valley’s neurophysiology team is highly trained in diagnosing and treating all types of neuromuscular disorders, including: 

  • Amyotrophic lateral sclerosis (ALS) (Lou Gehrig’s disease)
  • Guillain-Barre syndrome and chronic inflammatory demyelinating polyneuropathy
  • Multiple sclerosis
  • Muscular dystrophy
  • Myasthenia gravis
  • Myopathy
  • Polyneuropathy with variants
  • Spinal muscular atrophy

Diagnostic Services for Neuromuscular Disorders

Neurologists use a range of diagnostic tools to diagnose neuromuscular disorders. In addition to a clinical evaluation and a family history, testing may include:

Electromyography (EMG)

EMG is a diagnostic procedure to assess the health of muscles and the nerve cells that control them. These nerve cells transmit electrical signals that cause muscles to contract. During a needle EMG, a needle electrode inserted directly into a muscle records the electrical activity in that muscle. EMG results can reveal nerve disorders, muscle dysfunction or problems with nerve-to-muscle signal transmission.

Serum Enzyme Tests

Serum enzyme tests can measure key enzyme levels associated with various neuromuscular diseases as well as increased muscle protein levels that build up as muscles are destroyed, making them an important aid in the diagnosis of neuromuscular diseases.

Muscle Biopsy

For some neuromuscular diseases, a final diagnosis depends on the analysis of a muscle biopsy. By removing a small amount of muscle tissue, the physician can test it for cellular protein abnormalities or characteristic changes in muscle composition. This is a minimally invasive surgical procedure, done under local anesthesia.

Treatment Options for Neuromuscular Disorders

The goal of treatment is to reduce symptoms, increase mobility and lengthen life. Depending on the specific diagnosis, various neuromuscular disorder treatments are available to target the underlying pathology, reverse symptoms and improve the patient’s quality of life.
