EMG Lab Services

Nerve Conduction Studies

Nerve Conduction Studies:
Left panel - normal
Center panel - ulnar neuropathy at the wrist
Right panel - severe ulnar neuropathy at the elbow

The EMG Lab provides comprehensive and detailed testing many of which are not available elsewhere. Adult and pediatric patients are welcome at both locations. Services offered include:

  • Neuromuscular Consultation - A directed neuromuscular examination is always performed, and a clinical and electrodiagnosis is provided. If the referring physician requests further therapeutic advice, the neuromuscular consultation is an option.
  • Motor nerve conduction studies - provides quantitative information about motor nerve fibers in patients with focal or generalized muscle weakness
  • Sensory nerve conduction studies - provides quantitative information about sensory nerve fibers in patients with focal or generalized sensory symptoms
  • Late responses: F and H responses - provides quantitative information concerning proximal nerve segments not easily assessed with motor and sensory nerve studies
  • Repetitive nerve stimulation studies - useful in diagnosis of muscle weakness due to disorders of the neuromuscular junction (eg. myasthenia gravis, Lambert Eaton myasthenic syndrome)
  • Routine qualitative needle electromyography - useful in assessing the state of the motor unit, and in distinguishing muscle weakness from peripheral nerve, nerve root or anterior horn cell diseases from those caused by muscle diseases
  • Single Fiber electromyography - helpful in documenting neuromuscular junction disorders (eg. myasthenia gravis) when repetitive nerve stimulation is normal
  • Skin biopsy - for evaluation of cutaneous sensory unmyelinated pain fibers in patients with small fiber sensory neuropathy not detectable on routine nerve conduction studies
  • Digital and video photography - documents neurologic findings
