Summary

High voltage electrical stimulation provides normative brachial plexus values. These electrodiagnostic measures aid in diagnosing thoracic outlet syndrome by identifying prolonged nerve signal latencies.

Area of Science:

  • Neurophysiology
  • Clinical Electrophysiology
  • Nerve Conduction Studies

Background:

  • Establishing normative electrodiagnostic values is crucial for accurate clinical interpretation.
  • High voltage electrical stimulation offers a method to assess nerve conduction across specific brachial plexus segments.

Observation:

  • Twenty-two patients without ulnar nerve complaints contributed to the normative data pool.
  • High voltage stimulation was applied at Erb's point, C8, and T1 roots, with recordings from the abductor digit minimi muscle.

Findings:

  • Normative upper limits for absolute latencies were established: 13.9 ms (Erb's point), 14.5 ms (C8), and 14.5 ms (T1).
  • Normative lower limits for amplitude were determined: 4.8 mV (Erb's point), 3.4 mV (C8), and 2.9 mV (T1).

  • Upper limits for interpeak latencies were 1.4 ms (C8 to Erb's point) and 1.2 ms (T1 to Erb's point).

    • Implications:

    • The study demonstrates the utility of these normative values in diagnosing thoracic outlet syndrome.
    • Abnormal latencies on the symptomatic side of a thoracic outlet syndrome case confirmed the diagnostic value of the method.
