Median Nerve Sensory NCS Setup

Setup – Median Sensory NCS

Posted on 08 November 2010. Tags: , , , , , , , , ,

Electrode placement (use the ring electrodes)

14-cm distance (black to black)

  • E1 (black):  Proximal phalanx of the index finger — want to keep away from the metacarpophalangeal (MCP) joint skin, as this may pick up motor conduction artifact.
  • E2 (red):  3-4cm distally from E1.
  • Ground:  Dorsum of hand

14-cm distance (black to black)

  • E1 (black):  Proximal interphalangeal joint (PIP) of the little finger — want to keep away from the metacarpophalangeal (MCP) joint skin, as this will likely pick up motor artifact from the abductor digiti minimi (ADM).
  • E2 (red):  3-4cm distally from E1.  Usually almost hanging off the distal phalanx.
