• Median Motor/Sensory Wrist: The stimulator is positioned 3 cm proximal to the wrist crease. The motor active electrode is placed midway between the distal wrist crease and the first metacarpophalangeal joint, directly over the abductor pollicis brevis. Sensory measurements are taken from the wrist to the digit-3 proximal interphalangeal joint. A digital thermometer is used for skin surface temperature measurement.
• Ulnar Motor/Sensory Wrist: The stimulator is also 3 cm proximal to the wrist crease. The motor active electrode is 6.5 cm distal to the cathode stimulating electrode, overlying the abductor digiti minimi muscle in the hypothenar eminence. Sensory measurements are from the wrist to the digit-5 proximal interphalangeal joint, with a digital thermometer for temperature.
• Ulnar Elbow Stimulator: Proximal stimulators are placed below and above the elbow, 10.5 cm apart, with a digital thermometer for temperature measurement.
• Superficial Peroneal: The stimulator is 16 cm proximal to the lateral malleolus, with a response recorded 12 cm from the stimulator. A digital thermometer is used for temperature.
• Peroneal: The stimulator is at the level of the maleoli, with the motor recording electrode set over the midpoint of the extensor digitorum brevis muscle on the foot's dorsum. Temperature is measured with a digital thermometer.
• Sural: The stimulator is 10 cm proximal to the lateral malleolus, with responses recorded at either a 10 cm or 14 cm distance, depending on electrode pair location. Temperature is measured with a digital thermometer.
• Tibial: The stimulator is at the level of the maleoli, with motor recording by volume conduction from the abductor hallucis. A digital thermometer measures temperature.

The document includes a table of measured distances (in cm) and corresponding DSL (msec) values, indicating the conduction velocity measurements. The table provides a range of values for different measured distances, which are critical for assessing nerve function and diagnosing potential neuropathies.

• Ensure accurate placement of electrodes and stimulators as specified for reliable measurements.
• Use the digital thermometer to maintain consistent skin surface temperature, which can affect conduction velocity readings.
• Follow the distance measurement guidelines precisely to ensure accurate conduction velocity calculations.
