Summary
[edit]DescriptionSensory neurography median nerve example.png |
English: A screenshot from the Keypoint EMG/NCV software, showing the result of a sensory nerve conduction velocity study of the right median nerve from a person about 30 years. The screenshot is intended to demonstrate the actual signal traces, the derived markings concerning latency and amplitude, the entering of distances and the computation of nerve conduction velocities.
Note the following: Stimulation sites were the third digit (Dig 3), the fourth digit (Dig IV) and the palm. The recording site was over the median nerve at the wrist. The distance from the stimulation to the recording site is indicated in the column "DIST" (in millimeters). The latency from the onset of stimulation is indicated in the "LAT" column (in milliseconds). The CV column indicates the computed conduction velocity (in meters per second). The AMP column indicates the amplitude of the wave (in microvolts). Also note that the hand temperature, a critical factor in the interpretation of a study, is indicated in the left lower corner (in degrees Celsius). |
