Please be awere that each lab may have its own normal values. These can vary based upon age, temperature, technique and equipment.

Age generally leads to a lower amplitude and a prolonged distal latency. 

Temperature has significant effects on nerve conduction studies. Low temperature can lead to artificially elevated amplitude, prolonged distal latency and a slowed conduction velocity.

Techniques vary from lab to lab. Our values are based on the techniques described in this manual. 

Equipment varies in sensitivity and thus can lead to some variability responses.
