My doctor is out of town but I did stop by and pick up my repetitive conduction study results because I was curious and my appointment isn't until the 18th. Under conclusions it says "Normal repetitive nerve conduction study with no electrophysiological evidence of defect at the neuromuscular junction. Clinical correlation is recommended," but under findings it says, "The study did show significant decrement response." So, what is decrement response and is it good (normal) that it's significant?
