Thank you for your response. Actually I am a resident in training and I did get it on a patient while testing for the ulnar f wave. My attending who has been doing emgs for 25+ years retested it and got the same H reflex response. He than told me in all these years that was the first time he had seen one. I was considering getting it published and I am just trying to gather as much information as I can.
By the way do you know why children have H reflexes but adults tend to lose them?
