...analyzed by a tech, trained to recognize patterns that were indicative of either myopathic or neuropathic dysmotility. (Apparently, each has a distinctive pattern.) So no definitive biopsy that showed myopathy or neuropathy. Wouldn't that be the definitive test? To what level of certainty can they correlate manometric patterns with myopathy or neuropathy? How did they treat your son's dysautonomia and his motility problems? Sorry for the questions, but it helps me understand.
