I was extremely impressed with Dr Rowe. Sometimes researchers focused on OI can see ME and PEM in overly simplistic terms, but he does seem to have the full picture. And his research is geared at delving into it even further: not just typical PEM, but also cognitively, socially, and biomechanically triggered PEM.
He's looking for answers based on sound biomedical theories, and seems to be using sound methodology.
