Mark Vink

Mark A. Vink, MD, is a General Practitioner and insurance doctor in The Netherlands. He lives with severe ME/CFS triggered by pneumonia and prolonged by Graded Exercise Therapy (GET). As a result of his adverse experience with GET, he has been a vocal critic of the PACE trial. One piece written about the PACE trial garnished him a nomination for the 2016 John Maddox Prize, an international award for an individual who promotes sound science despite difficulty or hostility in doing so.

While bedridden, he carried out a biomedical study on himself, collecting blood with finger prick lancets and pediatric sized tubes. By measuring creatine kinase, inorganic phosphate and lactic acid before and after trivial exercise (i.e., walking the 5 to 6 yards from his bed to the toilet and back), he showed that his aerobic energy production and lactic acid excretion were both impeded.

An open letter to Psychological Medicine about “recovery” and the PACE trial
Dr. Vink was one of the signatories of an open letter to Psychological Medicine about “recovery” and the PACE trial dated March 13, 2017 urging Psychological Medicine to retract a paper claiming recovery for ME/CFS patients by using Graded Exercise Therapy and cognitive behavioral therapy.
