The National Institute for Health and Clinical Excellence (NICE) has previously recommended Graded Exercise Therapy (GET) and Cognitive Behaviour Therapy (CBT) as treatments for mild and moderate categories of Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) on the basis of somewhat limited evidence in the form of numerically small clinical trials. The PACE Trial represents the highest grade of clinical evidence – a large randomized clinical trial, carefully designed, rigorously conducted and scrupulously analysed and reported. It provides convincing evidence that GET and CBT are safe and effective therapies and should be widely available for patients with CFS/ME as per the NICE guidelines (
www.nice.org.uk). Adaptive Pacing Therapy (APT) has not been shown to be effective as delivered within the PACE Trial, but this may differ from activity strategies promoted by CFS/ME services nationally. This trial shows that approaches aimed at staying within limits imposed by the illness are less effective than those that test such limits.
In addition to these general benefits, research has shown that some people with CFS/ME can feel much better, and increase their activity levels, by gradually increasing the amount of exercise which they do. A large research trial (The PACE Trial, White 2011) has shown that people with CFS/ME who had support from specialist therapists to gradually increase their exercise levels were more likely to report improvements in function and symptoms at the end of the year-long study.
