Graded exercise therapy

Graded exercise therapy (GET) is a form of physical therapy for the treatment of chronic fatigue syndrome (CFS) where physical activity is gradually increased over time. It is a treatment offered to ME/CFS patients in the UK by the National Health Service (NHS) as specified in the NICE guidelines. The use of Graded Exercise Therapy as a treatment is based on the disputed deconditioning hypothesis, and the highly controversial biopsychosocial model (BPS) of ME/CFS.

Patient reports of harm
Clinical trials have resulted in mixed results. Surveys of patients conducted by patient charities have universally found Graded Exercise Therapy to be harmful, although a minority of patients found it helped them or simply ineffective. A number of severely ill patients have reported that starting Graded Exercise Therapy will moderate symptoms cause a severe escalation of symptoms, leaving them permanently worse. Two highly influential peer-reviewed articles often used to support the use of Graded Exercise Therapy, the Cochrane review and the PACE trial, have had widescale calls for retraction based on criticism of the scientific method and standards used.

Robin Brown, a British doctor with ME/CFS has created petition that many thousands have signed calling for GET and related CBT to be removed from the UK treatment guidelines immediately.

Physical fitness unchanged
A number of studies by proponents of GET have found that it did not improve fitness, when self-rated perception of fatigue did improve after GET, no improvements in exercise capacity were statistically significant. The controversial PACE trial's 6 minute walk test results showed those successfully completing GET were unable to walk as far as older patients awaiting a lung transplant or those with heart failure; data that was omitted from the original trial report.

Patient analysis of PACE results
Graham McPhee and others created videos investigating the PACE trial data in relation to GET. Several re-analyses of the PACE trial results have been published since the detailed PACE trial data was released into the public domain.

Fear of exercise
The PACE trial investigators have stated that they believe a significant maintaining factor in the persistence of ME/CFS is fear of exercise. This claim has been criticized as unsupported by trial results. A study by Nijs et al. in 2004 concluded:

CDC withdrawal of GET treatment
July 3, 2017, The Centers for Disease Control and Prevention's (CDC) website Chronic Fatigue Syndrome page has been changed to "Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS)" and GET and CBT recommendations have been removed.

StopGET petitions
A number of different patients and patient charities have created #stopGET petitions to campaign for an end to graded exercise therapy treatment in ME/CFS:
 * Stop GET trials - MEAction
 * Stop harming ME/CFS patients - take CBT/GET out of NICE guidelines NOW. - Dr. Hng's UK petition to stop GET and CBT
 * The NICE guideline for CFS/ME is not fit for purpose and needs a complete revision - a petition the ME Association delivered to Andrew Dillon at NICE
 * Suspend all trials of graded exercise therapy in children and adults with ME/CFS - UK parliament petition (archived)
