Health-related quality of life in patients with chronic fatigue syndrome: group cognitive behavioural therapy and graded exercise versus usual treatment. A randomised controlled trial with 1 year of follow-up
Chronic fatigue syndrome ( CFS ) produces physical and neurocognitive disability that significantly affects health-related quality of life ( HRQL ) .  Multidisciplinary treatment combining grade d exercise therapy ( GET ) cognitive behavioural therapy ( CBT ) and pharmacological treatment has shown only short-term improvements . To compare the effects on HRQL of ( 1 ) multidisciplinary treatment combining CBT , GET , and pharmacological treatment , and ( 2 ) usual treatment ( exercise counselling and pharmacological treatment ) at 12 months of follow-up . Prospect i ve , r and omized controlled trial with a follow-up of 12 months after the end of treatment . Patients consecutively diagnosed with CFS ( Fukuda criteria ) were r and omly assigned to intervention ( n = 60 ) or usual treatment ( n = 60 ) groups . HRQL was assessed at baseline and 12 months by the Medical Outcomes Study Short-Form question naire ( SF-36 ) . Secondary outcomes included functional capacity for activities of daily living measured by the Stanford Health Assessment Question naire ( HAQ ) and comorbidities . At baseline , the two groups were similar , except for lower SF-36 emotional role scores in the intervention group . At 12 months , the intervention did not improve HRQL scores , with worse SF-36 physical function and bodily pain scores in the intervention group . Multidisciplinary treatment was not superior to usual treatment at 12 months in terms of HRQL . The possible benefits of GET as part of multidisciplinary treatment for CFS should be assessed on an individual patient basis
