This trial has been called the “sister trial” to PACE. Nearly 300 individuals diagnosed with Oxford-defined CFS (which considers only fatigue) took part, including a sizeable number described as “non-ambulatory”. The group was, on average, more severely affected than the group that participated in PACE. Participants were assigned to three groups: a) pragmatic rehabilitation; b) supportive listening; or c) medical treatment as usual. The two therapy programmes consisted of 10 sessions and were delivered at home by general nurses. At the completion of the programmes, self-assessed fatigue – but not physical function - was marginally better for the pragmatic rehabilitation group than for the other two groups. However, at the trial’s primary endpoint which was a year later, there were no longer any significant group differences.
A 2015 paper attempted to explore the psychological factors that predicted improvement at the primary endpoint (which is puzzling, given that the trial did not yield any reliable treatment effects).This also reported that there were no group differences on an objective measure of fitness (based on the step test).
