Background: Post-stroke fatigue (PSF) affects up to 92% of stroke patients, causing significant personal, societal, and economic burden. Global stroke guidelines recommend education and strategies to manage PSF, yet there are no proven treatments. Group-based cognitive behaviour therapy interventions for fatigue have had positive results in other health conditions (i.e., multiple sclerosis, traumatic brain injury), however, there is no evidence for post-stroke.
Aims: In FASTER (Fatigue After STroke Educational Recovery), we assessed a group-based, educational intervention for PSF compared to general stroke education alone.
Methods: FASTER was a prospective, multi-centre, two-arm, single-blinded, phase III (parallel, superiority) randomized control trial. Participants were randomized to general stroke education/control (EC; n = 100) or a fatigue management group (FMG; n = 100) intervention and assessed at baseline, 6-weeks, and 3-months. The FMG involved 60-minute weekly psychoeducation sessions over six weeks. Participants were adults with stroke in the past 3-24 months and clinically significant fatigue. Co-primary outcomes were Fatigue Severity Scale (FSS) and Multi-dimensional Fatigue Inventory-20 (MFI-20) total scores.
Results: When adjusted for significant confounders, 6-week FSS and MFI-20 group score differences were -0.13 [95% CI, -2.93-2.67], p=0.93, and 0.64 [95% CI, -0.84- 2.12], p=0.40, respectively. Across all participants, every week post-stroke was associated with a significant decrease in FSS (0.4 points, SE 0.2, p=0.02), with greater decreases in the FMG group. Every week post-stroke was associated with marginally significant increases in MFI-20 (0.2 points, SE 0.1, p=0.07), with greater increases in EC group. Both groups had similar secondary outcomes at 6-weeks and 3-months.
Conclusion: We found no evidence of significant group-level benefits of FMG over and above general stroke education, though fatigue outcomes were in the direction of a treatment effect. Educational, group-based interventions for PSF should continue to be refined and examined, including consideration of potential impacts at an individual-level.
