Non-pharmacological interventions for the treatment of post-stroke fatigue: A systematic review

Abstract

Background: Post-stroke fatigue (PSF) affects 50% of stroke survivors. Current guidance on management of this condition is limited. Aims: This systematic review and meta-analysis aimed to identify and analyze all randomized clinical trials (RCTs) of non-pharmacological interventions for the treatment of PSF. Summary of review: Six electronic databases were searched from inception to January 2023 for English-language RCTs investigating the efficacy of non-pharmacological interventions versus passive controls in patients with PSF. The primary outcome was fatigue severity at the end of the intervention. The Cochrane risk-of-bias (ROB)2 tool was used to assess evidence quality. A total of 7990 records were retrieved, 333 studies were scrutinized, and 13 completed RCTs (484 participants) were included. Interventions included psychological therapies, physical therapies, and brain stimulation. Nine studies provided sufficient data for meta-analysis, of which seven also had follow-up data. Fatigue severity was lower in the intervention groups at the end of the intervention compared with control (participants = 310, standardized mean difference (SMD) = −0.57, 95% confidence intervals (CIs) (−0.87 to −0.28)) and at follow-up (participants = 112, SMD = −0.36, 95% CIs (−0.83 to 0.10)). Certainty in the effect estimate was downgraded to low for a serious ROB and imprecision. Subgroup analysis revealed significant benefits with physical therapy and brain stimulation but not psychological therapies, though sample sizes were low. Conclusion: Non-pharmacological interventions improved fatigue but the quality of evidence was low. Further RCTs are needed for PSF management.
