Early poststroke clinically significant fatigue predicts functional independence: a prospective longitudinal study

Area of Science:

• Neurology
• Rehabilitation Medicine
• Clinical Research

Background:

• Poststroke fatigue is a common and debilitating condition affecting stroke survivors' recovery and quality of life.
• Understanding the relationship between fatigue and functional outcomes is critical for effective patient management.

Purpose of the Study:

• To investigate the association between poststroke fatigue and functional recovery in ischemic and hemorrhagic stroke survivors.
• To analyze the temporal progression of poststroke fatigue in different stroke subtypes.

Main Methods:

• Prospective cohort study of 79 acute stroke patients (ischemic and hemorrhagic).
• Fatigue assessed using Fatigue Severity Scale (FSS) and Numeric Rating Scale (NRS_fatigue).
• Functional status evaluated with NIH Stroke Scale (NIHSS), Barthel Index (BIADL), and Modified Rankin Scale (MRS).

Main Results:

• Early clinically significant fatigue (CSF) predicts poorer functional independence trajectories.
• Fatigue ameliorates with functional recovery in hemorrhagic strokes but remains stable in ischemic strokes.
• Distinct fatigue progression patterns observed between ischemic and hemorrhagic stroke subtypes.

Conclusions:

• Early poststroke fatigue significantly impacts long-term functional outcomes.
• Proactive management of poststroke fatigue is essential during the subacute recovery phase.
• Tailoring fatigue management strategies based on stroke type may improve patient outcomes.
