Problems with balance and binocular visual dysfunction are associated with post-stroke fatigue.

Area of Science:

• Neurology
• Rehabilitation Medicine
• Psychology

Background:

• Post-stroke fatigue is poorly defined and its relationship with other complications requires further investigation.
• Understanding fatigue is critical for stroke rehabilitation and improving patients' daily lives.

Purpose of the Study:

• To investigate the relationship between post-stroke fatigue and balance, gait, and Binocular Visual Dysfunction (BVD).

Main Methods:

• Adult stroke survivors (n=29) were assessed using the Modified Fatigue Impact Scale (MFIS), BVD measures, balance tests, and gait assessments.
• Principle component analysis was used to identify factors of fatigue, with associations analyzed using ANOVA and correlation.

Main Results:

• Three fatigue components were identified: Cognitive, Physical, and Arousal, explaining 71% of the variance in MFIS scores.
• Significant associations were found between Cognitive/Physical Fatigue and BVD, Arousal and balance/dizziness, and Cognitive Fatigue and gait.
• Women reported higher fatigue scores than men.

Conclusions:

• The three identified fatigue components (Cognitive, Physical, Arousal) are clinically relevant for understanding post-stroke fatigue.
• The arousal component of fatigue offers unique insights, distinct from cognitive and physical aspects, important for future research and treatment strategies.
