Fatigue after aneurysmal subarachnoid hemorrhage is highly prevalent in the first-year postonset and related to low physical fitness: A longitudinal study

Objective The aim of the study was to investigate whether low physical fitness and inactive and sedentary lifestyles play a role in the severity of fatigue in patients with aneurysmal subarachnoid hemorrhage (a-SAH). Design This is a prospective 1-yr follow-up study, including a total of 52 patients with a-SAH. Outcome measures included the Fatigue Severity Scale score, peak oxygen uptake (VO2peak), isokinetic knee muscle strength (peak torque), physical activity (% 24-hr period), and sedentary behavior (% waking hours) and were evaluated at 6 and 12 mos after onset. Results Fatigue was highly prevalent in the first year and reported by 48% of the patients at 6 mos and by 52% at 12 mos after a-SAH. Fatigue was associated with the knee extension (P < 0.001) and flexion strength (P < 0.001). A nonsignificant trend for a relationship was found between fatigue and the aerobic capacity (P = 0.079). No relationships were found between fatigue and physical activity or sedentary behavior. Fatigue could not be predicted by disease-related characteristics. Conclusions Half of the patients were fatigued in the first year after a-SAH. Interventions are necessary to reduce fatigue and should consider exercise training as a potential contributor to a multimodal treatment, preventing debilitating conditions after a-SAH.
