Background: Fatigue is associated with multidimensional factors in heart failure patients. Investigating longitudinal changes in fatigue and its association in patients undergoing cardiac surgery is needed to create interventions for improving fatigue during recovery.
Aims: This study examined the trajectory of fatigue and its associated factors over time in patients undergoing cardiac surgery.
Objective: We investigated the variation in dimensionality (D2) of neuromagnetic activity over the primary sensorimotor cortex (SM1) in healthy adults performing motor tasks of different difficulty.
Methods: Magnetoencephalography (MEG) was used to record neuromagnetic activity during self-paced, brisk unimanual finger extension at a rate of 1 and 2 Hz using the index finger of the dominant and non-dominant hands in 16 healthy subjects. Motor task difficulty was rated by the relative difference in time measurement between 1 and 2 Hz finger movements of both hands.
