Participants will complete two experimental conditions: a mentally fatiguing Stroop task and a control condition involving passive documentary watching, separated by at least 48 hours. Postural control will be assessed using force plate measures of center of pressure displacement during bipedal and unipedal stance, with and without concurrent cognitive dual-tasking. In parallel, spinal reflex excitability will be evaluated using H-reflex recordings from the triceps surae muscles across sitting and standing postures.\n\nThe primary aim is to determine whether mental fatigue increases postural sway, particularly in more challenging balance conditions such as single-leg stance. The secondary aim is to examine whether mental fatigue alters the normal modulation of spinal reflex excitability across progressively demanding postural tasks. Additional biomechanical and neuromuscular measures, including EMG activity and hip kinematics, will be recorded to provide insight into underlying control mechanisms.\n\nThe study will include approximately 26 participants, with each serving as their own control. Data will contribute to understanding how cognitive fatigue influences balance control and spinal-level neuromuscular regulation.",[82],"Mental Fatigue",[84,85,86,87,88,89],"Postural control","Center of pressure","Spinal reflex excitability","H-reflex","Stroop task","Electromyography","NOT_YET_RECRUITING","2026-06-15",{"date":93,"type":94},"2026-06-16","ACTUAL",{"date":96,"type":76},"2026-07-01",{"date":98,"type":76},"2026-12-01",{"name":5,"class":6},1]
