Abstract :
[en] Numerous studies have shown that alterations in physiological reactivity (PR)
after traumatic brain injury (TBI) are possibly associated with emotional deficits.
We conducted a systematic review of these studies that evaluated PR in adults with
moderate-to-severe TBI, either at rest or in response to emotional, stressful, or social
stimuli. We focused on the most common measures of physiological response,
including heart rate (HR), heart rate variability (HRV), respiratory sinus arrhythmia
(RSA), electrodermal activity (EDA), salivary cortisol, facial electromyography (EMG),
and blink reflex.
