Electrodermal response and outcome from severe brain injury

The relation of electrodermal response measures to outcome from early post-traumatic vegetative state (VS) was investigated in 15 brain-injured and five control subjects. Brain-injured subjects were in acute VS or persistent VS (PVS), or had recovered from acute VS (RVS). Significant group differences were found on all electrodermal response measures, primarily due to the greater amplitude, number and consistency of responses in control …
