Telestroke consultations should include standardized evaluation of key stroke features, which can be obtained by application of validated clinical scales (e.g. Glasgow Coma Scale for evaluation of consciousness). Prehospital assessment of stroke severity remains challenging and inspired researchers to develop adapted scales, among which the Unassisted TeleStroke Scale (UTSS). The UTSS has shown to be a rapid, simple, quantitative measure for the evaluation of stroke severity through telemedicine, without need for assistance from a third party at the patient's bedside. Moreover, it has been shown that this scale can be used for ambulance-based telemedicine for emergent patient transportation.
