Neurological examination is possible using telemedicine

Abstract

To compare the reliability of neurological examination performed by telemedicine and face to face, a junior doctor examined 23 patients face to face, these examinations being witnessed either by one or by two telemedicine observers using a telemedicine video-link at 384 kbit/s. The gold standard was a face-to-face examination from a panel of six consultant neurologists. Power, deep tendon reflexes, plantar responses, coordination, sensation, eye movements, facial strength, tongue movements, sitting balance and gait were studied. Seventeen patients satisfied the inclusion criteria, and a total of 1084 matched pairs of observations were made. The reliability of the telemedicine examination ranged from fair to moderate for deep tendon reflexes, coordination and eye movement, to near perfect for plantar responses. Overall, examination by telemedicine compared favourably with face-to-face examination. Telemedicine examination was more sensitive in detecting abnormalities than face-to-face examination for all the neurological tests studied and more specific for all but one (plantar responses). The study showed that neurological examination using telemedicine is at least as good as face-to-face examination performed by a junior doctor.
