Abstract
Background:Numerous studies have shown the value of patient home video recordings within the field of epilepsy. Despite the growing influence of mobile technology and telemedicine, there is a paucity of studies examining the role of home videos in the diagnosis of movement disorders.Objective:To characterize the clinical value of patient home videos in a movement disorders practice.Methods:We performed a retrospective review from our video database over the past 10 years and identified 20 encounters where an in-person, clinic evaluation and studio video were supplemented by a home video. We reviewed these encounters to determine if the home video added additional value to the clinic video. The home videos were screened by 3 movement disorders attendings and 3 movement disorders fellows to assess for quality and to determine whether or not the patient phenomenology could accurately be identified.Results:Of the 20 videos identified, 10 (50%) were determined to be of additional clinical value. In 62.4% of evaluations movement disorders attendings and fellows were able to identify phenomenology from the home videos consistent with the final diagnosis. Videos rated as “poor” quality had significantly lower odds of leading to a correct phenomenology (odd ratio: 0.07, 95% confidence interval [0.01–0.72]) than those rated as “excellent” quality.Conclusions:Patients should be encouraged to produce good quality home videos, particularly in paroxysmal or fluctuating movement disorders, as they may add value to the eventual diagnosis and management.
Highlights
Video recordings have a well-established utility in the medical field as a teaching, diagnostic, and research tool
Patient home videos, obtained on a smartphone, increased the chance of correctly diagnosing an epileptic event when compared to chance of obtaining a diagnosis from history and physical examination alone (95.2% vs 78.6%) [2]
The database includes videos taken of movement disorders patients in our clinic recording studio by clinical professionals and videos recorded by patients (“selfies”), their friends, family members or care givers in a home, hospital, vehicle, or some other environmental settings that were provided to the Parkinson’s Disease Center and Movement Disorders Center (PDCMDC)
Summary
Video recordings have a well-established utility in the medical field as a teaching, diagnostic, and research tool. In the field of epilepsy, the benefits of home video recordings have been well established. Patient home videos, obtained on a smartphone, increased the chance of correctly diagnosing an epileptic event when compared to chance of obtaining a diagnosis from history and physical examination alone (95.2% vs 78.6%) [2]. Home videos have been shown to be a valuable adjunct tool in identifying paroxysmal events in infants, increasing the accuracy of diagnosis of both epileptic events and non-epileptic events by 3.9% and 11.5%, respectively [4]. Numerous studies have shown the value of patient home video recordings within the field of epilepsy. Despite the growing influence of mobile technology and telemedicine, there is a paucity of studies examining the role of home videos in the diagnosis of movement disorders
