Abstract
Digital still cameras capable of filming short video clips are readily available but the quality of these recordings for telemedicine has not been reported We performed a blinded study using four commonly available digital cameras A simulated patient with a hemiplegic gait pattern was filmed by the same videographer in an identical brightly lit indoor setting Six neurologists viewed the blinded video clips on their PC and comparisons were made between cameras between video clips recorded with and without a tripod and between video clips filmed on high or low quality settings Use of a tripod had a smaller effect than expected while images taken on a high quality setting were strongly preferred to those taken on a low quality setting Although there was some variability in video quality between selected cameras all were of sufficient quality to identify physical signs such as gait and tremor Adequate quality video clips of movement disorders can be produced with low cost cameras and transmitted by email for teleneurology purposes
