Walking Troubles of Organic Hemiplegy

Walking Troubles of Organic Hemiplegy (1898) is the first documentary film in the world, created by Romanian neurologist Gheorghe Marinescu. The film depicts several patients walking in four directions against a black background before and after the treatment.

Marinescu came to the idea of making the film after having used the chronophotography under the influence of Étienne-Jules Marey. Marinescu praised the use of the cinematographic techniques in the scientifical investigation.
