Monitoring how patients with multiple sclerosis or other degenerative diseases use their smartphones could provide valuable information to help get them better treatment.
In an article published in Chaos, researchers used a mobile app to record the keystroke dynamics of a control group and those of subjects in various stages of multiple sclerosis treatment over the course of a year.
Keystroke dynamics show how quickly or slowly someone is typing on a touch screen, the amount of time between letters typed, the number of mistakes made and corrected while typing, and other behaviors. As part of the study, researchers at Amsterdam University Medical Center used a mobile app that tracks how a user is typing on their phone’s keyboard.
In doing so, they observed changes over time in the way people with MS typed that were not seen in subjects who did not have the disease.
James Twose, one of the authors, called the study’s findings a “first promising step” toward using keystrokes to help diagnose changes in patients with chronic diseases like MS.
“The dream is prediction,” said Twose. “If there is some semblance of predictability, the joy would be to forecast the disease in a similar way you do with weather.”
Multiple sclerosis patients generally make clinical visits every 3-12 months, according to the authors, and MRIs are the best way to measure changes in damage to the brain from the disease.
