Smartphone typing behavior: a useful digital biomarker in MS?

Real-world smartphone keyboard interactions can effectively discriminate between multiple sclerosis (MS) patients and controls, and between MS patients with different levels of disability, new findings suggest.

The researchers from Amsterdam University Medical Centers, the Netherlands, studied data on keystroke dynamics in people using a keyboard app called Neurokeys. The information collected included typing speed features (alphanumeric keys) and processing speed features (backspaces and punctuation marks), based on the hold time, release time, or a combination.
