Computer vision of smartphone video has potential to detect functional tremor

Functional neurological disorders (FND) constitute more than 15% of referrals to neurology clinics [1], and functional tremor is the most common functional movement disorder [2]. Physical features of a functional tremor include: tremor present at rest, posture and action; variability in frequency and direction; and reduction or abolition of tremor with distraction [2]. Tremor judgement by eye is inherently subjective and imprecise [3], and a need for objective tests is recognised [4]. Although laboratory accelerometery can distinguish functional tremor from other tremors [4], it is a limited resource.
