Systems and methods for tremor detection and quantification

A system for detecting tremors in a subject, the system comprising:

• a data storage device storing instructions for detecting tremors in a subject;
• and
• a processor configured to execute the instructions to perform a method including:
• receiving data from a digital device, the data comprising a plurality of digital device positions and a plurality of timestamps, each timestamp in the plurality of timestamps being associated with a digital device position in the plurality of digital device positions;
• determining a plurality of frequencies of hand movements of the subject based on the plurality of digital device positions and the plurality of timestamps;
• determining a subportion of the data corresponding to one or more frequencies of hand movements above a low tremor threshold;
• and
• determining a magnitude of tremors of the hand of the subject based, at least in part, on the subportion of the data.

A non-transitory computer readable medium for use on a computer system containing computer-executable programming instructions for performing a method for detecting tremors in a subject, the method comprising:

• receiving data from a digital device, the data comprising a plurality of digital device positions and a plurality of timestamps, each timestamp in the plurality of timestamps being associated with a digital device position in the plurality of digital device positions;
• determining a plurality of frequencies of hand movements of the subject based on the plurality of digital device positions and the plurality of timestamps;
• determining a subportion of the data corresponding to one or more frequencies of hand movements above a low tremor threshold;
• and
• determining a magnitude of tremors of the hand of the subject based, at least in part, on the subportion of the data.

A computer-implemented method for detecting tremors in a subject, comprising:

• receiving data from a digital device, the data comprising a plurality of digital device positions and a plurality of timestamps, each timestamp in the plurality of timestamps being associated with a digital device position in the plurality of digital device positions;
• determining a magnitude of tremors of the hand of the subject based, at least in part, on the data comprising the plurality of digital device positions and the plurality of timestamps;
• and
• determining a degree of cognitive impairment of the subject based, at least in part, on the data comprising the plurality of digital device positions and the plurality of timestamps.
