Software-Based Finger Joint Range of Motion Analysis
A knowledge-translation review of range-of-motion analysis technologies that defines the landscape of software-based systems and proposes directions for clinical integration.
Peer-Reviewed Research
Everything DIGITS™ measures is validated against established clinical gold standards. Explore the body of work led by Dr. Caitlin Symonette and our research collaborators — spanning range of motion, finger dexterity, hand volume, and remote telerehabilitation.

Develops a webcam-based computer-vision method for hand-volume assessment and compares it against conventional volumetric techniques.
Determines the reliability and validity of AR-based ROM measurement in healthy hands, demonstrating excellent test–retest reliability (ICC > 0.75).
A two-part study comparing DIGITS dexterity outcomes to the nine-hole pegboard test using remote finger-tapping exercises.
A scoping review of 28 studies on telerehabilitation technologies, concluding that telerehab can serve as a reliable substitute for in-person goniometer measurements.
Evaluates DIGITS across devices and operating systems, demonstrating differences of 2°–3° for extension and 3°–8° for flexion versus reference measurements.
Beta testing showed 6–9 degrees of difference from in-person measurements, with an ICC of 0.98 for extension.
