Age and Sex Related Differences in Finger Tapping via Marker-less Motion Capture Analysis
The lab records video of people tapping their fingers to see how movement changes with age and sex. They measured 72 healthy adults aged 49–80 and found that females showed declines in speed and size of taps while males did not.

Comparison of Finger Tapping Velocity Features Between Healthy Controls, iRBD, and Parkinson's Disease Using Video Analysis
The team recorded people tapping their fingers on video and measured how fast they moved. They found clear speed differences between Parkinson’s patients and healthy people, but not between early‑stage sleep‑disorder participants and the others, suggesting video taps could help spot disease early.
