A new system using a Leap Motion device offers a rapid, objective method for quantifying finger tremor severity. This non-contact approach provides a valuable reference for future clinical assessments.

Area of Science:

  • Biomedical Engineering
  • Neurology
  • Medical Devices

Background:

  • Clinical assessment scales are standard for evaluating tremor severity.
  • Existing objective tools (e.g., accelerometers, EMG) are often complex, time-consuming, or capture incomplete data.
  • A need exists for automated, quantitative tremor assessment in clinical settings.

Purpose of the Study:

  • To develop a rapid, objective, and quantitative system for measuring finger tremor severity.
  • To utilize a small, portable optical device (Leap Motion) for tremor assessment.

Main Methods:

  • A non-contact, portable optical device (Leap Motion) was employed to capture finger movements.
  • Three distinct algorithms were developed to quantify tremor severity based on recorded movements.
Keywords:
