Area of Science:

  • Biomechanics
  • Rehabilitation Engineering
  • Human-Computer Interaction

Background:

  • Accurate hand kinematic analysis is crucial for understanding motor control and diagnosing movement disorders.
  • Existing methods for analyzing hand kinematics can be complex and time-consuming.
  • The peg-moving task is a standard assessment for fine motor skills.

Observation:

  • A computerized procedure named Sarah-Pegworks was developed using Visual Basic 6.
  • The system processes data from infrared motion-tracking systems.
  • It identifies movement components and analyzes hand kinematic information.

Findings:

  • Sarah-Pegworks provides numerical and graphic outputs for hand kinematic data.
  • Parameters for data filtering and movement identification were established using data from 55 healthy adults.
