Area of Science:

  • Rehabilitation Engineering
  • Biomechanics
  • Human-Computer Interaction

Background:

  • Grip assessment is crucial for daily activities but currently relies on subjective methods.
  • Lack of objective quantification equipment hinders accurate evaluation of grip movements.

Purpose of the Study:

  • To develop, validate, and test a virtual environment for analyzing various grip and pinch movements.
  • To introduce objective quantification equipment for grip strength and range of motion.

Main Methods:

  • A virtual environment controlled by five trigger devices equipped with sensors and electronic circuits.
  • Validation involved 20 children assessed by three specialist physical therapists.
  • Testing included children with and without mild upper limb motor abnormalities.
