Summary
This study developed a virtual grip assessment system using trigger devices. The system accurately quantifies grip and pinch movements, aiding therapeutic strategy selection.
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.
Main Results:
- The developed system demonstrated an 86.6% agreement with expert physical therapist evaluations.
- The system provided efficient and reliable results for assessing grip and pinch movements.
- The technology effectively captured grip strength and range of motion parameters.
Conclusions:
- The virtual grip assessment system offers an objective and reliable method for evaluating hand function.
- This technology can significantly aid in assessing grip and pinch movements.
- Facilitates informed decisions for therapeutic intervention strategies in rehabilitation.
