Summary
This study introduces a computer system for analyzing finger forces during hand function. The system aids in evaluating neurological patients by measuring grip strength and continuous force over time.
Area of Science:
- Rehabilitation Engineering
- Neuroscience
- Biomechanics
Background:
- Hand function analysis is crucial for neurological patient assessment.
- Routine clinical examinations often lack detailed analysis of finger muscle forces.
- Objective measurement of voluntary muscle contraction forces is needed.
Purpose of the Study:
- To describe a microcomputer-controlled system for measuring and analyzing finger forces.
- To develop a user-interactive system for clinical and experimental use.
- To facilitate objective hand function analysis in neurological patients.
Main Methods:
- A Z80-based microcomputer system was developed.
- Commercial high-precision force transducers and custom amplifiers were utilized.
- Menu-driven, user-interactive programs were created for various tasks.
Main Results:
- The system measures maximum hand grip force.
- Continuous recording of forces as a function of time is possible.
- Task parameters and feedback are user-configurable for flexibility.
Conclusions:
- The described system offers a valuable tool for analyzing hand functions.
- It enables objective assessment of finger forces in clinical settings.
- The system's flexibility supports diverse research and clinical applications.
