Summary
Mixed reality (MR) object interaction can assess post-surgery wrist fracture recovery. Movement time (MT) with virtual objects correlates with hand function, offering a supplemental assessment method.
Area of Science:
- Rehabilitation Medicine
- Human-Computer Interaction
- Biomechanics
Background:
- Mixed reality (MR) technology is increasingly used for human-object interaction.
- MR devices offer novel methods for assessing hand function, complementing traditional techniques.
Purpose of the Study:
- To compare movement time (MT) for real vs. virtual object manipulation between wrist fracture patients and healthy adults.
- To correlate MT with established hand function indicators.
Main Methods:
- 29 participants (17 patients, 12 healthy adults) performed object manipulation tasks using MR devices.
- Movement times (MT) for real and virtual object tasks were recorded and analyzed.
- Regression models were developed to predict MT based on experimental conditions.
Main Results:
- Patients' surgical hands exhibited significantly longer MTs compared to their non-surgical hands and healthy adults' hands.
- MT showed a negative correlation with grip strength, range of motion, dexterity, and Modified Mayo Wrist Score.
- Regression models effectively predicted MT, indicating potential for tracking recovery.
Conclusions:
- Virtual object interaction effectively reveals hand function characteristics in post-surgery patients.
- MR-based MT assessment can serve as a supplementary tool for monitoring hand function recovery.
- Developed regression models show promise for quantifying hand function progression.
