Hypothesis
The study aims to evaluate the test-retest reliability of a clinical procedure measuring trajectories with a haptic handheld stylus in a virtual environment and to establish normative data in healthy subjects.
Conclusion
A new test was developed for recording the kinematics of the handheld haptic stylus in a virtual environment, providing normative data for future assessments.
Supporting Evidence
- The study established normative data for hand trajectories in a virtual environment.
- Test-retest reliability was confirmed with no significant differences between test occasions.
- A learning effect was observed between the first and third test sessions.
Takeaway
Researchers used a special device to track how people move their hands in a virtual world, helping to create a standard for measuring hand movements.
Methodology
Fifty-eight healthy adults performed 3D hand movements in a virtual environment using a haptic device on three occasions within one week.
Limitations
The study only included healthy subjects and may not generalize to individuals with neurological impairments.
Participant Demographics
58 healthy adults, aged 20 to 69, with a mean age of 42.8 years, including 30 females and 28 males.
