Summary
A new device shows potential as a cost-effective tool for measuring trunk reposition sense, demonstrating comparable results to motion capture systems in clinical settings.
Area of Science:
- Biomechanics
- Clinical Measurement
- Spinal Kinematics
Background:
- A need exists for affordable clinical tools to assess trunk reposition sense.
- This study validates a novel device for measuring trunk reposition sense.
Purpose of the Study:
- To evaluate the reliability and validity of a new clinical spine reposition sense device.
- To compare the new device's performance against a gold-standard motion capture system.
Main Methods:
- The study involved three parts with asymptomatic subjects, including repeated trials and test-retest assessments.
- Subjects performed self-determined trunk flexion movements, with angular positions recorded.
- The new device was compared to the Skill Technologies 6D (ST6D) Imperial Motion Capture and Analysis System.
Main Results:
- Intraclass Correlation Coefficient (ICC) for repeated trials (4-7) was 0.79 and 0.76.
- Test-retest reliability (ICC) was 0.38, prompting the use of Bland Altman analysis.
- Bland Altman analysis indicated small measurement differences and comparable results to the ST6D system.
Conclusions:
- The new device may offer a cost-effective method for clinical measurement of sagittal trunk reposition sense.
- Further validation may be needed, but initial findings suggest clinical utility.
