Summary
This study introduces a novel dynamic head and neck brace for pain treatment, offering adjustable support and assessing neck stiffness. The device enables precise movement and traction, improving diagnostic capabilities for head and neck disorders.
Area of Science:
- Rehabilitation Engineering
- Biomedical Devices
- Orthopedics
Background:
- Existing rehabilitation devices for head/neck pain lack dynamic adjustability and diagnostic capabilities.
- Current treatments are limited in providing simultaneous support, dynamic positioning, and patient condition assessment.
Purpose of the Study:
- To design and implement a novel dynamic head/neck brace.
- To provide static and dynamic support/traction in various positions.
- To assess head/neck stiffness for diagnosing disorders.
Main Methods:
- Developed a dynamic head/neck brace with static and dynamic support/traction capabilities.
- Evaluated the device's range of motion and symmetric traction using two control modalities.
- Assessed head/neck stiffness using a simulated mechanical model with springs.
Main Results:
- The brace achieved precise lateral bending (-6.97° to 7.02°) and flexion/extension (-8.10° to 8.12°) with high accuracy (99.42%-99.89%).
- Symmetric traction tests showed minor deviations (<0.34° mean error) compared to calculations, with greater deviations in flexion/extension.
- Stiffness measurement accuracies for the mechanical model reached 99.78% and 99.96%.
Conclusions:
- A novel dynamic head/neck brace was designed and implemented.
- The device offers versatile support and traction, adaptable to various head/neck positions.
- The brace effectively evaluates head/neck stiffness, aiding in the diagnosis of cervical disorders.
