Designing a non-restrictive torso stabiliser for individuals with spinal cord injury to enhance mobility and prevent falls.
Resumo
The content discusses the development and preliminary evaluation of a mechanical torso stabiliser for individuals with spinal cord injuries. The paper focuses on the need for a device that offers transparent support during daily activities while providing compliant blocking in case of a fall. The design is inspired by centrifugal clutches and seat-belt mechanisms to ensure simplicity, robustness, and cost-effectiveness. The study includes simulation-based parameter identification, device development, and validation through MoCap experiments. The prototype aims to improve torso stability and enhance quality of life for patients with spinal cord injuries.
I. Introduction
- Spinal cord injuries (SCIs) impact torso stability, affecting daily living activities.
- Existing devices like lateral trunk supports and TLSO have limitations.
II. Simulation-Based Parameter Identification
- MoCap experiments were conducted to identify device characteristics.
- The cable-based device requires 55-60 cm of unrestricted travel and a velocity threshold for blocking.
III. Device Development and Validation
- The prototype includes transparent and blocking modes for non-restrictive movement and fall prevention.
- MoCap validation demonstrates the device's ability to track movements and trigger compliant blocking.
IV. Conclusion
- The mechanical device addresses torso stabilization challenges for individuals with SCI.
- Further work is needed to fine-tune the blocking mechanism and validate with a broader population.
Estatísticas
The simulated evaluation resulted in the cable-based device to require 55-60 cm of unrestricted travel.
The device requires a cable linear velocity threshold of 80-100 cm/s to trigger the blocking mechanism.
