A Wearable Body Controlling Device for Application of Functional Electrical Stimulation

Area of Science:

• Biomedical Engineering
• Veterinary Neurology
• Robotics

Background:

• Spinal cord injuries in dogs often lead to hindquarter paralysis and impaired mobility.
• Current rehabilitation methods may lack targeted support for restoring independent locomotion.
• Functional electrical stimulation (FES) shows promise for muscle reanimation but requires precise control and stabilization.

Purpose of the Study:

• To develop and validate a novel bionic test-bed for canine spinal cord injury research.
• To create a balancing device utilizing inertial measurement sensing and leg actuation for hindquarter stabilization.
• To lay the groundwork for advanced muscle control strategies using direct functional electrical stimulation (FES).

Main Methods:

• Designed and constructed a bionic test-bed mimicking canine gait dynamics.
• Integrated inertial measurement sensors for real-time motion analysis.
• Developed and tested control algorithms for direct leg actuation and stabilization.
• Analyzed various muscle stimulation and balancing strategies on the robotic platform.

Main Results:

• The bionic test-bed successfully replicated canine walking gaits for device development.
• Experimental results demonstrated the balancing device's effectiveness in sensing and motion control.
• The system provided stabilization for a simulated canine hindquarter paralysis scenario.
• The device showed potential for veterinarians to tailor stimulation parameters for individual dogs.

Conclusions:

• The developed balancing device and robotic test-bed are effective tools for canine spinal cord injury rehabilitation research.
• This technology offers a viable approach to stabilizing paralyzed hindquarters in dogs.
• The findings support the future application of FES-guided stabilization for restoring canine mobility.
