Spinal cord injury (SCI) is the most serious complication of spinal cord injury, often leading to severe dysfunction of the limbs below the injured segment
Spinal cord injury (SCI) is the most serious complication of spinal cord injury, often leading to severe dysfunction of the limbs below the injured segment
Neuromuscular stimulation triggered by electromyography has proven to be an effective treatment for stroke recovery
In this work, a robotic rehabilitation system is proposed, where the robot assists to replace electrical stimulation
Skeletal robot
The EMG control interface is designed for six control modes: four single degrees of freedom (corresponding to the active degrees of freedom of the exoskeleton) and two multiple degrees of freedom
Record EMG signals from the eight muscles that control the movement of the elbow, forearm and wrist: biceps (BB), triceps (TB), pronator teres (PT), supinator (S), radial Lateral flexor carpi (FCR), extensor carpi ulnaris (ECU), extensor carpi radialis longus (ECRL) and flexor carpi ulnaris (FCU)
The MAHI Exo II exoskeleton is equipped with adjustable weights for passive gravity compensation of the elbow joint
EMG
The classifier based on EMG can classify the user's expected movement direction with high accuracy in different modes
The research results encourage the further development of the electromyographic control interface of the rehabilitation robot
Using EMG to control exoskeleton in real time shows the application prospects of the system, especially in simple single-degree-of-freedom direction classification tasks
