Exoskeletis s are ayable robotic devices designed to o assitt and enhance human movement. They are incremenaly used in stroke rehabilitation to help patients regain mobility and clarth. A key accessment of these systems is te of elektromyographie (EMG) signals, which mesticure muscle activity.

What Are EMG- Based Control Systems?

EMG- based control systems utilize electrical signals generated by muscle contractions. Sensors placed on th skin detect these signals, which are then processed to interpret thee user 's intended movements. This allows the exoskeleton to respond naturally and assistively, making rehabilitation more effective.

How Do EMG Sensors Work?

EMG sensors detect electrical activity produced by muscle fibers during contraction. When a patient approct ts to move, these sensors pick up these signals. Thee system then analyzes thee amplitee and pattern of thee signals to determinate thee movement intent.
