The CPM + EMG + EMS program delivers a comprehensive therapy combining Continuous Passive Motion (CPM), Electromyography (EMG) biofeedback, and supportive Electrical Stimulation (EMS). This integration ensures highly effective, patient-driven rehabilitation that actively engages the patient while reinforcing weakened muscle structures with an external electrical pulse.

Key Feature: EMG-Triggered Movement with Stimulation

The extension remains locked in place until the patient generates a voluntary muscle contraction that exceeds a preset threshold. Once this target value is reached, the device executes the programmed movement cycle while simultaneously delivering a synchronized EMS pulse to support the contraction and facilitate full range of motion.

In this dual-channel application, the system operates based on the alternating activation of antagonist muscles (e.g., wrist flexors and extensors). This means that each EMG/EMS channel is assigned to a different muscle group, and both stimulation and motion occur sequentially – the activation of one group triggers movement in a specific direction, followed by a directional shift tied to the activation of the opposing muscle.

Configuration Parameters:

• Triggering Threshold (Threshold): The target muscle tension (measured in microvolts), configured independently for each EMG channel, required to initiate both device movement and stimulation.

• Electrostymulation Parameters (EMS): Full configuration of the electrical pulse, including frequency, pulse width, and individual intensity (amplitude) adjusted independently for each of the two channels.

• Range of Motion (ROM): The defined angular limits of the joint’s movement, with movement phases mapped to specific channels.

• Pauses: Adjustable rest intervals between consecutive muscle contraction, relaxation, and stimulation phases at terminal positions.

• Session Length: Total duration of the exercise session.

• Movement Speed: The velocity of the movement of the extension during the motion phase.
