EMG Biofeedback Stimulation Device is a combination of conventional electromyographic biofeedback and neuromuscular electrical stimulation. It uses an electromyographic biofeedback device to amplify the bioelectrical activity of muscle tissue, which is normally unconscious, and convert it into perceptible visual and auditory signals. These signals are then transmitted back to the brain through organs such as the eyes and ears (i.e., feedback). This allows the body to autonomously train and control the bioelectrical activity of muscle tissue based on these signals, achieving the training goal.
EMG Biofeedback Stimulation Device is a portable functional electrical stimulator that integrates surface electromyography, electrical stimulation, triggered electrical stimulation, assisted electrical stimulation and multimedia biofeedback training. It can train the motor function of patients' paralyzed limbs through electrical stimulation.
Electrical stimulation mode: Set different frequencies, pulse widths and other parameters according to clinical needs to customize personalized treatment plans.
Triggered mode: When the patient contracts the muscles forcefully and the generated electromyographic signal reaches the threshold, the stimulator will generate electrical stimulation.
Power-assisted mode: When the patient contracts the muscles forcefully, the stimulator will generate electrical stimulation, and the intensity and duration of the stimulation will change synchronously with the electromyographic signal.
EMG detection mode: Surface EMG monitoring, displaying maximum, minimum and average values, and objective quantification.
Game mode: Strength training, endurance training and coordination training.
Clinical Applications
EMG Biofeedback Stimulation Device is used to strengthen the muscles of hemiplegic stroke patients. The muscles stimulated are generally the elbow extensors and wrist dorsiflexors in the upper limbs, and the ankle dorsiflexors and tibialis anterior in the lower limbs. Because most patients experience spasticity in the upper limb flexors and lower limb extensors after a stroke, this treatment aims to counteract incorrect movement patterns and induce corrective ones.
Muscle Excitability Feedback Training: This therapy aims to empower patients to consciously increase muscle tone and function in affected muscles, preventing muscle atrophy and restoring the contractile function of relaxed muscles. It is commonly used for post-stroke conditions such as foot drop, wrist extension, and finger extension difficulties. EMG biofeedback training can enhance muscle function and improve symptoms.
Muscle Relaxation Feedback Training: The appropriate muscles are selected for treatment based on the patient's condition. Skin electrodes of the EMG biofeedback device are placed on the belly of the muscle with excessive tension. The trainer continuously encourages the patient to consciously relax the muscles to reduce tension in the affected muscle.
