Principles Of Electromyographic Biofeedback Therapy
1. Surface electromyography
It is a simple, non-invasive, safe, and easy to operate evaluation model. By observing muscle activity in real-time, evaluating and measuring electromyography, analyzing functional impairments, muscle tone levels, fatigue levels, etc., neuromuscular assessment and rehabilitation guidance can be carried out. Create accurate data on muscle electromyography levels.
2. Electrical stimulation
The electromyographic biofeedback device adopts a frequency conversion low-frequency electrical stimulation mode, and prescription selection treatment is carried out according to the plan. It has a significant intervention effect on early stroke and cerebral palsy, can excite nerves and muscles, enhance muscle strength, and prevent disuse induced muscle atrophy. It is also possible to customize scenario modes for adjusting different stimulus parameters and customizing treatment modes. TENS therapy can also be used for pain relief treatment.
3. Inducing electrical stimulation
Mainly used for mid-term or late stage rehabilitation treatment of patients, to collect weak electromyographic signals during muscle contraction and display images through instrument amplifiers, allowing patients to observe the muscle activity level of their diseased muscles. Adopting a threshold stimulation mode, a corresponding threshold is set for the electromyographic signal when the patient is exercising hard. When the electromyographic signal value reaches the threshold when the patient is exercising hard, the device outputs current stimulation for one-time electrical stimulation. Causing functional activities.
4. Template training
Provide multiple treatment templates for free selection, conduct functional training according to the template direction, maintain electromyographic signals, and achieve training effects.
5. Multimedia feedback
The electromyographic biofeedback device converts electromyographic levels into multimedia games, providing patients with scenario interaction models for different training purposes and scenarios. By providing patients with a visual understanding of the muscle control training process, it helps them train their muscle relaxation ability, endurance, control ability, accuracy, and coordination, thereby improving the fun and compliance of training.
6. Induced electrical stimulation
Mirror therapy is commonly used for the recovery of motor function after stroke or spinal cord injury. It collects the patient's electromyographic signals, extracts the healthy side electromyographic signals through equipment processing, and generates low-frequency electrical stimulation based on the electromyographic signals. Through electrodes, the affected side muscles are induced to contract, achieving the function of promoting healthy side exercise training. Due to the complex connections of the brain neural network, some motor nerves start from the healthy side and extend to the affected side. These motor pathways play a crucial role in the recovery of motor function in the affected limb. During the electrical stimulation process, patients can undergo bilateral motor training with the assistance of equipment. When symmetrical movements are performed on both limbs, the motor cortex area is widely activated, facilitating partial motor pathways on the affected side and promoting the recovery of limb motor function. For patients with spinal cord injury, upper and lower limb functional exercise can also be achieved.
