Introduction to Biofeedback Technology

Let’s introduce the basic information of biostimulation feedback instrument. First of all, what is biofeedback? It refers to the use of instruments to record and preserve physiological activities that are normally difficult for people to realize, such as ECG, EMG, skin temperature, blood volume pulsation, etc., and transform them into intuitive, easily understood visual and auditory forms. Patients can understand their own physiological changes based on these signals and make conscious changes to improve physiological changes in the direction of certain goals. The feedback instrument can show the process of improvement, affirming and reinforcing the correct response of the patient. The biofeedback instrument works by combining biofeedback technology and electrical stimulation methods to gradually restore central control of paralyzed muscles by applying passive electrical stimulation to muscles or electrical stimulation triggered by the patient’s active contraction, providing a large number of proprioceptive muscle contraction input impulses to the central nervous system, promoting the reconstruction of damaged neural pathways and the recovery of muscle function. By collecting, analyzing and training the surface electromyography (EMG) of the patient, electrical stimulation can be applied to the patient’s muscles to help diagnose and restore the patient’s muscle dysfunction. The function of biofeedback instrument is mainly divided into two parts: assessment and treatment. The assessment function can be divided into: muscle strength and muscle tone assessment (that is, the original clinical common manual rough characterization of muscle strength and muscle tone several levels, now we can assess the accurate data through this instrument.) Evaluation of cerebral palsy (early detection of children at risk through biofeedback instrument) evaluation of slant neck (can evaluate muscle strength and spasticity of both sides) evaluation of adult lower back pain, evaluation of swallowing difficulty, evaluation of knee bone sign group. Treatment functions can be divided into three treatment modes: neuromuscular electrical stimulation, myoelectric triggered electrical stimulation and multimedia biofeedback. For example, the biofeedback mode includes relaxation training, endurance training, precision training, and coordination training (e.g., this mode can be used for children with hand-eye incoordination). Finally, the indications for this device are: motor dysfunction due to central nervous system pathology (such as cerebral palsy, spinal cord injury), disuse muscle atrophy due to loss of innervation of lower motor neurons (such as brachial plexus nerve injury, peroneal nerve injury, etc.), and limitation of movement after bone and joint injury or orthopedic surgery. We hope that patients with such needs can come to the Department of Pediatric Rehabilitation for treatment. In conclusion, the development of pediatric rehabilitation cannot be achieved without the support and help of everyone. Thank you all!
