In modern medicine, the method of studying and applying natural or artificial physical factors to the human body and achieving the purpose of health care, prevention, treatment and rehabilitation through physiological regulation mechanisms such as human nerves, body fluids, endocrine and immunity is called physical therapy or physical therapy, or physical therapy for short.
After the muscles lose their innervation, they will lose the ability to actively contract. It is a slow paralysis. Before the nerves are reinnervated, passive protection measures should be taken to keep the muscles in a "healthy" state, delay muscle atrophy, improve blood circulation and local nutritional status, and create good conditions for nerve regeneration. Once the nerves are reinnervated, the muscles are more likely to recover their functions. Using a nerve injury therapeutic device can achieve the above treatment purposes. The pulse current output by the instrument can directly excite the denervated muscles. Reduce muscle fiber degeneration and slow down muscle denervation atrophy. Promote blood flow and maintain muscle nutrition. Promote hypertrophy and strengthening of denervated muscles and re-innervated muscle fibers, and improve muscle tension.
At the same time, the stimulation signals received by the sensory nerve endings are transmitted to the central nervous system, triggering a series of bioelectric activities in the lesion site, which promotes the recovery of the patient's normal motor function and the development of nerve tissue.
Introduction to nerve injury therapeutic instrument
Nerve injury therapeutic instrument is also known as neuromuscular electrical stimulator. Neuromuscular electrical stimulation therapy (NMES for short) is a method of using low-frequency pulse current to stimulate muscles to contract in order to restore their motor function. The clinical application of NMES has a history of more than 100 years. In recent years, the application of NMES in the rehabilitation of neuromusculoskeletal diseases has increased.
Nerve injury therapeutic instrument uses low-frequency pulse current to stimulate denervated muscles, reduce muscle fiber degeneration, slow down muscle denervation atrophy, promote blood flow and maintain muscle nutrition, promote hypertrophy and strengthening of denervated muscles and re-innervated muscle fibers, and can improve muscle tension.
A large number of animal and human experiments have proved that after muscles are electrically stimulated to contract, muscle fibers thicken, muscle volume and weight increase, capillaries in muscles become abundant, aerobic metabolic enzymes such as succinate dehydrogenase (SDH) and adenosine triphosphatase (ATPase) increase and become active, slow muscle fibers increase, and fast muscle fibers change to slow muscle fiber characteristics.
Therapeutic effect of nerve injury therapeutic device
1. Disuse muscle atrophy: A large number of studies have shown that NMES cannot completely prevent but delay atrophy and can enhance the strength of atrophied muscles.
2. Increase or maintain ROM: NMES, as an auxiliary treatment method, can increase or maintain ROM. The mechanism of action is to stimulate muscle contraction, cause joint movement, and pull the soft tissue around the joint.
3. Muscle relearning and facilitation: Nerves are plastic, that is, the nervous system can constantly adapt to changes in the environment.
4. Promote the recovery of denervated muscles: Its purpose is to use electrical stimulation to make muscles contract and maintain them in a "healthy" state.
