What is the role of ultrasonic therapy

Many diseases require physical therapy during the recovery period to help patients recover after surgical treatment. Among the many physical therapy methods, ultrasound physical therapy is the most effective one. It is also a new disease physical therapy method that has emerged in recent years. Therefore, many people do not understand the specific effects of this physical therapy method. So, what does ultrasound therapy do?

First, what is the role of ultrasound therapy? The method of applying ultrasound to the human body to achieve therapeutic purposes is called ultrasound therapy. The scope of application of ultrasound therapy is becoming increasingly wide, far exceeding the original general therapies in physical therapy, such as ultrasound cancer treatment, urinary lithotripsy and applications in stomatology. Therefore, the concept of ultrasound therapy should be divided into two categories: broad (including various special ultrasound therapies) and narrow (referring to the non-destructive dose therapy commonly used in physical therapy).

Second, ultrasound acts on human tissues to produce mechanical, thermal and cavitation effects, which lead to accelerated blood flow in local tissues, improved blood circulation, increased peristalsis of blood vessels, enhanced cell membrane permeability, redistribution of ions, vigorous metabolism, reduced hydrogen ion concentration in tissues, increased pH value, enhanced enzyme activity, enhanced tissue regeneration and repair capacity, muscle relaxation, decreased muscle tension, and reduced or alleviated pain. The changes in local tissues during ultrasound therapy can affect a certain stage of the body or the whole body through neurohumoral pathways, thus playing a therapeutic role.

What is the role of ultrasound therapy? Small doses of ultrasound can increase nerve excitability, speed up conduction, reduce nerve inflammatory response, promote nerve healing, increase pain threshold, and relieve pain. Therefore, it has a significant analgesic effect on peripheral nerve diseases such as neuritis and neuralgia. Large doses of ultrasound acting on peripheral nerves can cause vascular paralysis, tissue cell hypoxia, and subsequent necrosis. The central nervous system shows a high sensitivity to ultrasound. Within a certain dose, ultrasound has the following effects on the central nervous system: acting on the brain can stimulate cellular energy metabolism, dilate cerebral blood vessels, accelerate blood flow, accelerate the establishment of collateral circulation, and accelerate the recovery of brain cell function; acting on the diencephalon can increase heart rate and blood pressure; acting on the spinal cord can change sensory and motor nerve conduction.
