What is Therapeutic Ultrasound?
Scientists refer to the number of vibrations per second as the frequency of the sound, and its unit is Hertz (Hz). The frequency of sound waves that we can hear in human ears is 20 Hz to 20,000 Hz. When the vibration frequency of the sound wave is less than 20 Hz or greater than 20,000 Hz, we will not hear it. Therefore, we call sound waves with frequencies above 20,000 Hz "ultrasonics". The ultrasonic frequency commonly used for medical diagnosis is 1 megahertz to 10 megahertz which can be used for ranging, industrial flaw detection, cleaning, welding, drilling, crushing, sterilization and so on.
Ultrasound emits small sound waves at an extremely high frequency that is out of the range of human hearing. When applied to problem areas in soft tissues and joints, it produces heat that helps reduce inflammation and increase blood flow, in addition to decreasing pain, stiffness, and spasms. Therapeutic ultrasound is also believed to have a positive effect on the healing process.
The use of ultrasonic waves in the human tissue has good penetrability, directionality and energy stacking characteristics, the use of ultrasonic warming effect, mechanical effects and physical and chemical effects, massage loosening adhesion and health effects.
The frequency of the ultrasonic energy meter is 1 megahertz (1 million Hz / s), the direction being accurate, and the penetration being strong. Through the three major effects of sound waves (mechanical, warm, physical and chemical effects) on various parts of the human body, to achieve the role of massage relaxation.
Principle of ultrasound therapy
1.Mechanical function: the ultrasound have the [micro massage" to the tissue substance and tiny cell. It could soften tissue, enhance penetration, improve metabolism, promote blood circulation, stimulate nerve system and cell, relief pain.
2.Heating function: it forms heat during ultrasound therapy, so it is also called as"ultrasound diathermy therapy". it is deep heating, that penetrate below the muscle. Thus, ultrasound therapy is applied to chronic soft tissue pain, arthritis, rheumatism.
3.Physical therapy function: based on the mechanical and heating function, it will trigger physical therapy.
a)Hydrogen ion concentration changes: inflammation tissue accompanied by acidosis phenomenon, the ultrasound can make the pH value changes to the alkaline, so that the symptoms are reduced, good to inflammation repair.
b)Effects on enzyme activity: ultrasound can depolymerize complex proteins into common organic molecules, affecting the activity of many enzymes.
c)Under the action of high-intensity ultrasound, many highly active free radicals can be formed in the tissue. They can accelerate the redox process in the tissue and accelerate the growth process.
How Does Therapeutic Ultrasound Work?
While its effects and goals are different from ultrasound screening technologies, ultrasound therapy is implemented in much the same way. The process may be familiar if you've ever had an ultrasound screening in the past.
An ultrasound emitting probe will be passed over your skin across the pain point or injury. We will apply ultrasound gel to your skin to reduce friction and allow for better transmission of the ultrasound waves. Despite the deep-tissue heat applied during the therapy, you typically will feel little or no heat at all.
