Vibration: Ultrasonic vibration and the warming effect can increase blood circulation in the local area. Increases heat in tissues • Increases blood flow • Enhances absorption by cells (e.g. of medicinal ingredients) • Decreases " trigger point" pain • Aids recovery from fatigue • Accelerates wound healing • Increases elasticity of collagen tissue • Relaxes, eases joint stiffness • Relieves muscular spasm • Promotes reduction in inflammation • Use for more serious illnesses where ultrasound therapy recommended by physician.

Heat: Heat accelerates blood circulation and promotes fluid exchange. The heat is produced by friction of the molecules vibrating at high speed. To healthy cells, heat supplies energy and speeds metabolism, while it increases the breakdown of compromised tissue. However, to protect healthy cells, most medical and beauty ultrasonic devices have a maximum output, and have an auto shut-off after a certain time. Also, it is recommended the massage head be kept in constant motion. The aim is to rejuvenate healthy cells and harm no body tissues.

Cavitation: The ultrasound exerts an effect like micro-massage and excites the body tissues Cavitation is a recognized occurrence in the tissues during ultrasound stimulation. It is the formation of very tiny bubbles (only a micron or so in diameter) of gas in the fluids in body tissues. Using pulsed ultrasound vibration reduces the tendency to "collapse" cavitation (tissue-damaging due to high pressure and temperature changes) and produces mostly "stable" cavitation, where the tiny bubbles oscillate within the ultrasound waves but remain intact. This kind of cavitation is associated with "acoustic streaming", which exerts viscous stress on the cell membrane and thus may increase membrane permeability, bringing therapeutically useful changes.   ULTRASONIC WAVES IMPORTANT: Please use Ultrasonic Massagers according to product directions. Keep your Ultrasonic Massager moving. Do not apply in one place for too long a time.   3 MHz ULTRASOUND FOR SMALL MUSCLES Use 3 million vibrations per second to work on smaller muscles, such as those of the face. 1 MHz ULTRASOUND FOR AVERAGE MUSCLES Use 1 million vibrations per second to work on medium sized muscles such as in the limbs, neck, and shoulders... 0.5 MHz ULTRASOUND FOR LARGE MUSCLES Use 0.5 million vibrations per second to work on the largest muscles of the legs and back... Ultrasound Therapy  The development of ultrasound  Research on ultrasound began at the start of the First World War (1914), when the Allied forces used it to detect Germany submarines. Except for military purposes, it was only used for underwater research - until 1927, when the United States began to use ultrasound in bio-chemical research. In 1928, using ultrasoun, the eastern Germans ran experiments to attempt curing loss of hearing and otosclerosis, and by 1939, ultrasonic therapy was born. Although ultrasonic development was interrupted by the Second World War, the UK, among other countries, actively refined ultrasonic therapy for rehabilitative purposes in postwar years. What is Ultrasound?  Sound is transformed like a wave, with different sizes and densities; different waves emit high and low sounds. The human's hearing range is from 20 to 18000Hz. The higher the Hz is, the higher the tone we hear. Like the strings of a violin, the thinnest one always produces the highest sound. Ultrasound is undetectable to humans. In engineering, any rate over 20000Hz is called ultrasound, i.e. the threshold above 20000 vibrations per second. To our hearing, ultrasound is inaudible, but to many animals, it is heard clearly. For example, a bat can respond to 20 thousands to 200 thousands Hz of ultrasound. A dolphin or whale can also discriminate between hundreds of thousands Hz of ultrasound. If ultrasound means nothing to our sense of hearing, what can we do with it? We can take the advantage of its density and speed in more subtle methods. First of all, we must know exactly how ultrasound can benefit us.

To test it, place a drop or two of water on the metal head of the Ultrasonic Massager, then press 'Power' switch to turn on. You will see how the water is broken into tinier and tinier droplets by the action of micro-vibration. IN PROFESSIONAL THERAPISTS' HANDS Ultrasound is often used by Chiropractors and Doctors with the aim of accelerating blood circulation in the local area, sport injury recovery, pain relief, reduction in inflammation and muscular spasms, and increased absorption of analgesics or anti-inflammatories.
