This Machine gives a noninvasive treatment in which sound waves are used to penetrate soft tissues, increasing blood flow. When tissue is exposed to ultrasound, the sound waves cause a micro-vibration within the tissue. This vibration creates heat energy that increases blood flow to the area. This increased blood flow causes an increase in oxygen and chemicals that are essential for healing of the damaged tissue. This can help relieve pain, improve circulation, and promote tissue healing.Ultrasonic with Dual Channel TENS delivers you the best combination of electrotherapy and heat therapy thereby making it extremely helpful for pain management and ideal for physiotherapy. It efficiently helps your nervous system to block out pain in the cerebral lobes, thereby making your therapy sessions a lot better. Arthritis, a few cerebral issues, knee pain, back pain or even labour pain, this machine can dull it all!!.
