Ultrasound (US) is a mechanical (not electrical) form of energy, and therefore, strictly speaking, it is not really electrotherapy at all, but it falls into electrotherapy. Ultrasound is applied using the head of an ultrasound probe that is placed in direct contact with your skin via a transmission coupling gel. this probe is having electricity as a basic source of energy, which is being converted into mechanical forms into sound or we can say waveforms energy. The sound energy is known as mechanical vibration at increasing frequencies.  The normal range of human sound is from 16 Hz to something close to 15-20,000 Hz (in kids and young adults). Beyond that upper limit, the ultrasound is known as the mechanical vibration. Usually, the frequencies used in therapy vary from 1.0 and 3.0 MHz (1 MHz= 1 million cycles per second). Sound waves are longitudinal waves consisting of compression and rarefaction zones. Particles of material will oscillate about a fixed point wh

Fibromyalgia, also sometimes called fibromyalgia syndrome (FMS), is a long-term condition that causes pain all over the body in a specific way.  fibromyalgia  is a noninflammatory, nondegenerative, nonprogressive disorder, still, several factors may affect the severity of symptoms.  Fibromyalgia is the second most common condition affecting your bones and muscles with pain and still, it is often misdiagnosed and misunderstood. classic symptoms of fibromyalgia are muscle and joint pain and fatigue with less activity. symptoms of fibromyalgia are, fatigue (extreme tiredness) increased sensitivity to pain headaches trouble sleeping (nonrestorative sleep) dry eyes depression anxiety pain or a dull ache in the lower belly sleeping for long periods without feeling rested  bladder problems(like interstitial cystitis) trouble focusing or paying attention In people with fibromyalgia, the brain and nerve activities are interpreted thus it may misinterpret or overreact to nor
