This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities. The treatment is often guided by magnetic resonance imaging (MRI); the combination is then referred to as magnetic resonance-guided focused ultrasound. In the clinical setting, HIFU techniques ...
A transcutaneous electrical nerve stimulation (TENS or TNS) is a device that produces mild electric current to stimulate the nerves for therapeutic purposes.TENS, by definition, covers the complete range of transcutaneously applied currents used for nerve excitation, but the term is often used with a more restrictive intent, namely, to describe the kind of pulses produced by portable ...
Unlike deep brain stimulation or Vagus nerve stimulation, which use implants and electrical impulses, TPU is a noninvasive and focused procedure that does not require the implantation of electrodes that could damage the nervous tissue. Its use is applicable in the various fields including but not limited to medical and military science.
A combination of different stimulation frequencies are used (i.e., one fixed at 4 kHz and another within a variable range) to generate frequencies between 4 and 250 Hz which are alleged to more effectively penetrate the soft tissues while producing less discomfort at the skin surface. [18]
A study by a neuroretinologist in the late 1980s suggested that microcurrent stimulation of acupuncture points for the eye had positive effects in slowing and even stopping progression of macular degeneration. [citation needed] This treatment is used to treat both the Wet and Dry forms of AMD. This study was based on Ngok Cheng's research on ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Electrotherapy is the use of electrical energy as a medical treatment. [1] In medicine, the term electrotherapy can apply to a variety of treatments, including the use of electrical devices such as deep brain stimulators for neurological disease. [2]
Electro-stimulation is stimulation using electricity. It can be used in the context of: Animal husbandry as part of the artificial insemination process; Bioelectromagnetics. Cranial electrotherapy stimulation; Transcranial magnetic stimulation; Transcorneal electrical stimulation; Electrical muscle stimulation. Bio-electric stimulation therapy
