Low intensity pulsed ultrasound has been proposed as a therapy to support bone healing after fractures, [1] osteomies, or delayed healing. A 2017 review, however, found no trustworthy evidence for the use of low intensity pulsed ultrasound for bone healing, mostly based on the large pragmatic randomized controlled trial published in 2016.
They discovered that this low-power ultrasound is able to stimulate high neuron activity which allows for the manipulation of the brain waves through an external source. 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 ...
Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.
Pulsed electromagnetic field therapy (PEMFT, or PEMF therapy), also known as low field magnetic stimulation (LFMS) is the use of electromagnetic fields in an attempt to heal non-union fractures and depression. [1] By 2007 the FDA had cleared several such stimulation devices. [2]
Ultrasound is sound with frequencies greater than 20 kilohertz. [1] This frequency is the approximate upper audible limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound. Ultrasonic devices operate with frequencies from 20 kHz up to several gigahertz.
Low-intensity extracorporeal shock wave therapy has been used as a treatment for erectile dysfunction. [23] It differs from palliative options by aiming to restore natural erectile function by inducing cellular microtrauma, triggering the release of angiogenic factors and promoting neovascularization in treated tissue. This mechanism is ...
Bone stimulation with either electromagnetic or ultrasound waves may be suggested as an alternative to surgery to reduce the healing time for non-union fractures. [ 46 ] [ 47 ] The proposed mechanism of action is by stimulating osteoblasts and other proteins that form bones using these modalities.
One possible way is the use of an implantable transcranial Doppler device "operatively connected to a drug delivery system". [7] Battery-powered, it would use an RF link to a portable computer running a spectral analysis routine together with input from an oximeter (monitoring the degree of blood oxygenation, which a stroke might impair) to ...
