and may not even form a functional electrical circuit. The wiring in the analysis device is simply used as a mystical conduit. A radionic device does not use or need electric power, though a power cord may be provided, ostensibly to determine a "base rate" on which the device operates to attempt to heal a subject. Typically, little attempt is made to define or describe what, if anything, is flowing along the wires and being measured. Energy in the physical sense, i.e., energy that can be sensed and measured, is viewed as subordinate to intent and "creative action". Claims about contemporary EMT devices are similar to those made by the older generation of "radionics" devices, and are also not supported by evidence and are also pseudoscientific. Even though some of the early works in bioelectromagnetics have been applied in clinical medicine, there is no relationship between alternative devices or methods that use externally applied electrical forces and the use of electromagnetic energy in mainstream medicine. The American Cancer Society says that "relying on electromagnetic treatment alone and avoiding conventional medical care may have serious health consequences". In some cases the devices may be ineffective and harmful. Reviews Several systematic reviews have shown EMT is not a useful therapy: In 2009 no significant difference from control was found for management of pain or stiffness for osteoarthritis. In 2011 a systematic literature review on the use of pulsed electromagnetic field (PEMT) body mats used in a wide range of conditions found insufficient evidence for them to be recommended and recommended further high‐quality, double‐blind trials. In 2014 insufficient for the efficacy of EMT as a therapy for urinary incontinence. In 2014 EMT was found to have no difference from control for stimulation of bone growth in acute fractures. In 2015 Cochrane Database of Systematic Reviews found no evidence that EMT was useful in healing pressure ulcers or venous stasis ulcers. A 2016 guideline, in addition to reviews in 2016, 2013 and 2022, did not find EMT useful for various forms of pain. EMT devices The FDA has banned some commercially available EMT devices. In 2008 the VIBE machine from Vibe Technologies had a Class I recall that was completed in 2012. Other ineffectual EMT therapy devices that have been marketed include: "BioResonance Tumor Therapy", developed by Martin Keymer and purported to stimulate the P53 gene to cure cancer.
