In 2009 no significant difference from control was found for management of pain or stiffness for osteoarthritis.[20] 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.[21] In 2014 insufficient for the efficacy of EMT as a therapy for urinary incontinence.[22] In 2014 EMT was found to have no difference from control for stimulation of bone growth in acute fractures.[23] In 2015 Cochrane Database of Systematic Reviews found no evidence that EMT was useful in healing pressure ulcers[24] or venous stasis ulcers.[25] A 2016 guideline, in addition to reviews in 2016 and 2013, did not find EMT useful for various forms of pain.[26][27][28]
