Pulsed electromagnetic field therapy (PEMFT), also called pulsed magnetic therapy, pulse magnetotherapy, or PEMF, is a reparative technique most commonly used in the field of orthopedics for the treatment of non-union fractures, failed fusions, congenital pseudarthrosis and depression. In the case of bone healing, PEMF uses directed pulsed magnetic fields through injured tissue. This is believed to stimulate cellular repair. The FDA has approved several such stimulation devices. These devices provide a complementary solution that may aid in bone repair. == History == Although electromagnetic therapy became widely adopted in Western Europe, its use was restricted to animals in North America. Veterinarians became the first health professionals to use PEMF therapy, usually to heal broken legs in racehorses. Professional sports doctors then decided to experiment with veterinarian devices off label on professional athletes which ultimately led to legally licensed devices for human use in the United States - but under strict stipulations that it was only to be used for non-union bone fractures under a medical prescription from a licensed doctor. In 1979 the FDA approved non-invasive devices using pulsed electromagnetic fields designed to stimulate bone growth.〔(【引用サイトリンク】publisher=Blue Cross & Blue Shield of Mississippi )〕 In 2004, pulsed electromagnetic field system was approved by FDA as an adjunct to cervical fusion surgery in patients at high risk for non-fusion.〔 On 10/13/2015 the FDA reclassified PEMF devices from their existing Class 3 category to a Class 2 status. This change reduces the regulatory burden on manufacturers of PEMF devices that request FDA clearance to market their devices. Today, there is a wide variety of professional and consumer PEMF devices that are sold on the internet as wellness devices. The companies that sell and manufacture them make no claims as to their effectiveness mainly to bypass medical device regulations and approvals.〔(【引用サイトリンク】 title=FDA Executive Summary - Orthopaedic and Rehabilitation Devices Panel )〕 They often consist of full body mats and pillows that contain coils of wire that are energized by controller units that will "pulse" magnetic fields through the body. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pulsed electromagnetic field therapy」の詳細全文を読む スポンサード リンク
