Browsing new clinical trials today and this one is recruiting. Seems to be laser therapy done with a device at home. Just sharing 

The Erchonia® THL™ is made up of (2) 405-nanometer violet laser diodes mounted in a portable handheld device. The diodes are positioned approximately 4 inches from the skin and applied in a continuous back and forth sweeping motion from the top of the ear down the side of the neck. The treatments will be self-administered by the subject at his or her's place of residence, once per day for 28 days. Each procedure administration lasts 5 minutes per ear, for a total of 10 minutes.
