Low Level Laser Therapy (aka cold laser) is a well-established therapy for pain relief and rehabilitation of numerous injuries. The laser light penetrates tissue where it is absorbed by cells and effectively stimulates healing and rapid pain relief.

Micro-Current Electrical Stimulation stimulates the production of endorphins, which are the body’s natural pain relievers. As a result, local physiological changes become evident, namely muscle relaxation and improved circulation. When this occurs, oxygen flows more freely and promotes natural healing.

The LaserTouchOne which combines the two therapies in one device was compared in a clinical study to a cold laser device and separately a micro-current electrical stimulation device. The LTO device was successful in reducing pain by at least 2 points in 93.1% of the Completer population (compared with 83.3% with the TENS device and 62.5% with the LLT device).
