Last OEM version of the Scrambler Therapy® Technology device. In production since 2021 (full made in Italy). To optimize product quality and comply in advance with the constantly evolving international requirements for Medical Devices, production was moved from Korea (previous generations MC-5A) to Italy. On this occasion the new device was improved in many parts such as mechanics, design, connectors, EMC, quality control. The power supply system now also accepts 110-120V. The new Scrambler Therapy® ST-5A device replace previous model MC-5A, and it is the only Scrambler Therapy® device on the market.

The scientific literature indexed and published in peer review scientific journals, based exclusively on this technology, shows several clinical studies on:
