I explored using EMS to slow progression of MS. The Playmakar sport device works great and I find it so helpful that I now get a recurring auto shipment of the electrode pads. Quality is top-notch. I usually spend 30 to 40 minutes daily stimulating different muscle groups. The manual that comes with the device is easy to understand with useful diagrams of pad placement. Very happy with this system and may purchase a back-up to be sure not to be without it.
