A:Answer I tried to wear it once above the knee and the main problem is slippage of the band. I think if I had their X-Large band, it would stay in place better. I wear leg braces due to wasted calf muscles, so for me personally, the calf, or a little lower works fine and is also accommodated by the shape of my braces. My body has compensated from having no useful calf muscle by my quads becoming really large and strong. Since they are doing the work of my entire lower leg, I think the constant movement of the muscle also contributes to the slippage.
I will say, calibrating every time I put it on helps based on how my pain is that day. It also allows me to not have to use the app to increase intensity as often. I will just calibrate beyond feeling a "slight tingle" as the app suggests, to feeling a stronger sensation. I think the I hope the system has worked to help with your pain.
