The geko® device is only to be used on the lower limbs. Secure the device to the leg so that the location marker (the line of arrows) is positioned directly over the centre of the fibula head. Correctly fitted, the longer tail should wrap around to the rear of the leg, below and parallel to the crease of the knee. This will place the negative electrode over the common peroneal nerve and will position the ‘plus’ button at the front of the leg and the ‘minus’ button to the rear. The device can also be placed in two alternative fitting locations, just above and just below the crease of the knee aligned to the lateral outer tendon.
