Quell is designed to be worn on the upper calf, 1-2 inches below the knee so that it can stimulate the cluster of sensory nerves located there. If for whatever reason you cannot wear Quell below your knee, Quell can also be worn just above the knee (on the lower thigh) or at mid-calf. You should calibrate the device at the new site before initiating therapy. Please see Appendix D of the comprehensive User Manual.
