A method of selectively blocking a portion of a nerve signal is disclosed. The method may include the step of providing an electrode around a subjects peripheral nerve and connecting the electrode to a stimulator. The stimulator may then energize the electrode with a continuous periodic waveform of at least 50 kHz. This energization of the electrode can result in the selective block of one of: 1) a fast portion of a nerve signal having a conduction velocity greater than 2 m/s, and 2) a slow portion of the nerve signal having a conduction velocity less than 2 m/s. A method according to the present disclosure may allow the non-blocked portion of the nerve signal to be conducted substantially unimpeded.
