Treating intractable postamputation pain with wearable, non-invasive, non-thermal, pulsed shortwave (radiofrequency) therapy: a randomized, double-masked, sham-controlled, crossover pilot study

Abstract

Pulsed shortwave (radiofrequency) therapy (PSWT) is a non-invasive, non-pharmacologic analgesic used for over 7 decades.[1 2][1] The mechanism of action involves multiple factors and is only partially understood.[3][2] Over-the-counter, lightweight, battery-operated, single-use, wearable devices
