Treatment of chronic pain with an auricular acupuncture device (P-Stim) in Singapore.

The P-Stim (Biegler GmbH, Mauerbach, Austria) is a portable auricular electroacupuncture stimulation device used for the treatment of pain. Compared to conventional acupuncture, it has the advantage of continuous auricular stimulation for up to 4 days. Its tolerability and efficacy has been demonstrated in studies involving European patients with chronic pain. 2 However, no data exists regarding its use in patients living in the tropics, where the weather tends to be hot and humid year-round. These are factors that may affect the wearability of P-Stim, especially if it’s to be worn over a prolonged period of time. Here we report the use of PStim in a series of subjects with chronic pain in a tropical country like Singapore.
