Non-Invasive Pulsed Radiofrequency for the Treatment of Neuropathic Pain
Stanford University
Summary
The purpose of this study is to examine non-invasive pulsed radiofrequency (NIPRF) and the effect it has on chronic neuropathic pain. Chronic neuropathic pain after peripheral nerve injury most often occurs in the context of post-traumatic or post-surgical pain. It is often treated with nerve blocks, prescription medication, physical therapy, neuromodulation, and surgery. The study team will be examining the efficacy of NIPRF and determining if it would be an appropriate treatment for chronic neuropathic pain after peripheral nerve injury.The Stimpod used in the present study is FDA approved and will be used for on label purposes.
Eligibility

- Healthy volunteers
- No
Inclusion Criteria: * -Adults aged 18 or older with clinically diagnosed chronic neuropathic pain after peripheral injury defined as persistent or recurrent neuropathic pain caused by a peripheral nerve lesion, history of a plausible nerve trauma, pain onset in temporal relation to the trauma, and pain distribution within the innervation territory of a peripheral nerve (or nerves). Negative and positive sensory symptoms or signs must be compatible with the innervation territory of the affected nerve. Can be posttraumatic, post-surgical, nerve compression, nerve ischemia with or without loss o…
Interventions
- DeviceActive Treatment
The treatment is a non-invasive pulsed radio frequency current that emits a high frequency magnetic field. It has a pulse width of 0.2ms, a pulse rate of 2Hz and an intensity between 0 - 30ma. There is a 'beep' sound as the pulses occur. There are 2 electrodes used - one is the indifferent electrode that is placed on the skin at a suitable distance away from the active electrode and the other, an active electrode - is a probe that is applied to the target nerve to treat the mononeuropathy
- DeviceNon-active Treatment
The placebo device will be inert with nil current emitted however the device will look and be used in exactly the same way. There will also be a 'beep' sound emitted and only the investigator will know the difference. The placebo device will not deliver any electrical stimulation.
