Randomized Controlled Trial
Outcome of a High-Frequency Transcutaneous Electrical Nerve Stimulator (hfTENS) Device for Low Back Pain: A Randomized Controlled Trial.
This controlled trial examined the benefit of a high-frequency transcutaneous electrical nerve stimulation (hfTENS) device (the Quell, NeuroMetrix, Inc., Waltham, MA, U.S.A.) for patients with chronic low back pain (CLBP). ⋯ These results suggest that hfTENS can have a moderate effect in reducing pain and improving quality of life in low back pain patients. Further trials designed to determine the mechanism of action of the hfTENS are needed.

In this study we aimed to identify specific factors predicting successful outcomes after percutaneous radiofrequency thermocoagulation (RFT) for idiopathic trigeminal neuralgia (ITN) and risk factors that were associated with inferior outcomes. ⋯ Presence of provoked episodic pain and mixed pain were significantly associated with successful outcome of RFT for ITN. Moreover, patients with ITN who underwent RFT for the first time were more likely to benefit from successful outcome. These findings should be considered when managing ITN with RFT to improve the likelihood of a successful outcome.
