Neuromuscular electrical stimulation has been widely used in patients with dysphagia. However, obtaining sufficient hyoid bone movement through surface electrodes seems difficult. The aim of this study was to evaluate hyoid bone movement at rest through peripheral magnetic stimulation of the suprahyoid muscles in normal individuals. ⋯ Peripheral magnetic stimulation is noninvasive and easy to perform. It does not require skin preparation, facilitates sufficient hyoid bone movement, and causes minimum level of pain.

Primary Sjögren's syndrome (pSS) sufferers have rated chronic fatigue as the most important symptom needing improvement. Emerging data suggest that stimulation of the vagus nerve can modulate immunological responses. The gammaCore device (electroCore), developed to stimulate the cervical vagus nerve noninvasively, was used to assess the effects of vagus nerve activation on immune responses and clinical symptoms of pSS. ⋯ The vagus nerve may play a role in the regulation of fatigue and immune responses in pSS and nVNS may reduce clinical symptoms of fatigue and sleepiness. However, a sham-controlled follow-up study with a larger sample size is required to confirm the findings.

Randomized Controlled Trial Multicenter Study Comparative Study
A Randomized Controlled Trial of Subcutaneous Nerve Stimulation for Back Pain Due to Failed Back Surgery Syndrome: The SubQStim Study.
To compare the effectiveness of peripheral nerve stimulation utilizing a subcutaneous lead implant technique-subcutaneous nerve stimulation (SQS) plus optimized medical management (SQS + OMM arm) vs. optimized medical management alone (OMM arm) in patients with back pain due to failed back surgery syndrome. ⋯ The results indicate that the addition of SQS to OMM is more effective than OMM alone in relieving low back pain at up to nine months.

Randomized Controlled Trial Comparative Study
High-Frequency (10 kHz) Electrical Stimulation of Peripheral Nerves for Treating Chronic Pain: A Double-Blind Trial of Presence vs Absence of Stimulation.
The study objectives were to perform a clinical audit of patients implanted with 10 kHz spinal cord (SCS) and peripheral nerve (PNS) stimulators for treating chronic pain and to investigate the effect of 10 kHz PNS on pain and other sensory modalities in a double-blind cross-over trial. ⋯ These findings suggest that PNS at 10 kHz decreases pain when conducted for at least four hours. Stimulation analgesia does not appear to be due to sensory conduction block.

Kilohertz high-frequency alternating current (KHFAC) electrical nerve stimulation produces a reversible nerve block in peripheral nerves in human patients with chronic pain pathologies. Although this stimulation methodology has been verified with nonselective extrafascicular electrodes, the effectiveness of producing a selective nerve block with more-selective intrafascicular electrodes has not been well documented. The objective of this study was to examine whether intrafascicular electrodes can block painful stimuli while preserving conduction of other neural activity within the implanted nerve. ⋯ KHFAC stimulation in peripheral nerves through intrafascicular electrodes demonstrated a selective reduction in pain sensitivity while preserving other nerve functions. This treatment may benefit patient populations who have chronic pain originating from peripheral nerves, but who do not want to block whole-nerve function in order to preserve sensory and motor function reliant on the implanted nerve. Furthermore, KHFAC may benefit patients who respond negatively to other forms of peripheral nerve stimulation therapy.
