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.

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.

Percutaneous Peripheral Nerve Stimulation (PNS) for the Treatment of Chronic Low Back Pain Provides Sustained Relief.
The objective of this study was to evaluate the use of percutaneous peripheral nerve stimulation (PNS) for the treatment of chronic low back pain (LBP). Percutaneous PNS offers the potential to provide an effective neuromodulation therapy using a system and fine-wire leads designed specifically for percutaneous use with history of an excellent safety profile. ⋯ This work demonstrates the potential value of percutaneous PNS for the treatment of chronic LBP. Improvements in pain, medication, and patient-centric outcomes, which were sustained long term after the removal of PNS leads, demonstrate the significance of this innovative approach to treat chronic LBP.

Randomized Controlled Trial
Needleless Transcutaneous Neuromodulation Accelerates Postoperative Recovery Mediated via Autonomic and Immuno-Cytokine Mechanisms in Patients With Cholecystolithiasis.
Postsurgical gastrointestinal disturbance is clinically characterized by the delayed passage of flatus and stool, delayed resumption of oral feeding, dyspepsia symptoms, and postsurgical pain. This study was designed 1) to evaluate the effects of needleless transcutaneous neuromodulation (TN) on postoperative recovery; 2) to investigate mechanisms of the TN involving autonomic functions in postoperative patients after removal of the gallbladder. ⋯ In conclusion, the proposed needleless TN accelerates postoperative recovery after LC, possibly mediated via the autonomic and immune-cytokine mechanisms. Needleless and self-administrable TN may be an easy-to-implement and low-cost complementary therapy for postoperative recovery.

The objective of the present feasibility study was to investigate the use of a new treatment modality-percutaneous peripheral nerve stimulation (PNS)-in controlling the often severe and long-lasting pain following total knee arthroplasty (TKA). ⋯ This feasibility study suggests that for TKA, ultrasound-guided percutaneous PNS is feasible in the immediate perioperative period and may provide analgesia without the undesirable systemic effects of opioids or quadriceps weakness induced by local anesthetics-based peripheral nerve blocks.
