There is a wealth of literature supporting the use of median nerve stimulation (MNS) for modulating autonomic nervous system (ANS) dysfunction such as in hypoxia, recovery after heart valve replacement, ischemia, and cardiac contractibility. Heart rate variability (HRV) is considered a gold standard for measuring autonomic modulation and dynamic nonlinear ANS processes through the use of an electrocardiogram (ECG). Although the use of MNS on HRV in animals and humans has been documented, optimal stimulation parameters are yet to be outlined. ⋯ Finding the optimal stimulation parameters for MNS is crucial for improving HRV. This will in turn contribute to normalizing ANS function impaired in numerous clinical conditions, such as epilepsy or diabetes.

Transcutaneous Tibial Nerve Stimulation in the Management of Overactive Bladder: A Scoping Review.
Overactive bladder (OAB) is a condition that has physical, social, psychosocial, and financial impacts. Transcutaneous tibial nerve stimulation (TTNS) is a modality that stimulates the nerve root fibers of L5-S3, the same spinal segments of the parasympathetic nervous system as the bladder. This scoping review aims to identify current literature available on the feasibility and outcomes of TTNS as a first-line treatment option for OAB. ⋯ TTNS is a promising first-line management option for people with OAB, particularly in the older population and for those with neurogenic bladder. It can provide symptomatic relief from urinary incontinence, frequency, urgency, and nocturia, while avoiding the bothersome side effects of more invasive or pharmaceutical therapies. Heterogeneity in treatment parameters limits generalizability and translation of the most appropriate clinical application and should be considered in future trials.

Randomized Controlled Trial
Higher Pain Sensitivity Predicts Efficacy of a Wearable Transcutaneous Electrical Nerve Stimulation Device for Persons With Fibromyalgia: A Randomized Double-Blind Sham-Controlled Trial.
This study investigated the efficacy of a transcutaneous electrical nerve stimulation (TENS) device (Quell®) for persons with symptoms due to fibromyalgia (FM). ⋯ This study found no differences between those who were exposed to maximal-frequency active stimulation or minimal-frequency sham stimulation from a wearable TENS in reducing FM-related symptoms. However, those with greater hypersensitivity showed most benefit from TENS. Additional studies to help determine the role individual differences play in the use of TENS in managing FM-related symptoms are needed.

To evaluate if electrodiagnostic tools can advance the understanding in the effect of sacral neuromodulation (SNM) on pelvic floor activity, more specifically if SNM induces changes in pelvic floor muscle (PFM) contraction. ⋯ This is the first study to describe in detail the neurophysiological characteristics of the PFM, and the changes over time upon sacral spinal root stimulation, in responders and nonresponders to SNM. More research is needed to investigate the full potential of EPFMR as a response indicator.

Randomized Controlled Trial Comparative Study
Comparison of Two Different Pulsed Radiofrequency Modes for Prevention of Postherpetic Neuralgia in Elderly Patients with Acute/Subacute Trigeminal Herpes Zoster.
Trigeminal postherpetic neuralgia (PHN) is often refractory to treatment. Pulsed radiofrequency (PRF) neuromodulation can help in preventing PHN after herpes zoster. This study aimed to compare the efficacy and safety of two different PRF modes on gasserian ganglion neuromodulation in elderly patients with acute/subacute trigeminal herpes zoster. ⋯ ChiCTR2000038775.
