Transcutaneous electrical nerve stimulation (TENS) is a minimally invasive method for treating pain. In the most recent review published in 2012, TENS was associated with increased pain relief following cardiothoracic surgery when compared to standard multimodal analgesia. The purpose of this systematic review and meta-analysis is to determine if adding TENS to current pain management practices decreases pain and analgesic use and improves pulmonary function for postcardiothoracic surgery patients. ⋯ The addition of TENS therapy to multimodal analgesia significantly decreases pain following cardiothoracic surgery, increases the recovery of pulmonary function, and decreases the use of analgesics.

How spinal cord stimulation (SCS) in its different modes suppresses pain is poorly understood. Mechanisms of action may reside locally in the spinal cord, but also involve a larger network including subcortical and cortical brain structures. Tonic, burst, and high-frequency modes of SCS can, in principle, entrain distinct temporal activity patterns in this network, but finally have to yield specific effects on pain suppression. Here, we employ high-density electroencephalography (EEG) and recently developed spatial filtering techniques to reduce SCS artifacts and to enhance EEG signals specifically related to neuromodulation by SCS. ⋯ EEG spectral analysis combined with spatial filtering allows for a spatially and temporally specific assessment of SCS-related, neuromodulatory EEG activity, and may help to disentangle therapeutic and side effects of SCS.

Randomized Controlled Trial Multicenter Study
A Prospective, Multicenter Study to Assess the Safety and Efficacy of Translingual Neurostimulation Plus Physical Therapy for the Treatment of a Chronic Balance Deficit Due to Mild-to-Moderate Traumatic Brain Injury.
Translingual neurostimulation (TLNS) studies indicate improved outcomes in neurodegenerative disease or spinal cord injury patients. This study was designed to assess the safety and efficacy of TLNS plus targeted physical therapy (PT) in people with a chronic balance deficit after mild-to-moderate traumatic brain injury (mmTBI). ⋯ Significant improvements in balance and gait, in addition to headaches, sleep quality, and fall frequency, were observed with TLNS plus targeted PT; in participants who had a chronic balance deficit following an mmTBI and had plateaued on prior conventional physiotherapy.

Multicenter Study
Factors Associated With Implantable Pulse Generator Site Pain: A Multicenter Cross-Sectional Study.
Implantable pulse generator (IPG) site pain following neuromodulation procedures is a recognized complication. The site of the IPG placement varies depending on the neuromodulation type and physician preference. The incidence of IPG site pain as a function of the site of IPG implantation has not been studied systematically. ⋯ The incidence of IPG site pain is an important complication of invasive neuromodulation. The anatomic location of the IPG placement does not appear to affect the incidence or severity of IPG site pain. However, the presence of a pre-implant chronic pain disorder does appear to affect the frequency and severity of IPG site pain.

Examining the Need to Standardize Implanted Stimulator Connectors: NANS Survey Results.
Connectors between implanted stimulator electrodes and pulse generators allow revisions, including battery changes or generator upgrades, to proceed without disturbing uninvolved components, such as the electrode. As new devices are introduced, however, connector incompatibility, even with updated hardware from the same manufacturer, can lead to additional procedures, expense, and morbidity. ⋯ Those who responded to our survey support the development of standard connectors for implanted stimulators, with voluntary compliance by manufacturers, to mitigate the need for adapters and facilitate interchanging components when appropriate. Other advantages to patients and manufacturers might accrue from the adoption of standards, as technology evolves and diversifies.
