The aim of this study was to evaluate the effectiveness and safety of a novel subperception spinal cord stimulation (SCS) waveform paradigm designed to target the dorsal horn dendrites for treating chronic neuropathic low back pain (LBP). The final 12-month results are reported here. ⋯ The Clinicaltrials.gov registration number for the study is ACTRN12618000647235 (anzctr.org.au).

The neuromodulatory effects of transcranial alternating current stimulation (tACS) on electroencephalogram (EEG) dynamics are quite heterogenous. The primary objective of the study is to comprehensively characterize the effects of two tACS protocols on resting-state EEG. ⋯ Characterizing the effects of multiple tACS protocols is critical to effectively target specific neural oscillatory patterns and to personalize the protocols. The study can be extended to target specific oscillatory patterns associated with cognitive deficits in neuro-psychiatric conditions.

Disorders of consciousness (DoC) represent a range of clinical states, affect hundreds of thousands of people in the United States, and have relatively poor outcomes. With few effective pharmacotherapies, neuromodulation has been investigated as an alternative for treating DoC. To summarize the available evidence, a systematic review of studies using various forms of neuromodulation to treat DoC was conducted. ⋯ While clinical outcomes were mixed and possibly confounded by natural recovery or pharmacologic interventions, deep brain stimulation appeared to facilitate greater improvements in DoC than other modalities. However, repetitive transcranial magnetic stimulation also demonstrated clinical potential with much lower invasiveness.

This study aimed to characterize the pelvic floor muscles (PFM) motor response provoked during sacral neuromodulation (SNM) lead placement, determining its utility in improving therapy delivery. ⋯ Intraoperative PFM electromyography obtained during lead placement aids in more accurate targeting of the lead to the nerve. To our knowledge, this is the first study to correlate tined lead placement based on electrodiagnostic testing and outcome in SNM. It has been proved to be a reliable measurement tool, serving as a physiological biomarker of treatment response during the test phase. A strong motor response can make the surgeon confident that the correct position of the lead has been established for maximal benefit.

Clinical interest in and utilization of peripheral nerve stimulation (PNS) for treating chronic pain has significantly increased in recent years owing to its potential for providing analgesia and improved function and quality of life in comparison with pharmacologic treatments. However, the relative infancy of PNS-specific systems and limited clinical practice guidance likely contribute to significant variation in PNS utilization patterns. ⋯ There is significant practice variation regarding the utilization of PNS across numerous key clinical considerations. Future research that explores the reasons driving these differences might help optimize patient selection, target selection, periprocedural management, and ultimately outcomes.
