Randomized Controlled Trial
Burst Transspinal Magnetic Stimulation Alleviates Nociceptive Pain in Parkinson Disease-A Pilot Phase II Double-Blind, Randomized Study.
Nociception is the most prevalent pain mechanism in Parkinson disease (PD). It negatively affects quality of life, and there is currently no evidence-based treatment for its control. Burst spinal cord stimulation has been used to control neuropathic pain and recently has been shown to relieve pain of nociceptive origin. In this study, we hypothesize that burst transspinal magnetic stimulation (bTsMS) reduces nociceptive pain in PD. ⋯ The Clinicaltrials.gov registration number for the study is NCT04546529.

High-Definition Transcranial Infraslow Pink-Noise Stimulation Can Influence Functional and Effective Cortical Connectivity in Individuals With Chronic Low Back Pain: A Pilot Randomized Placebo-Controlled Study.
Pain can be regarded as an emergent property of multiple interacting, dynamically changing brain networks and thus needs a targeted treatment approach. A novel high-definition transcranial infraslow pink-noise stimulation (HD-tIPNS) technique was developed to modulate the key hubs of the three main nociceptive pathways simultaneously, ie, the pregenual anterior cingulate cortex (pgACC) (descending inhibitory pathway), the dorsal anterior cingulate cortex (dACC) (medial nociceptive pathway), and both somatosensory cortices (S1) (lateral nociceptive pathway). This study aimed to evaluate safety and verify whether a single session of HD-tIPNS may disrupt functional and effective connectivity between targeted cortical regions. ⋯ The Clinicaltrials.gov registration number for the study is ACTRN12621001438842.

Randomized Controlled Trial
Effects of Anodal Transcranial Direct Current Stimulation on the Primary Motor Cortex in Women With Fibromyalgia: A Randomized, Triple-Blind Clinical Trial.
The aim of this study was to analyze the effects of ten sessions of active transcranial direct current stimulation transcranial direct current stimulation (tDCS) (2 mA) with 13:20:13 stimulation at M1 in women with fibromyalgia (FM). To the best of our knowledge, this is the first article that uses this protocol in patients with FM. The main hypothesis is that the protocol would be effective in decreasing pain and that the results would last for up to 90 days. ⋯ The results of this study suggest that active tDCS with an intensity of 2 mA for ten sessions was effective in decreasing pain and fatigue and improving QoL in patients with FM.

Effects of Prefrontal Transcranial Direct Current Stimulation on Retention of Performance Gains on an Obstacle Negotiation Task in Older Adults.
Complex walking in older adults can be improved with task practice and might be further enhanced by pairing transcranial direct current stimulation (tDCS) to the dorsolateral prefrontal cortex. We tested the hypothesis that a single session of practice of a complex obstacle negotiation task paired with active tDCS in older adults would produce greater within-session improvements in walking performance and retention of gains, compared to sham tDCS and no tDCS conditions. ⋯ The Clinicaltrials.gov registration number for the study is NCT03122236.

Effects of Multisession Transcranial Direct Current Stimulation on Stress Regulation and Emotional Working Memory: A Randomized Controlled Trial in Healthy Military Personnel.
Top-down stress regulation, important for military operational performance and mental health, involves emotional working memory and the dorsolateral prefrontal cortex (DLPFC). Multisession transcranial direct current stimulation (tDCS) applied over the DLPFC during working memory training has been shown to improve working memory performance. This study tested the hypothesis that combined tDCS with working memory training also improves top-down stress regulation. However, tDCS response differs between individuals. Resting-state electrophysiological brain activity was post hoc explored as a possible predictor of tDCS response. The predictive value of the ratio between slow-wave theta oscillations and fast-wave beta oscillations (theta/beta ratio) was examined, together with the previously identified tDCS response predictors age, education, and baseline working memory performance. ⋯ This study was preregistered on September 16, 2019, at the Netherlands Trial Register (www.trialregister.nl) with ID: NL8028.
