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.

Randomized Controlled Trial
Feasibility and Safety of High-Definition Infraslow Pink Noise Stimulation for Treating Chronic Tinnitus-A Randomized Placebo-Controlled Trial.
Tinnitus has been linked to activity and connectivity changes in the auditory cortex (AC), parahippocampus (PHC), and posterior cingulate cortex (PCC). Although previous studies have targeted these areas individually, no study has yet modulated them simultaneously. Furthermore, novel stimulation designs may be superior to traditional alternating or direct current stimulation. This pilot study investigated the feasibility and safety of a novel brain stimulation technique (high-definition transcranial infraslow pink noise stimulation [HD-tIPNS]) for treating chronic tinnitus targeting the AC, PHC, and PCC. ⋯ This study was registered with the Australia New Zealand Clinical Trial Registry (Registry number: ACTRN12621000151831; Universal Trial Number: U1111-1261-6945).

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.

The combination of repetitive transcranial magnetic stimulation (rTMS) and motor practice is based on the theory of neuromodulation and use-dependent plasticity. Predictive planning of occupational therapy (OT) is important for patients with rTMS conditioning. Recovery characteristics based on the severity of pretreatment upper extremity paralysis can guide the patient's practice plan for using the paretic hand. Therefore, we evaluated the recovery of patients with upper limb paralysis due to stroke who underwent a novel intervention of rTMS combined with OT (NEURO) according to the severity of upper limb paralysis based on the scores of the Fugl-Meyer assessment for upper extremity (FMA-UE) with recovery in proximal upper extremity, wrist, hand, and coordination. ⋯ This study had enough patients who were divided according to severity and stratified by lesion location and handedness parameters. Our results suggest that independently of these factors, the extent of recovery of upper limb motor parts after NEURO varies according to the severity of paralysis.
