OBJECTIVES: Non-invasive transcranial direct current stimulation (tDCS) over the motor cortex is broadly investigated to modulate functional outcomes such as motor function, sleep characteristics, or pain. The most common montages that use two large electrodes (25-35 cm2 ) placed over the area of motor cortex and contralateral supraorbital region (M1-SO montages) require precise measurements, usually using the 10-20 EEG system, which is cumbersome in clinics and not suitable for applications by patients at home...

OBJECTIVES: Implicit regulation of emotions involves medial-prefrontal cortex (mPFC) regions exerting regulatory control over limbic structures. Diminished regulation relates to aberrant mPFC functionality and psychopathology. Establishing means of modulating mPFC functionality could benefit research on emotion and its dysregulation. Here, we tested the capacity of transcranial direct current stimulation (tDCS) targeting mPFC to modulate subjective emotional states by facilitating implicit emotion regulation...

INTRODUCTION: Intraoperative neuromonitoring for spinal cord stimulation uses electromyography (EMG) responses to determine myotomal coverage as a marker for dermatomal coverage. These responses are utilized to determine the orientation of the electrode. Somatosensory evoked potential (SSEP) collision testing can also be used in which sensory signals are decreased and/or eliminated when stimulation is activated. METHODS: Fifteen patients were observed in the study...

INTRODUCTION: Chorea-acanthocytosis (ChAc) is an autosomal recessive hereditary disorder caused by the mutation of gene VPS13A. Deep brain stimulation of ChAc has made substantial progress in the recent decades. However, the reports were scattered across centers and performed by different neurosurgeons. Here, we report a case series consisting of six patients diagnosed with ChAc, receiving bilateral high-frequency stimulation of globus pallidus internus (GPi) in a single center. METHODS: We report six consecutive patients diagnosed with ChAc and present a review of the literature...

OBJECTIVES: In rodents, we reported that short pulse-width (PW) neuromodulation might provide more efficient therapy delivery than traditional 0.21 msec PW. Using fully implanted, commercialized systems in the sheep, the goal of this study was to characterize the relationship of electromyographic (EMG) responses of the external anal sphincter (EAS) to different PWs of sacral neuromodulation (SNM). MATERIALS AND METHODS: In seven sheep, InterStim® quadripolar tined leads were implanted adjacent to the S3 nerve root bilaterally to deliver SNM and two pairs of intramuscular leads were placed on either side of the EAS for EMG sensing...

OBJECTIVE: Different approaches in neuromodulation have been used to treat chronic low back pain in failed back surgery syndrome (FBSS) patients. We previously randomized 52 FBSS patients to be treated with spinal cord stimulation (SCS) and additional peripheral nerve field stimulation (PNFS) or SCS alone. At three months, we found a significant reduction of back pain in the PNFS-SCS group compared to the SCS group. In the subsequent open phase part of the study, all patients received optimal SCS and PNFS simultaneously...

OBJECTIVE: Pain is a prevalent and debilitating nonmotor symptom of Parkinson's disease (PD) that is often inadequately managed. Deep brain stimulation (DBS) has been shown to relieve pain in PD but an effective method of identifying which types of PD pain respond to DBS has not been established. We examine the effects of DBS on different types of PD pain using the King's Parkinson's disease pain scale (KPDPS), the only validated scale of PD pain. METHODS: We prospectively followed 18 PD patients undergoing subthalamic nucleus (STN) or Globus pallidus interna (GPi) DBS...

INTRODUCTION: The increasing use of high frequency paresthesia-free spinal cord stimulation has been associated with improved outcomes in the therapy of neuropathic pain. What is unknown is the effect of varying frequency on pain relief and the placebo effect. MATERIALS AND METHODS: This is a prospective, randomized, sham-controlled double blind crossover study. Subjects with predominantly axial low back pain undergoing spinal cord stimulation therapy for failed back surgery syndrome were randomized to sham, 1200 Hz, 3030 Hz, and 5882 Hz with a four-phase crossover design over 12 weeks...

OBJECTIVES: Spinal cord stimulation (SCS) is an accepted, cost-effective treatment option for a variety of chronic pain syndromes, including failed back surgery syndrome (FBSS). The application of SCS in the cervical spine, particularly for pain after cervical spine surgery, has been drawn into question in recent years by payers due to a purported lack of clinical evidence. To challenge this claim, we analyzed data from a prospective registry to support the use of SCS in the cervical spine for pain after spine surgery...

BACKGROUND: The extent to which short interval intracortical inhibition (SICI) responds to low-frequency repetitive transcranial magnetic stimulation (rTMS) remains inconclusive with reports of increased, decreased and unchanged response following modulation. The aim of this study was to systematically investigate if the variability of SICI following rTMS is explained by the interstimulus interval (ISI) and/or the conditioning stimulus intensity (CSI). METHODS: Two experiments with pretesting/posttesting and an rTMS session (1 Hz, 90% RMT, 900 pulses) were done...
