Multicenter Study Observational Study
Peripheral nerve field stimulation (PNFS) in chronic low back pain: a prospective multicenter study.
The goal of this study was to evaluate the long-term efficacy and safety of peripheral nerve field stimulation (PNFS) for chronic low back pain (cLBP). ⋯ This prospective, multicenter study confirms that PNFS is an effective therapy for the management of cLBP. Significant improvements in many aspects of the pain condition were measured, and complications were minimal.

Randomized Controlled Trial
Enhancement of affective processing induced by bifrontal transcranial direct current stimulation in patients with major depression.
Our aim was to evaluate whether one single section of transcranial direct current stimulation (tDCS), a neuromodulatory technique that noninvasively modifies cortical excitability, could induce acute changes in the negative attentional bias in patients with major depression. ⋯ Active but not sham tDCS significantly modified the negative attentional bias. These findings add evidence that a single tDCS session transiently induces potent changes in affective processing, which might be one of the mechanisms of tDCS underlying mood changes.

Clinical Trial
Safety and efficacy of vagus nerve stimulation paired with tones for the treatment of tinnitus: a case series.
Classical neuromodulation applies current to the nervous system in an attempt to alter ongoing activity. However, classical neuromodulation interferes with activity but does not drive it in a controlled way. Recently, an animal study demonstrated it is possible to drive plasticity in a controlled way by using stimulation of the vagus nerve paired with tones. This reversed the tinnitus percept and pathological neural plasticity in noise-exposed rats with behavioral characteristics of tinnitus. The aim of the current study was to translate this innovative neuromodulation method to humans suffering from tinnitus. ⋯ VNS paired with tones excluding the tinnitus-matched frequency is safe and feasible. It seems to exert a beneficial effect in nonmedication-taking patients, both with regard to the perceived sound and the distress. Further studies are therefore mandated.

This study aims to investigate the influence of deep brain stimulation (DBS) on caregiver burden and quality of life in Parkinson's disease. ⋯ Although there were several limitations to this study, DBS seems to improve quality of life without significantly increasing caregiver burden.
