Do Higher Transcranial Direct Current Stimulation Doses Lead to Greater Gains in Upper Limb Motor Function in Post-Stroke Patients?

Objective: To investigate whether a higher number of transcranial direct current stimulation (tDCS) sessions results in a greater improvement in upper limb function in chronic post-stroke patients. Materials and methods: A randomized, sham-controlled, double-blind clinical trial was conducted in 57 chronic post-stroke patients (≥ 3 months after their injuries). The patients were allocated to receive sessions of tDCS combined with physiotherapy and divided into three groups (anodal, cathodal, and sham).

The effect of tDCS on improving physical performance and attenuating effort perception during maximal dynamic exercise in non-athletes.

Objectives: This study aimed to test the effects of transcranial direct current stimulation (tDCS), using different electrode positioning and montages, on physical performance in maximum incremental tests of healthy non-athlete subjects.

Design: A double-blinded, crossover, sham-controlled study.

Method: Fifteen subjects (aged 25.

Intrahemispheric EEG: A New Perspective for Quantitative EEG Assessment in Poststroke Individuals.

The ratio between slower and faster frequencies of brain activity may change after stroke. However, few studies have used quantitative electroencephalography (qEEG) index of ratios between slower and faster frequencies such as the delta/alpha ratio (DAR) and the power ratio index (PRI; delta + theta/alpha + beta) for investigating the difference between the affected and unaffected hemisphere poststroke. Here, we proposed a new perspective for analyzing DAR and PRI within each hemisphere and investigated the motor impairment-related interhemispheric frequency oscillations.

Interhemispheric asymmetry of the motor cortex excitability in stroke: relationship with sensory-motor impairment and injury chronicity.

Objective: To compare the interhemispheric asymmetry of the motor cortex excitability of chronic stroke patients with healthy and to observe if the magnitude of this asymmetry is associated to sensory-motor impairment and stroke chronicity.

Methods: This cross-sectional study was performed with chronic stroke and aged and sex-matched healthy individuals. The interhemispheric asymmetry index was calculated by the difference of rest motor threshold (rMT) of the brain hemispheres.

Quantitative Electroencephalography Characteristics for Parkinson's Disease: A Systematic Review.

Background: Individualized treatment guided by biomarkers certainly will play a crucial role in the more effective treatment of various neurological diseases in the near future. Identifying the electroencephalographic biomarkers in the brain of patients with Parkinson's disease (PD) may help in the decision-making process of health professionals regarding the non-invasive brain stimulation (NIBS) protocols.

Objective: To summarize quantitative electroencephalographic (qEEG) characteristics of patients with PD with motor symptoms at rest or during movement to identify potential biomarker associated with motor impairment in PD.
