Transcranial direct current stimulation for spasticity in patients with multiple sclerosis: Exploring novel routes.

Patients with Multiple sclerosis (MS) usually suffer from severe neurological disabilities. Spasticity is one of the most bothering and disabling manifestations that MS patients suffer from. Owing to ... 5 consecutive daily sessions of 20 minutes duration of active anodal tDCS over the ipsilesional motor cortex were given to 10 relapsing remitting MS (RRMS) patients with at least 1 spastic lower limb ... Patients who received active anodal tDCS showed significant improvement (p< 0.05) in the H/M amplitude ratio as compared to the sham group. However, there was no significant difference between the two... Anodal direct current stimulation of the ipsilesional motor cortex in patients with MS, resulted in reduced spasticity as per neurophysiological assessment....

Comparing amplitudes of transcranial direct current stimulation (tDCS) to the sensorimotor cortex during swallowing.

Transcranial direct current stimulation (tDCS) can alter cortical excitability, making it a useful tool for promoting neuroplasticity in dysphagia rehabilitation. Clinical trials show functional impro... As a novel paradigm, tDCS, functional near-infrared spectroscopy (fNIRS), and surface electromyography (sEMG) were simultaneously administered while participants completed a swallowing task. This allo... There was no significant difference in the hemodynamic response by time or amplitude. However, post-hoc analyses indicated that in the post-stimulation period, changes to the hemodynamic response in t... During a swallowing task, healthy volunteers receiving 1 mA of anodal tDCS demonstrated a suppressed hemodynamic response during and after stimulation whereas those receiving 2 mA of anodal tDCS had a...

Anodal transcranial direct current stimulation enhances response inhibition and attention allocation in fencers.

The aim of this study is to investigate the acute effects of anodal transcranial direct current stimulation (tDCS) on reaction time, response inhibition and attention in fencers.... Sixteen professional female fencers were recruited, and subjected to anodal tDCS and sham stimulation in the primary motor area (M1) one week apart in a randomized, crossover, single-blind design. A t... The study found a significant improvement in response inhibition and attention allocation from pre-stimulation to post-stimulation following anodal tDCS but not after sham stimulation. There was no st... A single session of anodal tDCS could improve response inhibition, attention allocation in female fencers. This shows that tDCS has potential to improve aspects of an athlete's cognitive performance, ...

Differing effectiveness of transcranial random noise stimulation and transcranial direct current stimulation for enhancing working memory in healthy individuals: a randomized controlled trial.

Transcranial direct current stimulation (tDCS) applied to the left dorsolateral prefrontal cortex (DLPFC) is a promising technique for enhancing working memory (WM) performance in healthy and psychiat... This randomized, double-blind, sham-controlled trial enrolled 120 healthy right-handed adults who were randomly allocated to four stimulation groups: tRNS + direct current (DC) offset, tRNS, tDCS, or ... For the d-prime score during stimulation, the tRNS group significantly performed better than the sham group at online assessment (β = 0.310, p = 0.001). In the relationships between the benefit of eac... tRNS applied to the left DLPFC significantly improved WM performance and generated greater benefits for healthy individuals with lower WM performance. These findings highlight the potential utility of...
