Background: Transcutaneous electrical sensory nerve stimulation (TESS) is used to enhance the recovery of sensorimotor function in post-stroke hemiparesis. However, TESS efficacy for post-stroke gait disturbance remains unknown. We hypothesized that TESS on the area innervated by the tibial nerve, targeting the superficial plantar sensation, combined with gait training would improve gait function in patients with gait disturbance caused by severe superficial sensory disturbance after stroke.

Objective: Developing new therapies to improve motor function in patients with severe chronic stroke remains a major focus of neurorehabilitation. In this prospective, non-controlled, pilot study, we aimed to investigate the effects of low-frequency repetitive transcranial magnetic stimulation (rTMS) combined with occupational therapy (OT) on the motor function recovery of the affected upper limb in chronic stroke patients with severe upper limb hemiparesis.

Methods: Consecutive patients (n = 40) diagnosed with chronic stroke (time since stroke, ≥1 year) and upper limb hemiparesis were enrolled in this study.

Background: A small lateral medullary lesion could produce isolated impairment of temperature sensation without concomitant impaired pain sensation. However, only one such case has ever been reported, and there are no reports on subjective symptoms and detailed somatosensory testing.

Case Presentation: Herein, we report the case of a 53-year-old female patient presenting with impaired temperature sensation on the left half of her body, from the neck down, following a small infarction of the right midlateral medulla.

Transcranial static magnetic stimulation (tSMS) is a novel non-invasive brain stimulation technique that reduces cortical excitability at the stimulation site. We investigated the effects of tSMS over the left primary motor cortex (M1) for 20 min on the local electroencephalogram (EEG) power spectrum and interregional EEG coupling. Twelve right-handed healthy subjects participated in this crossover, double-blind, sham-controlled study.

Transcranial static magnetic stimulation (tSMS) has been focused as a new non-invasive brain stimulation, which can suppress the human cortical excitability just below the magnet. However, the non-regional effects of tSMS via brain network have been rarely studied so far. We investigated whether tSMS over the left primary motor cortex (M1) can facilitate the right M1 in healthy subjects, based on the hypothesis that the functional suppression of M1 can cause the paradoxical functional facilitation of the contralateral M1 via the reduction of interhemispheric inhibition (IHI) between the bilateral M1.

Transcranial static magnetic stimulation (tSMS) is a new technique of non-invasive brain stimulation using a small, high-powered neodymium magnet placed on the scalp. It can reduce cortical excitability below the magnet. The aim of this study was to investigate the effect of tSMS on the intracortical excitability of the primary motor cortex (M1) contralateral to the M1 where the magnet was placed.
