Effects of Brain Network by Simultaneous Dual-mode Stimulation in Subacute Stroke Patients

2017-09-13 00:23:22 | BioPortfolio

Summary

Repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) has been used for the modulation of stroke patients' motor function by altering the cortical excitability. Recently, more challenging approaches, such as stimulation of two or more sites or use of dual modality have been studied in stroke patients. In this study, simultaneous stimulation using both rTMS and tDCS (dual-mode stimulation) over bilateral primary motor cortices (M1s) was investigated to compare its modulatory effects with single rTMS stimulation in subacute stroke patients.

Description

We assessed each patient's motor function using the Fugl-Meyer Assessment (FMA) score and acquired their resting-state fMRI (rs-fMRI) data at two times: prior to stimulation and 2 months after stimulation. Changes in rs-fMRI network measures were investigated between groups.

Medical and Biotech [MESH] Definitions

Restoration of functions to the maximum degree possible in a person or persons suffering from a stroke.

Stroke caused by lacunar infarction or other small vessel diseases of the brain. It features hemiparesis (see PARESIS), hemisensory, or hemisensory motor loss.

A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature. (From Adams et al., Principles of Neurology, 6th ed, pp777-810)

A condition caused by the failure of body to dissipate heat in an excessively hot environment or during PHYSICAL EXERTION in a hot environment. Contrast to HEAT EXHAUSTION, the body temperature in heat stroke patient is dangerously high with red, hot skin accompanied by DELUSIONS; CONVULSIONS; or COMA. It can be a life-threatening emergency and is most common in infants and the elderly.

A strain of Rattus norvegicus with elevated blood pressure used as a model for studying hypertension and stroke.
