A Spinal Functional Magnetic Resonance Imagine (fMRI) Study of Resting-State, Motor Task and Acupoint Stimulation
The spinal cord is a very important part of the central nervous system. fMRI can be applied to observe functional status of the human spinal cord. Under different conditions, the investigators will see different types of fMRI signals within the spinal cord. In resting state, the investigators might see active/inactive signals, too.

Infarction, Anterior Cerebral Artery
NECROSIS occurring in the ANTERIOR CEREBRAL ARTERY system, including branches such as Heubner's artery. These arteries supply blood to the medial and superior parts of the CEREBRAL HEMISPHERE, Infarction in the anterior cerebral artery usually results in sensory and motor impairment in the lower body.
Middle Cerebral Artery
The largest of the cerebral arteries. It trifurcates into temporal, frontal, and parietal branches supplying blood to most of the parenchyma of these lobes in the CEREBRAL CORTEX. These are the areas involved in motor, sensory, and speech activities.
The formation of an area of NECROSIS in the CEREBRUM caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction).
A mechanism of communicating one's own sensory system information about a task, movement, skill, etc.
Infarction, Middle Cerebral Artery
NECROSIS occurring in the MIDDLE CEREBRAL ARTERY distribution system which brings blood to the entire lateral aspects of each CEREBRAL HEMISPHERE. Clinical signs include impaired cognition; APHASIA; AGRAPHIA; weak and numbness in the face and arms, contralaterally or bilaterally depending on the infarction.
Cerebral Palsy (CP) is characterized by a sensory-motor deficiency, involving disturbance of muscle tone, posture and voluntary movement. Children who are afflicted need special intense ca...
The purpose of this study is to determine if using high-intensity, short-duration, intermittent neuromuscular electrical stimulation (NMES) is better than volitional exercise in increasing...
Deep Brain Stimulation represents the golden standard for surgical treatment of Parkinson disease (PD), but it is not optimally effective for controlling every motor sign and adverse event...
The objective is to determine if motor cortex stimulation works for the following conditions: 1. Deafferentation facial pain, 2. Upper extremity complex regional pain syndrome...
The problems in motor activity associated with Parkinson's disease are still poorly understood. Patients with Parkinson's disease often suffer from extremely slow movements (bradykinesia)...
Percutaneous spinal stimulation is a promising new technique for understanding human spinal reflexes and for evaluating the pathophysiology of motor roots. Previous studies have generally stimulated t...
The aim of this study was to determine how and whether changes in the primary motor cortex (M1) are affected by dual motor task. We further investigated how dual motor task is dependent on task proper...
This study aimed to elucidate electrophysiological and cortical mechanisms involved when 15 healthy right-handed subjects executed an index finger flexion and extension task before and after hand immo...
The purpose of this study was to examine the influence of subthreshold electrical stimulation on the force fluctuations and motor-unit discharge variability during low-level, steady contraction of the...
This study focused on the effects of electrical stimulation of cerebellar fastigial nucleus on the expression of growth arrest and DNA damage inducible gene β (Gadd45β) and on motor function recover...
