Analysis of Brain Diffusion Tensor Image in Stroke Patients

Study Overview
=================
Brief Summary
-----------------
This clinical study aims to confirm the characteristics of the functional ansiotropy value according to the individual characteristics of stroke patients by taking brain diffusion tensor images for stroke patients and using the MRI. To compare hematologic indicators and neurological function levels of stroke patients at the time of imaging examination with brain diffusion tensor imaging indicators.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Measurement of magnetic resonanace imaging (MRI) | MRI scan is a process of measuring changes of diffusion tensor tractography | Through study completion, an average of 1 day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Measurement of Korean version of coma recovery scale-revised (K-CRSR) | K-CRSR is Korean version of standardized neurobehavioral assessment measure designed for use in patients with disorders of consciousness. he scale is intended to be used to establish diagnosis, monitor behavioral recovery, predict outcome, and assess treatment effectiveness. | Through study completion, an average of 1 day | 
| Measurement of Korean version of Montreal Cognitive Assessment (K-MoCA) | K-MoCA is a measurement to evaluate the memory loss or other symptoms of cognitive decline. It contains 30 questions and taskes around to 12 minutes to complete. Scores range from 0 to 30. A score of 26 and higher is considered normal. | Through study completion, an average of 1 day | 
| Measurement of clinical dementia rate (CDR) | CDR is a rating scale for staging patients diagnosed with dementia. The CDR evaluates cognitive, behavioral and functional aspects of Alzheimer disease and other dementias. It is calculated on the basis of testing six different cognitive and behavioral domains such as memory, orientation, judgment and problem sloving, community affairs, home and hobbies performance, and personal care. The CDR is based on a scale of 0-3: no dementia (CDR = 0), questionable dementia (CDR = 0.5), MCI (CDR = 1), moderate cognitive impairment (CDR = 2) and severe cognitive impairment (CDR = 3) | Through study completion, an average of 1 day | 
| Measurement of Korean version of oxford cognitive screen (OCS-K) | OCS is an assessment of major cognitive domains of memory, language, number, praxis, executive functions and attention. | visit 1 | 
| Measurement of digit span test. | Digit span test is a measurment to assess the storage capacity of a person's working memory. A testperson is visually or auditorily to a sequence of digits on after another. Right afterwards, the test subject has to recall the correct digits in the same order. | Through study completion, an average of 1 day | 
| Measurement of digit span test. | inhibit cognitie interference. The stroop test consists of colors that are writen in words but in the wrong color ink, The test-taker has to be able to state the color that the word is written in and be able to ignore whatever the actual word is. | Through study completion, an average of 1 day | 
| Measurement of Korean version of western aphasia battery (K-WAB) | K-WAB is designed as an assessment tool to examine linguistic skills (information content, fluency, auditory comprehension, repetition, naming and word finding, reading, and writing) and main nonlinguistic skills (drawing, block design, calculation, and praxis) of adults with aphasia. | Through study completion, an average of 1 day | 
| Measurement of motricity index (MI) | MI is a process of the evaluating the function and strength of upper, lower extremities and trunk in score. | Through study completion, an average of 1 day | 
| Measurement of berg balance scale (BBS) | BBS is a measurement of balancing function. A five-point ordinal scale, ranging from 0-4. 0 indicates the lowest level of function and 4 the highest level of function. Total score = 56 | Through study completion, an average of 1 day | 
| Measurement of functional ambulatory category (FAC) | FAC is a measurement of a functional walking test that evaluates ambulation ability. This 6-point scale assesses ambulation status by determining how much human support the patient requires when walking, regardless of whether or not they use personal assistive device. | Through study completion, an average of 1 day | 
| Measurement of time up and go (TUG) | TUG is a measurement of a person's mobility and requires both static and dynamic balance. It uses the time that a person takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down. 11-20 seconds are within normal limits for frail elderly and disables patients, and greater than 20 seconds means the person needs assistance outside and indicates further examintaiton and intervention. A score of 30 seconds or more suggests that the person may be prone to falls. | Through study completion, an average of 1 day | 
| Measurement of Fugl-Meyer assessment (FMA) | FMA is a stroke-specific, performance-based impairment index. It is designed to assess motor functioning, balance, sesation and joint functioning in patients with post-stroke hemiplegia. It is applied clinically and in research determine disease severity, describe motor recovery, and to plan and assess treatment. | Through study completion, an average of 1 day | 
| Measurement of action research arm test (ARAT) | ARAT is a 19 item observational measurement to assess upper extremity performance (coordination, dexterity and functioning). Items comprising ARAT are categorized into four subscales (grasp, grip, pinch and gross movement). Task performance is rated on a 4-point scale, ranging from 0 (no movement) to 3 (movement performend normally) | Through study completion, an average of 1 day | 
| Measurement of Korean version of modified barthel index (K-MBI) | MBI is a measurement of degree of independence of a patient from any assistance. It covers 10 domains of daily activities: bowel and bladder control, grooming, toilet use, feeding, trasnfers, walking, dressing, climbing stairs and bathing | Through study completion, an average of 1 day | 
| Measurement of motion analysis | Motion analysis is a process of measuring and evaluating gait function in kinetic parameters of range of motion in angle of each joint by degree throguh Qualisys motion analysis system | Through study completion, an average of 1 day |
