Intermittent Fasting Following Acute Ischemic Stroke

Study Overview
=================
Brief Summary
-----------------
Despite numerous kinds of evidence on functional health and CNS protection of intermittent fasting after injuries were found in many brain-, and spinal cord-damaged animal models, there has yet to be any clinical study of intermittent fasting after acute ischemic cerebral infarction. The aim of this study is to evaluate the neurological, functional and clinical efficacy of intermittent fasting in patients after acute ischemic stroke.

Detailed Description
-----------------
In order to verify the validity and clinical efficacy of intermittent fasting for neurological and functional effects of ischemic cerebral infarction, the first ischemic stroke (diagnosed within 1 year through brain MRI / CT) patients will be randomly assigned to intermittent fasting group or control group. In both groups, physical therapy, occupational therapy and speech therapy will be provided during 3 hours in total a day. The intermittent fasting group should maintain intermittent fasting for no less than 12 hours or more every day during the rehabilitation period (at least 1 week), and the control group is able to eat all of the hospital meals and all the participants want without any time limit. The efficacy of intermittent fasting is to be verified by performing the electro-physiological tests and functional evaluations before participation, 1st week, 2nd weeks after participation, before discharge, 3 months, and 6 months after the stroke onset.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of Surface electromyography | root mean square and root peak square of compound motor action potential | 1 day before the initiation of intervention, and 6 months after the stroke onset | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of Korean-modified Barthel index | Korean version-Modified Barthel Index (minimum of 0 and maximum scores of 100); higher values and a better outcome. | 1 day before the initiation of intervention and 3rd week after start of intervention, 3 months and 6 months after the stroke onset |
