Role of Genetic Polymorphism in Neuroplasticity Involved in Dysphagia Recovery
調査の概要
詳細な説明
Neurogenic dysphagia attributable to acquired brain lesions, such as after stroke and after traumatic brain injury, are one of leading causes of chronic disability world widely and it is expected to substantially increase over the next two decades. Among various sequalae, dysphagia can be observed in about 40% -60% of post-stroke patients and 20% -30% of them might suffer from recurrent aspiration pneumonia and may inhibit recovery and can even lead to death. Recovery after brain lesions can be explained by specific molecular events. It is proven that Genetic polymorphisms associated with impaired neural repair or plasticity might reduce recovery from stroke. Not only for the motor recovery, but genetic polymorphism is also crucial for the recovery of swallowing after stroke, however, only limited amount of studies are available. Therefore, it is urgent to determine whether the recovery of swallowing disorders after stroke is affected by the inherent polymorphism of the patient, whether the degree of recovery and brain plasticity associated with swallowing depend on the gene characteristics and polymorphism of the patient and whether recovery in swallowing parallel to the recovery observed in other functional areas (ie. hand recovery, truncal control recovery, ADL recovery).
Based on the results of this study, results will be expected to help provide genetically tailored diagnosis and prognostication according to the gene polymorphism of the patient. Optimized treatment of the patient is expected to contribute to prevention of respiratory complications and improve functional outcome related to swallowing after stroke.

|
Change in Functional Oral Intake Scale(FOIS)
時間枠：initial 4 weeks,3months after onset
|
Functional oral intake scale(FOIS) is categorical scale range from 1 indicating severe dysphagia and 7 indicating safe oral feeding.
Higher change in FOIS indicates improvement of patient's swallowing function.
|
initial 4 weeks,3months after onset

Change in Berg Balance Scale(BBS)
時間枠：initial 4 weeks, 3 months after onset
|
BBS is a scale that measure person's static and dynamic balance abilities, ranging from 0 to 56 where 56 indicated independence in gait and 0 means unable to gait.
Higher change in Berg Balance Scale means improved patient's mobility.
|
initial 4 weeks, 3 months after onset

|
Change in Medical Research Council(MRC) grade Disability level
時間枠：initial 4 weeks, 3 months after onset
|
The modified Rankin Scale (mRS) is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. It is categorical value with the the scale running from 0-6, running from perfect health without symptoms to death. |
initial 4 weeks, 3 months after onset

|
Change in K-MBI(Korean Modified Barthel Index)
時間枠：initial 4 weeks, 3 months after onset
|
The Barthel scale or Barthel ADL index is an ordinal scale used to measure performance in activities of daily living (ADL).
Each performance item is rated on this scale with a given number of points assigned to each level or ranking.
Higher scores indicates indolence in ADL activities.
|
initial 4 weeks, 3 months after onset
|
|
Change in FAC(Functional Ambulatory Category)
時間枠：initial 4 weeks, 3 months after onset
|
The Functional Ambulation Categories (FAC) is 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 a personal assistive device .
Higher scores indicate better performance.

Change in Fugyl Meyer score from baseline
時間枠：initial 4 weeks, 3 months after onset
|
The Fugl-Meyer Assessment for upper extremity (FMA-UE)is considered to assess the body function according to the International Classification of Functioning, Disability and Health (ICF) with a maximum score of 66 points)

Change in scores of Quality of Life Survey score (EQ5D(EuroQol-5 dimension)
時間枠：initial 4 weeks, 3months after onset
|
The QOLS is a reliable and valid instrument for measuring quality of life from the perspective of the patient The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.
Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems.
The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions.
This decision results in a 1-digit number that expresses the level selected for that dimension.
The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.
