Descrição detalhada

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.

O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Change in Functional Oral Intake Scale(FOIS)
Prazo: 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

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Change in Berg Balance Scale(BBS)
Prazo: 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
Prazo: 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)
Prazo: 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)
Prazo: 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.
initial 4 weeks, 3 months after onset
Change in Fugyl Meyer score from baseline
Prazo: 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)
initial 4 weeks, 3 months after onset
Change in MMSE-K(Korean Minimental Status Examination)
Prazo: initial 4 weeks,3months after onset
3. The Mini-Mental State Examination (MMSE) is a 30-point questionnaire that is used extensively to measure cognitive impairment.[1] Higher score indicates better cognitive function.
initial 4 weeks,3months after onset
Change in scores of Quality of Life Survey score (EQ5D(EuroQol-5 dimension)
Prazo: 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.
initial 4 weeks, 3months after onset
Change in Penetration-Aspiration Scale(PAS)
Prazo: 4 weeks, 3 months after onset
initial PAS is a categorical scale that measures level of penetration of bolus(food) into airway at pharynx. It ranges from Score 1 to 8, where 1 indicated no airway entrance of bolus and 8 indicated glottic passage of food. Higher change in PAS indicates improvement in patient's swallowing function.
4 weeks, 3 months after onset
Change in dysphagia outcome rating scale
Prazo: 4 weeks, 3 months after onset
initial The Dysphagia Outcome and Severity Scale (DOSS) is a simple, easy-to-use, 7-point scale developed to systematically rate the functional severity of dysphagia based on objective assessment and make recommendations for diet level, independence level, and type of nutrition with level 1 indicating severe dysphagia and level 7 indicating normal swallowing function.
4 weeks, 3 months after onset
Change in SWAL-QOL(swallowing quality of life)) survey score
Prazo: 4 weeks, 3 months after onset
initial SWAL-QOL is a survey that evaluation patient's subjective quality of life within their swallowing function. Scored will be sumed up where higher score indicates better quality of life.
4 weeks, 3 months after onset
Number of events associated with aspiration pneumonia
Prazo: 4 weeks, 3 months after onset
initial Diagnosis of aspiration pneumonia will be based on ≥3 of the following features: fever (>38°C), productive cough, abnormal respiratory examination, abnormal chest radiograph; specifically involving the dependent portions of the lung; white blood cell count >12,000/mL, or isolation of a relevant pathogen and use of antibiotics)
