초록

본 연구의 목적은 만성 뇌졸중 환자를 대상으로 균형 능력 검사인 버그 균형 척도(BBS), 앉고 일어서기 동작 검사(STS), 일어나 걸어가기 검사(TUG), 기능적 팔 뻗기 검사(FRT)와 보호균형 반응능력 검사인 최대보장검사(MSL)를 이용하여 낙상의 위험성을 예측하거나 낙상을 예측하는데 변별력이 있는지 알아보고자 하였다. 만성기 뇌졸중 환자 61명을 대상으로 뇌졸중 후 연구시점 까지 낙상 횟수를 기록하였다. 수용자 작업특성곡선(ROC curve)을 이용하여 측정 변수들의 낙상 예측 선별 기준값(cut-off value)을 구하였고 진단의 정확도를 알아보기 위하여 양ㆍ음성 예측도(PPVㆍNPV)를 구하였다. 측정 변수들간 연관성을 알아보기 위해 피어슨 상관계수를 나타내었고 변수들의 낙상 예측 선별 기준값은 낙상에 대한 위험정도를 알아보기 위하여 로지스틱 회귀분석을 통한 교차비를 구하였다. 연구 결과 STS의 선별 기준값은 15.88초(AUC=.77, 민감도=87%, 특이도=59%), TUG의 선별 기준값은 13.92초(AUC=.74, 민감도=80%, 특이도=72%), MSL의 선별 기준값은 32.57cm(AUC=.77, 민감도=80%, 특이도=65%), FRT의 선별 기준값은 17.97cm(AUC=.79, 민감도=93%, 특이도=67%), BBS의 선별 기준값은 24점(AUC=.70, 민감도=60%, 특이도=91%)으로 수용할 만 하였다. 로지스틱 회기분석에서 MSL, FRT는 낙상을 예측할 수 있는 변수인 것이 확인되었고 각각 32.57cm 이하, 17.97cm 이하에 해당하는 피검자들은 낙상을 경험할 확률이 각각 1.098배, 1.236배 증가하는 것으로 확인이 되어 만성 뇌졸중 환자들의 낙상을 예측하는데 효과적인 평가도구로 활용이 가능 할 것이다. 추후 연구에서는 보행 지구력과 보행 속도, 피검자의 신체조건(신장, 하지길이)을 고려하고, 최대보장 길이의 다방향 측정과 마비측에 따른 최대보장 검사 시 내딛는 다리의 기준을 제시하는 등 다양한 변인이 포함된 연구가 이루어져야 할 것이다.

Abstract

The purpose of this study was to evaluate the risk of falling or prediction validity for predictor of falls in patients with chronic stroke using the berg balance scale (BBS), sit to stand test (STS), timed up & go (TUG), functional reach test (FRT), and maximal step length (MSL). This study were included 61 patients with chronic stroke. 15 patients had once or no experience of falling, and 46 patients had experienced at least two falls. The receiver operation characteristic (ROC) curve was conducted to detect cut-off value of variables. The predictive value of measurement variables for accurately prediction of falls. The pearson's correlation coefficients were calculated to determine the strength of the relationships between variables and Odd ratio was calculated by logistic regression analysis in order to predict the degree of risk falls and non-falls. The selection standard value (AUC, sensitivity, specificity) for risk of falls of STS was 15.88s (.77, 87%, 59%), TUG was 13.92s (.74, 80%, 72%), MSL was 32.57cm (.77, 80%, 65%), FRT was 17.97cm (.79, 93%, 67%) and BBS was 24 score (.70, 60%, 91%) which were in the acceptable range. Adjusted bivariate logistic regression found MSL (p=.008) and FRT (p=.008) to be predictors for falls. The patients with chronic stroke who were MSL >32.57cm, FRT >17.97cm were 1.10 times, 1.29 times more likely to experience falls. We also recommended further study of considering walking endurance, walking speed, body condition(height, led length) of the subject and include a multidirectional measurement of the maximum step length and suggesting the leg criteria for the maximal step length on the consider paralyzed side.
