  • Background: Recently, the kinesiology taping (KT) method was reported to be effective in improving walking ability in foot drop patients after stroke, but the clinical basis is still unclear. Objectives: The KT method was compared with ankle-foot orthotics (AFO) to investigate gait ability in foot drop patients after stroke. Design: Crossover study design. Methods: In this study, 11 stroke patients with foot drop participated. Walking ability of all subjects for both conditions (KT and AFO) was measured using the GAITRite system. The order of application of the two conditions was determined randomly by drawing lots. Wilcoxon signed-rank test was used to compare walking ability between the two conditions. The level of statistical significance was set at P<.05. Results: There were no significant differences between the KT and AFO methods in terms of velocity, cadence, step length, and stride length (P>.05, all). Conclusion: This study recommends KT as an alternative to the AFO, since KT provides evidence of preventing of foot drops and improving gait ability in stroke patient.

  • 목적: 최근 치과 영역에서 CAD-CAM (computer aided design-computer aided manufacturer) 시스템의 이용과 디자인 소프트웨어가 늘어남에 따라 쉽고 빠른 수복물의 디자인이 가능해졌다. 과거에는 치과 기공사의 wax up 기술의 숙련도에 따라 금관의 외형이 결정 되었으나, CAD-CAM 시스템에서는 디자인 소프트웨어에 대한 숙련도가 더 중요한 요인이 되어가고 있다. 이에 치과 기공사와 치과의사간의 결과물의 차이를 알아보고자 한다. 재료 및 방법: 대합치와 인접치가 양호한 환자의 하악 우측 제1대구치를 금관 지대치 형성 한 후 polyether로 인상채득 하였다. 인상재에 초경석고를 이용하여 모형을 제작 하였으며, Trios 구강내 스캐너를 이용하여 STL (stereolithography) 파일을 추출하였다. 3shape dental designer 상에서 5년 이상 경력의 치과 기공사 1명, 2년 이하 경력의 치과 기공사 3명, 4명의 보철과 1년차 전공의가 동일한 STL 파일을 이용하여 금관을 디자인 하였다. CAD-CAM 시스템 경력이 가장 오래된 기공사의 디자인을 기준으로 하여 치과 기공사 그룹 3명(group DT)과 1년차 전공의 그룹 4명(group RT) 의 금관 외형을 비교하였다. 디자인된 금관의 근원심폭, 협설폭, 높이, 교두간 거리, 대합치와의 접촉점의 수를 측정, 비교 하였다. 독립표본 t검정을 시행하여 그룹간의 차이를 비교하였고, 대합치와의 접촉점의 수는 Wilcoxon signed-rank test 를 이용하였다. 결과: 정규성 검정 결과 근원심폭, 협설폭, 높이, 교두간 거리는 정규분포를 보였다. Group DT와 group RT의 금관 디자인상에서 근원심폭, 협설폭, 높이, 교두간 거리에서 통계적으로 유의할만한 차이가 없었다. 대합치와의 접촉점 수는 정규분포를 보이지 않았으며, wilcoxon signed-rank test 결과 통계적으로 유의한 차이를 보이지 않았다. 결론: 금관의 외형의 크기에 있어서는 group DT와 group RT 사이에 통계학적으로 유의할만한 차이가 없었지만 수치화하기 어려운 금관의 해부학적 형태나 주변 치아와의 형태적 유사성 등은 차이가 있었다. 디자인 소프트웨어에 대한 숙련도가 높아진다면 각 술자가 가지고 있는 교합에 대한 개념을 더 구현하기 쉬울 것이다.

  • This study was performed to determine the inter-rater reliability of manual tests of elbow, knee flexor, and ankle dorsiflexor muscle spasticity graded on the Modified Ashworth Scale. Two raters each independently graded the spasticity of 32 patients with intracranial lesions after moving the paretic limb passively through the available range of motion. The patients were asked to simultaneously squeeze therapeutic putty with their non-paretic hand for reinforcement. The ratings were compared by the Wilcoxon matched pairs signed-rank test and by the Kendall's coefficient of rank(tau) correlation. There was singificant correlation between two raters for spasticity at the elbow, knee flexor, and ankle dorsiflexor. The correlations of the two raters ranged from .6746 to .9308. The highest correlation was for the elbow with reinforcement and the lowest was for the knee without reinforcement. Poorer correlation was evident in the knee joint. The positive results of this study encourage the continued use of manual tests of muscle spasticity, using the Modified Ashworth Scale.

  • Purpose: In this study, the effects of an alcohol education program for elderly persons with drinking problems and the effects of knowledge of the behavior associated with alcohol use by elderly individuals with drinking problems were evaluated. Method: A single-group repeated study was conducted to evaluate 19 elderly individuals with drinking problems who used the G-city Elderly Welfare Center, with more than eight points in AUDIT results. The changes in drinking knowledge and alcohol behavior following an alcohol education program were evaluated. The effectiveness of the program was analyzed by a Wilcoxon signed rank test. and the relationship between drinking knowledge and changes in alcohol behavior was measured by Spearman's rank correlation coefficient. Results: The results indicated that drinking knowledge after conducting education increased significantly(Z=-3.826, p<.001), and that this increased knowledge resulted in significant changes in alcohol behavior(Z=-3.830, p<.001). There was a significantly positive relationship between drinking knowledge and changes in alcohol behavior(r=.464, p=0.013). Conclusion: Alcohol education programs effectively educate the elderly with drinking problems regarding alcohol, which influences their alcohol behavior.

  • The aim of this study was to determine the effect of action-observation training on arm function in people with stroke. Fourteen chronic stroke patients participated in action-observation training. Initially, they were asked to watch video that illustrated arm actions used in daily activities; this was followed by repetitive practice of the observed actions for 3 times a week for 3 weeks. Each training session lasted 30 min. All subject participated 12 training session on 9 consecutive training days. For the evaluation of the clinical status of standard functional scales, Wolf motor function test was carried out at before and after the training and at 2 weeks after the training. Friedman test and Wilcoxon signed rank test was used to analyze the results of the clinical test. There was a significant improvement in the upper arm functions after the 3-week action-observation training, as compared to that before training. The improvement was sustained even at two weeks after the training. This result suggest that action observation training has a positive additional impact on recovery of stroke-induced motor dysfunctions through the action observation-action execution matching system, which includes in the mirror neuron system.
