낙상 노인군과 비낙상 노인군간의 임상적 균형평가에서의 차이

Abstract

[한글]

본 연구의 목적은 낙상 노인군과 비낙상 노인군간의 임상적 균형평가에서 차이가 있는지를 알아보는데 있다.

연구대상은 서울대학교 병원과 서울 남부 노인 종합복지관을 이용하는 65세이상 노인 중 낙상 노인 24명과 비낙상 노인 22명을 대상으로 하였으며, 연구기간은 1998년 9월 15일부터 1998년 10월 10일까지였다.

낙상군과 비낙상군을 대상으로 Tinetti 균형평가, Ink foot prints 방법을 이용한보행분석, 4 가지의 조건(시각과 고유수용성) 하에서 한발로 서기를 평가하였다.

자료 분석은 SAS를 이용하여 t-검정, Pearson상관관계를 사용하였다.

결과는 다음과 같다.

1. Tinetti 균형평가에서 낙상군이 비낙상군에 비하여 유의하게 낮은 균형지수를 보였다.

2. 보행특성에서 낙상군이 비낙상군에 비하여 적은 분속수, 짧은 보장, 넓은 보폭을 보여 유의한 차이가 있었으나, 발각도에서는 유의한 차이가 없었다.

3. 한발로 서기에서 낙상군이 비낙상군에 비하여 4 가지 조건(시각, 고유수용성) 모두에서 낮은 점수를 보였으나, 조건 2(경지면 위에서 눈 감고 서기)에서는 유의한 차이가 없었다.

4. Tinetti 균형지수와 보행특성 중 분속수, 보장, 보폭은 유의한 상관관계가 있었으나, 발각도에서는 유의한 상관관계가 없었다.

5. Tinetti 균형지수와 한발로 서기에서 조건 1(경지면 위에서 눈 뜨고 서기),조건 2(경지면 위에서 눈 감고 서기), 조건 3(연지면 위에서 눈 뜨고 서기)에서는 유의한 상관관계가 있었으나, 조건 4(연지면 위에서 눈 감고 서기)에서는 유의한 상관관계가 없었다.

이상의 결과로 미루어 볼 때 Tinetti 균형평가에서 낙상군이 낮은 균형능력을 보였고, 보행분석에서도 역시 낙상군이 나쁜 보행특성을 보였다. 또한 4 가지의조건(시각과 고유수용성) 하에서 시행된 한발로 서기 평가에서도 낙상군이 낮은 능력을 보였다. 그리고 Tinetti 균형평가와 보행특성, 시각, 고유수용성 감각간에는 상관관계가 있었다.

The purpose of this study was to discribe the differences and correlations in the

Tinetti balance test, gait patterns and timed one leg stance between the fallers

and the non-fallers among healthy elderly.

Total 46 subjects (24 fallers and 22 non-fallers) were recruited from the Seoul

National University Hospital and Seoul Senior Nam-bu Welfare Center during

September 15, 1998 to Octorber 10, 1998. All subjects were healthy elderly, aged

over 65 years old. All subjects were measured the Tinetti balance test, the gait

patterns using ink foot prints and the time done leg stance with 4 conditions(2

visual x 2 proprioception input).The data were analyzed by SAS program using

Student t-test and Pearson's corrrelation efficacy.

The results were as follows:

1. The fallers exhibited significantly lower balance scores than Henon-fallers in

the Tinetti balance test.

2. The fallers exhibited significantly lower cadence, shorter step length, and

wider step width than the non-fallers in gait patterns. However, there was no

significant difference in foot angle.

3. The follers exhibited significantly lower scores than the non-fallers in timed

one leg stance with all conditions(visual and proprioceptio ninput), except

condition 2(one leg stance on hard surface with eye-closed),

4. In all subjects, there were significant correlations between the Tinetti

balance scores, cadence, step length, and step width except foot angle.

5. There were significant correlations between the Tinetti balance scores, timed

one leg stance with condition 1(one leg stance with eye-opened on hard surface),

condition 2(one leg stance with eye-closed on hard surface), and condition 3(one

leg stance with eye-opened on soft surface), However, there was no significant

correlation observed in condition 4(one leg stance with eye-closed on soft

surface).

In conclusion, this study suggested that the Tinetti balance test, gait patterns,

and sensory input were useful tools to evaluate the differences between fallers and

non-fallers.
