Abstract

This study investigated the effectiveness of visual biofeedback simulation training for patients with incomplete spinal cord injuries. Fifteen people with an ASIA impairment scale of C and D, according to the intervention method, were studied. They were randomly divided into two groups, seven people in the experimental group and eight people in the control group. They were studied three times a week for six weeks using a Tetrax Interactive Balance System, for a total of eighteen times, and each test took fifteen minutes. Paired t-tests were used to evaluate the changes before and after intervention. The difference between the groups was compared using an independent t-test. The experimental group showed significantly increased general stability, fall risk index, weight distribution (A, C, D, LEFT, HEEL) and weight distribution index, except for synchronization AC, BD. However, the control group only showed significantly increased weight distribution (A, C, LEFT). In a variation, experimental and control groups showed significantly increased weight distribution (A, B, C, HEEL), general stability, fall risk index and synchronization AD. Consequently, it was found that visual biofeedback simulation training was effective for the balance ability of incomplete spinal cord injury patients, and further studies are required.

불완전 척수손상환자에게 시각적 바이오피드백 시뮬레이션훈련의 적용을 통해 균형에 미치는 영향을 알아보고자 하였다. 불완전 척수손상환자 중 기능향상을 기대할 수 있는 ASIA장애척도 C, D환자 15명을 실험군 7명, 대조군 8명으로 무작위 분류하였다. 균형진단과 바이오피드백 훈련이 가능한 Tetrax Interactive Balance System을 이용하여 시각적 바이오피드백 시뮬레이션훈련을 6주간 일주에 3회씩, 1회에 15분간 총 18회를 실시하였다. 분석방법은 집단 내 전과 후의 차이는 대응표본 t검정을 시행하였고, 두집단 사이 전후 변화량의 차이는 독립표본 t검정을 사용하였다. 실험군은 자세 흔들림을 측정하는 안정성지수와 낙상의 위험정도를 나타내는 낙상지수 및 각각의 체중 변화를 감지하는 체중분포도(A, C, D, LEFT, HEEL)와 체중분포지수에서 유의하게 향상되었고, 자세조절능력을 나타내는 동조화에서는 좌우뒤꿈치(AC)간과 좌우앞꿈치(BD)간을 제외하고 모두 유의하게 향상되었다(p<.05). 대조군은 체중분포도(A, C, LEFT)에서만 유의하게 향상되었다(p<.05). 실험군과 대조군간의 변화량에서 체중분포도(A, B, C, HEEL)와 안정성지수 및 낙상지수, 그리고 동조화 AD에서만 유의한 향상을 보였다(p<.05). 이 연구의 결과로 볼 때 불완전 척수손상환자에게 부가적으로 균형증진을 위한 시각적 바이오피드백 시뮬레이션훈련은 균형능력향상에 있어서 유용할 것이며 추후 더 많은 연구들이 시행되어야 할 것이다.
