Abstract

This study aimed to compare the effects of sit-to-stand training, or training to stand up from sitting positions at various seat heights, on the balance recovery among stroke patients. This study included 20 stroke patients who were randomly divided into two groups. Each group was trained for six weeks, three times a week from March to June 2019. Static balance and dynamic balance were measured, and the variations were analyzed using the paired t-test and the independent t-test. There were significant changes observed in both static and dynamic balance (p<.05) before and after training. However, no significant changes were seen in the static balance in the standing posture with eyes closed (p>.05). This study confirmed that there was a significant effect of training on the balance of stroke patients, especially when progressively lower seat heights were used during the training. This suggests new directions for treatment during rehabilitation for balance recovery of stroke patients. Further studies will need to apply this training to a larger number of subjects, and use various training methods such as randomization of seat height to enable the generalization of the results of this study and application in clinical practice.

본 연구는 다양한 좌석 높이에서 일어서기 훈련이 뇌졸중환자의 균형에 미치는 영향에 대해 알아보고자 연구를 실시하였다. 연구의 대상자는 뇌졸중환자 20명이며 무작위로 표준좌석 높이 그룹 10명과 낮아지는 좌석높이그룹 10명으로 분류하여 2019년 3월에서 6월까지 주 3회 6주간 훈련을 실시하였다. 정적균형과 동적균형을 측정하였으며 그룹 내 훈련 전·후의 변화를 검증을 위하여 대응표본 t-검정을 실시하고, 그룹 간 훈련 전·후 변화의 차이를 검증하기 위하여 독립표본 t-검정을 실시하였다. 연구 결과, 그룹 내 훈련 전·후의 변화는 정적균형 및 동적 균형 모두 유의한 변화를 보였으나(p<.05), 그룹 간 훈련 전·후 변화량의 차이는 눈 감은 상태의 선자세 정적균형만 유의한 차이를 보이지 않았다(p>.05). 본 연구의 훈련이 뇌졸중 환자의 균형에 유의한 효과가 있음을 확인하였으며 특히, 훈련 시 좌석의 높이를 점진적으로 낮추어 제공하는 것이 뇌졸중 환자의 균형회복을 위한 새로운 치료방법으로 임상에서 활용되어 재활의 다양한 방향성을 제시되었음으로 사료된다. 그리고 연구 결과의 일반화를 위해 추후 연구는 많은 대상자에게 훈련의 적용이 필요하며 좌석 높이의 무작위 조성과 같은 다양한 훈련방법에 관한 연구들이 필요할 것이다.
