다국어 초록 (Multilingual Abstract)

Objective: Haptic perception involves both cutaneous perception, through mechanoreceptors lying on the skin, and kinaesthetic perception mediated by the position of the fingers. Softness perception has been shown to rely primarily on cutaneous cues. The purpose of this study was to investigate the correlation between the static two-point discrimination(TPD) and passive sponge softness discrimination(PSD) in people with normal. Methods: TPD and PSD testing were performed on 30 healthy adult, volunteers from first year occupational therapy class at the Yeoju Institute of technology. TPD and sponge compress force were measured using the aesthesiometer and the digital force gage. PSD was measured using the 3-different sponge per five size. To analyze the differences in sex, age groups independent t-test. Pearson`s correlation was used to assess the relationship between the TPD and PSD, and multiple linear regression analysis was also used to assess the regression coefficient with a significance level of .05 was used. Results: TPD were significant differences in the female compared with male of the scapular, hand, foot and PSD. TPD were significant differences in the below 20 age compared with over 20 age of the scapular and PSD. The showed that negative correlation between TPD and PSD with the scapular, hand, foot. As a result, Adjusted R square was 71.6%, the scapuar (beta-.699) and hand (beta-.300) was influenced. Conclusion: The above results suggest that the static two-point discrimination on the scapular and the hand was predicted value of the passive sponge softness discrimination in people with normal.

목적: 인지운동치료에서는 압각 차이를 인지하는 과제를 자주 사용한다. 본 연구의 목적은 건강인에게 이 점식별능력과 압각 차이 인지 능력 사이의 상관성을 알아보는 것이다. 방법: 본 연구의 대상자는 30명의 대학생으로 연령 범위는 19세부터 32세까지이며 평균 20.83세이었다. 남자는 9명이었으며 여자는 21명이었다. 검사 부위는 어깨뼈, 아래팔, 손등, 넙다리, 발등이었으며, 이점식별과 스펀지 압축력은 Aesthesiometer와 Digital force gage로 측정하였다. 압각 차이 인지 능력은 경도의 세 가지 조합(강-약, 강-중, 중-약)인 스펀지를 5개의 크기에서 각각 측정하였다. 자료의 분석은 독립표본 t검정 및 피어슨상관, 그리고 다중 회귀분석을 실시하였다. 결과: 성별에 따른 이점식별은 어깨뼈, 손등, 발등에서 여자가 유의하게 낮았으며, 압각 차이 인지 능력도 여자에서 유의하게 높았다. 20세 미만 군에서 어깨뼈의 이점식별 및 압각 차이 인지 능력이 유의하게 높았다. 압각 차이 인지와 이점식별의 상관성은 어깨뼈, 손등, 발등에서 유의한 음의 상관을 보였다. 또한 압각 차이 인지에 이점식별의 설명력은 71.6%이었으며, 어깨뼈가 가장 높았고 손등에서도 음방향의 유의한 영향을 보였다. 결론: 건강한 성인에서 이점식별 능력과 수동적 스펀지 압각 차이 인지 능력 간에 음의 상관성이 있음을 알 수 있었다. 위의 결과로 미루어보면, 어깨뼈와 손등에서의 이점식별 능력은 압각 차이 인지 능력에 대한 예측의 가치가 있다고 사료된다.
