편마비환자의 촉각분별력에 능동 및 수동 탐색의 차이 = The Difference between Active and Passive Exploration on Texture Discrimination Ability in Hemiplegic Patients

다국어 초록 (Multilingual Abstract)

Objective: The purpose of this study was to investigate the texture discrimination ability of correlated cognitive function by active and passive touch in hemiplegic patients. Methods: The subject were 15 hemiplegic patients with a mean age of 55.53. When subjects moved their fingers over the surfaces (active touch) and moved under the subject`s stationary finger (passive touch) displayed the same contact time as in the active touch experiments. Tactile task was used a set of five difference texture panel (10cm×10cm×0.5cm), and two conditions of three level (simple, complex, contrast). This approach was based on patterned, randomized texture panel applied to the fingertips for 30 seconds. The subjects ability to identify texture panel by means of active and passive haptic exploration was quantified by the cognitive exercise point to perform the tasks. Results: There was significant difference in sound side of active touch between low group and high group in the cognition. There was significant difference in simple task of active touch between 21 below group and 22 above group in the hand function. There was significant difference in discrimination task of both touch between 5 below group and 6 group in the Brunnstrom recovery stage. There were difference between sound side and affected side in the passive touch. There were also difference between active touch and passive touch in the affected side. Conclusion: The present study identify the haptic exploration method on changing cognitive exercise point in the hemiplegic patients. This results suggest that development training method on the recovery of hand function with hemiplegia. (J Korean Society of Neurocognitive Rehabilitation 2012;4:1∼9).

목적: 본 연구는 편마비 환자에서 능동탐색 및 수동탐색 시 촉각분별력의 차이를 알아보기 위함이다. 방법: 연구대상은 편마비환자 15명이었으며, 평균 연령은 55.53세 이었다. 패널위에서 손가락을 직접 움직이는 능동탐색과 치료사가 패널을 움직이는 수동탐색을 5개의 질감이 다른 패널을 사용하여 단순, 분별, 대조과제를 실시하였다. 결과: 인지수준, 손 기능수준, 브룬스트롬 회복단계에 따라 촉각분별력에 일부 차이가 있었다. 수동탐색시 건측이 더 촉각분별력이 높았으며, 환측의 능동탐색 시 더 촉각분별력이 높았다. 결론: 편마비환자의 촉각분별력은 탐색방법에 따라 차이가 있다. 편마비환자의 손 기능 회복 훈련을 조직화할 때 이러한 결과를 고려할 필요가 있다.
