- Abstract Applied as a bedside test of gross dorsal column function, the testing of light touch (LT) sensation is of high clinical value in the diagnosis of human spinal cord injury (SCI). However, the assessment of overall dorsal column deficit by testing only LT may be limited, because the dorsal c

- 体表面上の2点に機械的刺激をあたえたとき,視覚によらずにこれらが別々の刺激によるものであると識別できる最小の距離を二点弁別閾という。
- 二点弁別閾は部位によって大きな差があり,一般に指先や口唇などで小さく,上腕・下腿・背部などで大きい
- 二点弁別閾の大きさは,その刺激を感受する識別性触圧覚の受容器の密度や,大脳皮質感覚野の担当領域の広さによってきまると考えられている.
- 体表面での触点または圧点の密度は二点弁別閾の大きさに反比例し,指先や口唇で高く,上腕・下腿・背部などで低い.
- このため触圧覚の閾値は,指先や口唇などで低く,上腕・下腿・背部などで高い.
- 注) 部位によって大きな差があり: 背部での二点弁別閾は60~70mmであるの対し,指では3~5mm程度である.
- 注) 触圧覚の閾値: 触圧覚の閾値は,くわえられた刺激の力(g/mm2),皮膚の変位(μm),皮膚圧迫の速度(mm/s)などできまる.身体各部の感覚点の閾値は,小さな断面積の毛で調べられており,指先の閾値は腕や体幹での閾値の10~30倍である.
