脳血管障害患者の手指感覚機能

Clinical assessment of sensory impairment in stroke patients

要旨：脳血管障害患者150例において，感覚障害テストの定量化に努めた上でそれを測定し，運動麻痺とともに評価した．そして，感覚障害の構造，運動麻痺との関係について検討した．

　1)度数分布の検討から，特に識別的感覚障害の二極化傾向が強いこと，2)感覚テスト間の難易度差が各種感覚障害間の相関に大きく関与すること，3)感覚障害と運動麻痺との間の相関は低いこと，が示唆された．また，識別的感覚テストの難易度が高いこと，異常感覚を生ずる場合が多いことが示された．感覚検査のさらなる定量化の問題とともに，異常感覚の影響に関する検討が課題として残った．

　In this study, we examined 150 stroke patients using a quantitative sensory disturbance test. The results were evaluated in relation to their motor disturbance. We investigated the structure of sensory disturbance and the relationship between sensory disturbance and motor disturbance.

　1) Judging from the distribution of frequency, there was a conspicuous tendency toward bipolarization in discrimination sensory disturbance.

　2) The difference in the degree of difficulty among sensory tests was mainly due to the relationships among various sensory disturbance.

　3) There was a negligible level of correlation between sensory disturbance and motor disturbance.

　On top of the above-mentioned, we also found out that the discrimination sensory test was highly difficult for the stroke patients, and that many cases of dysesthesia were observed among the stroke patient.

　We'll have to pursue further quantification of the sensory test; also, the influence of dysesthesia should be clarified in the future.
