Tests of motor function in patients suspected of having mild unilateral cerebral lesions

Jeanne S Teitelbaum¹, Michael Eliasziw, Michael Garner

片側の大脳半球の障害が疑われた際の身体所見はいくつかあるが、その診断精度は不明な点が多かった。

そこで、各種テストの精度を検討。

脳障害のある86名と脳障害の認められない84名で、各種テストを実施して、

感度・特異度・尤度比などを算出。

Table 1: Diagnoses of patient population

身体所見；

上肢バレー試験；日本で言われるバレー試験とは方法が異なる

Figure 1: Barré test (straight arm raising). The arms are held at a 90- degree angle with the body. Elbows are fully extended, wrists are dorsiflexed, and fingers are extended and abducted.

Pronator Drift；

Figure 2: Pronator drift. The arms are held at a 90- degree angle with the body. Elbows are fully extended, forearms are supine, wrists are straight, and fingers are extended and adducted.

Foream Roll；

Figure 3: Forearm roll. The patient is asked to rapidly roll each forearm around the other for 5 to 10 seconds in each direction.

ミンガッチーニ下肢試験；変法で腹臥位で行う下肢バレー徴候もある。

Figure 4: Mingazzini’s manoeuvre. The patient is lying on his back. The hips are flexed at a 75 to 80 degree angle, and the knees are held at a 100- degree angle that allows the leg to be horizontal to the bed. Ankles are dorsiflexed at 90 degrees. The position is held for as long as possible to a maximum of 30 seconds.
