在最近的10例上斜肌麻痹中，患眼抬高了8.2+-。同侧头部倾斜45度时3.8度(标准差)。一个计算机模型预测上升到只有4.1度，但通过包括其他旋转垂直肌肉的反应，可以很容易地达到8.2度，特别是上直肌的过度反应(SR)。在17个较老的病例中，倾斜高度平均上升到15度。模型表明，这些偏差一定是由于SR过度行动造成的。分析表明，SR过度反应是最近病例中眼球抬高迅速增加的主要原因，而在老年病例中则进一步增加。
In ten recent cases of superior oblique (SO) palsy the involved eye elevated by 8.2 .+-. 3.8 deg (standard deviation) on 45 deg ipsilateral head tilt. A computer model predicted a rise to only 4.1 deg but could easily achieve 8.2 deg by including reactions in the other cyclovertical muscles, notably on overaction of the superior rectus (SR). In 17 older cases the elevation on tilt rose to an average of 15 deg. The model shows that these deviations must be due to SR overaction. The analysis suggests that SR overaction is the main cause of the rapid increase in eye elevation in recent cases and further increases in older cases.
