Mortemus研究发现，癫痫猝死的患者通常处于俯卧位（也就是“趴着”）。芝加哥大学的JamesTao医师也发现（Neurology,)：70%的癫痫性猝死与俯卧体位有关。因此，避免癫痫大发作后的俯卧位对预防癫痫猝死非常重要。

然而，仅在睡觉的时候避免俯卧体位是不够的。最近浙大二院癫痫中心与芝加哥大学癫痫中心联合开展了一项研究，观察了癫痫监测病房中癫痫大发作前后患者的体位变化，发现1.6%的患者在扭转性运动中转变为俯卧位。

因此，对于出现癫痫大发作的患者，夜间的发作监测和看护，及时纠正体是非常重要的。如果患者独居，在癫痫大发作前存在扭转运动，他们使用癫痫发作的报警装备(录像监控或者癫痫报警手环）可能能够挽救生命。
