腔室症候群的典型指標是極度疼痛（Pain out of proportion），且疼痛程度不隨止痛藥或抬高患肢而改善。這是神經血管組織缺氧的早期徵兆。選項 D、C、A 皆與典型病徵相反（腔室症候群應為皮膚冰冷、蒼白、脈搏減弱、感覺麻痺）。
Pain out of proportion to the injury is the earliest and most critical sign of acute compartment syndrome, often unrelieved by standard analgesics. Other classic indicators include paresthesia, pallor, and diminished pulses, rather than increased sensation or warmth.
