Abstract: Objective To observe the variation of the blood pressure in patients with persistent vegetative state (PVS) during whirlpool- bubble bath. Methods 5 PVS patients accepted whirlpool-bubble both therapy, 38 ℃ for 20 minutes. Their blood pressure was recorded 0, 10 and 20 minutes after immersing for 4 weeks.
