OBJECTIVE A prospective patient study was done to evaluate the effect of passive range of motion (PROM) on intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in neurosurgical patients. METHODS Twelve adult patients admitted to the neurological-neurosurgical intensive care unit of a community teaching hospital were enrolled in the study. The study patients all required ICP monitoring and they underwent a total of 20 PROM sessions. Six patients (10 PROM sessions) were mechanically ventilated, and six patients (10 PROM sessions) were breathing spontaneously. Mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), and ICP were measured at baseline and at 1-minute intervals during the physical therapy session. CPP was calculated as the difference between MAP and ICP. RESULTS No significant changes were detected in MAP, ICP, HR, or RR during the study period. Calculated CPP remained unchanged. Mean duration of PROM intervention was 7 +/- 1 minute. Mean Glasgow Coma Scale (GCS) for mechanically ventilated patients was 7 +/- 1.3 and for spontaneously breathing patients 13 +/- 0.8. CONCLUSIONS PROM results in no significant changes in ICP or CPP in stable, neurosurgical patients in the absence of intracranial hypertension.

D012119	Respiration	The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.). This does not include tissue respiration (	Breathing
D012121	Respiration, Artificial	Any method of artificial breathing that employs mechanical or non-mechanical means to force the air into and out of the lungs. Artificial respiration or ventilation is used in individuals who have stopped breathing or have RESPIRATORY INSUFFICIENCY to increase their intake of oxygen (O2) and excretion of carbon dioxide (CO2).
