This study will investigate the safety and feasibility of early intensive physical therapy for patients diagnosed with subarachnoid hemorrhage. Intervention will begin in the neurological Intensive Care Unit (ICU) and continue for 30 days or hospital discharge.

Inclusion Criteria:

• Patients diagnosed by CT scan or MRI with subarachnoid hemorrhage and admitted to the neurological ICU >48 hours.

Exclusion Criteria:

• Significant language barrier that would limit the ability to participate in the physical therapy program

• Severe baseline physical or cognitive impairment that would impair their ability to participate in the protocol

• Patients whose vital signs are outside the accepted starting and stopping criteria outlined below:

  1. intracranial pressure ≤ 15 mm Hg
  2. Cerebral perfusion pressure >50 or <70 mm Hg
  3. Mean arterial pressure ≥ 80 and ≤ 110
  4. Heart rate ≥40 and <140 bpm
  5. Pulse oximetry >88%
