The three most frequently reported factors that would lead to the clinical decision of the physiotherapist not to clamp the extraventricular drain (EVD) for mobilisation were new signs of neurological deterioration (n=48/52, 92%), medical clearance from either neurosurgeon or intensivist not being given (n=48/52, 92%) and if intracranial pressure was greater than 20mmHg (n=42/52, 81%).
