Implication
Feedback may aid short-term BP regulation experimentally; leaves open durability and clinical translation.
Structured PICO
Does exteroceptive feedback improve blood pressure control compared to simple instructions?
P
Population
40 subjects
I
Intervention
Exteroceptive feedback (viewing an analogue visual display of mean arterial pressure) to raise or lower blood pressure for four sessions
C
Comparator
Simple instructions to raise or lower blood pressure for four sessions
O
Outcome
Blood pressure changes continuously monitored with the pulse wave velocity methodsurrogate
Exteroceptive feedback provides superior short-term control of blood pressure compared to simple instructions, though the effect deteriorates upon withdrawal.
