Structured PICO

Population

Cat skeletal muscle (sympathetic nerves)

Intervention

Electrical vasoconstrictor fibre stimulation in bursts (1 s duration) at varying intra-burst impulse rates (5 to 160 Hz) at constant burst interval (5 or 10 s), or at varying burst intervals (32 to 2 s) at constant intra-burst frequency (16 or 32 Hz)

Comparator

Continuous stimulation at rates from 0.5 to 16 Hz

Outcome

Responses of the resistance and capacitance vessels (constriction)surrogate

Sympathetic burst stimulation effectively controls vascular resistance and capacitance in cat skeletal muscle, suggesting physiological discharge rates may exceed the previously believed upper limit of 10 Hz.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Burst patterns sustain feline muscle vasoconstriction; leaves open translation to human sympathetic discharge rates or vasomotor therapies.
