Why the study?
Does the repeated sit-to-stand method agree with the modified Oxford method for measuring cardiac baroreflex gain in healthy individuals?
Does the repeated sit-to-stand method agree with the modified Oxford method for measuring cardiac baroreflex gain in healthy individuals?
Cardiac baroreflex gain is frequency-dependent, and values derived from repeated sit-to-stand maneuvers cannot be used interchangeably with those from the modified Oxford method.
No takes yet. Share an insight, caveat, or question.
Caution against interchanging sit-to-stand and pharmacological baroreflex gains; supports frequency-specific protocols but leaves validation open.
Horsman et al. (2013) studied this question.
