The Effect of Bedding System Selected by Manual Muscle Testing on Sleep-Related Cardiovascular Functions

Figure 4

Comparisons of spontaneous baroreflex sensitivity across the control, selected weak, and selected strong bedding systems during AW and NREM from noon laboratory PSG and blood pressure recordings. Four indices were used for this analysis: magnitude of transfer function between MAP and RR signals over the frequency ranges of 0.04–0.15 Hz (BrrLF) and 0.15–0.4 Hz (BrrHF) together with the slope of the linear regression between MAP and RR pairs under successively descending (BrrD) and ascending (BrrA) changes. Values are presented as means ±SEM; 𝑛=10. ^∗𝑃<0.05 versus the control bedding system. ^†𝑃<0.05 versus the selected weak bedding system by Fisher’s least significant difference test.
