Average and standard deviation of relative (DSCA)- and absolute (ECG) PSD distributions for VLF, LF, and HF, according to baseline, occlusion, and release periods in all subjects during 90° head up tilt posture. Note that DSCA data was obtained from channel 4. *P < 0.05 compared to baseline period.
