TMD waveforms generated by the CCFP Analyzer were averaged across all subjects during sitting, supine, HDT, and HDT + LNBP at −25 and −50 mmHg conditions. The sitting TMD moves in the outward direction, after tone stimulation and indicating a low ICP. The supine and HDT conditions caused the TMD to move in the inward direction, and suggesting elevated ICP. Application of 25 and 50 mmHg LBNP during HDT caused the TMD to move outward, relative to HDT, suggesting that LBNP reduced ICP.
