Values are mean ± SEM. LF = Low Frequency, HF = High Frequency, nu = normalized. * indicates a significant difference (p < 0.001) within a condition between H1 and Tilt positions; # indicates a significant difference (p < 0.001) between control and OMT conditions and sham and OMT conditions in the Tilt position.Back to article page
