Four participants were given cervical adjustments when indicated, and 3 were given thoracic adjustments. Pre, Preadjustment; Post, postadjustment; T, total.

⁎Significant differences were seen pre- to postadjustment after cervical adjustments in regard to a decrease in diastolic BP and increase in pulse pressure.
†Comparisons of group receiving cervical adjustments and group receiving thoracic adjustments.
