Head-Up Tilt response: Might it be conditioned? A Pilot Study

The purpose of this study was to measure the major arterial hemodynamic responses to head-up tilt in the conscious dog. After recovery from surgery for instrumentation, and after habituation to tilt, the dogs were tilted from horizontal to 75 degrees for 5 min. The arterial hemodynamic response after the initial cardiovascular adjustments to the tilt consisted of no change in heart rate and significantly increased arterial blood pressure, with significantly reduced stroke volume and cardiac output. Both renal blood flow and terminal aorta blood flow declined significantly, even more than cardiac output. Muscular exertion was not part of the tilt response because upright standing on the hindlimbs elicited a sustained increase in heart rate and a significantly smaller increase in estimated total peripheral resistance. When compared with the orthostatic response in humans, the increase in arterial pressure was exaggerated in the dogs.

Purpose This pilot study explored the effectiveness of an early storybook reading (ESR) intervention for parents with babies with hearing loss (HL) for improving (a) parents' book selection skills, (b) parent–child eye contact, and (c) parent–child turn-taking. Advancing research into ESR, this study examined whether the benefits from an ESR intervention reported for babies without HL were also observed in babies with HL. Method Four mother–baby dyads participated in a multiple baseline single-case experimental design across behaviors. Treatment effects for parents' book selection skills, parent–child eye contact, and parent–child turn-taking were examined using visual analysis and Tau-U analysis. Results Statistically significant increases, with large to very large effect sizes, were observed for all 4 participants for parent–child eye contact and parent–child turn-taking. Limited improvements with ceiling effects were observed for parents' book selection skills. Conclusion The findings provide preliminary evidence for the effectiveness of an ESR intervention for babies with HL for promoting parent–child interactions through eye contact and turn-taking.
