The Effect of a Biofeedback-Based Integrated Intervention for Older Adults with Orthostatic Hypotension: A Secondary Analysis on Psychological Health Outcomes in a Non-Randomized Pilot Trial.

Background/objectives: Aging-related physical changes and dysfunctions in the autonomic nervous system (ANS) often lead to orthostatic hypotension (OH) in older adults. OH negatively impacts both the physical and psychological well-being of those affected. Previous studies have demonstrated that the biofeedback-based integrated program (BBIP), a multicomponent intervention focused on heart rate variability biofeedback, effectively improves OH, as well as symptoms related to ANS function. This substudy aims to examine the effects of the BBIP on psychological health outcomes among community-dwelling older adults with OH.

Methods: This study employed a non-randomized controlled trial design with a convenience sampling strategy. A total of 51 older adults with OH were recruited from two senior welfare centers and randomly assigned to either the intervention group (n = 27) or the control group (n = 24). The intervention group participated in a 12-week BBIP, which included weekly biofeedback sessions and group education on lifestyle modification to alleviate OH. Telephone counseling was also provided to promote compliance.

Results: The intervention group showed significant improvements in health-related quality of life, depression, anxiety, and fall efficacy after the 12-week BBIP, whereas the control group exhibited no significant changes. There was a significant reduction in the percentage of participants in the intervention group reporting problems in all five dimensions of the EQ-5D (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression).

Conclusions: The BBIP was effective in improving the psychological health outcomes of older adults with OH. Future studies should explore the long-term effects of the BBIP using a larger sample size and a randomized controlled trial design.
