Ultrasound for Healthy Aging
Sponsor:

The University of Texas Health Science Center at San Antonio

Information provided by (Responsible Party):

Blake Rasmussen

Brief Summary:

The investigators will study the effects of an ultrasound bath device that uses low-frequency ultrasound on the healthy aging. Participants will have before and after ultrasound assessments of muscle and thinking skills, aging related to the immune system, and body make-up. The group that is assigned to get the ultrasound will have low-frequency ultrasound in a bathtub for 45 minutes, three times weekly for 8 weeks, and the control group will be in the bathtub without the ultrasound turned on.

Phase

NA

Detailed Description:

The general approach and study design is that the investigators will recruit 20 healthy older adults (equal numbers of men and women) for the first phase. 10 participants will be randomized to the ultrasound group and 10 will be randomized to the control group. Participants will be stratified by gender and ten randomized to treatment arms. Prior to beginning the intervention, each participant will be tested for muscle function, cognitive function, blood samples will be used to assess immune aging function, and body composition. Each participant will then sit in a bathtub which has been fitted with an ultrasound device which produces low frequency sound waves within the water. The sound waves are undetectable by someone sitting in the tub. The ultrasound intervention group will receive ultrasound for 45 minutes, 3 times per week for 8 weeks. The control group will sit in the same tub for 45 minutes, 3 times per week for 8 weeks but without the ultrasound being turned on. At the end of the 8 weeks, post-testing for muscle, cognitive, immune aging function, and body composition will be performed again.

Study Type : INTERVENTIONAL
Estimated Enrollment : 20 participants
Masking : SINGLE
Masking Description : This sham-controlled design improves internal validity by minimizing placebo effects and allows for participant blinding, as the ultrasound is inaudible and imperceptible.
Primary Purpose : SUPPORTIVE_CARE
Official Title : Effects of Ultrasound on Healthy Aging
Actual Study Start Date : 2025-10-01
Estimated Primary Completion Date : 2026-10-01
Estimated Study Completion Date : 2026-12-31
