Ultrasound for Healthy Aging

Purpose

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.

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.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
Ultrasound Spa Group
Sessions will take place three times per week, with water-based delivery of low-frequency ultrasound lasting 45 minutes each, for a total of eight weeks.
  • Device: Ultrasound spa
    Each participant will sit in a bathtub which has been fitted with an ultrasound device which produces low frequency sound waves within the water.
    Other names:
    • Bathtub with ultrasound
Sham Comparator
Spa Only Group without ultrasound
Sessions will take place three times per week, with spa immersion with no ultrasound lasting 45 minutes each, for a total of eight weeks.
  • Other: Sham ultrasound spa
    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.

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.
