Radiofrequency Hyperthermia Safety Study (RHySS)
In Brief
A clinical study evaluating Laser Doppler, Radiofrequency Heating System, and 2 other interventions for Chronic Pain and 3 related conditions. Completed, enrolled 20 participants across 1 site.
Detailed Summary
This study will include 20 healthy subjects with intact skin on their lower legs that meet inclusion criteria. Participants will serve as their own control, by heating one leg and not the other. The radiofrequency device consists of a 4 by 6 inch heating pad connected to a temperature controller. Subjects will receive weekly treatments for 4 weeks, and will be re-evaluated 4 weeks after the last treatment to assess any tissue changes that continue after the treatments have concluded.
Study Details
Timeline
Interventions
Study team will use a PeriScan PIM 3 System Laser Doppler to scan for blood perfusion before and after the Thermofield treatment. The PeriScan PIM 3 System is for non-invasive two-dimensional imaging of peripheral tissue.
The radiofrequency will be set to achieve 42°C/107.6°F) and maintain this temperature consistently during the application time. This temperature is mild and may feel like a drugstore heating pad. The device will be turned on on one leg and will remain off on the other. The time for the heating will be 36 minutes, during which participants will remain in a reclined position, with their legs elevated. The device takes approximately 6 minutes to achieve a tissue temperature of 42°C, and the treatment time with consistent temperature application will be 30 minutes.
Study team will take thermal imaging photographs of the treatment area following each treatment.
A survey tool created to collect info from participants including: 1. Name 2. Age 3. Weight/ height 4. Pregnant or nursing? 5. History of blood clots? 6. Any wound healing problems? 7. Any active open wounds on the legs? 8. Any autoimmune disorders? 9. Phone number 10. Email address A measurement of the participants calf will be taken as well using a measuring tape.
