Belsey J, Reid A, Paine E, Faulkner J. A randomised crossover trial of five cryocompression devices' ability to reduce skin temperature of the knee. PLoS One. 2024 Jan 16;19(1):e0296634.
Design: Randomised Crossover Trial.
Subjects: 32 healthy adult participants were recruited
Methods: Skin temperature was measured by a thermocouple every 5 minutes during a 30-minute treatment with one of five different cryocompression devices (Physiolab S1, GameReady, Cryo/Cuff , VPulse, and a Gel Wrap). Outcomes included: Changes in skin temperature. Comfort was also recorded for each device.
Results:
Key message: The Aircast Cryo/Cuff achieved the second highest positive comfort rating (90%), however only the Physiolab S1 and Gameready devices were capable of reducing skin temperature of the knee within the target range of 10-15°C.
• The Physiolab S1, VPulse and GameReady reduced skin temperature significantly at each time point for the first 15 minutes of treatment to 16.1 ˚C, 21.6˚C, 16.7˚C, respectively. • The Cryo/Cuff reduced skin temperature significantly for the first five minutes of the treatment to 24.2˚C; temperature reduction continued after but not significantly. • Only the Physiolab S1 and GameReady were within the target therapeutic range at 30 minutes (13.9˚C and 13.0˚C). Mean skin temperatures for the VPulse, Cryo /Cuff, and Gel Wrap were 17.2˚C, 17.0˚C, and 19.9C, respectively. • 90% reported a positive comfort rating for the Cryo/Cuff, with no negative ratings given. Other devices: 86.7% (Physiolab S1 & Vpulse), 53.3% (GameReady),96.7% (Gel Wrap).
