The Effect of ICE on Intramuscular Tissue Temperature
Ice, compression, and elevation, or ICE, is a widely used treatment for acute musculoskeletal injuries. The effects of ice and compression on tissue temperatures have been established but whether elevation during cryotherapy affects temperature change has not. Elevation has potential to alter local perfusion and thereby alter the balance of heat loss/heat gain, potentially impacting tissue cooling during cryotherapy.
To measure the effect and interaction of ice, compression, and elevation on intramuscular temperatures. We hypothesized that elevation would not have an effect on intramuscular tissue temperature.
Fifteen healthy volunteers, (age 20.93 ±1.67) provided informed consent and participated.
Participants completed eight treatment conditions including: No treatment (control), ice only (I), compression only (C), elevation only (E), ice and compression (IC), ice and elevation (IE), compression and elevation (CE), or ice, compression and elevation (ICE). All conditions were tested on each participant with a minimum of 48 hours between each condition. Intramuscular temperatures were recorded every 30 seconds during a 1 minute pre-application, 30 minute treatment, and 20 minute post-application period.
The temperature difference between the mean treatment temperature and the mean pre-application temperature was compared across each measurement depth and treatment conditions.
Non-ice treatments (Control, C, E, and CE; means 33.4, 34.5, 33.7 and 34.6, respectively) had warmer intramuscular temperatures than any treatment that included ice (I, IC, IE, ICE; means 28.4, 19.8, 28.0, and 19.3, respectively). There were no differences between IC and ICE (means 19.8 and 19.3, respectively). Ice alone was different than everything except IE.
