The Skin Temperature Change of Cold-jet Stream with Infrared Combination Therapy on Buttock

  • 1Department of Rehabilitation Medicine, Hanyang University College of Medicine, Korea.


To investigate the changes of the intramuscular temperature on buttock according to the application methods of cold jet-stream and to find the more effective method which reduces the intramuscular temperature. METHOD: Twenty eight healthy volunteers were examined. Cold-jet stream (CS) was applied on buttock (5 cm below of iliac crest, surface of gluteus medius muscle). We measured the time that skin temperature fall from room temperature to 10 degrees C (first period), the time rewarmed from 10 degrees C to 20 degrees C (second period), the time fall again to 10 degrees C (third period) and the time rewarmed again to 20 degrees C (fourth period). Cold-jet stream with infrared combination (CSIC) therapy was performed with the same method. RESULTS: At the first and third cooling periods, It took longer in CSIC group than CS group to decrease skin temperature. At fourth period, It took longer in CSIC group than CS group to rewarm skin. In CS and CSIC groups, fourth period is longer than second period. CONCLUSION: It took longer in CSIC method than CS only to decrease skin temperature to 10degrees C. Rewarming speed of skin temperature was slower twice cold-jet stream applies than once. Rewarming speed of skin temperature was slower at old-jet stream and infrared combination therapy than cold-jet only.
