Abstract:
OBJECTIVE: To investigate the changes of intraarticular temperature in the knee according to the application methods of cold jet-stream and to find the more effective method which reduces the intraarticular temperature. METHOD: Fifteen healthy subjects were examined. We recorded both skin and intraarticular temperature of the knee for 120 minutes. We compared two different cooling methods using -30 degrees C cold jet-stream by CRAis(R) (Century, Korea). The first was the intermittent cold jet-stream application method (ICA) which applied cold jet-stream to the knee joint every other minute for 5 minutes and the second was the continuous cold jet-stream application method with infrared (CCAI) for 5 minutes. RESULTS: In ICA, the intraarticular temperature maximally dropped as 1.7+/-0.6 degrees C (p<0.01) and it took 28.7+/-18.9 minutes. Intraarticular temperature dropped 0.6+/-0.5 degrees C after 2 hour (p<0.05). In CCAI, the intraarticular temperature maximally dropped as 2.8+/-0.7 degrees C (p<0.01) and it took 38.0+/-24.6 minutes, intraarticular temperature after 2 hour dropped as 1.36+/-0.75 degrees C (p<0.05). According to the two methods, CCAI showed more reduction in the lowest and after 2 hour intraarticular temperature compared with ICA in the knee joint (p<0.05). CONCLUSION: CCAI is better for reducing the intraarticular temperature than ICA.
