냉기치료 적용방법에 따른 슬관절강 내 온도 변화

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 -30oC cold jet-stream by CRAisⓇ (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±0.6oC (p＜0.01) and it took 28.7±18.9 minutes. Intraarticular temperature dropped 0.6±0.5oC after 2 hour (p＜0.05). In CCAI, the intraarticular temperature maximally dropped as 2.8±0.7oC (p＜0.01) and it took 38.0±24.6 minutes, intraarticular temperature after 2 hour dropped as 1.36±0.75oC (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. KCI Citation Count: 0
