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 ⁣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. (J Korean Acad Rehab Med 2005; 29: 413-418)
