COLDFLEX® Facts & Comparison Charts / Graphs

- Nihon Medico, Ltd., Tokyo Office

  • In the case of the COLDFLEX treatment, muscle temperature dropped gradually for 1-hour, reaching a temperature after 1-hour of 10 degrees C, and remaining at that level unchanged for 10 hours.  Skin temperature displayed the same pattern, retaining cooling over a long period of time.  Temperature difference between the skin and muscles was only 1.5 degrees C, with little difference between experimental subjects. 

  • On the other hand, rapid temperature drops were frequently observed after initiation of cold pack treatment, with results differing among the subjects.  The drop in temperature did not exhibit a single pattern, and the pattern differed over time.  We believe that the uneven cooling results from inadequate fixation of cold packs to the skin surface.  Moreover, cold pack treatments are limited to 1-hour in duration.  Only the body surface is thoroughly cooled, not the muscles underneath.  While the skin cools rapidly, it returns to its normal temperature within 20 minutes after the treatment is stopped, and we believe the effectiveness is short-lived.  In contrast, the results demonstrate the effectiveness of the COLDFLEX treatment over a period of more than 10 hours.
  • With the COLDFLEX treatment, M Wave amplitude showed an upward pattern after 4 hours of treatment, while Torque amplitude showed a downward pattern.  Thus, the ratio of Torque to M Wave (T/M) tended to increase, indicating a condition of favorable muscle contraction.

  • Results from the cold pack treatment showed a similar pattern to that of the COLDFLEX treatment, but there was a substantial fluctuation in the M Wave and Toque amplitude, particularly the latter.  As a result, the T/M ratio increased greatly, indicating a condition of unfavorable muscle contraction.  These results clearly contrast the ill effects of rapid cooling (cold packs) with gradual cooling (COLDFLEX).  Our results suggest that a slow, steady cooling over a long period of time produces the most favorable results in terms of nerve and muscle response.
  • The results of these experiments show that theCOLDFLEX treatment achieves effective cooling, and that it is able to maintain a set level of cooling over an extended period of time.  The COLDFELX shows superior systemic muscle temperature cooling properties, and its use would be desirable after vigorous sports or exercise such as soccer, when it could be used both after the match and at halftime.  Our results also show that the COLDFLEX treatment is effective in alleviating inflammation of muscles, joints, ligaments and other connective tissues produced by sports activities.
