and another variation, timing is a little different.
The second approach, which is preferred by this author, is contrast therapy. Assuming the absence of vascular damage and thrombosis, the contused area is treated with moist cryotherapy. This may be by moist ice bag, frozen silicone gel wrap, or a vessel containing ice water depending upon the appropriateness of anatomical part being treated relative to the method chosen. The moist cryotherapy is applied for no more than 10 to 15 minutes ensuring the absence of cyanosis of the region being treated. Immediately following moist cryotherapy, the part is then transferred directly to moist heat. This may be by moist heated silicone gel wrap, moist hot pack, or a vessel of warm water. Application of the thermal agent is maintained for five to eight minutes, after which the part is once again transferred to the moist cryotherapy for 10 to 15 minutes, again ensuring the absence of cyanosis, after which it is again transferred to the thermal agent. The final agent used prior to discontinuing the treatment process should be moist cryotherapy.
