In general, the more convenient the modality is to use for the patient or family, the more likely it is that they will use it. An additional important factor, to consider when making a recommendation to a patient, is the cost of the modality. At this time, there is no conclusive evidence that one type of heating modality for patient self application is more effective than another. Thus, convenience and cost are the factors to consider when recommending a heat modality to a patient or family. Any discussion of heat modalities must include an appropriate warning to patients and families.
Many individuals incorrectly believe the hotter the heat the better.
This unfounded notion is dangerous and can lead to unnecessary complications. During heat application, the patient should note a comfortable, soothing warmth. Immediately after heat application, the skin of the patient should be carefully checked. The pinkish-red color of the skin should slowly dissipate, and should be completely gone within an hour. Blisters signal a second degree burn, and heat application at this site must cease and the patient's physician should be notified.
