<p>A technique for applying therapeutic heat to a skin surface area of a patient whose threshold of sensitivity is determined by that temperature level of the heating medium to which the patient is continuously exposed, above which the patient experiences discomfort. In this technique, the skin surface area is exposed to a heating medium whose temperature is at a base level that is well above ambient but no higher than the temperature sensitivity threshold, the temperature of the medium being periodically raised above the base level to create high heat energy pulses whose peaks are much higher than the threshold. The duty cycle of the pulses is such as to allow for internal heat transfer to take place in the region below the exposed area of the patient in the intervals between pulses to an extent preventing an excessive rise in temperature at the skin surface whereby the patient gains the benefit of high heat energy treatment without discomfort or injury.</p> |
