The ability of the object to conduct heat is known as its thermal conductivity, and is denoted k.. Heat spontaneously flows along a temperature gradient (i.e. from a hotter body to a colder body). For example, heat is conducted from the hotplate of …
WebIn this study, heat-conduction dry needling therapy, a kind of physical thermotherapy, was used to heating lesions to 44°C for treating CMPS and determining the role of TRPV1 pathway. Our results demonstrated that heat-conduction dry needling therapy altered the expression of TRPV1 mRNA and modulated its activity.
