More energy is required to raise the temperature of tissues with a high specific heat to the same level than those with a lower specific heat. Tissues of high specific heat hold their heat longer. Look at table 6-1 on page 126. Radiation - Heat transfer directly without the need for an intervening medium. Evaporation - Heat transfer due to absorption of energy as a result of conversion.
Collagenous tissue includes tendons, ligaments, scar and joint capsules.
Increased ROM and a decrease in joint stiffness are possible after clinical heat applications. Any increase in enzyme rate will increase the cellular biochemical processes and the uptake of oxygen resulting in accelerated healing Increase of tissue temperature shifts the oxygen-hemoglobin dissociation curve to the right which releases more oxygen for tissue repair. Obtain subjective history and assess skin temperature and color. Over areas of recent or potential hemorrhage Obtain subjective history and visually inspect for ecchymosis. Do not apply heat for the first 48-72 hours after ecchymosis became present or bleeding stopped.
