M.E.L.T.S
types of energy
potential and kinetics
calories
heat energy needed to increase the temperature of a single gram of water by one degree Celsius
radiation
no contact is made
eg laser
infrared
diathermy
convection
transfer heat between circulating medium
eg fluidotherapy
conversion
of non-thermal energy
eg ultrasound and diathermy
superficial heaters
ultrasound
infrared
fluidotherapy
hot packs
noradrenergic
vasoconstrictor system
cholinergic
vasodilator system
sensory receptors in sub epithelial tissue
cold
warm
pain
thermal signals trigger vasomotor centers in
hypothalamus
muscle strength and endurance decrease and recovery time
decrease for initial 30 min
increases for next 2hrs
latent heat of fusion
specific amount of energy required to change a solid form of particular substance into liquid, or liquid into gas
5 stages of cold
