The term laser thermotherapy is an acronym for Light Amplification by Stimulated Emission of Radiation, which first appeared as a term in 1959. Laser thermal therapy was clinically used for tissue ablation in 1966, based on the theory that the energy produced by laser light could achieve a high peak power through a ruby tip and could be absorbed by the surrounding tissue as heat 1).


Steroid myopathy is usually an insidious disease process that causes weakness mainly to the proximal muscles of the upper and lower limbs and to the neck flexors. Cushing originally described it in 1932, and Muller and Kugelberg first studied it systemically in 1959.
