Pulse mode
Continous mode
Pulsed mode of US results in nonthermal effect i.e., micro massage like which lead to segmental analgesia due to decreased central & peripheral sensitization. The non-thermal effect of US can be explain by frequency resonance theory which states that the proteins in these structures absorbs mechanical energy thus altering the structure & function, finally resulting in stimulation of phagocytosis, increase number of free radicals, increase cell membrane permeability, cellular proliferation &acceleration of fibrinolysis
Thermal effect which is a result of continuous mode of US therapy causes transient increase in the flexibility of collagenous structures including ligaments, tendons & joint capsules, thus leading to decrease in the pain & muscle spasm, stiffness of the joint & temporary increase in the blood flow.
