Therapeutic ultrasound has been used for various healing such as to treat injuries like muscle strains or runner's knee for a long time. However, the controversy on it still continues. There is limited evidence to support or refute its effectiveness and safety. Therapeutic ultrasound is not difficult to test, and present studies are not enough to persuade people that it works well. A recent study showed that it is unambiguously negative to us (Gam & Johannsen, 1995; Brosseau, Casimiro & Robinson et al, 2001).

Some studies (Lehmann & Lateur, 1982; Payton, Lamb & Kasey, 1975; Dyson, Pond, Woodward & Broadbent, 1974) suggested that therapeutic ultrasound should not apply to the eye in physiotherapy procedures as he lens has limited means (due to being avascular), for removing heat and has a relatively high absorption coefficient. Also, irradiation should not applied to any region of significantly diminished blood circulation, except at low intensities where wound healing may be
