When applying ultrasound therapy a gel is applied to the skin then (using an ultrasound machine) high frequency sound waves are passed through the gel, skin, and into the body over the injured tissue. The theory behind ultrasound is that it will speed up and improve the quality of the recovering or healing tissue.
Currently there is much debate within the scientific and manual therapy community as to the effectiveness of ultrasound with new research often coming to light. Overall, research into the effect on humans and overall function of the injured area are lacking and needs further investigation.
When applied to an injury other treatment methods or ‘tools’ should also be used in an effort to promote a good quality of care and a speedy recovery.
