Effects of Ultrasound on Wound Contraction
Wound contraction is the reduction of part or all of a skin defect by centripetal movement of the surrounding undamaged skin(1). It plays an important part in wound healing, the restoration of continuity in living tissue, since it reduces the size of the tissue defect. The edges of the lesion move inwards and the stretched healthy skin beyond the lesion responds by interstitial growth. Wound contraction appears to be brought about by the shortening of linked myofibroblasts and to be maintained by the deposition of collagen fibers in the granulation tissue which develops at the wound site.
