New researchers have found that applying ultrasound can speed up regeneration of broken bone by one third and this can help in restoring memory in a mice suffering from Alzheimer’s disease. The researchers have now found that ultrasound can accelerate wound healing.
People, including the elderly, who suffer from diabetes, are at an increased risk for developing skin ulcers as well as bedsores. Such wounds can lead to major limb amputation if it is not healed in time. The recent animal study that was published in the Journal of Investigative of Dermatology, researchers at the University of Bristol found that a low-intensity ultrasound can help in fastening the time it takes for wounds to heal in aged mice and diabetics by about 30 percent.
While the equipment was not vastly different from has been used since a long time to monitor a fetus during pregnancy, the vibration of sound waves were seen to activate a protein pathway that helped the fibroblast cells–which are important for healing–to migrate to the wound.
The lead author of the study, Mark Bass, said that using ultrasound waves to wake up cells and stimulate them for normal healing helps to speed up normal processes. He further added that the process does not carry any side-effects that have been often linked with drug treatments.
