Wound Healing And Mechanical Stress
A new study demonstrates that mechanical forces affect the growth and remodeling of blood vessels during tissue regeneration and wound healing. The forces diminish or enhance the vascularization process and tissue regeneration depending on when they are applied during the healing process. The study found that applying mechanical forces to an injury site immediately after healing began disrupted vascular growth into the site and prevented bone healing. However, applying mechanical forces later in the healing process enhanced functional bone regeneration.
For Knee Replacements And Other Medical Devices, One Size Does Not Fit All
Undergoing a knee replacement involves sophisticated medical equipment, but innovative prosthetic design may not offer the same benefits for all knee replacement recipients, Yale School of Medicine researchers report in a perspective article in the October 20 issue of New England Journal of Medicine. Devices like pacemakers, artificial joints, and defibrillators have extended lives and improved the quality of life for countless people. Medical device manufacturing has turned into a multi-billion dollar industry, with the United States spending an estimated $95 billion on these devices last year alone, according to the article, which also noted that oversight of device innovation is under scrutiny for safety issues.
Running Injury Clinic Researchers Examine Effectiveness Of Shoe Inserts
It's one of those mysteries that has baffled runners and running doctors for decades: Why do orthotics work? Orthotics are commonly prescribed for painful conditions like plantar fasciitis, and, anecdotally, people swear by them, however scientists aren't exactly sure how they work. A recent study by University of Calgary Faculty of Kinesiology researcher Reed Ferber, PhD, published in the Journal of Foot and Ankle Research, suggests that to this point, scientists have been measuring the wrong thing.
