A quadriceps isometric contraction exercise method is effective for relieving pain in knee osteoarthritis (OA), according to a study published online May 25 in the International Journal of Rheumatic Diseases.
Devoted runners suffer from a surprisingly high rate of injury. One reason for these injuries is that runners endure many shocks from the impact, and these cause vibrations that travel from the foot throughout the entire body. A researcher who focuses on acoustics and biomechanics, studied these repetitive shocks and investigated how runners adapt their running patterns.
Highly competitive youth leagues have largely replaced more laid-back pickup games. Kids are increasingly specializing in a single sport year-round, rather than bouncing from one game to the next with long, languid off-seasons in between. Experts say that fundamental shift in how kids and parents approach sports – and how much kids play – may have consequences when it comes to a child or adolescent’s risk of injury.

The journal is published in partnership with Wolters Kluwer.
Patients who underwent primary shoulder arthroplasty experienced a significantly higher risk for infection if they had previously undergone non–arthroplasty-related surgery, according to results.
