July's issue of Clinics in Sports Medicine is dedicated to the Runner and guest edited by Dr. Robert Wilder, Associate Professor of PM&R and Medical Director of the Runner's Clinic at the University of Virginia. Dr. Wilder and a team of expert contributors discuss all aspects of running, including biomechanics and kinematics, flexibility, exertional compartment syndrome, patellofemoral pain syndrome, stress fractures, exercise-associated collapse, and more. Several chapters focus on special considerations for certain types of runners: children, women, injured runners, and those with osteoarthritis.
