In the United States, September is associated with returning to school. This month's PTJ provides many opportunities for physical therapy educators to refer to outstanding research, says Editor in Chief Rebecca Craik, PT, PhD, FAPTA, in her monthly Craikcast podcast. Craik also urges faculty and students to listen to the 43rd Mary McMillan Lecture, "Face the Storm," presented by Alan Jette, PT, PhD, FAPTA, in June at APTA's annual conference.
Research topics in the September issue include predictors of chronic nonspecific low back pain, physical activity after total knee replacement, prevalence of McKenzie's classification categories among patients with extremity problems, walking activity in people poststroke compared with older adults without disability, and the use of electromagnetic fields used in stem-cell tissue engineering. Full text and a podcast of the 2012 APTA Presidential Address, delivered by R. Scott Ward, PT, PhD, also are available.
