Pretty pathways to pain:  Muscle activation in high-heeled shoes
Pretty pathways to pain: Muscle activation in high-heeled shoes
Researchers from New York University have found that wearing high heels increases muscle activation, which can have painful ramifications throughout the kinetic chain. Some individuals, however, seem to adapt to high heels more effectively than others. By Smita Rao, PT, PhD, and Renata Ripa, MA

Evidence-based orthotic management of PTTD
Evidence-based orthotic management of PTTD
The medical literature supports the use of orthotic devices in patients with pos­terior tibial tendon dysfunction, especially those in the early stages. Demonstrated benefits include improvements in foot and ankle alignment, clinical symptoms, and functional outcomes. By Holly Olszewski, CPO
Experts stress selectivity in advanced ulcer care
Experts stress selectivity in advanced ulcer care
Despite the expense associated with advanced wound care technologies, evidence suggests that switching from standard care makes both clinical and economic sense if a diabetic foot ulcer has not experienced a 50 percent reduction in wound area after four weeks. By Emily Delzell
Role of physical therapy in patients with hip OA
Role of physical therapy in patients with hip OA
Some studies support the effectiveness of physical therapy for reducing pain and improving function in patients with hip osteoarthritis, but evidence on the topic is limited and contradictory—suggesting that perhaps PT is most effective in a specific subgroup of patients. By Alexis A. Wright, PT, PhD, DPT, and Garrett S. Naze, PT, DPT
Bracing and rotation, part 2: ACL injuries
Bracing and rotation, part 2: ACL injuries

Preventing wrong-site foot and ankle surgery
Preventing wrong-site foot and ankle surgery
Wrong-site surgery can have significant financial and professional conse­quences, which is why surgeons’ or­gan­iza­tions are promoting protocols speci­­fi­cally designed to reduce such errors. A recent survey of foot and ankle surgeons suggests those efforts are paying off. By Donald E. Fowler III, MD; Karl M. Schweitzer Jr, MD; Olubusola Brimmo, MD; Ryan May, BS; and Selene ...
Chronic ankle instability affects postural control
Chronic ankle instability affects postural control
Research suggests that individuals with chronic ankle instability use different movement strategies to maintain postural control than individuals with healthy ankles. These changes may be related to alterations in movement variability associated with ankle instability. By Lisa Chinn, MS, ATC, and C. Collin Herb, MEd, ATC
