A Finer Pointe: Visualizing the ankle’s response  to ballet’s toughest task
A Finer Pointe: Visualizing the ankle’s response to ballet’s toughest task
The use of detailed orthopedic imaging to examine dancers’ ankles while in the en pointe position offers insight into the biomechanical demands associated with a position that, although highly unnatural, is nevertheless essential to a ballerina’s performance. By Jeffrey A. Russell, PhD, AT, FIADMS

Out on a limb: Subjectivity & sensitivity
Listening to what patients have to say is an important part of healthcare. But, 
as research continues to demonstrate, it’s no substitute for objective measurements. By Jordana Bieze Foster

Foot06-16-coverSmall muscles, huge potential

In recent years there’s been a lot of study and discussion—some of it quite contentious—of the relative merits of running barefoot, in minimalist shoes, or with various foot-strike patterns. But it seems to me that these debates are distracting foot specialists from a more important aspect of this research: the clinical implications of intrinsic foot muscle weakness.

Golf swing biomechanics: Footwear considerations
Golf swing biomechanics: Footwear considerations
With the rise of a new crop of young stars and the anticipation of its Olympic debut this year, golf continues to be immensely popular for players and spectators alike. Golfing is a highly coordinated sport that, by its nature, is associated with risk of… By Patricia Pande, MClScPT, CSCS, CPed
When knee OA research becomes legal testimony
When knee OA research becomes legal testimony
In worker’s compensation cases, including those involving knee osteoarthritis, an expert witness often will be asked to use his or her knowledge of biomechanics to provide an opinion supporting or refuting a causal relationship between work conditions and an overuse injury. By Steven T. McCaw, PhD
Stroke rehab: Strategies to improve gait velocity
Stroke rehab: Strategies to improve gait velocity
Multiple techniques can help improve gait speed after stroke, from therapeutic exercise to task-specific training to orthotic devices. Despite a growing body of research in this area, however, it is still not clear which intervention is most appropriate for which patients. By Hank Black
Posture-specific strength  and landing mechanics
Posture-specific strength and landing mechanics
Recent research suggests that training designed to maximize strength at deeper knee flexion angles during landing may be warranted, especially in female athletes, to help reduce the risk of anterior cruciate ligament injury without inadvertently compromising jump height. By Boyi Dai, PhD; Jacob S. Layer; and Taylour J. Hinshaw
Treatment of distal toe calluses and ulcerations
Treatment of distal toe calluses and ulcerations
When calluses or ulcers develop on the distal aspect of the lesser toes, offloading pressure from the distal end of the digit is essential for healing to occur. Research suggests that toe crest pads offer an inexpensive but effective means of offloading and healing these distal wounds.    By Monica Melo, DNP, RN, ACNS-BC, CWOCN, CFCN
