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.

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.

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.

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.

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.

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.
