Breaking pointe: Foot and ankle injuries in dance

Essential to the beauty of dance are the demanding biomechanics of the dancer, particularly at the foot and ankle. Injuries and pain are almost inevitable. But an understanding of the underlying issues—artistic as well as anatomical—can help practitioners keep dancers on their toes for as long as possible.

Out on a limb: Next top model

I grew up in Portland, OR. I live in New England. That means I root against all of the Los Angeles Lakers. But I do find Kobe Bryant’s footwear fascinating.

Knee bracing benefits off-road motorcyclists

New research suggests that serious injuries occur as frequently in off-road motorcycle racing as they do in football, but such injuries occur less frequently in riders who wear knee braces.This may be why, although it is not well studied, knee bracing is widespread among off-road motorcycle riders.

Adult acquired flatfoot: Nonoperative options

Adult acquired flatfoot deformity, primarily posterior tibial tendon dysfunction, in many cases can be successfully managed with conservative treatment modalities including early immobilization, long-term bracing, physi­cal therapy, and anti-inflam­matory medications.

Knee OA: The evidence for gait modification

Gait retraining can potentially alter walking biomechanics such that knee adduction moment is reduced, an inexpensive off­loading option that does not require device wear. Gait modification studies to date have primarily focused on foot rotation, trunk lean, and knee medialization.

Biomechanical analysis of ankle sprain ‘copers’

Researchers are investigating why some people develop chronic ankle instabilty after a sprain while others seem to heal normally. Biomechanical differences between the two cohorts may offer clues to the mechanisms underlying CAI and enhance preventive efforts.

Monofilament testing withstands critiques

Experts continue to debate the relative merits of the Semmes-Weinstein mono­fila­ment for assessing diabetic foot ulcer risk, including how many sites on the foot should be tested, and which ones. But it’s tough to argue with the technique’s cost-effectiveness.

Charcot-Marie-Tooth patients delay using prescribed ankle foot orthoses
Even if they have a device prescription, individuals with Charcot-Marie-Tooth disease tend to put off wearing ankle-foot orthoses (AFOs) until walking function is impaired, according to research conducted at St. George’s University of London and Kingston University, London. Investigators compared presentation ...
Muscle activation data suggest gap in poststroke gait rehabilitation
Improving gait and coordination among stroke survivors should involve developing rehabilitation techniques that target abnormal muscle timing characteristics, suggests recent research from the Louis Stokes Cleveland VA Medical Center, OH.

Shear significance
Study delves beyond plantar pressure – Recent research confirms that peak shear and peak pressure points occur at different locations under the foot, shedding some light on the role of shear in diabetic foot ulceration. By Emily Delzell
Metatarsal pads may reduce pain by creating space in the forefoot
A Dutch study suggests that metatarsal pads relieve metatar­salgia pain by creating space between metatarsal heads in addition to reducing plantar pressure. Researchers from St. Maartens Clinic in Nijmegen, the Netherlands, performed motion analysis on 16 feet with primary metatarsalgia and ...
Peroneal response to inversion increases with shoe sole thickness
Wearing thick-soled shoes increases the magnitude of peroneus longus muscle activity required to resist an unanticipated foot inversion, elevating the risk of an ankle sprain, according to research from the University of Dundee in Scotland. Investigators used electromyography to assess peroneus ...
