Energy efficiency with AFO use varies in cerebral palsy patients

Longer strides lead to increased work
Ankle foot orthoses (AFOs) are regularly prescribed to children with walking disabilities resulting from cerebral palsy, yet the effects of AFOs on energy recovery and work during gait are still unclear.

Biomodel could help researchers optimize clubfoot brace design

Method includes complex rotations
A surrogate biomodel of a child’s lower extremities, in particular the ability to model movement along multiple axes of rotation, could help improve researchers’ biomechanical understanding of bracing for clubfoot.

Juvenile idiopathic arthritis study reveals footcare information gap

Issues involve custom foot orthoses
A Scottish study suggests foot care in children with juvenile idiopathic arthritis (JIA) falls short because of poor access to care and negative perceptions about custom foot orthoses. Experts say those issues may be less prevalent in the US but emphasize the need to educate patients, parents, and referring clinicians about the benefits of lower extremity care.

Early ACL surgery could lower risk of associated knee damage

Patterns mirror those seen in adults
Timing of reconstruction surgery after pediatric anterior cruciate ligament (ACL) injuries seems to be related to the prevalence of meniscal and chondral injuries discovered during those surgeries, according to new research published in the September issue of The American Journal of Sports Medicine.

Dynamic data in obese children may suggest gait compensation

Low force values surprise researchers
An Austrian study exploring the role of genu valgum and flatfoot in obese and normal weight children found obesity was associated with higher peak plantar pres­sures, but lower maximum force while walking, when forces were normalized to body weight.

Experts debate relative benefits of screening feet for risk factors

Most question emphasis on flatfoot
The value of screening programs for pediatric foot problems—primarily flatfoot—was recently challenged in a commentary by Australian podiatrist Angela Evans, PhD, a researcher and lecturer in the Division of Health Sciences at the University of Adelaide.

CONFERENCE COVERAGE: Orthotics Technology Forum 2012

Orthotic laboratory managers, CAD-CAM technology experts, and lower extremity practitioners convened in Manchester, UK, in July to share ideas and experiences related to the automated design and manufacture of foot orthotic devices. Foot orthotic laboratories have long been the principal … Continue reading

Future of Orthotic Design will focus on practitioners

Foot orthotic laboratories have long been the principal players in the computer aided design and computer aided manufacturing (CAD-CAM) of foot orthoses. But practitioners are gradually starting to play a bigger role in the process—a development that dramatically enhances the potential for clinical creativity but also introduces an extra element of uncertainty.

OPTIMIZING ORTHOTIC MILLING

Computer aided manufacturing is anything but a one-size-fits-all proposition. Customers have a range of variables to choose from, and making the right decision in most cases depends on knowing what type of orthotic material the machine will be asked to handle.

High-tech heel pad tissue analysis: Orthotic implications

The use of technology to improve orthotic design is not limited to CAD-CAM applications, as demonstrated by University of Salford researchers in two presentations at the Orthotics Technology Forum.

Additive manufacturing inches toward prime time

The fledgling field of additive manufacturing is still somewhat fragmented, as evidenced by the fact that the same technology can be described as rapid prototyping or 3D printing. But additive manufacturing’s profile is definitely on the rise, and its advocates are optimistic that lower extremity clinical applications are right around the corner.

STEPS AHEAD: Advances in foot and ankle biomechanics

Foot and ankle experts from across the globe gathered in Sydney, Australia, in April for the third International Foot & Ankle Biomechanics (i-FAB) congress. LER’s exclusive coverage of this event starts with the ever-controversial topic of barefoot running and goes on to examine clinical and scientific progress related to plantar pressures, diabetes, pediatrics, unstable shoes, and osteoarthritis.

Biomechanist challenges idea that forefoot strike pattern reduces runners’ injury rate

Cites lack of conclusive evidence – Joseph Hamill, PhD, is an avid runner who runs with a natural forefoot strike pattern. But Hamill, professor of kinesiology at the University of Massachusetts Amherst, says he wouldn’t recommend that running technique for most people, despite recent claims that the forefoot strike pattern associated with barefoot running is associated with a lower risk of injury than rearfoot-strike running.

Footwear customized with pressure data fails to reduce diabetic reulceration rates

But ulcer severity may be decreased – In a Dutch randomized controlled trial of 171 high-risk diabetic patients, using plantar pressure measurements to confirm offloading below 200 kPa did not result in lower rates of ulcer recurrence over 18 months compared to standard custom shoes.

Sham debridement matches scalpel for relief of painful plantar calluses

Scalpel debridement of plantar calluses in elderly patients does not reduce plantar pressures and is no more effective than sham treatment for relieving pain, according to an Australian study.

Factors other than static curve influence rollover shape with rocker-bottom shoes

Data confirm kinetic, EMG changes – The static curve of a rocker-bottom shoe does not correlate strongly with its rollover shape during gait, suggesting that other factors such as material stiffness may also contribute, according to research from the University of Salford in the UK.

New papers revisit, rekindle flexible flatfoot controversy

“Other considerations” spark debate

In January 2010, when LER first covered the controversy, Australian podiatrist and researcher Angela Evans, PhD, had recently published a paper in the Journal of the American Podiatric Medical Association suggesting that children whose feet were flatter than expected, but asymptomatic, should be monitored rather than automatically treated with orthoses.
