A study published in the July issue of the American Orthopaedic Foot and Ankle Society’s journal, Foot and Ankle International, found no significant difference in the incidence of stress fractures, ankle sprains or other foot problems between the users of expensive custom made foot orthoses and those who used prefabricated orthotic devices.
Foot orthoses are devices worn within shoes that allow the foot to function better. They are usually prescribed to treat specific existing foot conditions, or are used in an attempt to prevent the development of a musculoskeletal problem. Foot orthoses may be fabricated from soft or semi-rigid materials, or a combination of both.
In the study, researchers dispensed foot orthoses among four groups of Israeli infantry recruits to determine how shoe orthoses fabrication affects user comfort and the incidence of overuse injuries in a normal physically active healthy young male population. Recruits were blinded in the study as to whether they trained in custom orthoses or prefabricated orthoses. Both were made of identical materials. Group 1 consisted of 227 recruits given soft custom orthoses. Group 2 consisted of 224 recruits given soft prefabricated orthoses. Group 3 consisted of 215 recruits given semi rigid biomechanical orthoses. Group 4 consisted of 208 recruits given prefabricated semi rigid orthoses, (the study of group 3 and 4 was done at a separate Army base).

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
