Botulinum-toxin A (BoNT/A) is used for a wide range of conditions. Intramuscular administration of BoNT/A inhibits the release of acetylcholine at the neuromuscular junction from presynaptic motor neurons causing muscle-paralysis. The aim of the present study was to investigate the effect of high dose intramuscular BoNT/A injections (6 UI = 60 pg) on muscle tissue. The gait pattern of the rats was significantly affected 3 weeks after BoNT/A injection. The ankle joint rotated externally, the rats became flat footed, and the stride length decreased after BoNT/A injection...

Flat foot is one of the common deformities in the youth population, seriously affecting the weight supporting and daily exercising. However, there is lacking of quantitative data relative to material selection and shape design of the personalized orthopedic insole. This study was to evaluate the biomechanical effects of material hardness and support height of personalized orthopedic insole on foot tissues, by in vivo experiment and finite element modeling. The correction of arch height increased with material hardness and support height...

Angel Zeininger, Daniel Schmitt, Jody L Jensen, Liza J Shapiro
The assumption that the morphology of the human calcaneus reflects high and cyclical impact forces at heel strike during adult human walking has never been experimentally tested. Since a walking step with a heel strike is an emergent behavior in children, an ontogenetic study provides a natural experiment to begin testing the relationship between the mechanics of heel strike and calcaneal anatomy. This study examined the ground reaction forces (GRFs) of stepping in children to determine the location of the center of pressure (COP) relative to the calcaneus and the orientation and magnitude of ground reaction forces during foot contact...

Between 20 and 45% of women aged over 65 years of age will develop one or more foot problems, which, although not specific to older women, are more common in that age group than in younger women. These include structural defects of the toes including hallux valgus, hammer, mallet or claw toes, skin disorders, fungal infection of the toes and toe nails, thickened toe nails, ulcers, fissures or cracks between the toes, corns and calluses, flat or high-arched feet. Foot pain is common and may be associated with other co-morbid diseases of the foot...

Due to the problem of tick-borne diseases, there is a need to better understand the importance of different host species in maintaining enzootic disease cycles. We explored the utility of stable isotope analysis to identify the larval hosts of questing ixodid ticks. In laboratory experiments, we used Ixodes scapularis and two host species that are important in the Lyme disease system in eastern North America. First, we tested how effectively a short-term dietary tracer ((13)C in corn) was reflected in molted ticks...

We present a case of fibular insufficiency (stress) fracture in a patient with pre-existing asymptomatic advanced tibialis posterior dysfunction. The patient had severe planovalgus (flat foot) deformity but no pain before the injury; hence had never sought any treatment. She was first treated conservatively for the fracture which failed to control the deformity and had ongoing symptoms. She eventually required tibio-talo-calcaneal fusion. To the best of our knowledge, this is the first case report of this condition in the English literature...

BACKGROUND: All typically developing children are born with flexible flat feet, progressively developing a medial longitudinal arch during the first decade of their lives. Whilst the child's foot is expected to be flat, there is currently no consensus as to how flat this foot should be. Furthermore, whilst feet are observed to decrease in flatness with increasing age, it is not known how flat they should be at each age increment. The objective of this systematic review is to define the postural characteristics of the 'typically' developing paediatric foot...

REVIEW
Ezekiel Oburu, Mark S Myerson
Deltoid ligament reconstruction allows for joint preservation of the ankle in the setting of patients a triple arthrodesis due to a flat foot deformity. Although the increased forces that may occur in the ankle joint after a triple arthrodesis cannot be eliminated, reconstruction of the ligament will delay and may prevent the onset arthritis, allowing the patient to maintain mobility of the ankle joint. The anatomy, surgery, and risks and benefits are discussed.

And health plans can't be caught flat-footed. They need to keep pace with the introduction of new treatments and be ready with strategies that address patient needs and manage costs. Using objective clinical data to guide dosing and working to redirect care to a patient's home is a place to start.
