We often see painful ankle joint destruction with painful hindfoot valgus deformity in rheumatoid arthritis. Our policy in such cases has been to first correct the hindfoot deformity in the subtalar joint with fusion, but then ankle joint pain has been observed. Two women with rheumatoid arthritis underwent correction and fusion surgery for hindfoot valgus deformity. They had been using wheelch...

introduction: sensory-motor control and in general gaining balance will be impaired after an ankle injury and in fatigue situations. the aim of this research was to study the effect of exercise-based fatigue on static and dynamic balance in mountaineering athletes who were successful in returning to a suitable level of physical activity after an ankle sprain injury. materials and methods: 25 ac...

methods thirty healthy female volunteers aged between 18 and 30 years were treated by a 15-minute cryotherapy (6 ± 1°c). the subject's skin temperature over antromedial aspect of dominant ankle was measured by the mayomed device before, immediate and 15 minutes after water immersion. ankle jps was tested trough the pedal goniometer at 3 stages similar to the skin temperature. anova (α = 0.05) w...

background : biomechanical factors are known to be important in knee osteoarthritis (oa) development and progression. this study was designed to determine changes of hamstrings muscle activation, knee adduction moment and ankle rotation angle in two knee osteoarthritis (mild and moderate) and a healthy control group.   methods: 16 females (10 with mild and 6 with moderate medial knee osteoarthr...

Ankle arthroscopy carries a lower risk of vascular complications when standard anterolateral and anteromedial portals are used. However, the thickness of the fat pad at the anterior ankle affords little protection for the thin-walled anterior tibial artery, rendering it susceptible to indirect damage during procedures performed on the anterior ankle joint. To our knowledge, only 11 cases of pse...

The invention concerns a method to remotely measure the nodes’ quartz frequencies within a distributed system based on FlexRay. The proposed approach uses the clock correction mechanism and more especially the integrated damping factor, which slightly shifts the node’s internal clock correction term and its resulting time base. The invention was made by researchers of the Vienna University of T...

[1] Flexural modeling of Ithaca Chasma on Tethys suggests that the elastic thickness and the surface heat flux were 5–7 km and 18–30 mW/m respectively, when the feature formed ( 4 Gyr B.P.). Tidal heating is a plausible heat source, suggesting that Tethys’ eccentricity was higher in the past. Depending on Tethys’ internal structure, eccentricities in the range 0.001 to 0.02 are sufficient to ha...

A family of Boussinesq systems was proposed by J. L. Bona, M. Chen and J.-C. Saut to describe the two-way propagation of small amplitude gravity waves on the surface of water in a canal. Our work considers a class of these Boussinesq systems which couples two Benjamin-Bona-Mahony type equations posed on a bounded interval. We study the stabilization of the resulting system when a localized damp...

normal axial alignment restoration in lower extremities is crucial for surgeons performing reconstructive surgeries. since reference normal values of axial alignment are affected by age, sex, and ethical issues, we tried to scrutinize these parameters in iranian adults and compare them with normal values in literatures. through a cross-sectional design, standing axial alignment views of lower e...
