in the current study the effect of casimir force and squeezed film damping on the pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems is investigated separately. linear elastic membrane theory is used to model the static and dynamic behavior of system for strip, annular and disk geometries. squeezed film damping effect is modeled using...

Purpose: Many research studies reported balance disorder as one of the most important consequences of Functional Ankle Instability. However, the Balance Recovery Strategy, which its deficiency can cause poor balance or secondary damages, has not been investigated in previous studies yet. The purpose of this article is to study the Balance Recovery Strategy in athletes with Functional Ankle Inst...

background: ankle fractures, especially those resulting from external rotation mechanisms are associated with injury to the distal tibiofibular syndesmosis. some authors have recommended performing ct scanning after open ankle surgery to evaluate the reduction of syndesmosis. in this current study, we aimed to investigate the sensitivity of plain radiography in diagnosing syndesmosis malreducti...

introduction :  an ankle sprain is the most common injuries which due to damage to the proprioceptive receptors and decrease stability, the risk of re- injury is high. the aim of this study was to investigate the effect of star excursion balance training on ankle sprain rehabilitation. materials and methods: sixteen non-professional athletes with history of unilateral ankle sprain which reporte...

we present a case of epitheloid sarcoma that was referred with a 2×3cm ulcerated lesion on the right ankle and edema of the lower leg. foot drop of the right side was present that had caused walking difficulty. after a few months, he developed several sporthricoidal nodular lesions on the medial aspect of right thigh, inguinal lymphadenopathy, weight loss, anorexia and respiratory symptoms. che...

To facilitate the damping matching of dampers for vehicle passive suspensions, this paper proposes an analytical matching method of the optimal piecewise linear damping characteristics curve. Based on the vehicle vibration model, taking the suspension dynamic deflection as the constraint, by the vibration acceleration and the wheel dynamic load, an objective function about the relative damping ...

 Abstract Background: Several studies have examined the reflex response of ankle musculature to sudden inversion in noninjured and injured subjects. To date, there have been no studies to determine the effect of versatile degrees & conditions of perturbation on the ankle musculature latency. The purpose of this study was to measure and determine whether there was a difference in ankle musculatu...

Objectives: The results of a few studies about the effects of ankle brace on muscles function during the performance of different tasks are contradictory. Moreover, the effect of brace on the co-contraction of ankle muscles is undiscovered. Therefore, the present study investigated the effect of brace usage on the ankle muscles activity and co-contraction during single-leg landing. Methods: Fi...
