OBJECTIVE To evaluate the effects of wearing a functional knee brace and muscle fatigue on hamstring reflex time in subjects with anterior cruciate ligament (ACL) deficiency. DESIGN Repeated-measures clinical trial. SETTING Outpatient physical therapy department. PARTICIPANTS Sixteen subjects with ACL deficiency. INTERVENTION Subjects tested with and without a functional knee brace befo...

The use of structural steel profiles as an external shear bracing is one the most preferable simple, time saving and cost-efficient strengthening method for inadequate existing reinforced concrete (RC) structure against earthquake lateral loads in comparison to other interrupting, irritating destructive traditional plane methods which need evacuation houses. With this method, inhabitants buildi...

the present article seek to investigate the function of elliptical steel damper function in steel frames seismic resisting. the elliptical damper is a kind of earthquake energy dissipater in structure which acts based on the steel yielding feature. thus, this damper in frame lateral displacement mechanism is expected to have a satisfying hysteretic behavior in terms of energy absorption is on a...

Background: In cerebral palsy, importance must be given on effective and efficient walking. 30 subjects; 16 males 14 females (mean age 6.5 year) of spastic palsy with knee hyperextension ankle equines were included in this study fitted bilateral moldedhinged SKAFO pair shoes.Methods: Observational gait analysis by video recording was performed parameters 10 m walk test angle at mid stance using...

This paper examines the condition of anterior knee pain known as patellofemoral pain syndrome. It describes the functional anatomy and biomechanics of the knee including normal movement, and factors which may destabilize the knee, and predispose it to injury. The controversial ‘‘Q’’ angle is discussed, as is its relationship to patellofemoral pain. The importance of balanced musculature to the ...

Steel braced frames are commonly used in steel structures to control and improve the seismic performance of under severe lateral forces such as an earthquake. So, providing better formability would help designers achieve their desire level. This study is focused on utilizing curved dampers ductile frame instead using knee elements provide energy dissipation, strength, elastic stiffness during c...

In this paper, a real-time monitoring system—including vibration acceleration sensors, temperature and static dynamic strain sensors—is used to monitor the safety status of steel assembly bracing in practical project. It uses 5G wireless networking technology transmit data cloud server for early warning abnormal changes development trends. Real-time obtained construction site are as inputs fini...

Non-ductile reinforced concrete frames are commonly found in older buildings many parts of the world. These structures designed for gravity loads, have limited lateral strength and ductility, prone to excessive one-way movement soft-story mechanism. This paper focuses on retrofit an existing frame, using steel X-braces by direct internal connection method. The main purpose is analytical study g...

An increasing number of reconstructions of the anterior cruciate ligament (ACL) are performed every year, due to both the increasing occurrence of sport related injuries and the development of diagnostic and surgical techniques. The most used surgical procedure for the torn ACL reconstruction is the use of autogenous material, most often the patellar and semitendinosus tendons. Magnetic resonan...
