objectives: skeletal-muscular disorders affect the biomechanics of the human body, especially the lower extremity, with a negative effect on the biomechanics of exercise. the main aim of this study was to evaluate the effect of fatigue on the kinematic variables of knee joints during countermovement jumps in female students of physical education with valgus knee deformity.  methods: fifteen sub...

Despite general agreement on the effects of knee valgus and internal tibial rotation on anterior cruciate ligament (ACL) loading, compelling debate persists on the interrelationship between these rotations and how they contribute to the multi-planar ACL injury mechanism. This study investigates coupling between knee valgus and internal tibial rotation and their effects on ACL strain as a quanti...

Valgus moments on the knee joint during single-leg landing have been suggested as a risk factor for anterior cruciate ligament (ACL) injury. The purpose of this study was to test the influence of isolated valgus moment on ACL strain during single-leg landing. Physiologic levels of valgus moments from an in vivo study of single-leg landing were applied to a three-dimensional dynamic knee model, ...

BACKGROUND Knee valgus load during sports movement is viewed as an important predictor of non-contact anterior cruciate ligament injury risk, particularly in females. Formulating movement strategies that can reduce valgus loading during these movements therefore appears pertinent to reducing anterior cruciate ligament injury rates. With this in mind, the current study examined the relationship ...

BACKGROUND Studies have shown that various biomechanical factors affect valgus extension overload during baseball pitching; yet, their relationships are not clearly defined, and factors such as trunk rotation and arm slot have not been investigated. HYPOTHESIS The onset of trunk rotation, with other biomechanical variables that define sequential body motion, will significantly predict elbow v...

background: there are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. in the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. methods: forty patients with valgus knee malalignment were randomly assigned to two equal numb...

Twenty feet were tested by radiological examination for correction of the hallux valgus. We used a conventional hallux valgus rigid night brace and a newly developed dynamic orthosis (Hallufix). The patients had a light to moderate hallux valgus with a mean angle of 28,8 degree. The results show statistically significant correction of the hallux valgus angle in both orthosis, whereas the new dy...

hallux valgus or the lateral deviation of the great toe is a complex disease. if it is not treated, it will cause the deviation of other toes. hallux valgus is three times more common in females and may cause uncomfortable deformity of the foot, problems in putting on unsuitable and narrow toe box shoes, and pain on the medial side of the first metatarsophalangeal joint; therefore, patients see...

BACKGROUND Most previous studies on hallux valgus focused on the possible relationship between this deformity and muscles and/or ligaments in the foot and lower leg. Very little is known about the relationship between hallux valgus and alignment of the proximal joints. The aims of the present study were to determine the extent to which lower extremity alignment characteristics of the hip, knee,...
