background anterior cruciate ligament (acl) injury is the most common sports injury in both athletes and nonathletes; it can cause disability if not treated correctly. in cases with minor injuries, conservative treatments suffice. but, in cases with acl tear, surgery by different methods and autografts are indicated. the most prevalent method for acl reconstruction is the use of hamstring tendo...

background: posttraumatic and/or postsurgical knee stiff ness is one of the orthopedic complications which is difficult to be treated and can affect individual’s life negatively. the aim of this study is to investigate the results of quadricepsplasty in patients with knee stiff ness resulted from femoral fracture. materials and methods: this is a cross-sectional study on all patients with femor...

Cosmic flexion, like cosmic shear, is a correlation function whose signal originates from the large-scale structure of universe. Building on observational success along with unprecedented quality cosmological datasets, time ripe to explore practical constraints flexion. Unlike which has broad window for power, flexion only measurable small scales and therefore can uniquely place small-scale mat...

Abstract:   Objectives: Flexion contractures of the proximal interphalangeal joint are of the most common complication result from surgical procedures and traumatic events.  Orthotic interventions for treatment of contractures may include serial splinting, serial casting, dynamic and/ or static progressive orthoses, or a combination of these orthoses.  This study aimed to determine the effect ...

Purpose: In approaching full trunk flexion (75%-80% of full flexion), myoelectric activity of lumbar erector spinae muscles is reduced or silenced; this response is known as flexion-relaxation phenomenon (FRP). FRP is a shift in load sharing and spinal stabilization from active structures (erector spinae muscles) to passive ligamentous and articular structures. Static lumbar flexi...

conclusions an increased lumbar lordosis during the prone knee-flexion test is due to instability in a lumbar spine region. results results demonstrated that there was a statistically significant difference in lumbar lordosis in prone position and after performing the prone knee-flexion test among healthy subjects (p < 0.0001). patients and methods this quasi-experimental study with repeated me...
