Background: Deficits in upper body movement have received little attention during gait in cerebral palsy (CP) children with crouch gait pattern (CGP).Objective: Purpose of this research is to describe the correlation of trunk movement with the excessive knee flexion and ankle kinematic in CP children with CGP.Methods: Gait analysis data from 57 limbs of diplegic CP children with CGP and 26 limb...

The diminished knee flexion associated with stiff-knee gait, a movement abnormality commonly observed in persons with cerebral palsy, is thought to be caused by an over-active rectus femoris muscle producing an excessive knee extension moment during the swing phase of gait. As a result, treatment for stiff-knee gait is aimed at altering swing-phase muscle function. Unfortunately, this treatment...

Stiff-knee gait is a movement abnormality in which knee flexion during swing phase is significantly diminished. This study investigates the relationships between knee flexion velocity at toe-off, joint moments during swing phase and double support, and improvements in stiff-knee gait following rectus femoris transfer surgery in subjects with cerebral palsy. Forty subjects who underwent a rectus...

BACKGROUND Excessive hip flexion in gait is thought to be associated with hip flexion contracture, but has also been associated with excessive anterior pelvic tilt, knee flexion, internal hip rotation, and muscular factors. The purpose of this study was to examine the contributors to excessive hip flexion during gait in children with cerebral palsy, with and without hip flexion contractures. ...

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...

Crouch gait, a common walking pattern in individuals with cerebral palsy, is characterized by excessive flexion of the hip and knee. Many subjects with crouch gait experience knee pain, perhaps because of elevated muscle forces and joint loading. The goal of this study was to examine how muscle forces and compressive tibiofemoral force change with the increasing knee flexion associated with cro...

Ankle-Foot Orthoses (AFOs) are commonly prescribed to promote gait in children with cerebral palsy (CP). The AFO prescription process is however largely dependent on clinical experience, resulting in confusing results regarding treatment efficacy. To maximize efficacy, the AFO's mechanical properties should be tuned to the patient's underlying impairments. This study aimed to investigate whethe...

Crouch gait, a common condition among children with cerebral palsy, decreases walking efficiency due to the increased knee and hip flexion during the stance phase of gait [1]. Excessive knee flexion during walking deteriorates joints and leads to chronic knee pain [2], and if untreated, these symptoms can worsen over time [3]. Several factors have been linked with crouch gait, including muscle ...

INTRODUCTION Rigid Ankle-Foot Orthoses (AFOs) are commonly prescribed to counteract excessive knee flexion during the stance phase of gait in children with cerebral palsy (CP). While rigid AFOs may normalize knee kinematics and kinetics effectively, it has the disadvantage of impeding push-off power. A spring-like AFO may enhance push-off power, which may come at the cost of reducing the knee f...

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...
