conclusions our results indicate that changes in muscle thickness and echo intensity are induced by different inward pressures of the transducer during us. when using a technique that involves a handheld transducer, the examiner should attempt to maintain consistent inward pressure of the transducer during us, to quantify the minimal change of the rf mass and composition. results muscle thickne...

BACKGROUND Rectus femoris tendon transfer is performed in patients with cerebral palsy to improve knee flexion during walking. This procedure involves detachment of the muscle from its insertion into the quadriceps tendon and reattachment to one of the knee flexor muscles. The purpose of the present study was to evaluate the muscle-tendon geometry and to assess the formation of scar tissue betw...

Introduction Rectus femoris transfer surgery is performed to improve knee flexion in persons with cerebral palsy who walk with a stiff-knee gait (Gage et al., 1987; Perry, 1987). In this surgery, the rectus femoris muscle is separated from the quadriceps tendon, tunneled through the subcutaneous tissue on the medial aspect of the thigh and sutured to one of the knee flexors – such as sartorius ...

Rectus femoris transfer surgery is performed to convert the rectus femoris muscle from a knee extensor to a knee flexor. In this surgery, the distal tendon of the rectus femoris is detached from the patella and reattached to one of the knee flexor tendons. The outcomes of this procedure are variable, and it is not known if the surgery successfully converts the muscle to a knee flexor. We measur...

Stiff-knee gait is characterized by diminished and delayed knee flexion during swing. Rectus femoris transfer surgery, a common treatment for stiff-knee gait, is often recommended when a patient exhibits prolonged activity of the rectus femoris muscle during swing. Treatment outcomes are inconsistent, in part, due to limited understanding of the biomechanical factors contributing to stiff-knee ...

[Purpose] The purpose of this study was to analyze muscle activation during hip flexion in the supine position to examine the activation characteristics of the rectus abdominis and rectus femoris. [Subjects] The subjects of this study were 20 healthy adults (10 males and 10 females). [Methods] Muscle activities of the rectus abdominis and rectus femoris while raising the leg from 0°-60° were me...

background: gait disorder is a common motor complication after stroke. studies have revealed that conventional physiotherapy cannot manage this disorder efficiently; therefore, more studies regarding efficient treatment protocols are crucial. the purpose of this study was to investigate the effect of compelled weight-bearing approach on muscle activation patterns during walking in individuals w...

Background & objectives: Benches play a basic role in students sitting in the correct posture for a long period. The purpose of this study was to investigate the effect of ergonomics of common school benches on the electrical activity of selected muscles of healthy female students or with lumbar lordosis. Methods: For this purpose, 24 students with an average age of 10.26±1.78 years were selec...
