Importance of preswing rectus femoris activity in stiff-knee gait.
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 ...
متن کاملEffect of the rectus femoris motor branch block on post-stroke stiff-legged gait.
Six hemiparetic stroke patients presenting with a stiff-legged gait underwent a motor branch block of rectus femoris (RF). A gait analysis, including synchronous kinematic, dynamic, energetic recordings was performed before and after motor branch block of RF. The electrical activity of RF, Vastus Medialis, Vastus Lateralis, Vastus Intermedius was also recorded. Before nerve block, the sagittal ...
متن کاملMechanism of Improved Knee Flexion After Rectus Femoris Transfer Surgery
Simulation results suggest that the primary mechanism for improvement in knee flexion after surgery is reduction of the muscle’s knee extension moment, rather than conversion to a knee flexion moment. Scarred transfer simulations resulted in an average peak knee flexion improvement (14° ± 5°) comparable to the average increase in knee flexion range of motion (13° ± 11°) in the subjects’ postope...
متن کاملMechanisms of improved knee flexion after rectus femoris transfer surgery.
Rectus femoris transfer is frequently performed to treat stiff-knee gait in subjects with cerebral palsy. In this surgery, the distal tendon is released from the patella and re-attached to one of several sites, such as the sartorius or the iliotibial band. Surgical outcomes vary, and the mechanisms by which the surgery improves knee motion are unclear. The purpose of this study was to clarify t...
متن کاملRectus femoris to gracilis muscle transfer with fractional lengthening of the vastus muscles: a treatment for adults with stiff knee gait.
BACKGROUND Stiff knee gait, which may be seen in patients with upper motor neuron injury, describes a gait pattern with a relative loss of sagittal knee motion. It interferes with foot clearance during swing, often leading to inefficient compensatory mechanisms and ambulatory dysfunction. Distal rectus femoris muscle transfers and fractional lengthening of the vastus muscles have been performed...
