Task-Dependent Inhomogeneous Muscle Activities within the Bi-Articular Human Rectus Femoris Muscle
The motor nerve of the bi-articular rectus femoris muscle is generally split from the femoral nerve trunk into two sub-branches just before it reaches the distal and proximal regions of the muscle. In this study, we examined whether the regional difference in muscle activities exists within the human rectus femoris muscle during maximal voluntary isometric contractions of knee extension and hip...
متن کاملRectus Femoris Muscle Volume Estimate by Ultrasonography
Imaging techniques allow in vivo measurement of parameters studied in vitro or ex vivo and thus greater reliability regarding muscle mechanics in real situations. Some muscle architecture parameters are directly related to force production, mainly the volume. It can be estimated by the sum of segmental volumes (product of the sum of crosssectional areas and the distance between them) of sequent...
متن کاملIsolated contracture of the rectus femoris muscle.
A girl of twenty had complained of pain in the right leg when walking, early fatigue and a limp, since breaking the right ankle three years before. She had not had any other accident or any illness. The knee could not be flexed without flexing the hip (Fig. 1). Conversely the hip could not be extended without extending the knee; indeed, extreme extension of the hipwas impossible even with the k...
متن کاملUnilateral short rectus femoris muscle belly
Introduction Rectus femoris is a spindle shaped muscle forming part of the quadriceps muscle group in the anterior compartment of the thigh. Traditionally, it is described as having two heads which arise as a straight tendon from the anterior inferior iliac spine and a reflected tendon from the ilium just above the acetabulum. Recent studies have shown that the anatomy of the muscle is more com...
متن کاملImportance 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 ...
