The tensor fasciae latae works in synergy with the gluteus medius and gluteus minimus muscles to abduct and medially rotate the femur. The TFL is a hip abductor muscle. To stretch the tensor fasciae latae, the knee may be brought medially across the body (adducted).
The rate of deformation tensor gives the rate of stretching of line elements while the spin tensor indicates the rate of rotation or vorticity of the motion. The material time derivative of the inverse of the deformation gradient (keeping the reference configuration fixed) is often required in analyses that involve finite strains.
Iliotibial band syndrome is one of the leading causes of lateral knee pain in runners. The iliotibial band is a thick band of fascia composing the tendon of the tensor fasciae latae muscle. It is located on the lateral aspect of the knee, extending from the outside of the pelvis, over the hip and knee, and inserting just below the knee.
Thomas test. To rule out hip flexion contracture & psoas syndrome. The Thomas test is a physical examination test, named after the Welsh orthopaedic surgeon, Hugh Owen Thomas (1834–1891), to rule out hip flexion contracture (fixed partial flexion of the hip) and psoas syndrome (injury to the psoas muscle). Illustration of the Thomas test.
The (infinitesimal) strain tensor (symbol ) is defined in the International System of Quantities (ISQ), more specifically in ISO 80000-4 (Mechanics), as a "tensor quantity representing the deformation of matter caused by stress. Strain tensor is symmetric and has three linear strain and three shear strain (Cartesian) components." [ 6]
Snapping hip syndrome, also referred to as dancer's hip, is a medical condition characterized by a snapping sensation felt when the hip is flexed and extended. This may be accompanied by a snapping or popping noise and pain or discomfort. Pain often decreases with rest and diminished activity. Snapping hip syndrome is commonly classified by the ...
The fascia lata is an investment for the whole of the thigh, but varies in thickness in different parts. It is thicker in the upper and lateral part of the thigh, where it receives a fibrous expansion from the gluteus maximus, and where the tensor fasciae latae is inserted between its layers; it is very thin behind and at the upper and medial part, where it covers the adductor muscles, and ...
Invariants of tensors. In mathematics, in the fields of multilinear algebra and representation theory, the principal invariants of the second rank tensor are the coefficients of the characteristic polynomial [ 1] where is the identity operator and are the roots of the polynomial and the eigenvalues of . More broadly,any scalar-valued function ...
