Once the pelvis begins to tilt anteriorly, stop the passive range of motion, hold the affected thigh in this position, and measure the angle between the affected thigh and table to reveal the fixed flexion deformity of the hip. It is important to control the pelvic tilt to ensure that the Thomas test is valid for evaluating peak hip extension ...
Kaltenborn test or Hip Lag Sign for hip abductor function. To perform the Kaltenborn test, the patient has to lie in a lateral, neutral position with the affected leg being on top. The examiner then positions one arm under this leg to have good hold and control over the relaxed extremity, whereas the other hand stabilizes the pelvis.
This machine has been used to strengthen not only the erector spinae muscle, but also gluteus maximus and part of hamstring muscles (biceps femoris). When back extension is attempted with this machine, the range of motion at hip is found to be relatively more, while the accompanying stresses at hip and back have been found not to relatively less.
The psoas sign, also known as Cope's sign (or Cope's psoas test [1]) or Obraztsova's sign, [2] is a medical sign that indicates irritation to the iliopsoas group of hip flexors in the abdomen, and consequently indicates that the inflamed appendix is retrocaecal in orientation (as the iliopsoas muscle is retroperitoneal).
The gluteal muscles include the gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae latae.They cover the lateral surface of the ilium.The gluteus maximus, which forms most of the muscle of the buttocks, originates primarily on the ilium and sacrum and inserts on the gluteal tuberosity of the femur as well as the iliotibial tract, a tract of strong fibrous tissue that runs ...

The gluteus maximus straightens the leg at the hip; when the leg is flexed at the hip, the gluteus maximus extends it to bring the leg into a straight line with the body. [3] The anus also aligns when the leg is flexed at the hip, making the muscle tighten and the pelvis tilt forward.
The lateral rotator group is a group of six small muscles of the hip which all externally (laterally) rotate the femur in the hip joint.It consists of the following muscles: piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and the obturator externus.
