  2. Lower-limb walking pattern - Wikipedia

    en.wikipedia.org/wiki/Lower-limb_walking_pattern

    Between 30-50% of the gait cycle, the hip flexor muscles are eccentrically acting as the hip continues to extend, until reaching maximal extension at approximately 10-15 degrees past neutral. [3] This max extension takes place right before toe off. The hip flexors then concentrically act to initiate hip flexion for swing phase. Overall ...

    • Iliopsoas: The powerhouse of hip flexion, a combination of two muscles — the iliacus and psoas — which, together, connect your pelvis, lumbar spine (low back) and femur (upper leg bone).

  4. GALS screen - Wikipedia

    en.wikipedia.org/wiki/GALS_screen

    Place your hand over the knee and then the hip joints feeling for crepitus as the patient moves these joints. Now test internal rotation of the hip with the knee joint flexed to 90 degrees (moving the foot laterally with the knee flexed causes internal rotation of the hip joint - early OA causes pain and limitation of this movement).

  5. Femoroacetabular impingement - Wikipedia

    en.wikipedia.org/wiki/Femoroacetabular_impingement

    Physical exam should also involve assessing passive internal rotation of the hip during flexion, as range of motion is reduced in proportion to the size of a cam lesion. [10] Flexing the hip to 90 degrees, adducting, and internally rotating the hip, known as the FADDIR test, should also be performed. [10] It is positive when it causes pain.

  6. Sacroiliac joint dysfunction - Wikipedia

    Then, downward pressure is applied to the medial knee stressing both the hip and sacroiliac joint. [1] [2] [4] Thigh Thrust - This test applies anteroposterior shear stress on the SI joint. The patient lies supine with one hip flexed to 90 degrees. The examiner stands on the same side as the flexed leg.

  7. Ober test - Wikipedia

    en.wikipedia.org/wiki/Ober_test

    During the test, the patient lies on his/her side with the unaffected leg on the bottom with their shoulder and pelvis in line. The lower hip and knee can be in a flexed position to take out any lordosis of the lumbar spine. [1] No studies support the validity of the Ober test for measuring iliotibial band tightness. [2]

  8. Piriformis muscle - Wikipedia

    en.wikipedia.org/wiki/Piriformis_muscle

    The piriformis laterally rotates the femur with hip extension and abducts the femur with hip flexion. [2] Abduction of the flexed thigh is important in the action of walking because it shifts the body weight to the opposite side of the foot being lifted, which prevents falling.

  9. Pectineus muscle - Wikipedia

    en.wikipedia.org/wiki/Pectineus_muscle

    The pectineus muscle is the most anterior adductor of the hip. The muscle's primary action is hip flexion; it also produces adduction and external rotation of the hip. It can be classified in the medial compartment of thigh [2] (when the function is emphasized) or the anterior compartment of thigh (when the nerve is emphasized). [3]
