TY - CHAP M1 - Book, Section TI - The Hip A1 - KISNER, CAROLYN A1 - BORSTAD, JOHN A2 - Kisner, Carolyn A2 - Borstad, John A2 - Colby, Lynn Allen PY - 2023 T2 - Therapeutic Exercise: Foundations and Techniques, 8e AB - The hip is similar to the glenohumeral joint in that it is a triaxial joint, functions in all three planes, and is the proximal link to its extremity. In contrast to the highly mobile shoulder, however, the hip is a stable joint that is adapted for upright standing and weight-bearing activities. At the same time, at least 120° of hip flexion and 20° each of abduction and external rotation are necessary to carry out activities of daily living (ADLs) in what is considered a “normal” manner.140 Because forces from the lower extremities are transmitted upward through the hips to the pelvis and trunk during gait and other lower extremity activities, and because the hips support the weight of the head, trunk, and upper extremities, the health of the hip joint is vital for most functional activities.
