TY - CHAP M1 - Book, Section TI - The Hip A1 - Kisner, Carolyn A1 - Colby, Lynn Allen Y1 - 2012 N1 - T2 - Therapeutic Exercise: Foundations and Techniques, 6e AB - The hip is often compared with the shoulder in that it is a triaxial joint, able to function in all three planes, and also the proximal link to its extremity. In contrast to the shoulder, which is designed for mobility, the hip is a stable joint, constructed for weight bearing. To carry out activities of daily living (ADL) in what is considered a "normal" manner, however, at least 120° of hip flexion and 20° each of abduction and external rotation are necessary.110 Forces from the lower extremities are transmitted upward through the hips to the pelvis and trunk during gait and other lower extremity activities. Conversely, the hips support the weight of the head, trunk, and upper extremities, and therefore, the function of the lumbopelvic and hip muscles influences the mechanics and function of the entire lower extremity.
