Document Summary
Okc: femur moves on the pelvis (convex moving on a concave): joint mobilization: [movement] (available degrees of movement): how to mobilize to increase rom. There are three; all are very thick and strong: Rim of cartilage that surrounds the hip joint. Flexion: psoas, iliacus, rectus femoris, sartorius, tfl. Abduction: gluteus medius, gluteus minimus, tfl. Adduction: adductor brevis, longus, magnus, gracilis. Er: piriformis, gluteus maximus, gemelli, gluteus medius, obturator internus. Femoral nerve: injury/entrapment with pelvic or femoral fractures. Rom: 30 during flexion at swing, initial contact, loading response, 10 during extension at terminal stance. Muscle weakness in hip can lead to profound changes in gait; in turn, knee/ankle impairments might influence hip. If weak, feet will drag or have small step because they cannot be lifted. If contracted: decreased step length due to lack of a terminal stance. Hip extensors: controls flexion movement in loading response: weakness: posterior lurch. Hip abductors: stabilizes hip in mid stance: weakness: trendelenburg gait.
