The hip Flashcards
what is the function of the hip
- stability and strength
- efficient weight bearing in resisting stance
- single leg stance
- high forces during movement
- mobility
- range of movement for walking/running/jumping/climbing
- allow for multidirectional movement
- adaptable to environment
how does the structure of the hip match the function
- ball and socket joint
- multiaxial movement
- deep socket and labrum
- angle of neck of femur
- allows muscle leverage
- skeletal biomechanics for SLS
what movements are available at the hip
- flexion/extension - sagittal plane - sagittal axis
- abduction/adduction - frontal plane - frontal axis
- external/internal rotation - transverse plane - transverse axis
how to the hips stay stable and strong
- trabeculae system
- compression
- tension
- ligaments
- extension
- medial rotation
- abduction
