It is relatively common among children and affects more females than males. Current thinking suggests four causative factors: The shape of the ends of the bones—Some joints normally have a large range of movement, such as the shoulder and hip. Both are ball-and-socket joints. If a shallow rather than a deep socket is inherited, a relatively ...
Joint instability and soft tissue injuries: Dislocations, subluxations, or damage to muscles, ligaments, tendons, synovium, or cartilage as a result of excessive joint movement. Chronic pain : Recurrent joint pain that can develop into hyperalgesia , with a higher rate of small fiber neuropathy in some individuals.
The list below describes such skeletal movements as normally are possible in particular joints of the human body. Other animals have different degrees of movement at their respective joints; this is because of differences in positions of muscles and because structures peculiar to the bodies of humans and other species block motions unsuited to ...
There are many mechanisms in the body that are suggested to control this movement, e.g. a spring action in muscles, higher control from the nervous system or core muscles. Although the posture is not dangerous in itself, there are pathologies associated with prolonged intervals of unrelieved standing.
A multiaxial joint, such as the hip joint, allows for three types of movement: anterior-posterior, medial-lateral, and rotational. A multiaxial joint (polyaxial joint or triaxial joint) is a synovial joint that allows for several directions of movement. [9] In the human body, the shoulder and hip joints are multiaxial joints.

The sole reliance on the hip joint to control the entire prosthetic limb makes fine-tuning foot placement difficult. Lowering the knee joint height was found to effectively increase the hip joint's lever arm, thereby increasing precision control of the hip joint to improve gait symmetry and increase running velocity by 26% on average.

Children are assessed for the risk of hip displacement using radiography. [75] [90] Music therapy has been used in CP to motivate or relax children, or used as auditory feedback. Playing percussion instruments has been used as part of groupwork in therapy. Piano lessons may be beneficial in CP rehabilitation, however more research is needed. [91]
