The cause of mobility disorders

              Human beings try to realize personally and socially. In the course of these activities which requiring physical activity in onto-genesis can lead to restrict mobility of the lower limbs or even dysfunction. In cases of mechanical fracture, injury, contusions, sprains or changes in or around the joints can manifest as a lacks of movement. To restriction of the movement may also occur because of the neurological changes in such diseases such as: stroke, spinal cord injury, peripheral nerve injury, multiple sclerosis, Parkinson's disease.

              Standing to long in the same position, when person lies in the bed it promotes limitations of mobility; could appear sores and contractures of muscle.

Osteoarthrosis (OA) which is the most common in older people, are the results of the interaction on mechanical, cellular and biochemical level. Leads to disruption of the regeneration processes of articular cartilage and also subchondral bone layer. These results in degenerative changes of joints and lead to limitations of the range of motion movement. The most common restrictions include hip and knee joints, making difficult to move for old people.

Predisposing factors for OA is the age above 55 years, the disease is more common in women. Excess of weight leads to overload of the joints and rapid attrition of the joints surface. Disorders, acute injuries, chronic disorders, changes because of heavy lifting, extreme sports are the most common elements for affecting functions of the joints.

Mobility limitations can lead to inflammation disorders, aseptic necrosis, exfoliation of the femur, Paget's disease, neuropathies, iatrogenic changes, congenital diseases and genetics.

With age comes a weakening ligament of joints, as well a changes in articular surfaces. Insufficient amount of movement, poor diet and over lifting are typical factors which reduce mobility of the joints in elderly people.
