People Getting Degenerative Changes In Early Ages, Changes in posture and gait (walking pattern) are common with aging. Changes in the skin as well as hair .
The skeleton provides support and structure to the body. Joints are the areas where bones come together. They allow the skeleton to be flexible for movement. In a joint, bones do not directly contact each other. Instead, they are cushioned by cartilage in the joint, synovial membranes around the joint and by fluid.
Muscles provide the force and strength to move the body. Coordination is directed by the brain, but is affected by changes in the muscles and joints. Changes in the muscles, joints, and bones affect the posture and walk, and lead to weakness and slowed movement.
AGING CHANGES (Degenerative Changes In Early Ages)
People lose bone mass or density as they age, especially women after menopause. The bones lose calcium and other minerals.
The spine is made up of bones called vertebrae. Between each bone is a gel-like cushion (called a disk). With aging, the middle of the body (trunk) becomes shorter as the disks gradually lose fluid and become thinner.
Infact, Vertebrae also lose some of their mineral content, making each bone thinner. The spinal column becomes curved and compressed (packed together). Bone spurs caused by aging and overall use of the spine may also form on the vertebrae.
The foot arches become less pronounced, contributing to a slight loss of height.
The long bones of the arms and legs are more brittle because of mineral loss, but they do not change length. This makes the arms and legs look longer when compared with the shortened trunk.
Lean body mass decreases. This decrease is partly caused by a loss of muscle tissue (atrophy). The speed and amount of muscle changes seem to be caused by genes. Muscle changes often begin in the 20s in men and in the 40s in women.
Lipofuscin (an age-related pigment) and fat are deposited in muscle tissue. The muscle fibers shrink. Muscle tissue is replaced more slowly. Lost muscle tissue may be replaced with a tough fibrous tissue. This is most noticeable in the hands, which may look thin and bony.
Muscles are less toned and less able to contract because of changes in the muscle tissue and normal aging changes in the nervous system. Muscles may become rigid with age and may lose tone, even with regular exercise.
EFFECT OF CHANGES (Degenerative Changes In Early Ages)
Bones become more brittle and may break more easily. Overall height decreases, mainly because the trunk and spine shorten.
Breakdown of the joints may lead to inflammation, pain, stiffness, and deformity. Joint changes affect almost all older people. These changes range from minor stiffness to severe arthritis.
The posture may become more stooped (bent). The knees and hips may become more flexed. The neck may tilt, and the shoulders may narrow while the pelvis becomes wider.
Movement slows and may become limited. The walking pattern (gait) becomes slower and shorter. Walking may become unsteady, and there is less arm swinging. Older people get tired more easily and have less energy.
Strength and endurance change. Loss of muscle mass reduces strength.
COMMON PROBLEMS (Degenerative Changes In Early Ages)
Muscle weakness contributes to fatigue, weakness, and reduced activity tolerance. Joint problems ranging from mild stiffness to debilitating arthritis (osteoarthritis) are very common.
Some older people have reduced reflexes. This is most often caused by changes in the muscles and tendons, rather than changes in the nerves. Decreased knee jerk or ankle jerk reflexes can occur. Some changes, such as a positive Babinski reflex, are not a normal part of aging.
Involuntary movements (muscle tremors and fine movements called fasciculations) are more common in the older people. Older people who are not active may have weakness or abnormal sensations (paresthesias).
People who are unable to move on their own, or who do not stretch their muscles with exercise, may get muscle contractures.
PREVENTION (People Getting Degenerative Changes In Early Ages)
Exercise is one of the best ways to slow or prevent problems with the muscles, joints, and bones. A moderate exercise program can help you maintain strength, balance, and flexibility. Exercise helps the bones stay strong.
Before starting a new exercise program talk to your health care provider.
It is important to eat a well-balanced diet with plenty of calcium. Women need to be particularly careful to get enough calcium and vitamin D as they age. Postmenopausal women and men over age 70 should take in 1,200 mg of calcium per day. Women and men over age 70 should get 800 international units (IU) of vitamin D daily. If you have osteoporosis, talk to your provider about prescription treatments.
