Common problems
Osteoporosis is a common problem, especially for older women. Broken bones occur more readily, and compression fractures of the vertebrae can cause pain and reduce mobility.
Muscle weakness contributes to fatigue, weakness, and reduced activity tolerance. Joint problems are extremely common. This may be anything from mild stiffness to debilitating arthritis (see osteoarthritis).
Injury risk is greater because of falls related to gait changes, instability, and loss of balance.
Some elderly 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 is not unexpected.
Some changes, such as a positive Babinski's reflex, are always considered abnormal.
Involuntary movements (muscle tremors and fine movements called fasciculations) are more common in the elderly. Inactive or immobile elderly people may experience weakness or abnormal sensations (paresthesias).
Muscle contractures may occur in those unable to move voluntarily or to have their muscles stretched through exercise. Restless leg syndrome may occur.
