⩥ Disease-related disability. Answer: Example: decreased exercise
tolerance in a chronic smoker with chronic lung disease;
⩥ disuse-related disability. Answer: Example: shortness of breath on
minimal exertion in a sedentary older person
⩥ misuse-related disability. Answer: knee arthritis in a former football
player
⩥ disability related to physiologic aging. Answer: trouble reading fine
print in a 50-year-old
⩥ If the problem is disease. Answer: medical treatment is indicated.
⩥ If the problem is disuse. Answer: can often be cured with an activity
regimen.
⩥ If the problem is misuse. Answer: prior damage cannot be reversed

, ⩥ If the problem is physiologic aging. Answer: steps should be taken to
adapt and compensate for the disability.
⩥ common physiologic changes noted with aging. Answer: • The age at
which reading glasses are needed because of reduced lens elasticity is
between 42 and 50 years.
•Vestibular sensitivity gradually increases until about age 60 years,
which is one of the reasons why adults have increasing trouble on
amusement park rides as they age.
• Fertility in women peaks between 15 and 25 years and declines
thereafter, with menopause typically occurring about age 50 years

teenagers are usually far better at games of speed—including many

• The amount of sway a person will experience if asked to stand still
with eyes closed is high in early childhood, is minimized between about
ages 15 and 16 years, and then gradually increases beyond age 60 years.
• Ankle jerk reflexes are increasingly diminished or absent with older
age, in the absence of detectable musculoskeletal pathology.
• Bone density plateaus between ages 20 and 50 years, then gradually
declines, with the slope of decline being more rapid in women than in
men.
