A physical disability is a limitation on a person's physical functioning, mobility, dexterity or stamina. Other physical disabilities include impairments which limit other facets of daily living, such as respiratory disorders, blindness, epilepsy and sleep disorders.
Prenatal disabilities are acquired before birth. These may be due to diseases or substances that have harmed the mother during pregnancy, embryonic or fetal developmental accidents or genetic disorders.
Perinatal disabilities are acquired during birth. These can be due to prolonged lack of oxygen or the obstruction of the respiratory tract, damage to the brain during birth (due to the accidental misuse of forceps, for example) or the baby being born prematurely.
Mobility impairment is a category of disability that includes people with varying types of physical disabilities. This type of disability includes upper or lower limb loss or disability, manual dexterity and disability in co-ordination with different organs of the body. Disability in mobility can either be a congenital or acquired with age problem. This problem could also be the consequence of disease. People who have a broken skeletal structure also fall into this category of disability.
Visual impairment is another type of physical impairment. There are hundreds of thousands of people who suffer greatly from minor to various serious vision injuries or impairments. These types of injuries can also result in some severe problems or diseases like blindness and ocular trauma. Some of the common types of vision impairments include scratched cornea, scratches on the sclera, diabetes-related eye conditions, dry eyes and corneal graft, macular degeneration due to old age and retinal detachment.
Hearing impairment is the category of physical impairment that includes people that are completely or partially deaf. People who are only partly deaf can sometimes make use of hearing aids to improve their hearing ability.
Physical impairment can also be attributed to disorders causing poor sleep quality, chronic fatigue, chronic pain, and seizures among other conditions.
