Physical Disability

Physical disability refers to a range of conditions that affect a person’s mobility, dexterity, or physical functioning. Physical disability may be congenital, resulting from birth, or acquired due to disease, injury, or the natural aging process.

A physical disability is a limitation on a person’s physical functioning, mobility, dexterity, or stamina. Other physical disabilities include impairments that limit other aspects of daily life, such as respiratory disorders, blindness, epilepsy, and sleep disorders.

Physical Disability Causes

Prenatal disabilities are acquired before birth. They may be caused by diseases or substances the mother has been exposed to during pregnancy, developmental accidents of the embryo or fetus, or genetic disorders.

Pernatal disabilities are acquired in humans from a few weeks before birth to four weeks after birth.[5] They may be caused by prolonged lack of oxygen or obstruction of the respiratory tract, damage to the brain during birth (for example, due to accidental misuse of forceps), or premature birth. These can also be caused by genetic disorders or accidents.

Postnatal disabilities are acquired after birth. These can be caused by accidents, injuries, obesity, infections or other diseases. These can also be caused by genetic disorders.

Physical Disability Types

Mobility impairment includes loss or weakness of the upper or lower limb, poor manual dexterity and damage to one or multiple body parts. Impairment in mobility can be the result of a congenital or acquired problem or disease. People who have a broken skeletal structure also fall into this category.

Visual impairment is another type of physical impairment. There are hundreds of thousands of people who suffer from minor to several severe vision injuries or deficiencies. These types of injuries can also result in serious problems or diseases such as blindness and ocular trauma. Some other types of vision impairment include scratched cornea, scratches on the sclera, diabetes-related eye conditions, dry eyes and corneal grafts, macular degeneration in old age and retinal detachment.

Hearing impairment is the partial or complete inability to hear. Deaf and hard-of-hearing people have a rich culture and benefit from learning sign language for communication purposes. People who are only partially deaf can sometimes use hearing aids to improve their hearing ability. Speech and language disabilities: Individuals with deviations in speech and language processes that are outside the range of acceptable deviations in a given environment and that prevent full social or educational development

Physical impairments can be attributed to sleep deprivation, chronic fatigue, chronic pain, and seizures, among other disorders.
