Physical disabilities are neuromotor impairments, such as epilepsy and cerebral palsy, or muscular/skeletal conditions, such as missing limbs and arthritis, according to Education.com. Physical disabilities are defined as congenital or acquired.
The brain, spinal cord and/or nervous system can have neuromotor impairments, notes the Ohio Department of Education. These impairments alter communication to the muscles and nerves of the body. Epilepsy is caused by disruption in the brain's nerve cell activity, resulting in seizures. Cerebral palsy is caused by abnormal brain development or injury during development. Cerebral palsy manifests itself by abnormal movement and muscle coordination in some or all limbs. Muscular dystrophy and spina bifida are also neuromotor impairments.
Education.com describes muscular/skeletal conditions are impairments or pain to joints, muscles, nerves and other body parts, which is not caused by central nervous system damage. The most common ones are limb deficiencies such as club feet, missing limbs or non-functioning limbs. Rheumatoid arthritis caused by inflammation in joints is a painful muscular/skeletal condition.
Congenital physical disabilities are those present before or during birth. These can be a result of stroke, poor fetal development or genetics, explains Oxford Bibliographies. Acquired disabilities develop from injury or disease while the person is otherwise healthy.
