Motor Disorders

Motor disorders are conditions that disrupt a person's ability to control, direct, or coordinate movements. This can be caused by a variety of conditions, including genetic or congenital factors, degenerative diseases, infections, neurological conditions, trauma, and even drug toxicity. Motor skills function is divided into two categories - fine motor and gross motor. Fine motor skills are the ability to make precise, small movements involving fingers, wrists, hands, and toe, while gross motor skills involve large movements like bending, kicking, and walking. Motor disorders can disrupt both types of movement. The most common motor disorders are cerebral palsy, dystonia, and spasticity. Cerebral palsy is a neurological disorder usually present from birth that disrupts the ability to control muscles. Dystonia is a neurological disorder that causes involuntary muscle contractions, leading to abnormal postures and repetitive movements. Other common motor disorders include dystonic movements such as tremor, akinesia, or rigidity, as well as ataxia, which involves loss of coordination or control of movement. Some motor disorders are also genetic, including Huntington’s Disease, a progressive disorder that affects the brain and nervous system. The diagnosis of motor disorders is made based on the presentation of symptoms, any underlying causes, the medical history and physical exam, as well as laboratory and imaging tests such as MRI or CT scans. Treatment varies depending on the disorder, but can include physical and occupational therapy, bracing, medications, and occasionally surgery. To improve quality of life, people living with motor disorders can take advantage of adaptive equipment and technologies. This may include wheelchairs, walkers, patient lifts, and voice-control adaptations to smartphones or computers. Additionally, support groups can be helpful in providing emotional and social support for those affected. Overall, motor disorders disrupt the ability to make the movements core to daily life, but there are treatments and technologies that can help improve quality of life.
