Mental retardation - spasticity - ectrodactyly refers to a form of intellectual disability that is characterized mainly by below-average mental ability, unusual tightness of the muscles, and hand/foot birth defects (the absence of one or more central sections of the hand or foot). Individuals with this form of intellectual disability have problems performing tasks involving physical activity. Like other individuals with intellectual disability, an individual with this condition often has problems with reasoning and solving problems, as well as performing day-to-day tasks. The condition is often diagnosed during childhood. Doctors diagnose this form of intellectual disability if unusual muscle tightness and hand deformities are observed. Signs like walking and talking late, slow mastering of basic tasks, and having difficulty remembering things may also suggest this condition in children. Treatment is developed on a case-by-case basis and depends on the specific needs of the patient. Doctors may suggest the patient undergo surgery to fix hand and foot problems. Physical therapists may create an exercise plan to help individuals increase their muscle strength. Doctors seek help from various therapists and community services to provide support and care for families affected by intellectual disability.
