Arthrogryposis is a term used to describe a number of rare conditions characterized by stiff joints and abnormally developed muscles.

  • It’s also referred to as arthrogryposis multiplex congenital, or amyloplasia.
  • Arthrogryposis is not thought to be a genetic or hereditary condition.
  • The exact cause of arthrogryposis is unknown, but a number of different theories have been proposed:
    • Some believe that arthrogryposis is caused by obstructions to intrauterine movement during pregnancy.
    • Others believe that it may be a result of an early viral infection during a baby’s development.
    • Others believe that arthrogryposis is the result of failure of the central nervous system and/or muscular system to develop appropriately.

Children’s Hospital Boston’s approach

Your child will undergo a course of occupational therapy, which will help improve her flexibility and strength in the joints and muscles. Specialists in the Occupational Therapy Program at Children’s will collaborate with you and your child’s doctor to provide the best possible care for your child.

Treatment programs are based on thorough evaluations and are always individualized to meet the needs of your child.

The future of pediatrics will be forged by thinking differently, breaking paradigms and joining together in a shared vision of tackling the toughest challenges before us.”
