Pushing the Limits of Arthrogryposis

Arthrogryposis multiplex congenita (AMC), or arthrogryposis for short, is a diagnosis characterized by multiple t contractures or stiffness of the ts. A contracture occurs when a t stiffens, resulting in a fixed bent or straight position and restricting its overall movement.

With AMC, contractures occur before birth and are non-progressive, resulting in weakness throughout the body. Because of the number of ts affected in each individual, the severity level will vary. In some cases, as few as 2-3 ts are affected. In other cases, all ts are affected, including the jaw and spine. However, the most affected are the legs and arms, and the first seems to be the most affected overall.

The cause of AMC is ultimately unknown. However, in some cases, decreased movement of the fetus in utero may have been the cause of this diagnosis since it is essential for the development of ts. Without it, connective tissue forms around the ts restricting movement, which ultimately causes the ts to stiffen.

At CRIT, patients with AMC benefit from rehabilitation services such as physical, occupational, and speech therapy. The treatment provided by our therapists helps to maximize the range of motion throughout all ts, improve overall functional mobility, and increase independence with activities for daily living.
