Here is the skinny, Arthrogryposis Multiplex Congenita (AMC) is a congenital neuromuscular disorder characterized by muscle weakness and associated joint contractures. At birth, babies frequently have clubfeet and flexed wrists but can also have contractures of any joints in the body. Muscle weakness is associated with a defect in the anterior horn cell of the spinal cord. This area of the spinal cord can be considered the power plant for the muscles. Since it supplies the electrical current from the spinal cord, to the motor nerves which feed the muscles which they move. AMC has similar basis of anterior horn cell disease as polio does and with aging, it has similar problems with over use issues that polio does.
Little is published about Arthrogryposis and aging but of the few articles, it supports, as the person ages, they become much more disabled.
What we all know, who live with this, is that it hasn’t stopped any of us from doing what we wanted and how we wanted. From my perspective and possibly some of yours, I learned how to crawl, talk, walk, tie shoes, run, jump, ride a bike, think for myself, go to schools, drive, go to college, find a job I love, just like everyone else. The only difference, aside from the obvious, I can truly say, I figured it all out as I went, as I am certain many, if not everyone else has.
