People with Down syndrome have a laxity of the ligaments and more flexibility in their tendons and ligaments. Because of this, they face a greater risk of bunions, ankle instability, flat feet, and knee and hip problems. More than 95% of people with Down syndrome have flat feet.
Chromosome 21 is the chromosome associated with Down syndrome. Chromosone 21 is responsible for the production of collagen, an important protein that forms ligaments, tendons, cartilage, bone and the support structure of the skin. Laxity of the ligaments allows pronation, or collapse of the arch. This causes the shin, the knee and other parts of the leg to move in ways they weren't intended to. Leg aches, knee pain, hip pain and even neck pain can result.
J1 Insoles' patented design for flat feet have proven to be an effective treatment for people with Down syndrome. Dr. Riley has been a speaker at the National Down Syndrome Conference and also has a j1 Insoles booth at the convention.
