Down’s Syndrome strength

[Kimera757]

The most common musculoskeletal effects of Down syndrome include weak muscle tone ( hypotonia ) and ligaments that are too loose (ligament laxity). This leads to excessive joint flexibility.

I knew about the poor muscle tone before (from going to camp as a kid and dealing with some children with that condition) but I learned a bit more today.

I do not believe this is the case with every person with Down’s syndrome. It appears the child you are talking about doesn’t have that, and given the level of strength might grow up to be an athlete.
