This is Ingrid's brace. She will have something like this until she reaches skeletal maturity, maybe longer. Skeletal maturity will be in her late teens.
Ingrid attends physical therapy twice a week where she is working on her gait and exercising the muscle in her thigh that controls her knee (something she hasn't used in about a year).
I am constantly amazed by this girl's spunk, tenacity, and humor.
