Here is the report from Ben's mother.
"Tue 6th June
We have re-introduced Ben to his walking frame while in the classroom for half of the day (Koko's note: Ben used to use walking frame for almost all day at school, until a few month ago when growing pain started to annoy him). He coped very well with this, even though it was tiring.
We brought COGY to school at the end of the day. A lot of the children were crowded around Ben asking him about COGY. They all wanted a turn, but Ben has no intention on sharing (koko's note: LOL). Ben has gotten into a good habit of counting the pedalling backwards to manoeuvre in small areas (Koko's note: video -1'10" to -0'55"). He spent about 30 minutes pedalling COGY before we went home.
He has not complained any pain, so this exercise seems to be very good for Ben."
