You may remember last year during the ACQUIRE program I described a possible phenomenon that is a result of the child either thinking about and/or actually moving their unaffected side while casted each time they practice a skill with their affected side. This can result in an association being created in their brain that becomes a habit.
If two activities happen simultaneously inside our brains, connections are basically "wired together".
Last year this did not happen to Madalyn. I hypothesized (or did I read it??, who knows) that it happens to "more affected" children. However, since it did happen this time, I'm guessing is possibly has something to do with her age. Or maybe last year she did not think about her unaffected side doing the activity during therapy and this time she did. I mostly ponder this because it is interesting to me, not that knowing "why" will make a difference in Madalyn's future.
This "habit" or "connection" should go away after a bit, and her bilateral use should not be affected. But for now, when she does a difficult activity that she practiced during ACQUIRE, her right hand inadvertently performs the the activity simultaneously...
Here's a video of her one week post ACQUIRE program:
