I think there are a very limited number of studies but our insurance covers it and I figured it wouldn't hurt. She did improve a lot each session with the metronome (except for the session where she wasn't medicated, she went way down), but whether this somehow carries over to other motor skills I don't know. DD has had about 7 piano lessons. Her piano teacher was mystified a several weeks ago because DD had a terrible time switching back and forth between her hands (and she said she doesn't normally see that problem with kids, esp. kids as bright as DD) and now she does that no problem and can read music with two staffs, playing with both hands at the same time, although maybe it would have clicked for her even without the IM therapy. She's only had about 4 sessions of IM therapy and her score went up so much that she really wasn't making any mistakes so the OT talked about discontinuing it, but now that her score went way down without the meds I don't know if she'll want to continue or not.
DS tried it a couple years ago when he was 4-5 and never seemed to get the hang of it and never seemed to improve. Maybe he was just too young. It would be interesting to try it again and see what happens.
