I'd be interested in opinions in the plundering of Ben Goldacre's Bad Science columns that was last night's Newsnight piece on Brain Gym [if you're quick you may get to view the video piece].
My sense is that what Brain Gym does (e.g. the actions it gets children to do) are not in themselves unhelpful. The relaxation, the exercise, the physical co-ordination issues it encourages: all in themselves seem fine. They help focus, distract those from other problems or just plain allow some space for de-stressing so that actual physical, scientifically measurable things can happen which DO help the body.
Where my problem does come is in how much can be claimed for it on an inherantly scientific basis: brain buttons etc do not to me suggested a particularly evidence-based scientific analysis of how the body and brain work.
