I do mean that! We should perhaps saw of their bottoms and use them as lazy susan's for serving pizza

I don't mean to be rude by the way but a lot of development and cost goes into things that aren't really that valid a tool for achieving what they are sold to achieve. This doesn't mean wobble boards don't have a use, just not a balance retrainers that's all.

p.s. in relation to the study, it was done with individuals without balance problems to being with, college students! And it was compared to a no treatment group. My suggestion is that standing on one leg, or doing tai chi would perhaps be better and cost nothing. It would be interesting to look at the cost impact of these 'Free' ideas when compared to expensive 'wobble board' type training. Of course a woddble board will strengthen the musculature in the lower leg, peroneals, soleus, gastrocnemius in an over active manner. These are often the secondary defense during a loss of balance, especially an inversion of the ankle. The primary defense is however control about the hip joint - something the wobble board doesn't really address. Thus I would personally suggest that excessive wobble board training would in fact neglect the proactive areas that need training to prevent a fall, and simply strengthen secondary mechanisms that try to assist recovery. This might help of course if you decide never to address the primary issues.

Please do other people have comments on this. I am excited that you have developed a device that does not necessarily have to go on a wobble board! Thus it might be rather useful for other ideas of balance training.
