Interesting opinion PhysioBob. I know the ground does not move like a wobble board BUT wobble boards certainly have established themselves over the years as useful tools in not only balance training but also rehab of ankle, knee and hip conditions. You almost make it sound like we should all be throwing away our wobble boards and I dont think you meant that.

Found some research - have a look at http://www.pubmedcentral.nih.gov/art...medid=15767608
Effectiveness of a home-based balance-training program in reducing sports-related injuries among healthy adolescents: a cluster randomized controlled trial
Carolyn A. Emery, J. David Cassidy, Terry P. Klassen, Rhonda J. Rosychuk, and Brian H. Rowe
This study shows that balance training on a wobble board is indeed beneficial.

Maybe this is an interesting subject to discuss in another forum where there are more people to contribute?
