Trunk Muscle Activity Induced by Three Sizes of Wobble (Balance) Boards

A. Kim Burton

The effect on trunk muscle activity of three designs of wobble (balance) boards has been investigated electromyographically, in six subjects, in order to define the optimal dimensions of a wobble board that will stimulate such muscle activity. It is suggested that the dimensions required are a 350-mm diameter board set on a ball 50 mm high with a 55-mm radius of curvature, to provide a maximum angle of tilt of 15 O. The possible relationship between proprioception and lower limb/low back disorders is discussed and the suggestion made that wobble boards could be used in clinical trials of coordination training in these patients.
