Trunk muscle activity induced by three sizes of wobble (balance) boards
Abstract:
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.
