Abstract: A balance board comprising a platform (4) to support a user, a ground contacting rocker member (8) having a rounded surface (16) to permit pivoting of the platform about a first axis (10), and an interconnecting member (14) extending between the rocker member and the platform to permit pivoting of the platform about a second axis (11) substantially perpendicular to the first axis and about a third axis (12) substantially perpendicular to the first and second axes. The interconnecting member and the rocker member cooperate to define a central pivot region, for pivoting of the platform about the three axes. Preferably, the balance board includes stop members (30) to adjust the pivoting movement of the platform about at least one of the axes to make balancing of the platform adjustable depending on the skill level of the user. The balance board is used as an exercise device to improve and develop the balancing ability of a user.

Abstract: A torsion board comprising a platform for supporting a user, a ground contacting member for maintaining the torsion board generally in a fixed position and orientation with respect to a ground surface and a resilient interconnecting member mounted between the ground contacting member and the platform to permit pivoting of the platform about first, second and third orthogonal axes, said first axis being generally coincident with a gravitational axis along which gravitational forces act upon said user.
