With five interchangeable fulcrums, this balance training tool can be used with a wide range of patients. Three different fulcrums at 6º, 9º and 12º make the wooded board a single-plane rocker with varying degrees of difficulty. Two multi-directional fulcrums at 10º (one square and one round) provide a greater challenge in multiple planes. Fulcrums attach to the board with Velcro fasteners.
