A functional electrical stimulation step and stand system comprising two footplates connected to a primary drive motor that cause the footplates to move in a reciprocal motion. A substrate is provided which comprises a first mass and a second mass. The gate electrode layer and the gate lead line are electrically connected with each other by way of a resistor made of polysilicon containing an impurity, and an impurity concentration in polysilicon which forms the resistor is lower than an impurity concentration in polysilicon which forms the gate electrode layer. By the means of the invention, the handicap number of the golfer can be predicted with good accuracy by monitoring several his or her subsequent swings. The first tank may include first and second compartments partially separated by a divider with a top whereby process liquid in the first compartment flows over the top of the divider into the second compartment.
