Characteristics of the rocking board.

Board Characteristics
Typology of instability			Rocking
Rolling structure			Section of a cylinder
Radius of the rolling structure (changeable)			55-80-110 mm
Distance of the plantar surface from the ground			50 mm
Degrees of freedom			1 (single axis)
Range of motion	Mobile roll axis (x)	Inclination	± 15°
		Rolling	≈30-45-60 mm (rolling radius 55-80-110 mm)
	Mobile pitch axis (y)	Inclination	0°
		Rolling	0°
	Yaw axis (z)	Rotation	0°
Frequency enhancer			Feedback/feedforward

The rocking motion is a complex movement that includes the rolling of a cylindrical surface and the consequent inclination of the moving plate.
