Abstract: An inclination measuring device (10) is provided, which includes an inclination tracking device (12) configured to pass over the object, having a plurality of elements, whose angle of inclination is to be mapped and a sensor probe (14) in communication with the inclination tracking device (12). The sensor probe (14) is configured to sense the position of each of the plurality of elements. The inclination measuring device (10) is useful for measuring the angle of trunk inclination or rotation of a person's trunk.
