An apparatus for measuring the range of angular body motion about at least one axis of rotation. The apparatus includes a base with a first portion having means for engaging the body to provide a first reference point for measurement. A second portion of the base extends outward from the body generally perpendicular to the axis of rotation. A measurement member is positioned adjacent to the second portion of the base and is rotatably mounted to the base at the first reference point. The measurement member moves relative to the second portion of the base as the measurement member is pivoted about the axis of rotation. A slide arm is slidably mounted on the measurement member for sliding movement along a line substantially parallel to the plane of rotation of the measurement member. The slide arm has an outer end which is spaced from the measurement member and engages the body at a second reference point on an opposite side of the axis from the first reference point and there is measurable pivotal movement of the measurement member as the body is moved about the axis of rotation. A second portion of the apparatus uses angle indicators for measuring rotations of the spine about an upright axis and side to side pivotal movement.
