摘要： The measurement device includes a frame with a support and mounting member, a longitudinal bar, a lateral bar pivotally and slidably attached to the longitudinal bar with a pair of stirrups or heel cups attached symmetrically on either side of the longitudinal bar at a known distance from the longitudinal bar. A plurality of potentiometers or other resistive measurement devices are attached to the two bars to provide analog measurements of lengthwise and angular displacement. A microprocessor controller calculates actual leg length and offset by combining the measurements obtained from the first two resistive elements using a simple trigonometric function. An output means in the form of an LED and/or LCD display provides a visual display of the calculated actual and offset values.
