摘要：A device for measuring the angle of curvature of the lumbar spine of a subjectincludes a flexible, elongate member disposed parallel, and fixed at one point, to thelumbar back of the subject. A second point of the elongate member displaces when thesubject bends forwardly or rearwardly from an initial position. A displacement sensor,coupled to the elongate member, determines displacement of the second point whenthe subject bends forwardly or rearwardly. The device also includes AF and pelvic
inclinometers for respectively measuring the rotational angles of the thorax and pelvis ofthe subject as well as a rotary potentiometer for measuring the twisting angle of thetrunk of the subject. The device can be used as a field device for providing suchmeasurements while the subject carries on normal physical activity.
