Electronic cervical range of motion measurement system: Sagittal flexion and extension, lateral flexion and extension

Studies showed that cervical range of motion is affected by injury to the neck. Cervical range of motion measurements are aided by effective cervical range of motion measurement techniques. The goal of this thesis is to design, build, and characterize an effective portable electronic cervical range of motion measurement system, in particular, the tilt sensing system, which may one day aid in the diagnosis and treatment of neck pain-related injuries and diseases.; The Electronic Range of Motion (EROM) device presented in this thesis is composed of integrated circuit tilt sensors, integrated circuit rotation sensors, an integrated circuit microconverter, a personal computer, and sensor head mounting apparatus. The system was designed to measure the three most commonly measured ranges of motion of the cervical spine: Sagittal flexion and extension, lateral flexion and extension, and axial rotation. The focus of the thesis is on tilt sensing system which measures Sagittal flexion and extension, lateral flexion and extension.
