A Novel Electronic Cervical Range of Motion Measurement System

Abstract

In this article we describe the design of a novel, portable, head-mounting, electronic system to measure the ranges of motion of the cervical spine (CROM). The device used monolithic integrated circuits such as: accelerometers, gyroscopes and a single-chip 12-bit data acquisition system. This Electronic Cervical Range of Motion measurement system is connected to a personal computer interface that allows for efficient and reliable data transfer, thereby limiting the potential for human calculation and transcription errors. Overall, the system is accurate, reliable, portable, low-cost, and user-friendly. Furthermore, the system displays specific instructions to the user, in order to insure proper measurement technique and to limit inter-user error.
