Accuracy and reliability of a digital imaging system compared with the Universal Goniometer for assessing cervical range of motion in infants with torticollis

This two-part study investigated the accuracy and reliability of a new ‘Electronic Portable Anthropometric Evaluation Device’ (ePAED) for assessment of cervical range of motion in infants with torticollis. The e-PAED was compared to the universal goniometer, currently the most commonly used clinical tool for measuring cervical range in infants. Part one involved a laboratory study comparing the ability of the e-PAED and the goniometer to measure the angle of four diagrams of known dimensions. Part two was a clinical trial involving measurement of cervical range of motion of seventeen infants with normal through to severe limitation. Two researchers measured cervical rotation and lateral flexion using both the goniometer and the ePAED
