Biomechanical Evaluation of the Neck and Shoulder When Using Pillows with Various Inner Materials

Abstract: Objective: The purpose of this study was to evaluate of various material of pillows by using biomechanical variables such as the cervical stability, head pressure distribution, and muscle activity. Method: Eight subjects participated in the experiment. Three different materials such as polyester sponge, memory foam and the buckwheat shell used for Korean traditional pillow were tested. Electro-goniometer, six channels of electromyography(EMG), ten channels of the head pressure sensors were used to measure the … Show more

“…Levangie and Norkin (2005) mentioned that CCA in the standing position was the most ideal CCA value in the posture of the head and neck. Kim et al (2011), based on such a previous study, said 15° of CCA is the most ideal angle in the posture of the head and neck. Therefore the contoured pillow showed the result the most close to 15° of CCA of the ideal posture of the head and neck in the three types of pillows, based on the previous study.…”

“…Based on the studies (Levangie and Norkin, 2005;Kim et al, 2011) reporting that maintaining the 15 degrees of cervical curvature angle is an ideal posture of the head and neck, which is similar to a standing posture, this study measured and analyzed cervical curvature angle (CCA), and produced the anthropometric factors affecting the CCA.…”
