Experimental design for sternocleidomastoid muscle stress measurement

Abstract

In this paper we assess the sternocleidomastoid muscle stress with two experimental studies to evaluate the developed smart neck support system. The first study involving head rotation angle and sternocleidomastoid muscle (SCM) electromyography (EMG) activity. This (descriptive) study extends efforts from different authors to assess the isometric strength of SCM, in which the experiment is carried out in relation to time. This first study functions as a calibration experiment which provides the input for the second study as a validation experiment. The validation experiment was conducted inside the aircraft cabin simulator. The SCM of participant was evaluated with electromyography. The smart neck support system is to reduce the SCM muscle stress of aircraft passenger adaptively during air travel.
