Effectiveness of the Gaze Direction Recognition Task for Chronic Neck Pain and Cervical Range of Motion: A Randomized Controlled Pilot Study

Figure 2

Experimental design of gaze direction recognition task. Each column represents the positional relationship between a subject and an experimenter with six numbered boxes. The subject is positioned behind the experimenter and views neck rotation of the experimenter who attempts to gaze randomly at one of six boxes placed on the table, and imagines which one of the boxes the experimenter directs his gaze upon. The subject was then asked to give a verbal response as to the box number of the experimenter’s gaze direction.
