Abstract

Many Japanese people experience physical symptoms known as Katakori (shoulder stiffness or neck pain), which is considered a psychosomatic phenomenon that is strongly correlated with psychological stress and stress caused by human relationships. This study examined changes in the chaos of eye movement accompanied by changes in depression by treating shoulder stiffness. Participants scoring over 1SD from the mean score having high depression and shoulder stiffness were included in the intervention group and provided stretching intervention. The control group included participants having high depression and shoulder stiffness, but they were not provided with the stretching intervention. Moreover, participants scoring lower than 1SD from the mean score having low depression and no shoulder stiffness were included in the Low group. The experimental group exercised using a neck and shoulder relaxation technique using a stretch pole recommended by the stretch pole official site. The results of the experiment indicated that eye movement LLE(Largest Lyapunov Exponent) changed more significantly when the depression level was high. Moreover, LLE and the degree of change in LLE decreased after receiving treatment for the stiff shoulder. It is suggested that the chaotic fluctuation of eye movement might decrease when depression improved, i.e., in people with low depression.
