タッピングリズムの1/fゆらぎ解析による顎機能診断への可能性

抄録

In this study, the application of 1/f fluctuation in the diagnosis of temporomandibular function was investigated.
The subjects were five patients of temporomandibular disorders (the patient group), and five adult males with individual normal occlusion of the functional stomatognathic system were the controls (the control group). The following tooth-tapping were conducted for four minutes, recorded on sirognathographs.
Power spectrum densities obtained through the tapping interval times of between each a cycle were analyzed using the fast fouries transform analysis. And power spectrum densities were analyzed using the analysis of variance between the patient group and the control group.
As a result, a difference between the groups was found at the 1% levels, respectively.
