**2.5. Information of patients with poor salivation affected by Sjögren's syndrome and others**

In **Figure 3**, we showed information of patients: eight women were *diagnosed with* Sjögren's syndrome and two women's symptoms were unexplained*. Patients with Sjögren's syndrome were diagnosed by contrast and/or scintigraphic studies. In particular, the patients with indefinite complaints were not given a definite diagnosis*; *nevertheless, they had poor salivation as their chief complaint.*


**Figure 3.** Information of subjects. Patients in 8 and 9 showed only poor salivation. Others are Sjögren's syndrome patients.

**3.4.** *The affected and unaffected* **patients on the vibrotactile stimulation**

*In* **Figure 5A**, we showed changes to saliva production (**Figure 5A-a**) and facial temperature (**Figure 5A-b**) in the *patients who were affected* followed the vibrotactile stimulation. On the other hand, in **Figure 5B**, we showed changes to saliva production (**Figure 5B-a**) and facial temperature (**Figure 5B-b**) in *patients who were not affected* followed the vibrotactile stimulation. As shown in **Figure 5A**, the saliva production (elevated state from avg. 0.2 to 1.5 ml) was exponentially increased after about 5 years. The finding was shown as changes to increased face temperature (in a positive direction). However, as shown in **Figure 5B**, the saliva produc-

*In* **Figures 5** and **6**, *affected* patients were divided into apocatastasis for a long period and for a short period. *Affected* patients with a long period were exponentially increased after about 6 (A), 5 (B) and 1.5 (D) years. Ones with a short period were exponentially increased after about 2 months (E). Facial temperature was increased *with* increased saliva production. On the other hand, in **Figure 7**, *in unaffected patients, the saliva production* and facial temperature

In **Figure 8**, we showed a survey and patients with satisfaction (good) or non-satisfaction (no/ yes or bad) were examined. Patients with satisfaction had many good tendencies, but ones
