“…Whenever the tester changes the hand force magnitude used to press the probe over the skin, the obtained images can waver easily. Therefore, when measuring the intramuscular blood flow before and after exercise loading, the position, incidence angle, and contact pressure must be kept constant [ 25 ].…”

“…Previous reports have described techniques used to maintain a constant position of the probe, such as a marker [ 33 ] and a fixing device [ 25 , 34 ]. In this study, it was necessary to remove the probe temporarily from the face between the experimental sessions.…”

“…e VI is known to be useful for measuring the blood circulation on ultrasound imaging and has been used to assess rheumatic arthritis [21], thyroid disease [22], gastric cancer [23], and ovarian cancer [24]. Several studies have used the VI to evaluate the intramuscular blood flow in appendicular skeletal muscles [25][26][27]. However, the VI has not yet been used to assess the masticatory and perioral muscles.…”

Background. The vascularity index (VI) is useful for measuring the hemodynamics on ultrasound imaging. However, there are no reports concerning the application of the VI to facial muscles. Objective. The aim of this study was (1) to establish a method of measuring the hemodynamics in facial muscles in a constant way and (2) to evaluate the hemodynamic changes in the masseter and superior orbicularis oris muscles (SOOMs) before and after exercise load in two subject groups of females of different ages. Methods. (1) The VI in the SOOM was calculated, and the test-retest reliability was assessed in seven healthy adults. (2) The VIs in the left-side masseter and SOOM were calculated in 3 sessions: before exercise loading (T0), immediately after loading (T1), and 5 minutes after T1 (T2) for the young adult group (YAG, n = 20; age range, 20–35 years) and the middle-aged to old group (MOG, n = 20; age range, 50–70 years). Tasks were gum chewing for the masseter muscle and lip sealing for the SOOM. The differences in the mean peak flows between two sessions were examined. Results. (1) Significant differences were not noted for the repeatedly measured average volumes of blood flow with good test-retest agreement (intraclass correlation coefficient = 0.81). (2) In both muscles of the YAG, there were a significant increase in T1 compared with T0 and a significant decrease in T2 compared with T1 (all p < 0.05 ). In both muscles of the MOG, no significant differences were noted in either comparison. Conclusions. A method of measuring the hemodynamics in facial muscles was developed and showed good reliability. Changes in the blood flow after exercise load in these muscles may vary with age in women.
