OBJECTIVE: The objective of this paper was to examine and link the disparate measures of motor, vision, and brain activity for elderly and young adults. METHOD: The participants were 15 elderly adults and 10 young adults. Accelerometry, eye tracking, and prefrontal cortex (PFC) activity in the functional near-infrared spectroscopy (fNIRS) were used to evaluate the participants in a 10-m walking test. RESULT: The results for the elderly adults were 1) low variabilities of velocity and acceleration along the front-back and up-down axes, 2) a wider gaze range on the right-left axis than the young adults, 3) a high mean PFC activity, and 4) a larger number of high-relation pairs than the young adults for the correlation coefficients of both gait vs. gaze and gait vs. PFC activity. The variabilities of velocity and acceleration, gaze and PFC activity changes for the young adults were selective. CONCLUSION: Measuring 10-m walking in a polymetric approach may capture some indicators related to physical and cognitive difficulties such as frailty and dementia.<\/jats:p>","DOI":"10.3233\/thc-220447","type":"journal-article","created":{"date-parts":[[2023,8,4]],"date-time":"2023-08-04T12:46:17Z","timestamp":1691153177000},"page":"551-563","source":"Crossref","is-referenced-by-count":1,"title":["A polymetric approach for measuring brain activity and behavior: Considerations for gait, gaze and fNIRS measurements in a 10-m walking of elderly and young adults"],"prefix":"10.1177","volume":"32","author":[{"given":"Mizue","family":"Kayama","sequence":"first","affiliation":[{"name":"Graduate School of Medicine, Science and Technology, Shinshu University, Nagano, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Nagai","sequence":"additional","affiliation":[{"name":"Faculty of Technologists, Institute of Technologists, Saitama, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takao","family":"Futagami","sequence":"additional","affiliation":[{"name":"Graduate School of Medicine, Science and Technology, Shinshu University, Nagano, Japan"},{"name":"Toyo Corp., Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koji","family":"Terasawa","sequence":"additional","affiliation":[{"name":"Graduate School of Medicine, Science and Technology, Shinshu University, Nagano, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"issue":"3","key":"10.3233\/THC-220447_ref4","doi-asserted-by":"publisher","first-page":"303","DOI":"10.1001\/archneur.56.3.303","article-title":"Mild cognitive impairment: Clinical characterization and outcome","volume":"56","author":"Petersen","year":"1999","journal-title":"Arch.
