The developed sensor can simultaneously measure the forefoot activity (FA) and minimum toe clearance (MTC). The FA was evaluated through the change in the contact area captured by a camera using a method based on a light conductive plate. The MTC was derived from the distance between the bottom surface of the clog and ground obtained using a time of flight (TOF) sensor, and the clog posture was obtained using an acceleration sensor. The induced fatigue was achieved by walking on a treadmill at the fastest walking speed. We evaluated the FA and MTC before and after fatigue in both feet for 14 participants. The effects of fatigue manifested in either the FA or MTC of either foot when the results were evaluated by considering the participants individually, although individual variances in the effects of fatigue were observed. In the dominant foot, a significant increase in either the FA or MTC was observed in 13 of the 14 participants. The mean MTC in the dominant foot increased significantly (p = 0.038) when the results were evaluated by considering the participants as a group.<\/jats:p>","DOI":"10.3390\/s22239300","type":"journal-article","created":{"date-parts":[[2022,11,30]],"date-time":"2022-11-30T08:46:41Z","timestamp":1669798001000},"page":"9300","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Fatigue Effect on Minimal Toe Clearance and Toe Activity during Walking"],"prefix":"10.3390","volume":"22","author":[{"given":"Yingjie","family":"Jin","sequence":"first","affiliation":[{"name":"Graduated School of Natural Science and Technology, Kanazawa University, Kakuma-machi, Kanazawa 920-1192, Japan"}]},{"given":"Yui","family":"Sano","sequence":"additional","affiliation":[{"name":"Graduated School of Natural Science and Technology, Kanazawa University, Kakuma-machi, Kanazawa 920-1192, Japan"}]},{"given":"Miho","family":"Shogenji","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Institute of Medical, Pharmaceutical and Health Sciences, Kanazawa University, Kanazawa 920-0942, Japan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2549-1435","authenticated-orcid":false,"given":"Tetsuyou","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Faculty of Frontier Engineering, Institute of Science and Engineering, Kanazawa University, Kakuma-machi, Kanazawa 920-1192, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"426","DOI":"10.1111\/j.1532-5415.2000.tb04702.x","article-title":"Fatigue in an older population","volume":"48","author":"Liao","year":"2000","journal-title":"J.
