We aim to study dynamic nerve-tendon interrelationships in normal and mild CTS wrists during a fist motion, with dynamic ultrasound. We observed that in normal wrists, the nerve arcs in an ulnar-volar direction and changes from a circular shape to a flat oval during motion. In CTS candidates, however, the curvature and distance of the nerve's path are reduced, while nerve shape remains relatively constant. In all candidates, the nerve is compressed against the flexor retinaculum, with the nerve subject to less compression in normal candidates as it moves dorsally into a recess. These findings suggest that besides mechanical compression from increased carpal tunnel contents alone, a decrease in nerve gliding movement may lead to CTS symptomatology. Furthermore, we identified that maximum nerve deformation occurs mid-motion, supporting the use of wrist splints for symptom relief.<\/jats:p>","DOI":"10.1142\/s0218810413500238","type":"journal-article","created":{"date-parts":[[2013,7,3]],"date-time":"2013-07-03T04:04:59Z","timestamp":1372824299000},"page":"193-202","source":"Crossref","is-referenced-by-count":13,"title":["MID-MOTION DEFORMATION OF MEDIAN NERVE DURING FINGER FLEXION: A NEW INSIGHT INTO THE DYNAMIC AETIOLOGY OF CARPAL TUNNEL SYNDROME"],"prefix":"10.1142","volume":"18","author":[{"given":"Kyrin","family":"Liong","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, National University of Singapore, 9 Engineering Drive 1, Block EA, 07-08, Singapore 117576, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amitabha","family":"Lahiri","sequence":"additional","affiliation":[{"name":"Department of Hand and Reconstructive Microsurgery, National University Hospital, 5 Lower Kent Ridge Road, Main Building 1, Level 2, Singapore 119074, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shujin","family":"Lee","sequence":"additional","affiliation":[{"name":"Division of Plastic, Reconstructive and Aesthetic Surgery, National University Hospital, 5 Lower Kent Ridge Road, Kent Ridge Wing 2, Level 4, Singapore 119074, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dawn","family":"Chia","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, National University Hospital, 5 Lower Kent Ridge Road, Kent Ridge Wing 2, Level 3, Singapore 119074, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arijit","family":"Biswas","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, National University Hospital, 5 Lower Kent Ridge Road, Kent Ridge Wing 2, Level 3, Singapore 119074, Singapore"},{"name":"Department of Obstetrics and Gynecology, Yong Loo Lin School of Medicine, National University of Singapore, 1E Lower Kent Ridge Road, NUHS Tower Block, Level 12, Singapore 119228, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heow Pueh","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, National University of Singapore, 9 Engineering Drive 1, Block EA, 07-08, Singapore 117576, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2013,7,3]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbspin.2007.09.014"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1016\/j.berh.2011.01.014"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.08.1433"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1007\/s00776-009-1416-x"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.H.01653"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1590\/S1413-78522006000300002"},{"key":"rf7","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2011.02.030"},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1016\/j.pmrj.2011.04.009"},{"key":"rf10","doi-asserted-by":"publisher","DOI":"10.1002\/ca.20379"},{"key":"rf11","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2007.09.017"},{"key":"rf12","doi-asserted-by":"crossref","first-page":"149","DOI":"10.7863\/jum.2007.26.2.149","volume":"26","author":"Oh S.","year":"2007","journal-title":"J.
