The resulting mechanical energy surfaces were then least-squared fitted with an analytical function that was linear in time and quadratic in flexion-extension alignment angle. The least-squares analysis showed that there was a flexion-extension adjustment that minimized the mechanical energy expenditure and that this optimal adjustment was very close to the design point set by certified prosthetists.<\/jats:p>","DOI":"10.1115\/1.3108457","type":"journal-article","created":{"date-parts":[[2009,6,12]],"date-time":"2009-06-12T22:34:35Z","timestamp":1244846075000},"page":"386-391","update-policy":"http:\/\/dx.doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":2,"title":["Analytical Description of Minimum Energy Expenditure Surfaces"],"prefix":"10.1115","volume":"110","author":[{"given":"D.
