Normal stresses on the patellar tendon and gastrocnemius were related to the axial force and flexion-extension moment of the prosthesis via a matrix equation. Elements of this matrix, influence factors calculated by least-squares algorithms, identified the contributions of each time-dependent load component acting to produce the time-dependent normal stresses. The flexion-extension angular sensitivity of the way these sagittal plane loads combined to produce normal stresses was included in the matrix equation via a first-order Maclaurin series. Highly favorable correlation coefficients between empirically measured and theoretically predicted stump stresses were calculated. This demonstrated that, in future studies, using an influence-factor matrix holds promise for quantifying sensitivities of normal stresses of the stump to multiple adjustments in prostheses.<\/jats:p>","DOI":"10.1115\/1.3138675","type":"journal-article","created":{"date-parts":[[2009,6,12]],"date-time":"2009-06-12T22:34:35Z","timestamp":1244846075000},"page":"238-246","update-policy":"http:\/\/dx.doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":18,"title":["Least-Squares Matrix Correlations Between Stump Stresses and Prosthesis Loads for Below-Knee Amputees"],"prefix":"10.1115","volume":"109","author":[{"given":"D.
