The aim of this study was to assess the crosstalk errors due to endblock misalignments and to propose a procedure to compensate for these errors in knee applications. A precision jig was used to simulate pure \u00b1100\u00b0 flexion\/extension movements. A goniometer was mounted with various degrees of valgus\/varus (\u00b120\u00b0) and rotation (\u00b130\u00b0) misalignments. For valgus\/varus misalignments, although offset compensation eliminated the error in the valgus\/varus recordings for 0\u00b0 of flexion\/extension and reduced it to a few degrees for small (\u00b130\u00b0) flexion\/extension angles (root mean square error = 1.1\u00b0), the individual crosstalk caused pronounced errors for large (\u00b1100\u00b0) angles (18.8\u00b0). Subsequent compensation for this crosstalk reduced these errors to 0.8\u00b0 and 4.5\u00b0, respectively. For rotational misalignment, compensation for the general crosstalk by means of coordinate system rotation, in combination with compensation for the individual crosstalk, reduced the errors for small (\u00b130\u00b0) and large (\u00b1100\u00b0) flexion\/extension angles from 3.6\u00b0 to 0.5\u00b0 and from 15.5\u00b0 to 2.4\u00b0, respectively. Crosstalk errors were efficiently compensated by the procedures applied, which might be useful in preprocessing of knee functional data, thereby substantially improving goniometer accuracy.<\/jats:p>","DOI":"10.3390\/s101109994","type":"journal-article","created":{"date-parts":[[2010,11,9]],"date-time":"2010-11-09T11:57:47Z","timestamp":1289303867000},"page":"9994-10005","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Goniometer Crosstalk Compensation for Knee Joint Applications"],"prefix":"10.3390","volume":"10","author":[{"given":"Tatiana de Oliveira","family":"Sato","sequence":"first","affiliation":[{"name":"Department of Physical Therapy, Universidade Federal de S\u00e3o Carlos, CP 676, CEP 13565-905, S\u00e3o Carlos, SP, Brazil"}]},{"given":"Gert-\u00c5ke","family":"Hansson","sequence":"additional","affiliation":[{"name":"Division of Occupational and Environmental Medicine, University Hospital, SE-22185, Lund, Sweden"}]},{"given":"Helenice Jane Cote Gil","family":"Coury","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Universidade Federal de S\u00e3o Carlos, CP 676, CEP 13565-905, S\u00e3o Carlos, SP, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2010,11,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"246","DOI":"10.1016\/j.jbiomech.2004.11.023","article-title":"Quadriceps femoris electromyogram during concentric, isometric and eccentric phases of fatiguing dynamic knee extensions","volume":"39","author":"Pincivero","year":"2006","journal-title":"J.
