CLIN BIOMECH , 2004, vol. 19, n° 7, p. 711-718 Doc n°: 114714 Localisation : Documentation IRR Descripteurs : EC25 -ORTHESES DE MEMBRE INFERIEUR Objective. To establish the range of forces and moments applied to lower limb orthoses during ambulation by routine users. Design. Well-established gait analysis techniques were used to determine the loading at the major joints. It was assumed that the joint moments were transmitted by the orthosis encompassing any particular joint. Two hundred and five assessments of 164 patients were successfully completed by a consortium of four gait laboratories in Europe. The orthosis specification and patient clinical data were also recorded. Background. The design and development of orthoses has occurred largely by evolution rather than by formal engineering methods. In particular, formal design has been hampered by a lack of information oil the forces and moments applied during ambulation. Methods. A standard gait analysis procedure was employed to capture the data. Langue : ANGLAIS |
