On the estimate of the two dominant axes of the knee using an instrumented spatial linkage.
This article presents the validation of a technique to assess the appropriateness of a 2 degree-of-freedom model for the human knee, and, in which case, the dominant axes of flexion/extension and internal/external longitudinal rotation are estimated. The technique relies on the use of an instrumented spatial linkage for the accurate detection of passive knee kinematics, and it is based on the a...
متن کاملThe transepicondylar axis approximates the optimal flexion axis of the knee.
The traditional understanding of knee kinematics holds that no single fixed axis of rotation exists in the knee. In contrast, a recent hypothesis suggests that knee kinematics are better described simply as two simultaneous rotations occurring about fixed axes. Knee flexion and extension occurs about an optimal flexion axis fixed in the femur, whereas tibial internal and external rotations occu...
متن کاملQuasi-Real Time Estimation of Angular Kinematics Using Single-Axis Accelerometers
In human movement modeling, the problem of multi-link kinematics estimation by means of inertial measurement units has been investigated by several authors through efficient sensor fusion algorithms. In this perspective a single inertial measurement unit per link is required. This set-up is not cost-effective compared with a solution in which a single-axis accelerometer per link is used. In thi...
متن کاملComparison of the effects of external instruction exercises in combination with hip-knee strengthening on gait kinematics in patients with patellofemoral pain syndrome: a randomized clinical trial.
Aims and Background: Patellofemoral pain syndrome is one of the most common musculoskeletal disorders, and is related to biomechanical factors of the lower extremities. The purpose of this study was to compare the effect of hip and knee strengthening with internal instruction exercises on pain and dynamic knee valgus in patients with Patellofemoral pain syndrom. Materials and Methods: 50 men a...
متن کاملComparisons of bracing and patellar taping on knee three-dimensional kinematics of women with patellofemoral pain syndrome in stance phase of running
Introduction: Patellofemoral pain syndrome (PFPS) is one of the most common knee injuries that accounted for between 25-40% of all knee problems presenting to sports medicine centers. Two treatment methods of bracing and taping are recommended in these patients that their effectiveness are unclear. The aim of this study was to evaluate the efficacy of the two treatment methods on knee three-dim...
