Test-retest reliability of 3D kinematic gait variables in hip osteoarthritis patients
2011
Import JabRef | WosArea Orthopedics; Rheumatology; International audience; Objectives: (1) to investigate the test-retest reliability of 3D gait analysis (3DGA) in hip Osteoarthritis (OA) patients; (2) to find the minimum number of gait trials needed to overcome intrinsic variability; (3) to check the accuracy of angles measured by the 3D system. Design: 23 Patients suffering from hip OA with no other major disease were recruited. We evaluated the reliability of spatio-temporal variables and body angles (lower-limb joints, trunk and pelvis angles) during two sessions of 3DGA using intra-class correlation coefficients (ICC). The minimum number of trials needed to overcome intrinsic variabili…
Brain Injured Patients versus Multiple Trauma Patients: Some Neurobehavioral and Psychopathological Aspects
2006
BACKGROUND: The study aims to describe the neurobehavioral and psychopathological disorders in road crash victims with cerebral lesions compared with multiple trauma sufferers with no brain damage. METHODS: This study compares the neuropsychological and psychopathological developments of two groups of road crash victims (25 severe brain injuries (SBI) and 25 multiple traumas (MULT)) on the basis of the Neurobehavioral Scale, the SCL 90-R and the State/Trait Anxiety Scale. RESULTS: On the basis of the Neurobehavioral Scale, it was clear that the SBI patients suffered from significantly more disorders of type factor 1 (self-appraisal and flexible thinking), factor II (withdrawal), factor III …
Multi-variate analysis predicts clinical outcome 30 days after middle cerebral artery infarction
2000
BACKGROUND AND PURPOSE: To evaluate the functional prognostic value of proton magnetic resonance spectroscopy performed within the 5 days of an infarction of the middle cerebral artery territory, compared with previously demonstrated prognostic factors. METHODS: Proton magnetic resonance spectroscopy was performed on 77 consecutive non-comatosed patients during the acute stage of middle cerebral artery infarction. The functional status was determined for each patient via the Orgogozo score. Proton magnetic resonance spectroscopic data were acquired in the infarction and in contra-lateral normal tissue and the results were expressed as metabolite ratios. Correlations were evaluated between t…
Cross-Talk Correction Method for Knee Kinematics in Gait Analysis Using Principal Component Analysis (PCA): A New Proposal
2014
International audience; Background: In 3D gait analysis, the knee joint is usually described by the Eulerian way. It consists in breaking down the motion between the articulating bones of the knee into three rotations around three axes: flexion/extension, abduction/adduction and internal/external rotation. However, the definition of these axes is prone to error, such as the "cross-talk'' effect, due to difficult positioning of anatomical landmarks. This paper proposes a correction method, principal component analysis (PCA), based on an objective kinematic criterion for standardization, in order to improve knee joint kinematic analysis. Methods: The method was applied to the 3D gait data of …
