Mechanical validation of whole bone composite femur models.
Composite synthetic models of the human femur have recently become commercially available as substitutes for cadaveric specimens. Their quick diffusion was justified by the advantages they offer as aExpand

Quantification of soft tissue artefact in motion analysis by combining 3D fluoroscopy and stereophotogrammetry: a study on two subjects.
BACKGROUND Soft tissue artefact is the most invalidating source of error in human motion analysis using optoelectronic stereophotogrammetry. It is caused by the erroneous assumption that markersExpand

Stabilometric parameters are affected by anthropometry and foot placement.
OBJECTIVE To recognize and quantify the influence of biomechanical factors, namely anthropometry and foot placement, on the more common measures of stabilometric performance, including new-generationExpand

Evaluation of Accelerometer-Based Fall Detection Algorithms on Real-World Falls
Despite extensive preventive efforts, falls continue to be a major source of morbidity and mortality among elderly. Real-time detection of falls and their urgent communication to a telecare centerExpand

A new formulation of the coefficient of multiple correlation to assess the similarity of waveforms measured synchronously by different motion analysis protocols.
Different 3D motion analysis protocols are currently available, but little is known regarding the level of similarity of their outcomes, e.g. whether a joint-angle waveform from one protocol can beExpand

Surface-marker cluster design criteria for 3-D bone movement reconstruction
When three-dimensional (3-D) human or animal movement is recorded using a photogrammetric system, bone-embedded frame positions and orientations are estimated from reconstructed surface markerExpand

Multiple anatomical landmark calibration for optimal bone pose estimation
Abstract Bone motion estimation by means of photogrammetric, non-invasive methods can be severely corrupted by experimental errors. The largest fraction of such errors is associated with the relativeExpand

Effects of hip joint centre mislocation on gait analysis results.
Methods to determine the hip joint centre (HJC) location are necessary in gait analysis. It has been demonstrated that the methods proposed in the literature involve large mislocation errors. TheExpand

Skin movement artefact assessment and compensation in the estimation of knee-joint kinematics.
In three dimensional (3-D) human movement analysis using close-range photogrammetry, surface marker clusters deform and rigidly move relative to the underlying bone. This introduces an importantExpand

An improved technique for the extraction of stochastic parameters from stabilograms.
An improved characterization of the dynamics of postural sway can provide a better understanding about the functional organization of the postural control system as well as a more robust tool forExpand
