TL;DR: Analysis on the effect of hip movement amplitude revealed that a reduction of the amplitude does not improve the HJC location accuracy despite a decrease of the artefact amplitude, and larger errors were found in the subject with larger soft tissue artefacts.

TL;DR: The females' ability to implement a more effective attenuation allowed them to reach head accelerations equivalent to those of the males despite higher pelvis accelerations, which should always be considered when upper body kinematics is used for clinical assessment.

TL;DR: The proposed method provides an estimate of the STD vector in a bone-embedded frame that constitutes valuable information when aiming at optimal marker placement and is an indispensable prerequisite for bone pose estimator design and assessment.

TL;DR: To contribute to their auspice and to pursue the relevant scientific objectives, joint kinematics must be estimated with a higher resolution than presently available.
Abstract: Recently Freeman e Pinskerova stated: “It may be hoped that the next few years will see a resolution to the question: how does the healthy and diseased knee move in the activities of daily life?”. To contribute to their auspice and to pursue the relevant scientific objectives, joint kinematics must be estimated with a higher resolution than presently available. To this purpose, the following issues must be tackled: 1) optimal estimation of the instantaneous pose of bones in a laboratory system of reference during the execution a physical exercise using the instantaneous position or pose of skin markers; 2) optimal estimation of the subject-specific bone morphology and determination of the relevant anatomical axes.

TL;DR: This paper aims at reviewing the experience maturated over the past decade by this group in the framework of the VAMA (Italian acronym for “evaluation of motor ability in the elderly”) project, to devise quantitative methods for assessing the locomotor functional limitation of a given individual.
Abstract: This paper aims at reviewing the experience maturated over the past decade by this group in the framework of the VAMA (Italian acronym for “evaluation of motor ability in the elderly”) project. The objective of that research programme was to devise quantitative methods for assessing the locomotor functional limitation of a given individual and, as a further step, for investigating the relationship between relevant impairments and disability. This was accomplished through the biomechanical analysis of a battery of selected motor tasks as executed by groups of elderly individuals. The attainment of this objective entailed the following methodological steps: increasing the resolution with which the human movement is observed; enhancing the information contained in movement-related data by applying models of the musculoskeletal system; extracting the relevant information by using specific methods of knowledge discovery from databases.
