Abstract

In the context of clinical gait analysis, experimental and analytical problems associated with the assessment of joint kinematics and kinetics are dealt with. Reference is made to the 3-D analysis of the lower limb during walking carried out using a stereometric optoelectronic system and forceplate. Experiments are described aiming at the determination of both instrumental inaccuracies and artifacts due to the movement of skin markers with respect to the underlying bone.

    Citation Excerpt :

    Motion-capture techniques that are based on skin-mounted markers are prone to errors introduced by inaccurate and/or inconsistent marker placement and soft tissue artifacts (STA) [7]. The latter are considered as relative movements of the skin (and markers) to underlying bone [8,9] and presumably increase with higher amount of subcutaneous fat. These errors can have a considerable effect on achievable reliability.

    Citation Excerpt :

    A person entering a room is a very complicated process and consists of a series of delicate movements [52]. The acting force between door and the person, the acceleration and deceleration of the door and the person, and the flow field surrounding the door and the person are rapidly changing [52,53]. The driving forces of the door and the person, and the characteristic velocity of the fluid flow are difficult to obtain.

  • A novel method to replicate the kinematics of the carpus using a six degree-of-freedom robot

    2014, Journal of Biomechanics
    Citation Excerpt :

    Because the displacement accuracies of the Hexapod (Table 1) are orders of magnitude smaller than the RMS errors, we can assume that the vast majority of the error comes from the motion capture system. No markers were placed directly on soft tissues, therefore soft tissue artifacts, which usually make up for the majority of measurement error (Cappozzo, 1991; Leardini et al., 2005), should not be a factor. However, the surrounding tissues could have influenced the bone pin movement.
