Abstract

This study aims to validate a commercially available inertial sensor based motion capture system, Xsens MVN BIOMECH using its native protocols, against a camera-based motion capture system for the measurement of joint angular kinematics. Performance was evaluated by comparing waveform similarity using range of motion, mean error and a new formulation of the coefficient of multiple correlation (CMC). Three dimensional joint angles of the lower limbs were determined for ten healthy subjects while they performed three daily activities: level walking, stair ascent, and stair descent. Under all three walking conditions, the Xsens system most accurately determined the flexion/extension joint angle (CMC > 0.96) for all joints. The joint angle measurements associated with the other two joint axes had lower correlation including complex CMC values. The poor correlation in the other two joint axes is most likely due to differences in the anatomical frame definition of limb segments used by the Xsens and Optotrak systems. Implementation of a protocol to align these two systems is necessary when comparing joint angle waveforms measured by the Xsens and other motion capture systems.

  • The estimated marker locations and subsequent model produced has previously been found to be a reliable and valid measure of joint kinematics during dynamic movements when in combination with a biomechanical model.

    “However, the estimated marker locations and subsequent model produced has previously been found to be a reliable and valid measure of joint kinematics during dynamic movements when in combination with a biomechanical model [19,20,21].”

    From The Effects of an Eight over Cricket Bowling Spell upon Pace Bowling Biomechanics and Performance within Different Delivery Lengths (2019) · cites this paper as [21]

    The Introduction (page not provided) says Xsens uses a biomechanical model to estimate 3D joint angles and describes the system as reliable. The Results (page not provided) show close agreement with camera-based measurements for flexion/extension during walking and stair use, but substantially lower agreement for the other joint axes. The paper does not validate estimated marker locations, so it does not support the claim as stated for joint kinematics generally. (LLM, conf=0.85)

  • The XSENS motion analysis system has previously been found to be a reliable and valid means of assessing joint angles in dynamic movements.

    “The XSENS motion analysis system has previously been found to be a reliable and valid means of assessing joint angles in dynamic movements [19,20,21].”

    From The Effects of an Eight over Cricket Bowling Spell upon Pace Bowling Biomechanics and Performance within Different Delivery Lengths (2019) · cites this paper as [21]

    The Introduction reports prior repeatability of Xsens joint-angle measurements during walking, and this study validates its flexion/extension measurements during walking and stair use. However, the Results and Discussion report substantially poorer agreement for joint angles on the other two axes. The claim is therefore too broad if it refers to joint angles generally across dynamic movements. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Knee intra-rater reliability was fair to excellent and inter-rater reliability varied across movements (good for walking ICC 0.4 to 0.74 and poor for jumping ICC ≤0.39).

    “Intra-rater reliability was fair to excellent and inter-rater reliability varied across movements performed (good for walking [ICC from 0.4 to 0.74] and poor for jumping [ICC ≤ 0.39] [45,53,59]).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
