Level walking in adults with and without Developmental Coordination Disorder: An analysis of movement variability

“…In this study we used one of the simplest kinematic methods, a single marker placed on the sacrum, to approximate CoM motion. This single marker method has been shown to be an effective, inexpensive, and reasonably accurate estimate in the vertical direction at slower walking speeds (Gard, Miff, & Kuo, 2004;Saini, Kerrigan, Thirunarayan, & Duff-Raffaele, 1998;Thirunarayan, Kerrigan, Rabuffetti, Croce, & Saini, 1996), as well as in the medio-lateral and frontal direction to analyze simple movement activities without trunk flexion or limb bending (Mapelli et al, 2014). For each step sacral root mean squared velocity (ms -1 ) and acceleration (ms -2 ) was calculated over the three axes of movement:…”

Stair Ascent and Descent in Assessing Donor-Site Morbidity Following Osteocutaneous Free Fibula Transfer: A Preliminary Study

“…In particular, we recently devised a method including 10 body segments, as described in detail by Mapelli et al 27 . In brief, the 10 segments (head and neck, trunk, arms, forearms, thighs, and legs) are defined by a cluster of 14 markers (a subset of those recorded in the current study, Fig In particular, anterior-posterior (relative to the center of the pelvis) and lateral-lateral displacements of the CoM during the task were taken into account.…”

“…We analyzed only a 3-step staircase because of laboratory dimensions: during motion analysis, all the body landmarks must be seen by two cameras at least to ensure the 3D reconstruction of landmarks' trajectories 25,27 . The system cannot be used outdoor, and higher staircases cannot be fit inside the working volume of the motion capture system.…”

An Artificial Neural Network Approach for Predicting Kinematics in Handball Throws

“…Additionally, the maximum change in COM velocity is considered an important parameter that is potentially related to performance [5]. The force of COM considers relevant information that exists while performing sport techniques [6].…”
