A4_Calculate_RotationalAcceleration.m Apr 1, 2022 - Postprocessing Code for 'Falling Heads': investigating reflexive responses to head-neck perturbations Plain Text - 11.5 KB - MD5: b19a9e08a1d123629d5d6fabb694bfd0 This script calculates and saves the rotational acceleration of the centre of gravity (head). It creates two figures as output (for the supine and prone case) and saves the calculated data as "rotationalpeakacc.mat" file. Furthermore, it produces the second half of the latex tables Table 1 and Table 3 (rotational peak accelerations) of the paper.
A5_CalculateHeadmassAndMomentOfInertia.m Apr 1, 2022 - Postprocessing Code for 'Falling Heads': investigating reflexive responses to head-neck perturbations Plain Text - 2.2 KB - MD5: 5b3e153151e9134d235befda0b35b4fa This script calculates and saves the headmass and the moment of inertia of all participants based on their size and height according to description given in the paper (section 5.5.).
A6_Calculate_rx_ry.m Apr 1, 2022 - Postprocessing Code for 'Falling Heads': investigating reflexive responses to head-neck perturbations Plain Text - 1.8 KB - MD5: 14ca4b7af186ae1e00de1bde2a2abb13 This script calculates and saves the moment arms r_x and r_y of the headneck joint necessary to calculate the inverse dynamics.
A7_CalculateFxy.m Apr 1, 2022 - Postprocessing Code for 'Falling Heads': investigating reflexive responses to head-neck perturbations Plain Text - 1.8 KB - MD5: cc704a41c21473c7b3b934d153d9ddff This script calculates the force acting in the sagittal x-y plane on the rigid head-neck segment. The force in x-direction can be calculated according to equation (6) in the paper, the force in y-direction according to equation (7).
A8_CalculateMz.m Apr 1, 2022 - Postprocessing Code for 'Falling Heads': investigating reflexive responses to head-neck perturbations Plain Text - 2.0 KB - MD5: 2f77787aaa8c6be6aa1364c5ebb5b085 This script calculates the joint torque M_net exerted on the head-neck segment by the trunk segment at the connecting joint. This can be calculated according to equation (8) in the paper.
A9_PlotInvDynamikAnalysis.m Apr 1, 2022 - Postprocessing Code for 'Falling Heads': investigating reflexive responses to head-neck perturbations Plain Text - 14.3 KB - MD5: 1f1a395761378659a11f24f1943eefcd This script plots the results of the inverse dynamic analysis. With the current settings, it plots Fig (6). If you want to reproduce Figure 7, you need to switch the "caseflagreproduce_figure7_exptraj" to on, and the other caseflagreproduces off; same applied to reproduce figure S1 of the supplementary material.
kinematic_analysis_expdata_chinmarker.mat Apr 1, 2022 - Postprocessing Code for 'Falling Heads': investigating reflexive responses to head-neck perturbations MATLAB Data - 216.8 KB - MD5: 16b9c0a5b44fbb1f1134d2e70cdd779c This data file is needed to run A0_LoadTrajectories and contains the trajectory data of the chin marker.
