Koster et al. - Balance training in older adults enhances feedback control after perturbations - data & code

Data & code for: Balance training in older adults enhances feedback control after perturbations R A J Koster, L Alizadehsaravi, W Muijres, S M Bruijn, N Dominici, J H van Dieen This folder contains two subfolders: Code & Data. The folder Code contains the MATLAB scripts used to analyse the data contained within the folder Data. Scripts/ · RK_Analysis_Kinematics.m: This is the main script used to analyse the kinematics. Running it will compute the kinematic parameters investigated in the paper and contrast them between conditions. Visualisations of these as well as the statistical results will be stored in the newly created folder /Data/Processed/Figures/Kinematics/ · RK_Analysis_Synergies.m: This is the main script used to analyse the EMG activity. Running it will compute the synergies from the EMGs and contrast them between conditions. Visualisations of these as well as the statistical results will be stored in the newly created folder /Data/Processed/Figures/Synergies/ · Subfunctions/: This folder contains all scripts used within the two main scripts. These scripts are subdivided into 3 folders (General/, Kinematics analysis/, Synergy analysis/) based on which part of the analysis they belong to. o General/spmi1d/: The external toolbox used to perform the statistics. o Kinematics analysis/=VU 3D model=/: the VU 3D model used to compute kinematic parameters from the trajectories of individual body segments. Data/ · EMG/: Contains the raw EMG data for each participant & recording. · Excel sheets/: Contains participant & recording information sheets. This is used to determine on which leg the participant was standing. · PT/: Contains information about the rotating platform the participants were standing on for every recording. This is used to determine perturbation onset and direction. · Trajectory/: Contains the trajectories of the participant’s body segments during the recordings. · Processed/: (This folder is not there initially, but it is added by the 2 main codes) Will contain the kinematic parameters and synergy weights & activation patterns for every condition and participant after they are computed. This folder is also where the results from the analysis will be stored. o Figures/: For kinematics & synergies separately, will contain figures displaying the parameters and the statistical results. The ‘Stats – X – Y.tiff’ figure files display the ANOVA and post hoc test results. If statistical differences are found, their p-values are reported in the title of the individual plots. (Note that if there is no p-value reported it means no p-value exists as subthreshold results do not generate p-values in this type of analysis)
