Spatiotemporal modulation of a common set of muscle synergies during unpredictable and predictable gait perturbations in older adults

Abstract

Instructions for the uploaded data: An explaination of the study sample, study protocol and the specific parameters can be found in the corresponding study: "Spatiotemporal modulation of a common set of muscle synergies during unpredictable and predictable gait perturbations in older adults" by Brüll et al., 2024 in the Journal of Experimental Biology.

Each of the 40 provided CSV-files includes the data of one specific parameter in long format: CS=cosine similarity COA=center of activity of the activation patterns of the muscle synergies FWHM=full width at half maximum of the activation patterns of the muscle synergies Syn1=weight acceptance synergy Syn2=propulsion synergy Syn3=early swing synergy Syn4=late swing synergy ap=condition that included anteroposterior perturbations ml=condition that included mediolateral perturbations

Each CSV-file includes the following 4 columns: subject=includes the specific ID number of the 63 included participants condition=includes one of the 4 different conditions (a combination of unpredictable/predictalbe and mediolateral/anteroposterior) cycles=includes one of the 12 consecutive gait cycles (1-3=unperturbed walking, 4=perturbation cycle, 5-12=recovery cycles) value=the specific parameter value for the respective combination of subject, condition and cycle
