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

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 similarityCOA=center of activity of the activation patterns of the muscle synergiesFWHM=full width at half maximum of the activation patterns of the muscle synergiesSyn1=weight acceptance synergySyn2=propulsion synergySyn3=early swing synergySyn4=late swing synergyap=condition that included anteroposterior perturbationsml=condition that included mediolateral perturbations

Each CSV-file includes the following 4 columns:

subject=includes the specific ID number of the 63 included participantscondition=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
