FILE NAME : Data.mat
This file displays the center of pressure (COP), interference electromyography (Interference_EMG), motor units discharge rate (MU_Discharge_rate) and kinematics data for each participant, each task and each condition.
The center of pressure and kinematics data is organized according the following structure: Outcome.Task.Condition.
The interference electromyography and motor units discharge rate data is organized according the following structure: Outcome.Muscle.Task.Condition.
Muscle : GM, Gastrocemius Medialis; GL, Gastrocnemius Lateralis; SOL, Soleus; TA, Tibialis Anterior.
Each matrix contains 20 rows corresponding to each participant.
For the motor units discharge rate data, the matrix can contain several columns corresponding to the different motor units identified and tracked across conditions. Some rows are empty as we were not able to identify and tracked motor units across conditions for these participants.
For the soleus interference electromyography, the participant 16 is missing. We excluded this participant due to noisy signal and artifacts. This subject is not considered in the interference electromyography analysis. Similarly, the kinematics data for the participant 2 and 18 are missing as we cannot analyze the data due to technical issue.

FILE NAME : PXX.mat
These files contain raw electromyography data for each participant, each muscle, each task and each condition. In addition, these files displays the motor unit identified and manually edited (RH) using the MUedit software (Avrillon et al., 2024).
Each file is organized according the following structure: [Participant_number].[task].[condition].mat
These files can be opened with Matlab (Mathworks) or the MUedit software.
Subject_number: 1 to 20
Task: Standing with eyes open; standing with eyes closed; standing on a foam surface with eyes closed; standing only on a single (dominant) leg with eyes open.

Conditions: Control, without the passive ankle exoskeleton; Exoskeleton, with passive ankle exoskeleton assistance.
VARIABLES:
- signal: contains all the data and especially the raw electromyography signal (ParticipantNumber.Task.Condition.signal.data).
- parameters: contains all the parameters of the decomposition.
- edition: contains the edited pulse train and discharge times of the motor unit identified.
Each signal displays 6 matrix corresponding to the 6 matrix of electrodes. Matrix 1 and 2 correspond to the tibialis anterior, matrix 3 corresponds to the gastrocnemius medialis, matrix 4 corresponds to the gastrocnemius lateralis and matrix 5 and 6 correspond to the soleus. For the participant 2 and 3, due to technical issues, we were forced to use only 5 matrix of electrodes. Therefore, for these two participants, matrix 1 corresponds to the tibialis anterior, matrix 2 corresponds to the gastrocnemius medialis, matrix 3 corresponds to the gastrocnemius lateralis and matrix 4 and 5 corresponds to the soleus.
All the different variables present in these files are described in the user manual of the MUedit software.
