Structured modulations in high-density EMG patterns from a single muscle enable simultaneous control of natural and extra degrees of freedom - Processed data

MATLAB file containing all the processed data from the study.ResultAngle = Angles between e(t) and eref for each subject and each condition (1 are trials with a 0° target orientation and 2 are trials with a 45° target orientation). Those data are shown Figure 7B. ResultAngleForceControl = Angles between the mean HDsEMG patterns of pairs of trials, averaged across all pairs of each subject in each one of three conditions: i) trials with the same target position but differing in force amplitudes (orange), ii) trials with different target positions but with the same force amplitude (yellow) and iii) repeated trials with the same target position and force amplitude (purple). Those data are shown Figure 6. ResultAngleHoldingTask = The mean angle between e(t) and eref computed during the final 15 seconds of each sustained target in the Holding task for each participant. In the column “eref”, 0 refers to value calculated using an eref independent of the target position (as used during the experiment) and 1 to value calculated with an eref dependent on the target position. In the column “Contraction”, each number refers to the corresponding target. Those data are shown Figure 8C. ResultDerivative = The time derivative of SuDoF performance between 15° and 25° (Column “Angle” shows 20) and between 35° and 45° (Column “Angle” shows 40) for each participant. ResultForcePerformance = Normalized error between target position and cursor position (Force performance) for each participant and each condition (0 are trials during Force control Task, 1 are trials with a 0° target orientation and 2 are trials with a 45° target orientation). Those data are shown Figure 4A. ResultForceXY = Horizontal force (affecting cursor position) during the Force and SuDoF control task for each participant and each condition (1 are trials with a 0° target orientation and 2 are trials with a 45° target orientation). Those data are shown Figure 5A. Result ForceZ = Vertical force (not affecting cursor position), during the Force and SuDoF control task for each participant and each condition (1 are trials with a 0° target orientation and 2 are trials with a 45° target orientation). Those data are shown Figure 5B. ResultHoldingPerformance = Percentage of the one-second holding period in which the cursor was successfully maintained within the target (Holding performance) for each participant and each condition (0 are trials during Force control Task, 1 are trials with a 0° target orientation and 2 are trials with a 45° target orientation). Those data are shown Figure 4D. ResultNorm = Norm of e(t) for each subject and each condition (1 are trials with a 0° target orientation and 2 are trials with a 45° target orientation). Those data are shown Figure 7A. ResultNormHoldingTask = Average norm of e(t) during the final 15 seconds of each sustained target in the Holding task for each participant. In the column “eref”, 0 refers to value calculated using an eref independent of the target position (as used during the experiment) and 1 to value calculated with an eref dependent on the target position. In the column “Contraction”, each number refers to the corresponding target. Those data are shown Figure 8B. ResultSuDoFHoldingTask = The mean Distance value during the final 15 seconds of each sustained target in the Holding task for each participant. In the column “eref”, 0 refers to value calculated using an eref independent of the target position (as used during the experiment) and 1 to value calculated with an eref dependent on the target position. In the column “Contraction”, each number refers to the corresponding target. Those data are shown Figure 8A. ResutSuDoFPerformance = Normalized error between target orientation and cursor orientation (SuDoF performance) for each participant and each condition (0 are trials during Force control Task, 1 are trials with a 0° target orientation and 2 are trials with a 45° target orientation). Those data are shown Figure 4B. ResultTorqueY = Torque around the Y-axis (associated to wrist supination or pronation), during the Force and SuDoF control task for each participant and each condition (1 are trials with a 0° target orientation and 2 are trials with a 45° target orientation). Those data are shown Figure 5C. ResultTotalPerformance = Normalized error combining both the position and orientation errors (Total performance) for each participant and each condition (0 are trials during Force control Task, 1 are trials with a 0° target orientation and 2 are trials with a 45° target orientation). Those data are shown Figure 4C.
