Figure 1—source data 1. The Matlab data file containing source data related to Figure 1.The variables ‘Group1_PowChange’ and ‘Group2_PowChange’ contain data about average movement-related power changes between 1 Hz and 90 Hz in the two STN groups, respectively. The variables ‘Group1_ Force_DifSRE’, ‘Group1_ FY_DifSRE’, ‘Group2_ Force_DifSRE’, ‘Group2_ FY_DifSRE’ contain data about the average force trajectories and force yank trajectories at each effort range for each STN in Group one and Group 2. The variables ‘Group1_Corr_FrcSRE’, ‘Group1_Corr_FySRE’, ‘Group2_ Corr_FrcSRE’’, ‘Group2_Corr_FySRE’ contain correlation coefficients between stable force or peak force yank and self-rated effort for each STN in the two groups.
