Individualized data for LEMS score (A), 10-m walking test (B), Timed Up and Go test (C) and Walking Index for Spinal Cord Injury II scale (D). Left panels show raw data at baseline (PRE), after the intervention (POST) and 1-month follow-up (FU). Right panels show the change from baseline at POST and at FU. Horizontal line of the right panels represents the “zero effect”. Brown circles represent the mean of the active transcutaneous spinal cord stimulation (tSCS) group and cyan squares represent the mean of the sham tSCS group. Filled in red represent the imputed value of the missing data of subjects lost during follow-up. Filled in grey represent the imputed data of subjects who were not able to finish the test.
