Box-and-whisker change plots and cumulative line plots as a function of NP versus preserved (P) baseline distal extremity motor function. The overlaid line plots show the cumulative change (right y axis) observed across the trial (NP, black-filled, yellow circle; P: yellow-filled, black circle; n = 12 independent participants). For both c and d, boxes depict the median (horizontal line) within quartiles 1-3 (bounds of box). Whiskers extend to minimum and maximum values. Blue circles represent individual participant data points, while the blue 'X' depicts the average. a As described in the text, the DBS + rehab phase was a minimum of 4 months but extended up to 8 months for participants who showed ongoing improvement. As such, the '+1' time point reflects the measurement taken 1 month after DBS was turned OFF regardless of the DBS + rehab phase duration. The timing of all subsequent follow-up assessments was re-indexed to the final month of DBS + rehab.
