Effects of impairment severity and responder status on repetitions and abnormal co-activation. A Total number of repetitions vs. baseline speed for each participant (square). Horizontal dashed line represents the theoretical expected number of repetitions over 6 days and vertical dashed line divides participants into limited and full community ambulators. B Co-activation (R) between RF and AM during 6-day MINT conditioning for full and limited community ambulators. C Number of repetitions vs. gait speed change (day 1 to day 6) due to training. Horizontal dashed line is the same as in A; vertical dashed line shows MCID of 0.1 m/s used to divide participants to responders and non-responders. D Co-activation between RF and AM for responder and non-responder groups. (* indicates statistical significance with p < 0.05)
