Modified Ashworth Scale (MAS) and First swing angle (FSA) values. A MAS scores obtained on Day 1 for the right (white bars) and left (black bars) leg for individuals in the SCI group. The FSA values for each participant are indicated by the blue and cyan circles on each side, respectively. The dotted gray lines represents the minimum FSA value obtained in control individuals. The graphs show the relationship between MAS scores and FSA values on Day 1 (orange dots) and Day 2 (black dots) using the optical tracking system (OTS) (B) and the IMU-based system (IMU) (C). The abscissa shows the FSA values in degrees and the ordinate shows the MAS scores. Each dot represents the average FSA value and MAS scores from a single limb. The dotted line indicate the least square linear regression between the MAS and FSA values on each day
