Joint angle measures at specific points in the gait cycle. A: Joint angle values for cycle minimum, cycle maximum and cycle range for all measured joints for both sham injury and incomplete spinal cord injury (iSCI) groups. Large increases were noted in all measures at the ankle, particularly at cycle max (overextension) and in cycle range when comparing iSCI to sham animals. The range of motion and cycle max for the knee were decreased in iSCI animals when compared with sham. Mean ± SEM degrees for 5 rats per group. (*) indicates p<0.05. B: Joint angle values for swing phase minimum, stance phase maximum and subcycle range for all measured joints for both sham injury and incomplete spinal cord injury (iSCI) groups. Large changes were noted in all measures at the ankle, particularly in stance max (overextension) and subcycle range as well as two measures at the knee. No significant changes were noted at the hip. Mean ± SEM degrees for 5 rats per group. (*) indicates p<0.05. C: Joint angle values for lift-off and touchdown for all measured joints for both sham injury and incomplete spinal cord injury (iSCI) groups. In the sham animals, knee angles values at lift-off and touchdown are very different from one another and ankle angle values are very similar to one another. For iSCI animals, the opposite is true. Knee values become similar to one another and ankle values become vastly different. Mean ± SEM degrees for 5 rats per group. (*) indicates p<0.05.
