| Objective: By observing the gait variability, symmetry, and coordination of patients with incomplete spinal cord injury, we can gain more comprehensive gait characteristics of patients with spinal cord injury. Methods: A total of 22 patients with incomplete spinal cord injury (observation group) and healthy subjects (control group) were selected, and the healthy subjects were divided into two subgroups (control group A and control group B) according to the normal walking speed and the matching speed of the patients. Gait test was performed by three-dimensional motion acquisition system and plantar pressure acquisition system. Gait variability, symmetry and coordination were represented by gait variation value, symmetry value and phase coordination index, and the differences of gait variability, symmetry and coordination and their correlation with walking function were compared among the three groups. Results: The variation values of step size, standing phase and stepping phase in observation group were higher than those in control group A. The symmetry values of step size, standing relative weighing value, stepping relative weighing value and phase coordination index in observation group were lower than those in control group, and the difference was statistically significant (P<0.05). In the observation group, gait variation, symmetry and phase coordination index were negatively correlated with walking ability after spinal cord injury. Multiple linear regression analysis showed that standing phase variance, standing relative scale and PCI had significantly negative effects on WISCI-II walk index, and PCI had significantly negative effects on FIM walking index. Conclusion: The gait variability, symmetry, and coordination of patients with incomplete spinal cord injury are lower than those of healthy individuals. When developing rehabilitation training plans for patients with incomplete spinal cord injury, we should consider the impact of gait variability, symmetry, and coordination on walking function. |
