Central cord syndrome (CCS) is considered the most common incomplete
spinal cord injury (SCI). Independent ambulation was achieved in 87-97% in young
patients with CCS but no gait analysis studies have been reported before in such
pathology. The aim of this study was to analyze the gait characteristics of
subjects with CCS and to compare the findings with a healthy age, sex and
anthropomorphically matched control group (CG), walking both at a self-selected
speed and at the same speed. METHODS: Twelve CCS patients and a CG of twenty
subjects were analyzed. Kinematic data were obtained using a three-dimensional
motion analysis system with two scanner units. The CG were asked to walk at two
different speeds, at a self-selected speed and at a slower one, similar to the
mean gait speed previously registered in the CCS patient group. Temporal, spatial
variables and kinematic variables (maximum and minimum lower limb joint angles
throughout the gait cycle in each plane, along with the gait cycle instants of
occurrence and the joint range of motion - ROM) were compared between the two
groups walking at similar speeds. RESULTS: The kinematic parameters were compared
when both groups walked at a similar speed, given that there was a significant
difference in the self-selected speeds (p < 0.05). Hip abduction and knee flexion
at initial contact, as well as minimal knee flexion at stance, were larger in the
CCS group (p < 0.05). However, the range of knee and ankle motion in the sagittal
plane was greater in the CG group (p < 0.05). The maximal ankle plantar-flexion
values in stance phase and at toe off were larger in the CG (p < 0.05).
CONCLUSIONS: The gait pattern of CCS patients showed a decrease of knee and ankle
sagittal ROM during level walking and an increase in hip abduction to increase
base of support. The findings of this study help to improve the understanding how
CCS affects gait changes in the lower limbs
