Abstract: BACKGROUND: Degenerative lumbar spondylolisthesis is a common spinal degenerative disorder among older adults, often accompanied by spinopelvic sagittal imbalance. The characteristics of plantar pressure and balance function in these patients have not been fully elucidated.
OBJECTIVE: To investigate the spinopelvic sagittal parameters and plantar pressure characteristics in older adults with degenerative lumbar spondylolisthesis, to provide a reference for early diagnosis and the development of rehabilitation plans in older adults with degenerative lumbar spondylolisthesis.
METHODS: A total of 33 patients with degenerative lumbar spondylolisthesis (degenerative lumbar spondylolisthesis group) and 35 healthy older adults (control group) were enrolled. Lateral radiographs of the whole spine were obtained to measure spinopelvic sagittal parameters. Plantar pressure distribution, including the pressure ratio, peak pressure in eight regions of interest, and center of pressure trajectory parameters, was collected using a plantar pressure analysis system. The differences in spinal-pelvic sagittal parameters, center of pressure trajectory, and plantar pressure parameters between the two groups were compared and analyzed.
RESULTS AND CONCLUSION: (1) Compared with the control group, the degenerative lumbar spondylolisthesis group showed significant increases in pelvic incidence, pelvic tilt, sacral slope, and lumbar lordosis (P < 0.05). (2) Compared with the control group, the degenerative lumbar spondylolisthesis group exhibited a significant increase in the pressure percentage under the left forefoot and the forefoot overall (P < 0.05), while the pressure percentage under the left hindfoot and the hindfoot overall decreased significantly (P < 0.05). (3) Compared with the control group, peak pressure under the left first metatarsal bone was significantly higher in the degenerative lumbar spondylolisthesis group (P < 0.05), whereas peak pressure under the right fifth metatarsal and the left medial arch was significantly lower (P < 0.05). (4) Compared with the control group, under eyes-open and eyes-closed conditions, the degenerative lumbar spondylolisthesis group demonstrated a significant increase in center of pressure trajectory length, 95% confidence ellipse area, and the average center of pressure displacement in the anteroposterior (X) and mediolateral (Y) directions (P < 0.05). (5) It is indicated that older adults with degenerative lumbar spondylolisthesis exhibit characteristic changes in spinopelvic sagittal alignment, notably increased pelvic incidence, pelvic tilt, sacral slope, and lumbar lordosis. Their plantar pressure distribution shifts anteriorly, with increased forefoot pressure and decreased hindfoot pressure, indicating an imbalance in foot mechanical symmetry and disruption of the normal tripod support structure. These alterations are accompanied by reduced center of pressure stability, reflecting impaired balance function in degenerative lumbar spondylolisthesis patients.
