摘要

Spinal deformities, including scoliosis and adult spinal deformity (ASD) and sagittal malalignment, lead to altered walking biomechanics. We aimed to investigate the correlation between spinopelvic angles and walking biomechanics in individuals with spinal deformities. We searched Four databases, including PubMed, Web of Science, Scopus, and Embase from their inception through 5th March 2025. Two reviewers extracted data and assessed the quality of evidence using Newcastle–Ottawa Scale. Correlation coefficients with 95% confidence intervals (CIs) were calculated using a random-effects model in MedCalc version 23.1.7. A total of 28 studies with 1376 participants were included. In scoliotic individuals, meta-analysis showed a significant correlation between static cobb° and pelvic obliquity during walking (p = 0.02, r = 0.314), (I2 = 0.00, p = 0.763), and a significant correlation between static cobb° and step width with moderate evidence (p < 0.001, r = −0.355), (I2 = 0.00, p = 0.796). In individuals with ASD, meta-analysis showed a significant correlation between sagittal vertical axis (SVA)° and speed during walking [p < 0.001, r = −0.609), (I2 = 62%, p = 0.104, CI(0–91)], between SVA RoM° and speed (p < 0.001, r = −0.433), (I2 = 0.00, p = 0.56), between dynamic pelvic tilt and speed showed significant results with moderate evidence (p < 0.001, r = −0.373), (I2 = 6%, p = 0.345), between SVA and gait deviation index (p < 0.001, r = −0.466), (I2 = 48%, p = 0.17), and SVA and dynamic pelvic tilt showed significant correlation with moderate evidence (p < 0.001, r = 0.496), (I2 = 0%, p = 0.88). In hyperkyphotic and lordotic individuals, there were limited evidence for correlation between angular kyphosis and maximum center-of-pressure (CoP) displacement in frontal (r = 0.182, p = 0.008) and sagittal plane (r = 0.438, p < 0.001). The lumbar lordosis° correlated with maximum CoP displacements in frontal (r = 0.265, p < 0.001) and sagittal planes (r = 0.999, p < 0.001) with limited evidence. This study reveals significant correlations between spinopelvic angles and walking biomechanics in spinal deformities, suggesting that gait assessment and potential correction strategies may be valuable components of comprehensive rehabilitation, depending on individual patient factors.
