Alterations in static plantar pressure distribution serve as important indicators of gait and balance impairments in individuals with Multiple Sclerosis (MS). In addition, the identification of altered patterns of plantar load distribution, along with restricted ankle dorsiflexion, may serve as early markers of postural instability and gait dysfunction in women with MS. : To assess differences in static plantar pressure, load distribution, and ankle dorsiflexion range of motion between women diagnosed with MS and women without the condition. : A cross-sectional observational study was conducted between April and December 2024. Women with MS were recruited from patient associations in the provinces of Alicante and Murcia, as well as from the neurology outpatient clinic at the Doctor Balmis University Hospital (Alicante, Spain). Static postural assessment was performed using the Neo-Plate pressure platform, which measured maximum and mean plantar pressure (kPa), load distribution (%), contact surface area (cm), and anterior-posterior weight distribution between the forefoot and rearfoot. The ankle dorsiflexion range of motion was assessed with a universal two-arm goniometer. All parameters were compared with those of a group of women without a diagnosis of MS. : Compared to women without MS, participants with MS showed a significantly greater load on the right forefoot (25.75% vs. 23.41%, = 0.021), and reduced load on the right (23.09% vs. 26.01%, = 0.004) and left rearfoot (26.60% vs. 30.85%, = 0.033). Total forefoot loading was significantly higher (52.33% vs. 46.40%, < 0.001), and rearfoot loading was lower (47.64% vs. 52.42%, = 0.006) in the MS group. Ankle dorsiflexion range of motion was also significantly reduced in women with MS, both with the knee flexed (5.95° ± 4.50 and 6.76° ± 4.69 vs. 15.45° ± 5.04 and 14.90° ± 5.43) and extended (2.69° ± 3.69 and 3.12° ± 3.83 vs. 8.17° ± 3.41 and 8.60° ± 3.31), with all differences reaching statistical significance ( < 0.001). : Women with MS present significant alterations in static plantar load distribution, with increased forefoot and decreased rearfoot loading, as well as markedly reduced ankle dorsiflexion, in comparison to women without the disease. These findings suggest the presence of postural imbalances associated with MS, potentially affecting functional stability and mobility.
静态足底压力分布的改变是多发性硬化症（MS）患者步态和平衡障碍的重要指标。此外，识别足底负荷分布的改变模式以及踝关节背屈受限，可能是MS女性患者姿势不稳和步态功能障碍的早期标志物。：评估确诊为MS的女性与未患该病的女性在静态足底压力、负荷分布和踝关节背屈活动范围方面的差异。：于2024年4月至12月进行了一项横断面观察性研究。MS女性患者从阿利坎特省和穆尔西亚省的患者协会以及巴尔米斯医生大学医院（西班牙阿利坎特）的神经科门诊招募。使用Neo-Plate压力平台进行静态姿势评估，该平台测量最大和平均足底压力（kPa）、负荷分布（%）、接触表面积（cm）以及前足和后足之间的前后重量分布。使用通用双臂测角仪评估踝关节背屈活动范围。将所有参数与一组未诊断为MS的女性的参数进行比较。：与未患MS的女性相比，MS患者右前足的负荷明显更大（25.75%对23.41%，=0.021），右后足（23.09%对26.01%，=0.004）和左后足（26.60%对30.85%，=0.033）的负荷降低。MS组前足总负荷明显更高（52.33%对46.40%，<0.001），后足负荷更低（47.64%对52.42%，=0.006）。MS女性患者的踝关节背屈活动范围也明显减小，无论是膝关节屈曲时（5.95°±4.50和6.76°±4.69对15.45°±5.04和14.90°±5.43）还是伸展时（2.69°±3.69和3.12°±3.83对8.17°±3.41和8.60°±3.31），所有差异均具有统计学意义（<0.001）。：与未患该病的女性相比，MS女性患者在静态足底负荷分布方面存在显著改变，前足负荷增加而后足负荷减少，同时踝关节背屈明显减小。这些发现表明存在与MS相关的姿势失衡，可能影响功能稳定性和移动性。
