早期不对称踝关节骨性关节炎对中老年人步态及下肢生物力学的影响
Effects of Early Asymmetric Ankle Osteoarthritis on Gait and Lower-Limb Biomechanics in Middle-Aged and Older Adults
摘要
Abstract
Objective:To investigate the effects of early asymmetric ankle osteoarthritis(AOA)on bilateral gait patterns and lower-limb biomechanics in middle-aged and older adults using three-dimensional gait analysis.Methods:Ninety-eight patients with early asymmetric AOA were recruited as the AOA group,and 85 age-and sex-matched healthy adults without recent lower-limb musculoskeletal disorders were included as controls.Collect baseline information from all participants.Spatiotemporal,kinematic,and kinetic parameters during walking were collected using the SMART-DX 400 three-dimensional gait analysis system.Gait parameters were calculated with BTS-SmartClinic software,and bilateral differences between groups were compared.Results:Compared with the control group,the AOA group showed increased stance phase,double-support phase,and peak hip flexion angle,while swing phase,step length,peak knee extension,ankle dorsiflexion,ankle plantarflexion,the second peak of vertical ground reaction force(V-GRF),and peak ankle plantarflexion moment were significantly reduced(P<0.05).Changes were more pronounced in the affected limb(AFL),which also demonstrated significantly reduced single-support phase,peak hip extension angle,and the first peak of V-GRF.Conversely,the non-affected limb(NAL)exhibited an increased first peak of V-GRF.In addition,the AOA group as a whole was characterized by a reduced cadence(P<0.05).Conclusion:Early asymmetric AOA induces bilateral biomechanical adaptations in middle-aged and older adults to relieve pain and maintain stability.These findings provide a biomechanical basis for early gait intervention in AOA and highlight the importance of bilateral rehabilitation strategies to prevent secondary injuries.关键词
