Abstract

Background: Knee osteoarthritis (KOA) is characterised by altered gait mechanics, which can lead to significant functional impairments. This study aims to investigate plantar pressure distribution during walking and assess functional mobility in patients with early-stage KOA, providing insights for targeted therapeutic interventions.

Methods: Eighteen women with KOA were matched with 18 healthy controls for this study. We assessed plantar pressure distribution, relative phase durations during the stance phase, and performance on the Timed Up and Go (TUG) test. Independent sample t-tests were employed to identify group differences, with significance set at p < 0.05.

Results: Patients with KOA exhibited significantly lower maximum plantar pressure in the Toe 1 (p < 0.01), medial heel (p < 0.01), and lateral heel (p < 0.01) regions, while demonstrating higher pressure in the Metatarsal 4 (p < 0.01) and midfoot (p < 0.01) areas. Furthermore, KOA patients spent less time in the initial contact (p = 0.01), foot-flat (p < 0.01), and forefoot push-off (p = 0.03) phases but more time in the forefoot plantarflexion phase (p < 0.01). Additionally, KOA patients demonstrated longer TUG times (p < 0.01), indicating reduced functional mobility.

Conclusions: Early-stage KOA patients display distinct patterns of plantar pressure distribution and impaired functional mobility compared with healthy controls. These findings highlight the necessity for interventions aimed at addressing altered gait mechanics in KOA, which could help mitigate mobility limitations and enhance patient outcomes.

早期膝骨关节炎患者步态和功能活动时足底压力分布模式的比较研究。

背景：膝骨关节炎（KOA）的特点是步态力学改变，可导致显著的功能损伤。本研究旨在研究早期KOA患者行走时足底压力分布，并评估其功能活动能力，为有针对性的治疗干预提供见解。方法：18名KOA女性与18名健康对照者进行对照研究。我们评估了足底压力分布、站立阶段的相对相位持续时间，以及在Timed Up and Go （TUG）测试中的表现。采用独立样本t检验来确定组间差异，显著性设为p。结果：KOA患者足底最大压力显著降低1 (p)。结论：与健康对照相比，早期KOA患者足底压力分布和功能活动能力受损模式明显不同。这些发现强调了干预措施的必要性，旨在解决KOA中改变的步态力学，这可能有助于减轻活动限制并提高患者的预后。
