目的：分析双膝骨性关节炎（osteoarthritis，OA）患者在步行周期中支撑相时足底各区域压力变化与正常健康人的差异，为疾病状态下的足底压力变化特征提供量化依据。
方法：选取2016年1月—2018年12月于河北省沧州中西医结合医院就诊的30例双侧膝关节炎的患者以及30例健康正常人为研究对象，采用Foot Scan测量系统采集患者及正常人足底7个区域的数据，选择各区域开始触地时刻、结束触地时刻，以及触地（受力）时间比作为主要参数进行统计分析。
结果：正常健康组相较于双KOA组，开始触地时刻左足足底M1区（P<0.01）、M2区（P<0.05）较晚，右足足底M1区、M2区、M3区、M4区（P<0.01）较晚；结束触地时刻，左足足底M3区（P<0.05）、M4区、M5区、HM区、HL区（P<0.01）较早，右足足底M3区、M4区较早（P<0.05）、HM区、HL区较早（P<0.01）；触地时间比，左足足底M2区、M3区、M4区、M5区、HM区、HL区较短（P<0.01），右足足底M1区、M2区、M3区、M4区、HM区、HL区较短（P<0.01）。双KOA患者左右足比较，开始接触地面时刻无差异，左足结束触地时刻M4、M5区较右足晚（P<0.05），触地时间百分比M5区较右足高（P<0.01）。
结论：①双KOA患者左右足受力不均衡，主要表现在M4、M5结束触地时刻左足较右足晚。②双KOA患者足底各区域受力时间分布具有特征性，足底各区域触地（受力）时间百分比左右足高于正常健康人群，M3、M4区触地（受力）时间延时最长。 |

| Abstract
Objective: To analyze the changes of plantar pressure between patients with bilateral knee osteoarthritis(OA) and normal controls during walking cycle, and provide quantitative evidence for the changes of plantar pressure in patients with osteoarthritis of both knees.
Method：From January 2016 to December 2018, 30 patients with bilateral knee arthritis and 30 healthy controls were selected from Cangzhou Integrated Hospital of traditional chinese and Western Medicine in Hebei Province. The Foot Scan measurement system was used to collect the data of 7 areas of the foot of patients and normal people. The time of starting contact, the time of ending contact and the time of touching the ground were selected as the main parameters for statistical analysis.
Result：Compared with the double KOA group, the left plantar M1 area and M2 area were later, and the right plantar M1 area, M2 area, M3 area and M4 area were later (P<0.01) at the beginning of touching the ground in the normal health group than in the double knee osteoarthritis group (P<0.01), and in the right plantar M1 area, M2 area, M3 area and M4 area (P<0.01). At the end of ground contact, the left plantar M3 area (P<0.05), M4 area, M5 area, HM area, HL area (P<0.01), right plantar M3 area, M4 area (P<0.05), HM area and HL area were earlier (P<0.01). The contact time was shorter in the left plantar M2, M3, M4, M5, HM and HL regions, and shorter in the right plantar M1, M2, M3, M4, HM and HL regions (P<0.05), and the contact time was shorter in the left plantar M2, M3, M4, M4 and M5 areas. There was no significant difference in the beginning of contact between the left and right feet. The M4 and M5 areas of the left foot were later than those of the right foot at the end of the contact time (P<0.05), and the percentage of contact time in the M5 area was higher than that of the right foot (P<0.01).
Conclusion：①The force on the left and right feet of patients with double KOA is uneven. The main manifestation is that the left foot is later than the right foot at the end of M4 and M5. ②The distribution of stress time in each area of foot in patients with double KOA was characteristic.The percentage of contact time in each area of foot was higher than that in normal healthy people, and the delay of contact time in M3 and M4 areas was the longest. |
