Observation of Dynamic Plantar Pressure in Hemiplegic Patients after Stroke during the Recovery Period

目的：观察恢复期脑卒中偏瘫患者行走时，双侧下肢足底压力动态分布的特征。方法：纳入2023年5月至2024年5月在安徽医科大学第二附属医院康复医学科住院的脑卒中恢复期患者。通过足底压力分析，比较双侧下肢足底压力占比、压力面积占比、压力Ad值。结果：与健侧相比，患者患侧足底T1、M1、M2区压力占比低于健侧，差异有统计学意义(P Objective: To observe the characteristics of the dynamic distribution of plantar pressure in bilateral lower limbs of hemiplegic patients with stroke during the recovery period when walking. Methods: Recovering stroke patients who were hospitalized in the Department of Rehabilitation Medicine of the Second Affiliated Hospital of Anhui Medical University from May 2023 to May 2024 were included. By plantar pressure analysis, the plantar pressure percentage, pressure area percentage, and pressure Ad value of bilateral lower limbs were compared. Results: Compared with the healthy side, the pressure percentage of plantar T1, M1, and M2 areas on the affected side of the patients was lower than that on the healthy side, and the difference was statistically significant (P < 0.05), and the pressure percentage of plantar M5 and LH areas on the affected side was higher than that on the healthy side, and the difference was statistically significant (P < 0.05). Compared with the healthy side, the pressure area of the plantar M5 region of the affected side was larger, and the pressure area of the MH and LH regions was smaller, and the difference was statistically significant (P < 0.05). The percentage of Ad value of whole foot pressure on the healthy side was (56.55 ± 3.8)%, and the percentage of Ad value of whole foot pressure on the affected side was (43.45 ± 3.8)%, and the difference was statistically significant (P < 0.001). Conclusion: When walking, the weight bearing of the lower limbs of recovering stroke patients was biased toward the healthy side, and the weight bearing of the lower limbs of the affected side was shifted to the lateral side of the forefoot and the lateral side of the heel, and the area of the heel under pressure was reduced.
