膝骨关节炎对老年女性步态以及肌电活动的影响
作者:蒋磊 李宁 夏美燕 张忠兴 程新保

摘要:

于2018年11—12月在安徽医科大学第一附属医院康复科招募≥65岁女性膝骨关节炎患者。同期在社区招募≥65岁健康女性,各20名。检测结果显示,膝骨关节炎组在行走触地时,膝关节的触地角度更屈曲(P=0.040),在支撑期膝关节的最小角度会增加(P=0.008);髋和踝关节在支撑期的最大屈曲角度与对照组差异无统计学意义(P>0.05)。在支撑期,膝骨关节炎组胫骨前肌积分肌电低于对照组(P=0.023)。膝骨关节炎会改变老年女性的步态以及肌电活动表现,尤对下肢膝关节的影响最大。

Abstract:

From November to December of 2018, twenty 65-year-old or older women patients with knee osteoarthritis were recruited from the Department of Physical Therapy, the First Affiliated Hospital of Anhui Medical University. Meanwhile, twenty healthy 65-year-old or older women were recruited from the local community. The results showed that the knee contact angle of the patient group was more flexed (P=0.040), and the minimum angle of the knee joint increased (P=0.008) during the stance period compared to the healthy group. However, there was no significant difference in the maximum contact angle between the angle of hip and ankle joints. In addition, the tibialis anterior muscle of the patients was significantly smaller than the healthy group (P=0.023). Therefore, knee osteoarthritis could change the gait and muscle activity of older women, especially the knee joint.
