目的 调查全膝关节置换术后患者的体力活动水平及其影响因素。

方法 根据纳入排除标准招募研究对象,采用方便抽样法,运用一般资料调查表、国际体力活动量问卷、体育活动自我调控问卷和美国特种外科医院膝关节评分量表进行调查。

结果 112名研究对象参与本研究,总平均体力活动量为(5 087.39±2 234.21),低、中、高强度的活动量分别为(1 612.89±340.89)、(1 009.31±818.23)、(267.76±49.89);体力活动的动机为(41.89±11.78),自主性动机得分为(29.18±8.87),外在调节得分为(6.59±2.01),内摄调节得分为(5.43±1.48);膝关节功能得分为(71.33±13.01);年龄、BMI、膝关节功能、体力活动动机、居住情况等均能影响体力活动水平(P<0.01)。

结论 全膝关节置换术后患者体力活动水平处于较低水平,年龄、BMI、膝关节功能、体力活动动机、居住情况等是体力活动水平的积极因素。

Objective To investigate the physical activity level and its influencing factors in patients after total knee arthroplasty.

Methods The subjects were recruited according to the inclusion and exclusion criteria by simple random sampling method, and "General data questionnaire", "International Physical Activity Questionnaire", "Regulation Questionnaire of Physical activity" and "hospital for Special surgery knee score" were adopted to investigate in this study.

Results A total of 112 patients participated in the study. The total average physical activity was (5 087.39±2 234.21), and the low, medium, and high intensity activities were (1 612.89±340.89), (1 009.31±818.23), (267.76±49.89) respectively. The motivation for physical activity was (41.89±11.78), of which the autonomic motivation score was (29.18±8.87), the external adjustment score was (6.59±2.01), the endoscopic adjustment score was (5.43±1.48). The knee joint function assessment score was (71.33±13.01). The age, BMI, knee joint function, physical activity motivation, condition of residence all affected physical activity level (P<0.01).

Conclusion The physical activity level of patients after total knee arthroplasty is low. Age, BMI, knee joint function, physical activity motivation, condition of residence are positive factors of physical activity level.
