We compared the metric properties of the University of California, Los Angeles (UCLA) activity scale, the Tegner score, and the Activity Rating Scale for assessment of activity levels in 105 patients undergoing THA (48 women; mean age, 63.4 years) and 100 patients undergoing TKA (61 women; mean age, 66.5 years). We assessed construct validity by correlating these scales with the International Physical Activity Questionnaire and different traditional patient self-reporting outcome measures. Test-retest reliability, feasibility, and floor and ceiling effects also were determined. The UCLA scale showed the strongest correlations with the other measures (r = -0.35 to 0.56 for THA; r = -0.55 to 0.23 for TKA) and was the only scale that discriminated between insufficiently and sufficiently active patients undergoing THA and TKA. The UCLA scale had the best reliability, provided the highest completion rate, and showed no floor effects. It seems to be the most appropriate scale for assessment of physical activity levels in patients undergoing total joint arthroplasty.

我们比较了加利福尼亚大学洛杉矶分校(UCLA)活动量表、泰格纳评分和活动评级量表在105例行全髋关节置换术(THA)患者(48名女性;平均年龄63.4岁)和100例行全膝关节置换术(TKA)患者(61名女性;平均年龄66.5岁)中评估活动水平的度量特性。我们通过将这些量表与国际体力活动问卷以及不同的传统患者自我报告结局指标进行关联来评估结构效度。还确定了重测信度、可行性以及地板效应和天花板效应。UCLA量表与其他指标的相关性最强(THA患者中r = -0.35至0.56;TKA患者中r = -0.55至0.23),并且是唯一能够区分行THA和TKA的活动不足与活动充足患者的量表。UCLA量表具有最佳的信度,完成率最高,且无地板效应。它似乎是评估全关节置换术患者身体活动水平最合适的量表。
