Grip strength has traditionally been seen as an objective measurement of hand function, while the Patient-Reported Outcomes Measurement Information System Upper Extremity (PROMIS UE) has emerged recently as a common patient-reported outcome metric for similar purposes. The primary objective of this study was to determine if a correlation exists between grip strength, PROMIS UE, and Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) scores in hand and upper extremity clinic patients. PROMIS UE, Pain Interference (PI), and Depression (D), as well as QuickDASH were prospectively administered to patients from July 16 to September 3, 2020. A grip strength ratio (GSR), calculated by dividing the grip strength of the injured hand by that of the noninjured hand, was recorded for each individual to control for personal differences in grip strength. Data were analyzed using Spearman's correlation coefficients with the significance level at < 0.05. Fifty patients participated in this study. The median GSR was 0.55. QuickDASH demonstrated strong correlations with both PROMIS UE and PI ( (48) = -0.81, < 0.05; (48) = 0.86, < 0.05). GSR correlated moderately with PROMIS UE ( (48) = 0.63, < 0.05). Finally, GSR and QuickDASH also exhibited moderate correlation with each other ( (48) = -0.62, < 0.05). PROMIS UE and QuickDASH are shown to correlate moderately with GSR. This suggests the PROMIS UE forms as an effective measure of hand/wrist function in hand clinic patients and may be substituted for grip strength measurements.
传统上，握力一直被视为手部功能的客观测量指标，而患者报告结局测量信息系统上肢版（PROMIS UE）最近已成为用于类似目的的常见患者报告结局指标。本研究的主要目的是确定手部和上肢门诊患者的握力、PROMIS UE以及手臂、肩膀和手部快速残疾评估量表（QuickDASH）评分之间是否存在相关性。2020年7月16日至9月3日，对患者前瞻性地进行了PROMIS UE、疼痛干扰（PI）、抑郁（D）以及QuickDASH评估。记录每个人的握力比值（GSR），即受伤手的握力除以未受伤手的握力，以控制握力的个体差异。使用Spearman相关系数分析数据，显著性水平设定为<0.05。五十名患者参与了本研究。GSR中位数为0.55。QuickDASH与PROMIS UE和PI均显示出强相关性（r(48)= -0.81，P<0.05；r(48)= 0.86，P<0.05）。GSR与PROMIS UE呈中度相关（r(48)= 0.63，P<0.05）。最后，GSR和QuickDASH之间也表现出中度相关性（r(48)= -0.62，P<0.05）。结果表明，PROMIS UE与GSR呈中度相关。这表明PROMIS UE可作为手部门诊患者手/腕部功能的有效测量指标，可能替代握力测量。
