The aims of this study were to determine: (1) what factors predict patient self-estimated hand function; (2) what factors predict actual hand function; and (3) the relationship among actual hand function, patient estimates of hand function, and self-assessed activities of daily living (ADL).
Fifty-two patients with rheumatoid arthritis completed wrist and hand mobility measures, grip strength, pain, stiffness, and estimated hand function tests, along with the Sollerman Grip Function Test (actual hand function), Health Assessment Questionnaire (HAQ), and subscales of the Arthritis Impact Measurement Scales (AIMS).
Grip strength and stiffness were the strongest predictors of self-estimated hand function. Flexion and extension deficits in digits II through V were the strongest predictors of actual hand function. Actual hand function and self-estimated hand function were significantly correlated with each other and with the HAQ and AIMS subscales.
Measures of deficit are the most useful in predicting actual hand function, whereas measures of strength and flexibility are most useful for estimated hand function.
本研究的目的是确定：（1）哪些因素可预测患者自我估计的手部功能；（2）哪些因素可预测实际手部功能；以及（3）实际手部功能、患者对手部功能的估计与自我评估的日常生活活动（ADL）之间的关系。
52名类风湿性关节炎患者完成了手腕和手部活动度测量、握力、疼痛、僵硬程度以及估计手部功能测试，同时还进行了索勒曼握力功能测试（实际手部功能）、健康评估问卷（HAQ）以及关节炎影响测量量表（AIMS）的子量表测试。
握力和僵硬程度是自我估计手部功能的最强预测因素。食指至小指的屈伸功能障碍是实际手部功能的最强预测因素。实际手部功能和自我估计的手部功能彼此之间以及与HAQ和AIMS子量表均显著相关。
功能缺损测量对于预测实际手部功能最为有用，而力量和灵活性测量对于估计手部功能最为有用。
