To develop a computerized adaptive testing system of the Fugl-Meyer motor scale (CAT-FM) to efficiently and reliably assess motor function in patients with stroke.
First, a simulation study was used to develop and examine the psychometric properties of the CAT-FM. Second, a field study was employed to determine the administration efficiency of the CAT-FM.
One medical center and 1 teaching hospital.
Patients' responses (n=301) were used for the simulation study; 49 patients participated in the field study.
Not applicable.
The 2 CAT-FM item banks (upper extremity and lower extremity) include 37 items from the original Fugl-Meyer scale. The reliability, validity, and responsiveness of the CAT-FM were determined by the simulation study.
Two stopping rules (reliability ≥0.9 or an increase of reliability <.01 after testing an item) were used. The simulation study showed that the CAT-FM had high reliability (≥.93 for upper-extremity and lower-extremity subscales) and concurrent validity (Pearson r≥.91 for the upper-extremity and lower-extremity subscales and motor scale). The responsiveness was moderate (standardized response mean for the upper extremity=.67, lower extremity=.79, and motor=.77) for the 226 patients who completed both assessments at 14 and 90 days after stroke. The field study found that, on average, the time needed to administer the CAT-FM was 242 seconds with 4.7 items.
The CAT-FM is an efficient, reliable, valid, and responsive clinical tool for assessing motor function in patients with stroke.
开发一种 Fugl-Meyer 运动量表（CAT-FM）的计算机自适应测试系统，以有效地、可靠地评估中风患者的运动功能。
首先，进行模拟研究以开发和检验 CAT-FM 的心理测量特性。其次，进行现场研究以确定 CAT-FM 的管理效率。
一个医疗中心和 1 所教学医院。
模拟研究使用了 301 名患者的反应；49 名患者参加了现场研究。
不适用。
2 个 CAT-FM 项目库（上肢和下肢）包括原始 Fugl-Meyer 量表中的 37 个项目。通过模拟研究确定 CAT-FM 的可靠性、有效性和反应性。
使用了 2 种停止规则（可靠性≥0.9 或测试项目后可靠性增加<.01）。模拟研究表明，CAT-FM 具有高可靠性（上肢和下肢子量表≥.93）和同时效度（上肢和下肢子量表以及运动量表的 Pearson r≥.91）。对 226 名在中风后 14 天和 90 天完成两次评估的患者进行的反应性评估为中度（上肢标准化反应均值=.67，下肢=.79，运动=.77）。现场研究发现，平均而言，使用 CAT-FM 进行管理所需的时间为 242 秒，需要 4.7 个项目。
CAT-FM 是一种高效、可靠、有效且敏感的临床工具，可用于评估中风患者的运动功能。
