What is the UEFI?
The Upper Extremity Functional Index (UEFI) is a self-administered questionnaire designed to measure the functional limitations experienced by individuals with upper extremity musculoskeletal dysfunction. It is a patient-reported outcome measure (PROM), meaning that it relies on the patient’s own perception of their functional abilities. This makes it a valuable tool for capturing the subjective experience of living with an upper limb condition.
The UEFI consists of 20 items, each of which assesses the difficulty a patient experiences in performing a specific activity of daily living (ADL). These activities encompass a wide range of tasks, including personal hygiene, dressing, household chores, work activities, and leisure pursuits. Each item is rated on a 5-point Likert scale, ranging from “no difficulty” to “unable to do.” The total score for the UEFI ranges from 0 to 80, with higher scores indicating greater functional impairment.
The UEFI’s focus on functional limitations in everyday activities is crucial for understanding the impact of upper limb conditions on a patient’s quality of life. It goes beyond simply measuring pain or range of motion, providing a more comprehensive assessment of the patient’s ability to participate in the activities that are important to them. This information is essential for clinicians in developing personalized treatment plans and for researchers in evaluating the effectiveness of interventions.
Purpose and Applications of the UEFI
The UEFI serves several important purposes in the clinical management and research of upper extremity conditions.

Reliability and Validity of the UEFI
The UEFI has been subjected to rigorous testing to ensure its reliability and validity as a measure of upper extremity function. Several studies have investigated the UEFI’s internal consistency, test-retest reliability, and construct validity. Internal consistency refers to the degree to which the items within a questionnaire measure the same underlying construct. Studies have demonstrated high internal consistency for the UEFI, indicating that its items are measuring a single, coherent concept of upper extremity function.
Test-retest reliability assesses the consistency of the questionnaire over time. Studies have shown that the UEFI exhibits good test-retest reliability, suggesting that scores obtained at different time points are consistent, provided that the patient’s condition remains stable. Construct validity refers to the extent to which a questionnaire measures the theoretical construct it is designed to assess. Research has supported the UEFI’s construct validity, demonstrating that it correlates well with other established measures of upper extremity function, such as the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire.
The UEFI’s demonstrated reliability and validity make it a valuable tool for clinicians and researchers. Its ability to provide consistent and accurate measurements of upper extremity function allows for reliable monitoring of patient progress, evaluation of treatment effectiveness, and comparison of outcomes across different studies.
Clinical Applications of the UEFI
The UEFI plays a crucial role in various clinical settings, providing valuable insights into the functional status of patients with upper extremity conditions. Clinicians utilize the UEFI to assess the impact of these conditions on patients’ daily lives, allowing them to tailor treatment plans effectively. For instance, the UEFI can help determine the extent to which a patient’s upper extremity dysfunction interferes with activities of daily living, such as dressing, eating, or writing.
The UEFI also serves as a valuable tool for monitoring patient progress during rehabilitation. By administering the UEFI at different stages of treatment, clinicians can track improvements in upper extremity function and adjust treatment strategies as needed. This allows for personalized care and ensures that patients receive the most effective interventions. Furthermore, the UEFI can be employed to evaluate the effectiveness of different treatment modalities, such as physical therapy, occupational therapy, or surgery.
