Outcome measures for lateral elbow tendinopathy are most informative when they capture how the condition affects pain and daily function from the patient’s perspective, while also allowing some standardized comparison across patients. The PRTEE is a disease-specific instrument designed for lateral elbow tendinopathy, measuring both pain and function related to elbow tasks. The DASH provides a broad assessment of upper-extremity disability, which is useful for capturing overall impact on arm, shoulder, and hand function. The PSFS adds patient-specific insight by letting individuals rate the difficulty of tasks that matter most to them, making the measure highly sensitive to change in everyday activities. Using this combination gives a well-rounded view: a focused elbow-specific symptom tool, a general upper-extremity function index, and a personalized functional assessment. In contrast, shoulder-focused scores or purely objective measures like ROM, pressure pain thresholds, or grip strength don’t consistently reflect the patient’s perceived impact on daily life in lateral elbow tendinopathy, and thus are less commonly used as a standard trio for this condition.
