The UCLA Shoulder Score is one of the oldest shoulder PRO measures in use today, and is a jointly completed score, with both physician and patient completed portions. The original UCLA Scale was published in 1981 and includes the following three domains: pain, function, and muscle power and motion. The questionnaire is a combined objective and subjective survey that requires completion by both the doctor and patient. There has been published a modified UCLA Scale and a patient-reported UCLA Scale.

The number of items varies between three items (original UCLA Scale) and seven items (modified version with the addition of two new items for abduction). The most commonly used version (the modified UCLA Scale) and the patient-reported UCLA Scale both have five items.

All items have weighted scores out of 10, based on categorical responses; all three items are completed by the clinician, and each of the three items is scored out of a maximum of 10 points.

In the modified version, there are six similar response options for pain and function, although the numerical weightings differ; three items are completed by the patient (pain, function, and satisfaction), and two are completed by the clinician or observer (active forward flexion and strength of forward flexion).

In the modified patient-reported version, all items are completed by the patient.

Agreement between the modified UCLA Scale and the patient-reported UCLA Scale was shown. Acceptable agreement in a postoperative population of patients who had undergone either arthroscopic subacromial decompression or rotator cuff repair ( N = 100), with values as follows: ICC = 0.910 (95% CI 0.87-0.94) for the whole cohort, ICC = 0.951 (95% CI 0.92-0.97) for the cohort with subacromial decompression (n = 46), and ICC = 0.734 (95% CI 0.61-0.83) for the cohort with rotator cuff repair (n = 54).
