Description

The Oxford Shoulder Score (OSS-12) is a patient-reported assessment instrument designed to evaluate the impact of shoulder conditions on an individual’s daily functioning and well-being.

The questionnaire consists of 12 items covering two main areas: shoulder function and pain. Through the patient’s responses, the OSS-12 provides a quantitative indication of how shoulder-related problems affect everyday activities and health-related quality of life.

Objective

The primary objective of the OSS-12 is to provide a quantitative measure of shoulder functional ability and the impact of shoulder-related pain on quality of life.

The instrument can be used to assess treatment effectiveness, monitor patient progress over time, and identify areas where additional clinical intervention may be required.

Structure and Scoring

The OSS-12 contains 12 questions addressing two principal areas:

Function: Assessment of the extent to which the shoulder condition affects the individual’s ability to perform everyday activities.

Pain: Assessment of the impact of shoulder pain on the individual’s overall functioning and daily experience.

According to the provided material, each item is rated on a Likert-type scale ranging from 0 to 4, producing a total score between 0 and 48. Under the scoring system described in the document, lower scores indicate poorer shoulder function and a greater impact of pain.

Data Analysis and Use

The total OSS-12 score can be used to provide a quantitative summary of the patient’s shoulder-related condition and to compare outcomes across different assessment points.

Repeated administration can support the monitoring of clinical progress and the evaluation of changes following therapeutic interventions.

In research settings, descriptive and comparative statistical analyses may also be used to examine differences in OSS-12 scores across groups or assessment periods.

Clinical Applications

The OSS-12 can be used in the assessment of individuals experiencing shoulder problems and in the evaluation of treatment outcomes.

Its relatively brief format facilitates its inclusion in clinical and research protocols, while its patient-reported format provides information directly from the individual’s perspective regarding pain and functional limitations.

The instrument may also be used to evaluate outcomes following shoulder surgery and to monitor changes in function before and after treatment.

Interpretation

Interpretation of OSS-12 results should follow the scoring system used for the specific version of the instrument being administered.

The overall score provides a concise indication of shoulder function and the impact of pain. However, the results should be interpreted in conjunction with the broader clinical assessment rather than used independently.
