The Stanmore Percentage of Normal Shoulder Assessment (SPONSA) is a simple, fast and reproducible measure of the subjective state of a shoulder. It has been invaluable in our busy clinical practice. This study validates the SPONSA score against the Oxford Shoulder and Constant score and demonstrates a greater sensitivity to change. The SPONSA involves defining the concept of ‘normality’ in a shoulder and then asking patients to express the current state of their shoulder as a percentage of normal. The score uses a specific script which is read exactly as typed. The SPONSA, Oxford Shoulder and Constant scores were measured by an independent observer in 61 consecutive patients undergoing treatment for shoulder conditions in our unit. Scores were recorded at 2-6 weeks before admission, immediately before intervention, and between 3-6 months post-intervention. The time taken to measure each score was recorded.Introduction
