SHOULDER

ASES Shoulder Score

The ASES contains physician-rated and patient-rated sections, with only the Pain visual analog score (VAS) and ten functional questions used to calculate the reported ASES score.
The final pain score (maximum 50 points) is calculated by subtracting the VAS score from 10 and multiplying by 5. For the functional score, each of 10 separate questions is scored on an ordinal scale from 0-3 for a maximal raw functional score of 30 points. The raw score is multiplied by 5/3 to make the maximal functional score out of 50 possible points. The pain and functional portions are then summed to obtain the final ASES score (maximum of 100).
The minimal clinically important difference [MCID] for the ASES Score is estimated to be 27.1 points for arthroscopic rotator cuff repair and 21 points for shoulder arthroplasty

SPADI (The Shoulder Pain And Disability Index)

The SPADI measures two dimensions of shoulder disability - Pain and Functional activities. The score consists of 13 items (5 for Pain dimension and 8 for Functional activity).
Each item is scored on a 10cm visual analogue scale. These are added up to calculate the Pain and Function subscales as percentages of the maximum possible score (50 for Pain and 80 for Function). The Total SPADI is calculated as a percentage of the maximum possible score of 130. Higher scores represent higher disability.
