Shoulder Pain and Disability Index (SPADI) calculator

About the score:

Originally published in 1991 in Arthritis and Rheumatology, the Shoulder Pain and Disability Index (SPADI) was designed to provide an instrument that would reflect the disability and pain associated with the clinical syndrome of painful shoulder. It was intended to measure both the current status of shoulder pain as well as changes over time.

The SPADI is a 13-item patient completed instrument. Its categories include “pain” (5 items) and “disability” (8 items), with the total score often described as a percentage, resulting from the summation of each component. Overall total scores range from 0 to 130 with a percentage score of 0 indicating less shoulder disability and 100 indicating more shoulder dysfunction.
