Hypothesis
The study investigates the reproducibility and responsiveness of the Shoulder Pain and Disability Index (SPADI) in patients with adhesive capsulitis.
Conclusion
The study supports the use of SPADI as an effective outcome measure for patients with adhesive capsulitis.
Supporting Evidence
- SPADI showed a smallest detectable difference of 17 points.
- The intraclass correlation coefficient for SPADI was 0.89.
- SPADI was more responsive than shoulder range-of-motion measures.
- 60% of the variance in SPADI improvement was explained by baseline SPADI and active ROM changes.
Takeaway
The SPADI questionnaire is a good tool to see how much better or worse someone's shoulder pain and ability to do things has gotten over time.
Methodology
The study used test-retest reliability and responsiveness assessments with a sample of 76 patients undergoing treatment for adhesive capsulitis.
Potential Biases
Potential session bias may have affected the results due to the timing of measurements.
Limitations
Some patients were not able to participate in the SPADI reproducibility substudy for practical reasons.
Participant Demographics
Patients included were outpatients with adhesive capsulitis attending a rehabilitation department.
