Summary

This study looked at 87 people with frozen shoulder to see if their level of central sensitization—a condition where the nervous system is extra sensitive to pain—affected how well they responded to a shoulder injection. Researchers measured central sensitization using a questionnaire and tracked pain levels after the injection. The goal was to better understand why some patients improve more than others.
