Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at people with shoulder pain lasting at least 3 months to understand if nerve-related pain and a condition called central sensitization (where the nervous system becomes overly sensitive) play a role. Researchers will use questionnaires and simple movement tests—no needles or scans. The goal is to help doctors better treat shoulder pain by identifying these hidden pain patterns.
