Neuropathic features in subacromial shoulder pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This single-center observational project will enroll 82 adults seen in the Physical Medicine and Rehabilitation outpatient clinic at Izmir City Hospital who have had shoulder pain for at least three months. After informed consent, participants complete validated questionnaires including the Visual Analog Scale (VAS) for pain, painDETECT for neuropathic descriptors, the Central Sensitization Inventory (CSI), and the Shoulder Pain and Disability Index (SPADI), and range of motion is measured with a goniometer. No imaging or invasive procedures are performed; investigators will use painDETECT and CSI results to examine the presence or absence of seven neuropathic pain descriptors and their relationship to central sensitization in subacromial pain syndrome. The goal is to characterize neuropathic and sensitization patterns in this patient group to inform clinical care.
