Study of Neuropathic Pain Features and Central Sensitization in Adults with Subacromial Shoulder Pain

What this Trial Is About

Researchers are investigating the characteristics of neuropathic pain and its connection to central sensitization in people diagnosed with subacromial pain syndrome SAPS, a condition involving shoulder pain lasting at least three months. This observational study will enroll 82 adults aged 19 years or older from a physical medicine and rehabilitation clinic. The study aims to understand how different pain descriptors, especially hyperalgesia, relate to neuropathic pain and central sensitization in SAPS patients. Participants will complete several validated questionnaires evaluating pain intensity using the Visual Analog Scale VAS, neuropathic pain features with painDETECT, central sensitization with the Central Sensitization Inventory, and shoulder function through the Shoulder Pain and Disability Index SPADI. A physical examination will measure the shoulders range of motion using a goniometer. No imaging or invasive procedures will be performed during the study. Throughout the study, researchers will assess the presence of specific pain descriptors related to neuropathic pain and central sensitization patterns. They will analyze hyperalgesia at a single baseline assessment alongside other measures such as pain intensity, neuropathic pain, central sensitization, shoulder function, and range of motion. This information aims to improve understanding of pain mechanisms and support better clinical management for individuals with SAPS.
