简要总结
This single-center observational study aims to investigate neuropathic pain descriptors and their relationship with central sensitization in patients diagnosed with subacromial pain syndrome (SAPS) who have had shoulder pain for at least 3 months. A total of 82 participants aged 19 years or older will be recruited from the Physical Medicine and Rehabilitation outpatient clinic of Izmir City Hospital. After obtaining informed consent, participants will complete validated questionnaires assessing pain severity (VAS), neuropathic pain characteristics (painDETECT), central sensitization (Central Sensitization Inventory), and shoulder function (SPADI). Range of motion will be measured using a goniometer. No imaging or invasive procedures will be performed. Using the central sensitization scale and pain detect, the presence or absence of the 7 pain descriptors will be investigated in patients with subacromial pain syndrome with or without central sensitization and neuropathic pain pattern and it will be investigated whether the contribution of hyperalgesia, one of these pain descriptors, to neuropathic pain and central sensitization in patients with subacromial pain syndrome is greater than the contribution of other pain descriptors.The results of this study are expected to provide insight into pain mechanisms and guide clinical management in patients with SAPS.

结局指标
主要结局
Hyperalgesia
时间窗: At baseline (single assessment)
Hyperalgesia is defined as an exaggerated pain response to a painful stimulus that is disproportionate to the intensity of the stimulus. It is one of the pain descriptors assessed in the painDETECT questionnaire, which evaluates neuropathic pain features.It is one of the 7 questions in the painDETECT scale that evaluates neuropathic pain and is scored on a 6-point Likert scale and receives a score between 0-5.
