About

The aim of this study was to investigate predictors of nociplastic shoulder pain. Factors of psychological distress, functionality, fitness, quality of life, quality of sleep, functioning of the parasympathetic system, and lifestyle will be examined. Patients with nociplastic pain will be identified using the classification system proposed by the IASP.

Full description

The main part of the study will include patients with chronic shoulder pain who visit the Hand Surgery-Upper Limb and Microsurgery Department of the General Hospital KAT. The measurements will be performed in one session. Once participants have been informed of the purpose and procedure of the study and given written consent, they will complete their demographics and a series of questionnaires and questions about their pain history. They will then be examined by a doctor and finally subjected to dynamometry, a functional test and two quantitative sensory tests.
