Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants, both male and female, with chronic shoulder pain for at least 3 months will be included in the study. They will complete several questionnaires and a functional test. Spearman's correlation will be used to analyze associations between symptoms of CS and pain behavior, functioning, pain, pain catastrophizing, kinesiophobia, and illness perceptions.

Additionally, a between-group analysis will be performed to compare patients with and without clinically relevant symptoms of CS.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

(1)chronic unilateral shoulder pain (Chronic pain will be defined as pain lasting for 3 or more months. Also, pain intensity will be at least 3 on a 0-10 numerical pain rating scale on most days of the last 3 months).

Exclusion Criteria

1. recent shoulder dislocation (1 year prior) and/or systemic diseases such as rheumatoid arthritis, fibromyalgia and/or polymyalgia rheumatic
2. shoulder pain considered to be originated from the cervical region, and other traumas,
3. neurological dysfunction (ie, multiple sclerosis or stroke), osteoporosis, haemophilia and/or cancer
4. shoulder surgery
5. participants with shoulder pain after post fracture
6. Being pregnant or given birth in the preceding year
7. Overconsumption of alcohol or any other recreational drug2
8. Cognitive impairment
9. inability to provide informed consent and/or complete written questionnaires

If participants use medication with a known influence on the central nervous system (eg, anti-epileptic and antidepressant, analgesics, and/or NSAID's), it should be stable in medication intake for at least 1 month prior to his/her participation to be included in this study (Kuppers et al. 2017). Patients are required to continue usual care at least 6 weeks prior to study participation to obtain a steady state.
