Central Sensitization and Functional Outcomes in Chronic Shoulder Pain (SHOULDER-CS)

13 de junho de 2026 atualizado por: Ayşenur Yılmaz, Pamukkale University

The Effects of Central Sensitization and Psychological Factors on Functional Outcomes Following Rehabilitation in Individuals With Chronic Shoulder Pain

This prospective observational cohort study aims to investigate whether baseline central sensitization and psychological factors predict functional outcomes following rehabilitation in individuals with chronic shoulder pain. Participants with chronic shoulder pain will receive a standardized 6-week physiotherapy and rehabilitation program routinely applied in the clinic. Assessments will be performed before and after treatment, including pain severity, shoulder function, central sensitization symptoms, and psychological factors such as pain catastrophizing. The findings of this study may contribute to a better understanding of biopsychosocial factors affecting rehabilitation outcomes in chronic shoulder pain and help improve individualized rehabilitation approaches.

Descrição detalhada

Chronic shoulder pain is one of the most common musculoskeletal disorders and is associated with pain, functional limitations, reduced quality of life, and work disability. Although structural abnormalities are often identified in clinical evaluation and imaging findings, the relationship between tissue pathology and symptom severity is not always clear. Therefore, factors beyond peripheral tissue damage may contribute to persistent shoulder pain and rehabilitation outcomes.

In recent years, central sensitization has become an important concept in chronic musculoskeletal pain conditions. Central sensitization refers to increased responsiveness of the central nervous system to sensory input, resulting in pain hypersensitivity and amplification of pain perception. Previous studies have demonstrated that individuals with chronic shoulder pain may present with symptoms related to central sensitization, which can negatively affect pain severity, disability, and treatment response.

Psychological factors such as pain catastrophizing, fear of movement, anxiety, and depression are also known to influence chronic pain experiences and rehabilitation outcomes. Higher levels of maladaptive psychological responses may contribute to increased pain perception, reduced treatment adherence, and poorer functional recovery. However, prospective studies evaluating the combined influence of central sensitization and psychological factors on rehabilitation outcomes in chronic shoulder pain remain limited.

This study is designed as a prospective observational cohort study. Individuals with chronic shoulder pain attending physiotherapy rehabilitation clinics will be recruited. Participants will undergo baseline assessments before treatment and follow-up assessments after a standardized 6-week rehabilitation program routinely applied in clinical practice.

The primary objective is to determine whether baseline central sensitization and psychological factors predict functional improvement following rehabilitation. The findings may contribute to a better understanding of the biopsychosocial mechanisms underlying treatment response and support the development of more individualized rehabilitation strategies for chronic shoulder pain management.

O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Shoulder Pain and Disability Index (SPADI)
Prazo: Baseline and 6 weeks after rehabilitation
The Shoulder Pain and Disability Index (SPADI) is a validated questionnaire used to assess shoulder pain and disability. Total scores range from 0 to 100, with higher scores indicating greater pain and disability.
Baseline and 6 weeks after rehabilitation

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Central Sensitization Inventory (CSI)
Prazo: Baseline and 6 weeks after rehabilitation
The Central Sensitization Inventory is a self-reported questionnaire assessing symptoms related to central sensitization. Scores range from 0 to 100, with higher scores indicating greater central sensitization symptoms.
Baseline and 6 weeks after rehabilitation
Pain Catastrophizing Scale (PCS)
Prazo: Baseline and 6 weeks after rehabilitation
The Pain Catastrophizing Scale (PCS) assesses exaggerated negative thoughts and emotional responses related to pain. Total scores range from 0 to 52, with higher scores indicating greater pain catastrophizing.
Baseline and 6 weeks after rehabilitation
Pain Intensity (Visual Analog Scale)
Prazo: Baseline and 6 weeks after rehabilitation
Pain intensity will be assessed using a Visual Analog Scale (VAS) ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity.
Baseline and 6 weeks after rehabilitation
Shoulder Range of Motion
Prazo: Baseline and 6 weeks after rehabilitation
Shoulder range of motion will be assessed using standard goniometric measurements. Higher values indicate greater shoulder joint mobility.
Baseline and 6 weeks after rehabilitation
Shoulder Muscle Strength
Prazo: Baseline and 6 weeks after rehabilitation
Shoulder muscle strength will be evaluated using standardized clinical strength assessment procedures. Higher values indicate greater muscle strength.
Baseline and 6 weeks after rehabilitation
