Abstract
Introduction: Rotator cuff related shoulder pain (RCRSP) is one of the most common health problems associated with dysfunction and persistent pain. Emerging evidence suggests that pain sensitization plays an important role in dysfunction and persistent pain in RCRSP.
Objective: To conduct a systematic review on the prevalence of pain sensitization in RCRSP, and to determine its association with patient-reported outcomes.
Method: MEDLINE/PubMed, EMBASE, CINAHL, Web of Science were systematically searched for studies from inception to June 2023. Studies that describing the prevalence and correlation with clinical outcomes in RCRSP using self-reported questionnaires and quantitative sensory testing (QST) were included. Two reviewers independently assessed the quality of studies using the Newcastle-Ottawa Scale (NOS).
Results: A total of 8 studies were included. There were four studies of high quality and four studies of moderate quality (NOS= 6 – 8). The rate of pain sensitization in RCRSP ranged between 7.2% and 39.4%. Individuals with RCRSP demonstrated lower pressure pain threshold (PPT) in muscles around the symptomatic shoulder when compared to healthy individuals, including supraspinatus, infraspinatus, deltoid, biceps brachii and subscapular muscles (p<0.008), indicating the presence of peripheral sensitization. However, no conclusive evidence regarding changes in PPT in distal muscles (i.e., tibialis anterior muscle) was found. Besides, there is moderate correlation between PPT and pain intensity, but inconclusive evidence is found for correlation between PPT and duration of symptoms and shoulder function.
Conclusions: The rate of pain sensitization in RCRSP ranged between 7.2% and 39.4%. There is a moderate correlation between pain sensitization and pain intensity, while the correlation between pain sensitization and duration of symptoms or shoulder function is inconclusive. Pain sensitization is a problem to be prioritized during assessments and further research needs to be done to determine the potential of present treatment options.
