“…Eleven studies investigated rotator cuff tears [ 33 – 36 , 39 , 54 – 59 ]. Decreased supraspinatus vascularity or blood flow was observed in two studies [ 55 , 58 ], and reduced supraspinatus functional capillary density in another [ 54 ].…”

“…Decreased supraspinatus vascularity or blood flow was observed in two studies [ 55 , 58 ], and reduced supraspinatus functional capillary density in another [ 54 ]. In patients with unilateral rotator cuff tears with night pain, increased peak systolic velocity and decreased resistance index in the anterior humeral circumflex artery was observed in the symptomatic side in comparison to the asymptomatic side [ 59 ].…”

“…Reduced trapezius blood flow and relative blood volume [ 73 , 74 , 80 , 81 ] and oxygen saturation at rest and in response to upper extremity tasks [ 75 , 77 , 81 ] occurred with trapezius myalgia and neck/shoulder pain. Lastly, reduced blood flow and altered vascular parameters were observed in rotator cuff tears [ 54 , 55 , 58 , 59 ].…”

Background: This study systematically summarizes quantitative imaging biomarker research in non-traumatic neck and shoulder musculoskeletal disorders (MSDs). There were two research questions: 1) Are there quantitative imaging biomarkers associated with the presence of neck and shoulder MSDs?, 2) Are there quantitative imaging biomarkers associated with the severity of neck and shoulder MSDs? Methods: PubMed and SCOPUS were used for the literature search. One hundred and twenty-five studies met primary inclusion criteria. Data were extracted from 49 sufficient quality studies. Results: Most of the 125 studies were cross-sectional and utilized convenience samples of patients as both cases and controls. Only half controlled for potential confounders via exclusion or in the analysis. Approximately one-third reported response rates. In sufficient quality articles, 82% demonstrated at least one statistically significant association between the MSD(s) and biomarker(s) studied. The literature synthesis suggested that neck muscle size may be decreased in neck pain, and trapezius myalgia and neck/shoulder pain may be associated with reduced vascularity in the trapezius and reduced trapezius oxygen saturation at rest and in response to upper extremity tasks. Reduced vascularity in the supraspinatus tendon may also be a feature in rotator cuff tears. Five of eight studies showed an association between a quantitative imaging marker and MSD severity. Conclusions: Although research on quantitative imaging biomarkers is still in a nascent stage, some MSD biomarkers were identified. There are limitations in the articles examined, including possible selection bias and inattention to potentially confounding factors. Recommendations for future studies are provided.

“…[ 30 ] As all of our patients were referrals for an ultrasound examination due to various shoulder symptoms, it could be concluded that small tears were not prevalent in our population. As night-time pain is indicative of a chronic inflammatory process with an increase in blood flow, [ 31 ] we speculated that large-sized tears caused persistent inflammation and thus more pain at night in our group.…”
