ObjectivesExplore how people perceive different labels for rotator cuff disease in terms of words or feelings evoked by the label and treatments they feel are needed.SettingWe performed a content analysis of qualitative data collected in a six-arm, online randomised controlled experiment.Participants1308 people with and without shoulder pain read a vignette describing a patient with rotator cuff disease and were randomised to one of six labels: subacromial impingement syndrome, rotator cuff tear, bursitis, rotator-cuff-related shoulder pain, shoulder sprain and episode of shoulder pain.Primary and secondary outcomesParticipants answered two questions (free-text response) about: (1) words or feelings evoked by the label; (2) what treatments they feel are needed. Two researchers iteratively developed coding frameworks to analyse responses.Results1308/1626 (80%) complete responses for each question were analysed. Psychological distress (21%), uncertainty (22%), serious condition (15%) and poor prognosis (9%) were most often expressed by those labelled with subacromial impingement syndrome. For those labelled with a rotator cuff tear, psychological distress (13%), serious condition (9%) and poor prognosis (8%) were relatively common, while minor issue was expressed least often compared with the other labels (5%). Treatment/investigation and surgery were common among those labelled with a rotator cuff tear (11% and 19%, respectively) and subacromial impingement syndrome (9% and 10%) compared with bursitis (7% and 5%).ConclusionsWords or feelings evoked by certain labels for rotator cuff disease and perceived treatment needs may explain why some labels drive management preferences towards surgery and imaging more than others.

Relevance. Owing to its controlling action on the inflammatory process, pain-relieving and reparative effects the RPR-therapy became quite demanded for treatment of certain types of tendinopathies specified by prevalence of degenerative process and poor reparative potential. Purpose of the study — to evaluate the efficiency of PRP-therapy in patients with tendinopathies of rotator cuff (RC) long head of biceps (LHB) tendons. Material and Methods. The paper presents the results of two-center prospective study for application of autologous platelet rich plasma in treatment of 122 patients: 53 men and 69 women aging 46.8±6.8 years who suffered RC tendinopathy (66%), subacromial impingement syndrome and RC tendinopathy (17%) and LHB tendinopathy (17%). Treatment outcomes were evaluated in 1, 3 and 6 months after PRP-therapy using various scales — VAS, UCLA , DASH, — and instrumental examination methods (US, MRI). Results. The authors observed statistically significant improvement in pain and functional scores in all three groups as compared to reported scores prior to PRP-therapy during 6 months follow up. During this period of evaluation, the scores of UCLA and DASH in patients with RC tendinopathy improved at 8.6 and 36.4 points, with subacromial impingement syndrome and RC tendinopathy — at 9.6 and 38.8 points, with LHB tendinopathy — at 11.5 and 44.1 point, respectively. The most notable reduction of pain syndrome by VAS was achieved in treatment of LHB tendinopathy (at 5.4 points) and RC tendinopathy (at 5.2 point). The highest average scores of satisfaction with treatment outcomes were reported in patients with RC tendinopathy (2.3) and LHB tendinopathy (2.2). MRI and ultrasound examinations after PRP-therapy demonstrated improved structure of RC and LHB tendons — decreased or eliminated swelling, areas of hypoechoic signal. Conclusion. PRP-therapy in patients with RC and LHB tendons and with subacromial impingement syndrome with RC tendinopathy significantly reduces severity of pain and improved the shoulder joint function with positive dynamics during 6 months follow up.

Subacromial impingement syndrome is a clinical diagnosis encompassing a spectrum of possible etiologies, including subacromial bursitis, rotator cuff tendinopathy, and partial- to full-thickness rotator cuff tears. This report presents an unusual case of subdeltoid lipoma causing extrinsic compression and subacromial impingement syndrome. The patient, a 60-year-old man, presented to our institution with a few years' history of nontraumatic, posteriorly localized throbbing pain in his right shoulder. Despite a well-followed 6-months physiotherapy program, the patient was still suffering from his right shoulder. The MRI scan revealed a well-circumscribed 6 cm × 2 cm × 5 cm homogenous lesion compatible with a subdeltoid intermuscular lipoma. The mass was excised en bloc, and subsequent histopathologic examination confirmed a benign lipoma. At 6-months follow-up, the patient was asymptomatic with a complete return to his activities. Based on this case and a review of the literature, a subacromial lipoma has to be included in the differential diagnosis of a subacromial impingement syndrome refractory to nonoperative treatment. Complementary imaging modalities are required only after a failed conservative management to assess the exact etiology and successfully direct the surgical treatment.

Rotator Cuff Tendinopathy

Subacromial impingement syndrome (SAIS) represents a spectrum of pathology ranging from subacromial bursitis to rotator cuff tendinopathy and full-thickness rotator cuff tears. The relationship between subacromial impingement and rotator cuff disease in the etiology of rotator cuff injury is a matter of debate. However the etiology is multi-factorial, and has been attributed to both extrinsic and intrinsic mechanisms. Management includes physical therapy, injections, and, for some patients, surgery. No high-quality RCTs are available so far to provide possible evidence for differences in outcome of different treatment strategies. There remains a need for high-quality clinical research on the diagnosis and treatment of SAIS.

Clinicians suggest that rehabilitation of Subacromial Impingement Syndrome (SIS) should target improving movement patterns to ensure better clinical outcomes. Understanding changes in onset time of activation patterns and associated changes in clinical outcomes could improve our understanding of rehabilitation strategies. In this prospective longitudinal study, we examined neuromuscular firing patterns and clinical features before and after a standardized physiotherapy program in subjects diagnosed with SIS. Electromyography (EMG) recordings of eleven shoulder muscles were taken at the initial and discharge consultation in 34 male volunteers diagnosed with SIS. EMG recording was performed during flexion, scaption, and abduction at slow, medium, and fast speeds with a loaded (3 kg) and unloaded arm, as well as rotational motion, rotational strength, pain, and shoulder function. Completion of standardized shoulder physiotherapy program for SIS resulted in improvements in clinical outcomes. Resulted showed inconsistent differences of onset time of activation mainly in some of the periscapular muscles for all movements. No differences were seen on the EMG recordings for rotator cuff muscles. Differences in range of motion, strength and function were shown. Despite some changes in onset time of activation, this study was not able to demonstrate consistent changes of onset time of activation of the periscapular and rotator cuff muscles.
