Systematic Review of Shoulder Imaging Abnormalities in Asymptomatic Adult Shoulders (SCRUTINY): Abnormalities of the glenohumeral joint

OBJECTIVE

The primary objective was to determine the population prevalence of glenohumeral joint imaging abnormalities in asymptomatic adults.

METHOD

We systematically reviewed studies reporting the prevalence of X-ray, ultrasound (US), computed tomography, and magnetic resonance imaging (MRI) abnormalities in adults without shoulder symptoms (PROSPERO registration number CRD42018090041). This report presents the glenohumeral joint imaging findings. We searched Ovid MEDLINE, Embase, CINAHL and Web of Science from inception to June 2023 and assessed risk of bias using a tool designed for prevalence studies. The primary analysis was planned for the general population. The certainty of evidence was assessed using a modified Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) for prognostic studies.

RESULTS

Thirty-five studies (4 X-ray, 10 US, 20 MRI, 1 X-ray and MRI) reported useable prevalence data. Two studies were population-based (846 shoulders), 15 studies included miscellaneous study populations (1715 shoulders) and 18 included athletes (727 shoulders). All were judged to be at high risk of bias. Clinical diversity precluded pooling. Population prevalence of glenohumeral osteoarthritis ranged from 15% to 75% (2 studies, 846 shoulders, 1 X-ray, 1 X-ray and MRI; low certainty evidence). Prevalence of labral abnormalities, humeral head cysts and long head of biceps tendon abnormalities were 20%, 5%, 30% respectively (1 study, 20 shoulders, X-ray and MRI; very low certainty evidence).

CONCLUSION

The population-based prevalence of glenohumeral joint imaging abnormalities in asymptomatic individuals remains uncertain, but may range between 30% and 75%. Better estimates are needed to inform best evidence-based management of people with shoulder pain.

Models of care for musculoskeletal shoulder pain in spinal cord injury: A scoping review

CONTEXT

Spinal cord injury (SCI) is a neurological condition that significantly impacts a person's lifestyle, health and well-being. Many individuals with SCI experience secondary musculoskeletal shoulder pain. This scoping review examines the current research on the diagnosis and management of shoulder pain in SCI.

OBJECTIVE

The aim of this Scoping Review was (1) to chart peer-reviewed literature regarding the diagnosis and management of shoulder pain as it relates to SCI and (2) identify gaps in this body of literature to inform future research priorities.

METHODS

Six electronic databases were searched from inception until April 2022. In addition, reviewers scanned the reference lists of identified articles. Articles from peer-reviewed sources that reported diagnostic or management procedures for musculoskeletal shoulder conditions within the SCI population were considered and 1679 articles were identified. Title and abstract screening, full text review, and data extraction were undertaken by two independent reviewers.

RESULTS

Eighty seven articles were included, covering diagnosis or management of shoulder pain in SCI.

CONCLUSION

Whilst the most commonly reported diagnostic procedures and management strategies reflect contemporary practice for shoulder pain, the entire body of literature demonstrates inconsistencies in methodologies. In places, the literature continues to perceive value in procedures inconsistent with best practice. These findings encourage researchers to pursue the development of robust models of care for musculoskeletal shoulder pain in SCI using a collaborative and integrated approach, combining best practice for musculoskeletal shoulder pain alongside clinical expertise in the management of SCI.

Level of diagnostic agreement in musculoskeletal shoulder diagnosis between remote and face-to-face consultations: A retrospective service evaluation

Background and Aims

To determine the level of diagnostic agreement between remote and face-to-face consultation in assessing shoulder complaints.

Methods

A retrospective service evaluation with three groups of patient data; those assessed only face-to-face (group 1), remotely then face-to-face (group 2), remotely only (group 3). Patient data were extracted from 6 secondary care shoulder Advanced Physiotherapy Practitioner's (APPs) records, covering six sites. Three-hundred-and-fifty-nine sets of patient data were included in the final evaluation. The main outcome measure was the percentage of agreement between diagnosis at initial and follow-up consultation, when assessed by APPs across the three groups. A Pearson χ 2 test was used to assess the relationship between the method of consultation and the level of diagnostic agreement. Diagnoses were categorized as either the same, similar, or different by an independent APP. Secondary outcome measures investigated whether age or the length of time between appointments had any effect in determining the level of diagnostic concordance.

Results

There was exact agreement of 77.05% and 85.52% for groups 1 and 3, respectively, compared with 34.93% for patient data in group 2. Similar clinical impressions across both initial and follow-up were seen 16.39% of the time in group 1, 7.24% of the time in group 3, and 36.99% in group 2. Lastly, the percentage of times a diagnosis was changed between initial and review appointments occurred in only 6.56% of group 1 contacts, 7.24% of group 3 contacts, but 28.08% of the time in group 2.

Conclusion

There was a large mismatch in the diagnosis of musculoskeletal shoulder complaints, when patients are initially assessed remotely and then followed-up in-person. This has implications for the future provision of shoulder assessment in physiotherapy.

The relationship between kinesiophobia, balance, and upper extremity functions in patients with painful shoulder pathology

BACKGROUND

Poor balance ability may contribute to shoulder pathology in patients with existing shoulder pathologies or vice versa. The relationship between kinesiophobia and chronic shoulder pain intensity has been researched, although the conclusions are conflicting. To our knowledge, no study in the literature explores the association between kinesiophobia and balance in patients with shoulder pain.

OBJECTIVE

To investigate the relationship between kinesiophobia, upper extremity functions, and balance abilities in patients with shoulder pain.

DESIGN

Cross-sectional observational study.

SETTING

Physical medicine and rehabilitation hospital.

INTERVENTIONS

Not applicable.

PARTICIPANTS

A total of 44 patients with shoulder pain were included in the study.

MAIN OUTCOME MEASURES

The pain severity was assessed using a visual analog scale (VAS). The Tampa Scale for Kinesiophobia (TSK), Berg Balance Scale (BBS), and Shoulder Pain and Disability Index (SPADI) were used to assess the patients. Ultrasound was used to diagnose underlying shoulder joint problems. Static and dynamic postural control was evaluated.

RESULTS

The most common pathologies detected by ultrasound were supraspinatus tendinitis/rupture (77.3%), cortical irregularity (68.2%), and bursitis (63.6%). TSK score did not correlate with age, body mass index, symptom duration, or VAS score in rest (all p > .05), but it was associated with scores on the BBS (r = -0.437, p = .003), SPADI-pain (r = 0.474, p = .001), SPADI-disability (r = 0.355, p = .018), SPADI-total (r = 0.405, p = .006), and VAS in activity (r = 0.331, p = .028). According to multiple linear regression analysis, BBS score, SPADI-total score, and anterior-posterior sway length were significant predictors of TSK (r = 0.645, r2  = 0.416).

CONCLUSIONS

According to the findings of this study, the main risk factors for high levels of kinesiophobia are poor balance, severe pain, and disability. In addition to mechanical causes of shoulder pain, diagnosing and intervening on underlying balance issues and psychosocial causes of shoulder pain will improve treatment success.

The ultrasound assessment of osteoarthritis: the current status

Traditionally, osteoarthritis (OA) is diagnosed with the clinical examination supplemented by the conventional radiography (CR). In the research literature, the role of ultrasound (US) imaging in the diagnostics of OA has risen steadily during the last two decades. US imaging is cheap and globally widely available often already in primary healthcare. Here, we reviewed the most essential US literature focusing on OA diagnostics and progression prediction using the various search engines. Starting from the year 2000, our search provided 1 445 journal articles. After reviewing the abstracts, 89 articles were finally included. Most of the reviewed articles focused on the imaging of knee and hand OA, whereas only a minority dealt with the imaging of hip, ankle, midfoot, acromioclavicular, and temporomandibular joints. Overall, during the last 20 years, the use of US imaging for OA assessment has increased in the scientific literature. In knee and hand joints, US imaging has been reported to be a promising tool to evaluate OA changes. Furthermore, the reproducibility of US as well as its association to MRI findings are excellent. Importantly, US seems to even outperform CR in certain aspects, such as detection of osteophytes, joint inflammation, meniscus protrusion, and localized cartilage damage (especially at the medial femoral condyle and sulcus area). Based on the reviewed literature, US can be truly considered as a complementary tool to CR in the clinical setup for OA diagnostics. New technical developments may even enhance the diagnostic value of the US in the future.

Blood Flow Restriction Training in Nonspecific Shoulder Pain: Study Protocol of a Crossover Randomised Controlled Trial

"Nonspecific shoulder pain" encompasses various non-traumatic musculoskeletal shoulder disorders, diverging from diagnostic terminologies that refer to precise tissue-oriented clinical diagnosis. Blood flow restriction (BFR) training, involving partial arterial inflow and complete venous outflow restriction, has exhibited acute hypoalgesic effects primarily in healthy populations by increasing their pain thresholds. This study aims to examine whether a single BFR session with low-load exercises can alleviate pain perception among nonspecific shoulder pain patients. Conducted as a single-blind crossover randomised clinical trial, 48 adults (age range: 18 to 40) presenting with nonspecific shoulder pain will partake in two trial sessions. Random assignment will place participants into BFR or sham BFR groups and ask them to perform one exercise with BFR. Subsequently, participants will complete a shoulder girdle loading regimen comprising six exercises. The second session will involve participants switching treatment groups. Pain pressure thresholds (PPTs), shoulder pain and disability via the shoulder pain and disability index (SPADI), maximal voluntary isometric contraction (MVIC) of shoulder external rotators, pain during active abduction, and peak pain during shoulder external rotation will be evaluated using the numeric pain rating scale (NPRS). Immediate post-exercise assessments will include patient-perceived pain changes using the global rating of change scale (GROC) and participant-rated perceived exertion (RPE), employing a modified Borg's scale (Borg CR10) post-BFR or sham BFR exercise session. Each session will encompass three assessment periods, and a combination of mixed-effect models and descriptive statistics will underpin the analysis. This protocol was approved by Cyprus National Bioethics Committee (ΕΕΒΚ/2023/48), and was registered in ClinicalTrials.gov (Registration number: NCT05956288). Conclusion: The anticipated outcomes of this study illuminated the acute effects of BFR training on pain perception within the context of nonspecific shoulder pain, potentially advancing strategies for managing pain intensity using BFR techniques.

Kinematic, electromyographic and isokinetic measurements for the management of shoulder subacromial pain syndrome: A systematic review

BACKGROUND

Subacromial shoulder pain syndrome is a very common and challenging musculoskeletal disorder. Kinematics, electromyographic muscle activity and isokinetic dynamometry are promising non-invasive movement analysis tools to improve understanding of this condition. No review has combined their results to provide a better understanding of the effects of subacromial pain syndrome on shoulder movement. This systematic review aimed to synthesise the associations between exposure to shoulder pain due to subacromial pain syndromes or subacromial impingement and changes in shoulder movement measures.

METHODS

The databases were Scholar google, Pubmed, Science Direct, Scopus and the Cochrane Library. We included studies that observed the association of the presence of subacromial pain syndromes or subacromial impingement with changes in shoulder motion measures.

FINDINGS

Seventeen studies with 943 participants were included. The main kinematic change was a lower scapular posterior during abduction in the subacromial pain syndrome group with a "low" level of evidence (standardised mean difference = -0.61, 95% confidence interval [-0.80; -0.43]). The main electromyographic change was an earlier onset of activation of the upper trapezius in the subacromial pain syndrome group, with a "moderate" level of evidence (standardised mean difference = 1.01, 95% confidence interval: [-2.97; 0.96]). The main isokinetic change was a lower peak internal rotator torque in the subacromial pain syndrome group, with a 'low' level of evidence (standardised mean difference = -0.41, 95% confidence interval: [-0.53; -0.29]).

INTERPRETATION

The variables measured during movement are associated with subacromial pain syndrome or subacromial impingement syndrome. Consistency between the results supports the importance of scapula biomechanics measurements in these conditions.

How do people perceive different advice for rotator cuff disease? A content analysis of qualitative data collected in a randomised experiment

OBJECTIVES

To explore how people perceive different advice for rotator cuff disease in terms of words/feelings evoked by the advice and treatment needs.

SETTING

We performed a content analysis of qualitative data collected in a randomised experiment.

PARTICIPANTS

2028 people with shoulder pain read a vignette describing someone with rotator cuff disease and were randomised to: bursitis label plus guideline-based advice, bursitis label plus treatment recommendation, rotator cuff tear label plus guideline-based advice and rotator cuff tear label plus treatment recommendation. Guideline-based advice included encouragement to stay active and positive prognostic information. Treatment recommendation emphasised that treatment is needed for recovery.

PRIMARY AND SECONDARY OUTCOMES

Participants answered questions about: (1) words/feelings evoked by the advice; (2) treatments they feel are needed. Two researchers developed coding frameworks to analyse responses.

RESULTS

1981 (97% of 2039 randomised) responses for each question were analysed. Guideline-based advice (vs treatment recommendation) more often elicited words/feelings of reassurance, having a minor issue, trust in expertise and feeling dismissed, and treatment needs of rest, activity modification, medication, wait and see, exercise and normal movements. Treatment recommendation (vs guideline-based advice) more often elicited words/feelings of needing treatment/investigation, psychological distress and having a serious issue, and treatment needs of injections, surgery, investigations, and to see a doctor.

CONCLUSIONS

Words/feelings evoked by advice for rotator cuff disease and perceived treatment needs may explain why guideline-based advice reduces perceived need for unnecessary care compared to a treatment recommendation.

Progress of Muscle Chain Theory in Shoulder Pain Rehabilitation: Potential Ideas for Pulmonary Rehabilitation

Pulmonary dysfunction is very common in stroke patients. A study has shown that acute stroke patients often cause a series of pulmonary dysfunction due to primary damage to the respiratory center, which is an important reason for hindering disease treatment and recovery. American Thoracic Society (ATS) and the European Respiratory Society (ERS) pointed out that pulmonary rehabilitation (PR) can be applied to the rehabilitation of stroke patients to improve their lung function. PR can improve the respiratory muscle strength of stroke patients, which is beneficial to improving the respiratory function of patients. At the same time, it can also significantly increase the maximum oxygen intake of patients, effectively improve the cardiopulmonary function of stroke patients, and reduce respiratory complications such as aspiration pneumonia. However, the common dysfunction of joints and muscles such as shoulder pain after stroke will affect the process of pulmonary rehabilitation. This is mainly because the changes in the position of the shoulder girdle, the decrease in the range of motion of the cervical and thoracic spine, and the changes in the cervical spondylolisthesis position caused by the elevation of the upper limbs will directly affect the breathing movement during the pulmonary rehabilitation process. The instability of the spine will weaken the deep abdominal muscles and reduce the function of the diaphragm; moreover, changes in the alignment and stability of the cervical and thoracic spine will also lead to wrong breathing methods. Therefore, it is of practical clinical significance to evaluate the functional rehabilitation of shoulder joint muscles and evaluate the efficacy of stroke patients to improve their respiratory function. This article through an extensive review of domestic and foreign literature in recent years, combined with clinical practice experience, summarizes the practical application of chain structure theory in the fields of rehabilitation training, postural adjustment, pain relief, etc., and further studies the functional exercise method based on muscle chain theory. The research on the muscle chain of shoulder pain rehabilitation as a model illustrates the positive effect of reconstructing neuroarticular muscle function on the respiratory system, hoping to provide new ideas for the treatment of respiratory diseases in stroke patients.

The second part of the Guidelines and Recommendations for Musculoskeletal Ultrasound (MSUS), produced under the auspices of EFSUMB, following the same methodology as for Part 1, provides information and recommendations on the use of this imaging modality for joint pathology, pediatric applications, and musculoskeletal ultrasound-guided procedures. Clinical application, practical points, limitations, and artifacts are described and discussed for every joint or procedure. The document is intended to guide clinical users in their daily practice.

Shoulder pain and ultrasound findings: A comparison study of wheelchair athletes, nonathletic wheelchair users, and nonwheelchair users

BACKGROUND

Shoulder pain is one of the most common musculoskeletal concerns in manual wheelchair users including among athletes. However, there is a paucity of research characterizing both shoulder pain and shoulder pathology in this population.

OBJECTIVE

To characterize and compare the prevalence of current shoulder pain and ultrasound metrics of shoulder pathology between wheelchair athletes, nonathletic wheelchair users, and nonwheelchair users.

DESIGN

Cross-sectional.

SETTING

Chicago-area adaptive sport teams/programs and musculoskeletal clinics.

PARTICIPANTS

Thirty-four wheelchair athletes, six nonathletic wheelchair users, and 12 nonwheelchair users.

METHODS

Self-reported shoulder pain was assessed by questionnaire and Wheelchair User Shoulder Pain Index (WUSPI). Shoulder physiology and pathology were assessed by physical and ultrasound evaluation of both shoulders by a sports medicine physician.

MAIN OUTCOME MEASURES

Questionnaire outcomes: Prevalence of current shoulder pain, total WUSPI score. Physical examination outcomes: total Physical Examination of Shoulder Scale (PESS) score. Sonographic outcomes: Acromiohumeral distance (AHD) and presence of shoulder pathology.

RESULTS

The majority of wheelchair athletes (68%) and nonathletic wheelchair users (67%) experienced shoulder pain since using a manual wheelchair. Wheelchair basketball players had a mean WUPSI score of 17.2 (SD = 21.8), and athletes participating in handcycling, sled hockey, and quad rugby had mean scores of 4.91 (SD = 8.32), 7.76 (SD = 13.1), and 4.29 (SD = 7.75), respectively. Shoulder pathology was observed in 14 of 31 (45%) wheelchair athletes and 4 of 6 (67%) nonathletic wheelchair users (p = .41).

CONCLUSIONS

Although wheelchair use is a risk factor for shoulder pain, participation in amateur wheelchair sports may not be associated with increased risk of shoulder pain. It is possible that overhead sports such as wheelchair basketball may define a unique high-risk group. Further study is needed to examine this relationship and to determine whether there are differences between specific wheelchair sports.

Mastering Prognostic Tools: An Opportunity to Enhance Personalized Care and to Optimize Clinical Outcomes in Physical Therapy

In health care, clinical decision making is typically based on diagnostic findings. Rehabilitation clinicians commonly rely on pathoanatomical diagnoses to guide treatment and define prognosis. Targeting prognostic factors is a promising way for rehabilitation clinicians to enhance treatment decision-making processes, personalize rehabilitation approaches, and ultimately improve patient outcomes. This can be achieved by using prognostic tools that provide accurate estimates of the probability of future outcomes for a patient in clinical practice. Most literature reviews of prognostic tools in rehabilitation have focused on prescriptive clinical prediction rules. These studies highlight notable methodological issues and conclude that these tools are neither valid nor useful for clinical practice. This has raised the need to open the scope of research to understand what makes a quality prognostic tool that can be used in clinical practice. Methodological guidance in prognosis research has emerged in the last decade, encompassing exploratory studies on the development of prognosis and prognostic models. Methodological rigor is essential to develop prognostic tools, because only prognostic models developed and validated through a rigorous methodological process should guide clinical decision making. This Perspective argues that rehabilitation clinicians need to master the identification and use of prognostic tools to enhance their capacity to provide personalized rehabilitation. It is time for prognosis research to look for prognostic models that were developed and validated following a comprehensive process before being simplified into suitable tools for clinical practice. New models, or rigorous validation of current models, are needed. The approach discussed in this Perspective offers a promising way to overcome the limitations of most models and provide clinicians with quality tools for personalized rehabilitation approaches.

IMPACT

Prognostic research can be applied to clinical rehabilitation; this Perspective proposes solutions to develop high-quality prognostic models to optimize patient outcomes.

International physical therapists consensus on clinical descriptors for diagnosing rotator cuff related shoulder pain: A Delphi study

BACKGROUND

There is a lack of standardized criteria for diagnosing rotator cuff related shoulder pain (RCRSP).

OBJECTIVE

To identify the most relevant clinical descriptors for diagnosing RCRSP.

METHODS

A Delphi study was conducted through use of an international physical therapists expert panel. A 3-round Delphi survey involving an international panel of physical therapists experts with extensive clinical, teaching, and research experience was conducted. A search query was performed in Web of Science, along with a manual search, to find the experts. The first round was composed of items obtained from a previous pilot Delphi study along with new items proposed by the experts. Participants were asked to rate items across six clinical domains using a five-point Likert scale. An Aiken's Validity Index ≥ 0.7 was considered indicative of group consensus.

RESULTS

Fifteen experts participated in the Delphi survey. After the three rounds, consensus was reached on 18 clinical descriptors: 10 items were included in the "subjective examination" domain, 1 item was included in the "patient-reported outcome measures" domain, 3 items in the "diagnostic examination" domain, 2 items in the "physical examination" domain", and 2 items in the "functional tests" domain. No items reached consensus within the "special tests" domain. The reproduction of symptoms in relation to the application of load, the performance of overhead activities, and the need of active and resisted movement assessment were some of the results with greatest consensus.

CONCLUSION

In this Delphi study, a total of 18 clinical descriptors across six clinical domains were agreed upon for diagnosing RCRSP.

How do people perceive different labels for rotator cuff disease? A content analysis of data collected in a randomised controlled experiment

OBJECTIVES

Explore 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.

SETTING

We performed a content analysis of qualitative data collected in a six-arm, online randomised controlled experiment.

PARTICIPANTS

1308 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 OUTCOMES

Participants 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%).

CONCLUSIONS

Words 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.

Ultrasound Features Associated With Shoulder Complaints: Calcifications Larger Than 6 mm in Young Patients and Positive Doppler Are Associated With Pain

Objectives: To identify ultrasound (US) features associated with the presence of shoulder complaints.

Methods: This observational, case-control study, compared US findings between participants with and without shoulder complaints, matched for age, sex, and dominancy. Data was collected from February 2018 to June 2020. Two-tailed Fisher's and Mann-Whitney U-tests were used, with p-values < 0.05 considered significant.

Results: A total of 202 participants were enrolled (median age 56 years, range 18–70, 155 women), comprising 140 cases and 62 controls. A calcification size ≥6 mm, when age < 56 (p = 0.02), and a distance to tendon insertion ≥6 mm, when age ≥56 (p = 0.009), were only found in symptomatic shoulders. Color Doppler in rotator cuff (RC) tendons predominated in the presence of symptoms (26/140 vs. 2/62, p = 0.003). An algorithm also combining the number of calcifications, tendon echotexture and insertional thickening, osseous irregularity, cuff tears, and subacromial effusion showed a 92% (57/62) specificity for shoulder pain on this study sample.

Conclusion: Calcification diameter of 6 mm or more is associated with shoulder pain in patients younger than 56 years. A distance from calcification to tendon insertion of 6 mm or more is related to pain in older patients. Doppler signal also is associated with shoulder pain. An algorithm based on a set of specific ultrasonographic criteria have a strong association with the presence of symptoms.

Heritability of musculoskeletal pain and pain sensitivity phenotypes: two generations of the Raine Study

ABSTRACT

There is a need to better understand biological factors that increase the risk of persistent musculoskeletal pain and heightened pain sensitivity. Knowing the heritability (how genes account for differences in people's traits) can enhance the understanding of genetic versus environmental influences of pain and pain sensitivity. However, there are gaps in current knowledge, including the need for intergenerational studies to broaden our understanding of the genetic basis of pain. Data from Gen1 and Gen2 of the Raine Study were used to investigate the heritability of musculoskeletal pain, and pressure and cold pain sensitivity. Participants included parents (Gen 1, n=1092) and their offspring (Gen 2, n=688) who underwent a battery of testing and questionnaires including pressure and cold pain threshold testing and assessments of physical activity, sleep, musculoskeletal pain, mental health and adiposity. Heritability estimates were derived using the Sequential Oliogenic Linkage Analysis Routines (SOLAR) software. Heritability estimates for musculoskeletal pain and pressure pain sensitivity were significant, accounting for between 0.190 and 0.289 of the variation in the phenotype. In contrast, heritability of cold pain sensitivity was not significant. This is the largest intergenerational study to date to comprehensively investigate the heritability of both musculoskeletal pain and pain sensitivity, using robust statistical analysis. This study provides support for the heritability of musculoskeletal pain and pain sensitivity to pressure, suggesting the need for further convergence of genetic and environmental factors in models for the development and/or maintenance of these pain disorders.

Consumer understanding of terms used in imaging reports requested for low back pain: a cross-sectional survey

OBJECTIVES

To investigate (1) self-reported societal comprehension of common and usually non-serious terms found in lumbar spine imaging reports and (2) its relationship to perceived seriousness, likely persistence of low back pain (LBP), fear of movement, back beliefs and history and intensity of LBP.

DESIGN

Cross-sectional online survey of the general public.

SETTING

Five English-speaking countries: UK, USA, Canada, New Zealand and Australia.

PARTICIPANTS

Adults (age >18 years) with or without a history of LBP recruited in April 2019 with quotas for country, age and gender.

PRIMARY AND SECONDARY OUTCOME MEASURES

Self-reported understanding of 14 terms (annular fissure, disc bulge, disc degeneration, disc extrusion, disc height loss, disc protrusion, disc signal loss, facet joint degeneration, high intensity zone, mild canal stenosis, Modic changes, nerve root contact, spondylolisthesis and spondylosis) commonly found in lumbar spine imaging reports. For each term, we also elicited worry about its seriousness, and whether its presence would indicate pain persistence and prompt fear of movement.

RESULTS

From 774 responses, we included 677 (87.5%) with complete and valid responses. 577 (85%) participants had a current or past history of LBP of whom 251 (44%) had received lumbar spine imaging. Self-reported understanding of all terms was poor. At best, 235 (35%) reported understanding the term 'disc degeneration', while only 71 (10.5%) reported understanding the term 'Modic changes'. For all terms, a moderate to large proportion of participants (range 59%-71%), considered they indicated a serious back problem, that pain might persist (range 52%-71%) and they would be fearful of movement (range 42%-57%).

CONCLUSION

Common and usually non-serious terms in lumbar spine imaging reports are poorly understood by the general population and may contribute to the burden of LBP.

Bilateral ultrasound findings in patients with unilateral subacromial pain syndrome

Background: Subacromial pain syndrome is a common musculoskeletal shoulder problem. The accuracy of clinical tests is low and techniques such as ultrasound and magnetic resonance imaging have been added to set up a diagnosis. Previous researchers have usually only examined the symptomatic shoulder. However, there might be similar findings in the asymptomatic shoulder. Objective:The aim of the present study was to investigate the prevalence of structural abnormalities of both shoulders in patients with clinically diagnosed unilateral subacromial pain syndrome using diagnostic ultrasound. Methods: Bilateral ultrasound examinations were performed in 115 consecutive patients, 54 men and 61 women. The patients were recruited from primary care centers in the area of Stockholm, Sweden. Results: Abnormal ultrasound findings were found in both shoulders and increased with age (p = .0004). Bursitis was the most common ultrasound finding and significantly more prevalent in the symptomatic shoulder compared to the asymptomatic shoulder (90%:74%; p = .0021), though 73% of the bursitis were bilateral. Supraspinatus is the most vulnerable tendon of the rotator cuff in both shoulders. In terms of partial-thickness tears and tendinosis, the tendon was affected more commonly in the symptomatic shoulder compared to the asymptomatic shoulder (30%:14%: 14%; p = .0026) and (24%:10%; p = .0054), respectively, but for calcification no significant difference between the shoulders was found (18%:12%; 0.1988). Conclusion: Ultrasound detected shoulder abnormalities were present in both symptomatic and asymptomatic shoulders. Bursitis and partial-thickness tears were more common in the affected shoulder when compared to the unaffected shoulder. Ultrasound as well as clinical examination findings and patient´s history should be taken into consideration when diagnosing patients with subacromial pain syndrome.

Shoulder Pain — Where Are We Now?

Purpose of Review

Shoulder pain is common and costly. For the past century, diagnosis and management has been based upon presumed patho-anatomical abnormalities. With the evolution of imaging techniques and new insight about the causes of musculoskeletal pain, this review evaluates the evidence that a patho-anatomical approach remains justified.

Recent Findings

Imaging modalities have developed considerably but, so far, have only proven value in evaluating full thickness rotator cuff tears prior to surgery. Correlation between imaging findings and symptoms is otherwise poor, with limited evidence of the value and impact of imaging for decision-making. Much of shoulder pain is chronic and few people have single-site musculoskeletal pain. Pain studies suggest that chronic shoulder pain is associated with both central and peripheral pain sensitisation. Moreover, functional MRI points to an effect of cognitive affective pain processing rather than nociception. Few of the established therapies, medical or surgical, that treat the presumed patho-anatomical cause have been shown to have lasting benefit.

Summary

Much of the evidence suggests that shoulder pain is more similar than different from mechanical low back pain. For most people with shoulder pain, the best approach might well be de-medicalisation, support to (self)manage pain, emphasis on retaining movement and identifying adverse beliefs and risk factors for disability and chronicity. Approaches like this are currently being evaluated and more research is desperately required.

Diagnostic Labels for Rotator Cuff Disease Can Increase People's Perceived Need for Shoulder Surgery: An Online Randomized Controlled Trial

OBJECTIVE

To investigate whether different labels for rotator cuff disease influence people's perceived need for surgery.

DESIGN

Randomized controlled experiment.

METHODS

Participants with and without shoulder pain read a vignette describing a patient with rotator cuff disease and were randomized to 1 of 6 terms describing rotator cuff disease: subacromial impingement syndrome, rotator cuff tear, bursitis, rotator cuff-related shoulder pain, shoulder sprain, and episode of shoulder pain. Perceived need for shoulder surgery was the primary outcome. Secondary outcomes included perceived need for imaging, an injection, a second opinion, and to see a specialist; perceived seriousness of the condition; recovery expectations; and perceived impact on work attendance. Using a Bonferroni correction (significance, P<.003), adjusted between-group mean differences and 99.67% confidence intervals (CIs) were obtained using a 1-way analysis of covariance.

RESULTS

One thousand three hundred eight (80% of 1626) responses were analyzed. Participants' mean ± SD age was 40.3 ± 16.0 years, and 59% were women. Mean perceived need for surgery (0-10 scale) was low and slightly higher among those assigned to the rotator cuff tear label compared to the bursitis label (2.6 versus 2.1; adjusted mean difference, 0.7; 99.67% CI: 0.0, 1.4). Mean perceived need for imaging (0-10) was moderate and slightly higher among those assigned to the rotator cuff tear (4.7 versus 3.7; adjusted mean difference, 1.0; 99.67% CI: 0.2, 1.9) and subacromial impingement syndrome labels (4.7 versus 3.7; adjusted mean difference, 1.0; 99.7% CI: 0.1, 1.9) compared to the bursitis label.

CONCLUSION

There were small differences in the perceived need for surgery and imaging between some labels, which could be important at the population level. J Orthop Sports Phys Ther 2021;51(8):401-411. Epub 31 Mar 2021. doi:10.2519/jospt.2021.10375.

Ultrasound of shoulder and knee improves the accuracy of the 2012 EULAR/ACR provisional classification criteria for polymyalgia rheumatica

Objective

Recent studies suggest that the knee is frequently involved in PMR. In this study, we aimed to determine whether the US assessment of the shoulder and knee discriminates between PMR and other differential diagnoses and improves the accuracy of the 2012 EULAR/ACR provisional classification criteria for PMR.

Methods

We consecutively enrolled 81 untreated patients who received a diagnosis of PMR. These patients were divided into two groups based on the final diagnosis made at 1-year follow-up: PMR-definite group (n = 60) and PMR-mimic group (n = 21). We also enrolled age/sex-matched untreated RA patients with shoulder pain from an independent cohort (RA group, n = 60). All patients underwent comprehensive US assessment of the shoulder and knee for synovitis, bursitis, tenosynovitis, tendinitis and ligament inflammation at baseline.

Results

US scores for tenosynovitis, tendinitis and ligament inflammation better discriminated the PMR-definite group from the PMR-mimic and RA groups than do those for synovitis or bursitis. Among logistic regression models to identify US variables that were associated with the PMR-definite group, the best fitted model included two US variables: the bilateral involvement of the shoulder (long head of biceps, supraspinatus or subscapularis tendon) and the bilateral involvement of the knee (popliteus tendon or medial or lateral collateral ligament). Incorporating these two items into the 2012 EULAR/ACR provisional classification criteria numerically increased the accuracy to classify the PMR-definite group.

Conclusion

US assessment of the tendon/ligament-related lesions in the shoulder and knee may improve the accuracy of the 2012 EULAR/ACR provisional classification criteria for PMR.

High-Intensity Shoulder Abduction Exercise in Subacromial Pain Syndrome

Subacromial pain syndrome (SAPS) defined as pain of nontraumatic origin localized around the acromion, is a debilitating, common, and often chronic condition. Among many proposed underlying causes of SAPS, hypoperfusion and hypoxic conditions in and around the tendons may be an intrinsic cause of SAPS.

PURPOSE

This study aimed to determine if adding high-intensity aerobic interval training (HIIT) of the rotator cuff to usual care was feasible in SAPS and improved shoulder endurance more than usual care alone, as well as to examine the influence on shoulder pain and disability and the response of tendinous microcirculation after HIIT.

METHODS

Twenty-one subjects with chronic SAPS were randomized to two groups: experimental group (EG; n = 13) receiving HIIT in addition to treatment as usual and control group (CG; n = 8) receiving treatment as usual. Before and after 8 wk of exercise therapy, endurance performance was assessed by an incremental abduction exercise of the arm to exhaustion (TTE). Pain and disability was assessed by the shoulder pain and disability index (SPADI). Contrast-enhanced ultrasound of the musculus supraspinatus and tendon was utilized to indicate tendon blood flow.

RESULTS

Endurance in the TTE test improved by an estimated 233 s more on average in EG than in CG (P = 0.001; 95% confidence interval, 102 to 363). The SPADI score was reduced 22 points more on average in EG (P = 0.017; 95% confidence interval, -40 to -5). The change from pretest to posttest was significant in EG for both TTE test and SPADI improvement (P < 0.001). EG also experienced less pain during exercise after the intervention compared with CG (P < 0.001). Contrast-enhanced ultrasound indicated an increase in tendinous blood flow in EG (P = 0.019).

CONCLUSIONS

HIIT rotator cuff exercise seems to be a feasible intervention in SAPS, increasing endurance performance more than usual care alone.

Ultrasonographic Evaluation of the Shoulders and Its Associations with Shoulder Pain, Age, and Swim Training in Masters Swimmers

Background and objectives: The long head of the biceps (LHB) and rotator cuff tendinopathy is the major cause of shoulder pain in competitive swimmers. The risk of tendinopathy increases with aging; however, the structural changes of LHB and rotator cuff in populations of masters swimmers have not been well examined. The purpose of this study was to investigate the prevalence of ultrasonographic abnormalities of the shoulders in masters swimmers, and the association of pain, age, and swim training with structural changes in this population. Materials and Methods: A total of 60 subjects participated in this study, with 20 masters swimmers with shoulder pain, 20 asymptomatic masters swimmers, and 20 sex- and age-matched controls. All swimmers completed a self-reported questionnaire for shoulder pain, their history of competition, and training volume. Each subject underwent ultrasonographic examination of both shoulders for pathologic findings in the LHB tendon, rotator cuff (supraspinatus (SSP) and subscapularis (SSC)) tendons, and subacromial bursa (SAB) of both shoulders and had thickness measured. Results: The prevalence of tendinosis (LHB, 48.8%; SSP, 17.5%; SSC, 15.9%), partial tear (SSP, 35.0%), and calcification (SSC, 10.0%) were higher in swimmers than in controls. LHB and SSP tendinosis were associated with shoulder pain. Older age and later start of competition were associated with an increased risk of LHB tendinosis and SSC calcification. Earlier initiation of swimming and longer history of competition were associated with an increased risk of SSP and SSC tendinosis. The thicker SSP tendon significantly increased the risk of tendinosis and partial tear. Conclusions: A high prevalence of structural changes in the rotator cuff and biceps tendons in masters swimmers reflects the effect of shoulder symptoms, aging, and swim training.

What Is the Diagnosis in Patients with Type 2 Diabetes Who Have a Painful Shoulder? Results from a Prospective Cross-Sectional Study

Background: Patients with diabetes mellitus have higher risk of developing shoulder pathology. However, only adhesive capsulitis is addressed in shoulder pain guidelines as a disorder associated with diabetes. Yet, patients with diabetes are at risk of having several other shoulder disorders, including focal neuropathy. Our aim was to quantify the presence of shoulder disorders using physical examination and ultrasound imaging in patients with type 2 diabetes (T2DM) suffering from shoulder pain in general practice. Methods: In this prospective cross-sectional study, patients with T2DM who had had a painful shoulder for at least four weeks were included. Patients filled out a questionnaire and underwent a physical examination of the shoulders and feet and ultrasound imaging of the shoulder. Results: A total of 66 patients were included, of whom 40.9% (n = 27) had bilateral complaints resulting in 93 symptomatic shoulders. Subacromial pain syndrome was most frequently diagnosed by physical examination (66.6%, 95% CI 51.6–72.0%; p < 0.0001), while ultrasound imaging showed that subacromial disorders were statistically significantly the most prevalent (90.3%, 95% CI 81.9–95.2%). Only two patients (3%) were diagnosed with neuropathic shoulder pain. Conclusion: When choosing treatment, general practitioners should be aware that in patients with T2DM the subacromial region is most frequently affected.

Guidelines for the use of diagnostic imaging in musculoskeletal pain conditions affecting the lower back, knee and shoulder: A scoping review

BACKGROUND

Musculoskeletal (MSK) pain is one of the most common reasons for primary care consultation, particularly pain in the lower back (LBP), knee and shoulder. The use of diagnostic imaging for MSK pain is increasing, but it is unclear whether this increase is justified on the basis of clinical practice guideline (CPG) recommendations.

AIM

To identify and map the content of CPGs that informs the use of diagnostic imaging in those with nontraumatic LBP, knee and shoulder pain in primary and intermediate care in the UK.

DESIGN AND SETTING

A scoping review of CPGs.

METHODS

This scoping review was conducted and is reported in accordance with PRISMA guidance. A broad search strategy included electronic searches of MEDLINE, CINAHL, PsychINFO and SPORTDiscus from 2009 to 17 April 2019. This was conducted alongside a search of guideline repositories and was combined with a snowball search of Google, relevant professional bodies and use of social media.

RESULTS

31 relevant CPGs were included. Routine use of diagnostic imaging for those with nontraumatic LBP, knee or shoulder pain is generally discouraged in primary care or intermediate care. Diagnostic imaging should be reserved for when specific or serious pathology is suspected or where the person is not responding to initial nonsurgical management and the imaging result is expected to change clinical management decisions.

CONCLUSION

Diagnostic imaging should not be routinely requested in primary or intermediate care for nontraumatic LBP, knee or shoulder pain. CPGs do not justify the increasing imaging rates in the UK for MSK pain.

Benefits of distal clavicle resection during rotator cuff repair: Prospective randomized single-blind study

INTRODUCTION

Rotator cuff tears often occur in combination with acromioclavicular (AC) arthropathy. But it can be difficult to separate pain caused by the rotator cuff tear from pain caused by the AC joint, despite clinical and other examinations. Distal clavicle resection (DCR) is increasingly being done at the same time as arthroscopic rotator cuff repair. The aim of this study was to compare the functional outcomes 1 year after arthroscopic rotator cuff repair between patients who simultaneously undergo DCR and patients who do not. The primary hypothesis was that DCR improves the clinical outcomes.

MATERIAL AND METHODS

This was a prospective, multicenter, randomized, single-blind study of 200 patients who underwent isolated supraspinatus repair using the same technique. The patients were randomized into two groups: 97 patients who also underwent DCR and 103 patients who did not. The patients were followed until 1 year postoperative according to a standardized radiological and clinical review protocol.

RESULTS

At 1 year postoperative, all the clinical outcomes were worse in the DCR group, although only external rotation with elbow at side (53° vs. 59°, p=0.04) and the SSV (86.5 vs. 90.1, p=0.04) were statistically different. Overall shoulder pain was higher in the DCR group during the first 3 months postoperative (p=0.04). At 1 year, the DCR group had more residual pain; this pain was mainly located on the superior side of the shoulder (p=0.03), especially when more than 11 mm was resected (p=0.01). More of the shoulders in the DCR group had failures in rotator cuff healing based on ultrasonography (p=0.5).

CONCLUSION

Our hypothesis was not confirmed. We do not recommend doing routine DCR with arthroscopic rotator cuff repair.

Prevalence of asymptomatic radiological findings in the groin region: a systematic review

Objective: The aim of this study is to investigate in current literature the prevalence of asymptomatic adductor and pubic abnormalities on MRI and ultrasound. Methods: A systematic review of the literature was carried out using PubMed to identify all studies reporting asymptomatic pubic- and adductor-related findings on MRI and/or ultrasound. All types of studies were eligible for inclusion, except case reports. Studies with an asymptomatic cohort, or where at least a part of the study population was asymptomatic, were included. Results: Thirteen studies were included. Two articles describe only asymptomatic adductor abnormalities, six articles only asymptomatic pubic abnormalities. Five articles describe both adductor and pubic abnormalities. All studies were conducted with MRI. Only one of the included articles describes asymptomatic groin findings on ultrasound. Conclusions: Asymptomatic adductor and pubic abnormalities on MRI are frequently present but vary greatly between selected studies. No exact conclusions can be drawn about the prevalence of asymptomatic adductor or pubic findings on MRI due to high heterogeneity between studies. Furthermore, the one article about ultrasound was not enough to draw conclusions for ultrasound findings. It is nonetheless clear that clinicians should be careful to make diagnoses purely based on radiologic findings. A thorough clinical examination and individual interpretation conducted by the clinician remains indispensable.

Subacromial Impingment Syndrome does not alter muscle onset activation patterns during shoulder cardinal movement at different speed and load

This study examines neuromuscular firing patterns in healthy and subjects diagnosed with SIS of the periscapular, prime-moving, and rotator cuff muscles during "clinical" cardinal plane physiological movements at different speeds and loads. EMG recordings were taken in 34 healthy and 34 subjects diagnosed with Subacromial Impingement Syndrome (SIS) of the prime movers, periscapular, and rotator cuff muscles during flexion, scaption, and abduction performed at fast, medium, and slow speeds with a loaded (3 kg) and unloaded arm. Differences in firing patterns between groups were analyzed by fitting mixed linear models with random intercepts per subject, and fixed factors for group, muscle, movement type, speed, and load. No difference in timing of activation was seen between the healthy and SIS. Onset timing of prime movers, periscapular, and rotator cuff muscles were prior to movement in all scenarios studied, with rotator cuff muscles firing last. Speed and load appear to independently vary muscle activation timing in a non-intuitive manner in both healthy and SIS. The lack of different firing neuromuscular patterns in subjects diagnosed with SIS and healthy subjects raises the need to consider individual assessment of motor patterns rather than generalized patterns.

The relationship of the acromion to the distal clavicle in normal and symptomatic degenerated acromioclavicular joints

INTRODUCTION

Although degenerative osteoarthritis of the acromioclavicular joint is a common finding on technical investigations, not every patient experiences pain or function loss. The difference between symptomatic and asymptomatic patients is currently not elucidated. Therefore, we want to investigate the acromioclavicular relationship in normal, asymptomatic, and symptomatic degenerated ACJ.

MATERIALS AND METHODS

84 normal ACJ, 39 asymptomatic degenerated ACJ, and 30 symptomatic degenerated ACJ were 3D reconstructed. The morphological dimensions and the relationship of the acromion and distal clavicle were measured using computational software. The reproducibility of this technique was evaluated using inter- and intra-observer reliability.

RESULTS

The mean anteroposterior and superoinferior distance of both the clavicle and acromion was significantly larger in asymptomatic and symptomatic degenerative ACJ compared to the normal ACJ (p < 0.001). In symptomatic osteoarthritic ACJ, both the anterior and posterior borders of the acromion were significantly more anterior to the borders of the clavicle than in the normal group and asymptomatic group (p < 0.001). Subsequent ROC curve analysis resulted in a sensitivity of 86.7% and a specificity of 88.6% for anterior subluxation of the ACJ. This technique showed an excellent inter- and intra-observer reliability.

CONCLUSIONS

In patients with degenerative ACJ, both the distal clavicle and acromion are enlarged. In asymptomatic patients, the AC relationship is the same as in normal patients, in contrast, in patients with symptomatic degenerative ACJ, the acromion is subluxated anteriorly compared to the clavicle.

Symptomatic Achilles Tendons are Thicker than Asymptomatic Tendons on Ultrasound Examination in Recreational Long-Distance Runners

There is a need for clinical indicators that can be used to guide the treatment of Achilles tendon complaints in recreational runners. Diagnostic ultrasound has recently been introduced for clinical decision support in tendon pain management. The aim of this study was to determine whether tendon thickness and morphological changes in the Achilles tendon detected in ultrasound examinations are associated with local symptoms in middle-age recreational long-distance runners. Forty-two Achilles tendons (21 middle-aged runners) were investigated by ultrasound examination measuring tendon thickness and a morphology score indicating tendinosis. The Generalized Estimating Equations method was applied in multiple models of factors associated with reporting a symptomatic tendon. Eleven symptomatic and 31 asymptomatic Achilles tendons were recorded. In the multiple model that used tendon thickness measured 30 mm proximal to the distal insertion, an association was found between thickness and reporting a symptomatic tendon (p < 0.001; OR 12.9; 95% CI 3.1 to 53.2). A qualitative morphology score was not found to be significantly associated with reporting a symptomatic tendon (p = 0.10). We conclude that symptomatic Achilles tendons were thicker than asymptomatic tendons on ultrasound examination among recreational long-distance runners and that the importance of parallel morphological findings need to be further investigated in prospective studies.

Bilateral magnetic resonance imaging findings in individuals with unilateral shoulder pain

BACKGROUND

Magnetic resonance imaging (MRI) is commonly used to diagnose structural abnormalities in the shoulder. However, subsequent findings may not be the source of symptoms. The aim of this study was to determine comparative MRI findings across both shoulders of individuals with unilateral shoulder symptoms.

MATERIALS AND METHODS

We prospectively evaluated 123 individuals from the community who had self-reported unilateral shoulder pain with no signs of adhesive capsulitis, no substantial range-of-motion deficit, no history of upper-limb fractures, no repeated shoulder dislocations, and no neck-related pain. Images in the coronal, sagittal, and axial planes with T1, T2, and proton density sequences were generated and independently and randomly interpreted by 2 examiners: a board-certified, fellowship-trained orthopedic shoulder surgeon and a musculoskeletal radiologist. Absolute and relative frequencies for each MRI finding were calculated and compared between symptomatic and asymptomatic shoulders. Agreement between the shoulder surgeon and the radiologist was also determined.

RESULTS

Abnormal MRI findings were highly prevalent in both shoulders. Only the frequencies of full-thickness tears in the supraspinatus tendon and glenohumeral osteoarthritis were higher (approximately 10%) in the symptomatic shoulder according to the surgeon's findings. Agreement between the musculoskeletal radiologist and shoulder surgeon ranged from slight to moderate (0.00-0.51).

CONCLUSION

Most abnormal MRI findings were not different in frequency between symptomatic and asymptomatic shoulders. Clinicians should be aware of the common anatomic findings on MRI when considering diagnostic and treatment planning.

Asymptomatic Rotator Cuff Tears

Asymptomatic rotator cuff tears (RCTs) are prevalent in the general population; they are positively associated with age and are common in the contralateral shoulder of individuals who are being treated for shoulder pain or a symptomatic RCT. Asymptomatic RCTs are likely to become symptomatic over time, corresponding with decreased patient-reported function, strength, and range of motion. Previous studies have largely reported inconsistent findings regarding patient-reported outcomes, strength, range of motion, and kinematics in individuals with asymptomatic RCTs. Future research would benefit from characterizing any functional alteration that is associated with asymptomatic rotator cuff pathology, including determining whether such alterations are detrimental or compensatory and understanding the mechanism by which an asymptomatic RCT becomes symptomatic.

Does the outcome of diagnostic ultrasound influence the treatment modalities and recovery in patients with shoulder pain in physiotherapy practice? Results from a prospective cohort study

STUDY DESIGN

Prospective cohort study including patients with shoulder pain in primary care physiotherapy.

BACKGROUND

There is an increased tendency to use diagnostic ultrasound to aid the diagnostic strategy and target treatment. It is a relatively cheap and accessible imaging technique but the implications for practice and patients are unknown.

OBJECTIVES

To study the influence of diagnostic ultrasound (DUS) on diagnostic work-up, treatment modalities and recovery.

METHODS

Participants (n = 389) with a new episode of shoulder pain were assessed at baseline and followed for 6, 12 and 26 weeks. Diagnostic work-up, including the use of DUS, and treatment strategies were reported by the therapists at 3, 6 and 12 weeks.

RESULTS

Most patients (41%) were diagnosed with subacromial impingement/pain syndrome after physical examination or DUS. DUS was used in 31% of the participants. Tendinopathy was the most found abnormality in this sub-population. Patients who underwent DUS were more frequently treated using exercise therapy. Patients that not had DUS were more likely to receive massage therapy, trigger point therapy or mobilisation techniques. Logistic regression analyses did not show a significant association between DUS and recovery after 26 weeks (0.88, 95%CI:0.50-1.57). Correcting for the therapist as a confounder using a multilevel binary logistic regression did not show a significant cluster effect.

CONCLUSION

Diagnostic US as a work-up component does not seem to influence diagnosis or recovery but does influence the choice of treatment modality. Conclusions are limited to observational data. High quality randomized trials should study the effect of DUS on recovery.

Rotator Cuff-Related Shoulder Pain: To Inject or Not to Inject?

The most common source of shoulder pain is thought to involve the tendons of the rotator cuff and associated structures around the subacromial space. A generic diagnostic term has been suggested, rotator cuff-related shoulder pain (RCRSP), which is an overarching clinical term that includes a number of conditions, such as subacromial impingement syndrome, subacromial pain syndrome, and rotator cuff tendinopathy. The management of RCRSP may include exercise, surgery, or injection therapy. Those who perform or recommend injection therapy for RCRSP have a duty of care to provide advice on the expected benefits and outcomes, as well as the potential risks and associated harms. Clinicians also need to consider what medication to inject, where to inject it, and how to inject it. The aim of this Viewpoint is to discuss these issues.

What does best practice care for musculoskeletal pain look like? Eleven consistent recommendations from high-quality clinical practice guidelines: systematic review

OBJECTIVES

To identify common recommendations for high-quality care for the most common musculoskeletal (MSK) pain sites encountered by clinicians in emergency and primary care (spinal (lumbar, thoracic and cervical), hip/knee (including osteoarthritis [OA] and shoulder) from contemporary, high-quality clinical practice guidelines (CPGs).

DESIGN

Systematic review, critical appraisal and narrative synthesis of MSK pain CPG recommendations.

ELIGIBILITY CRITERIA

Included MSK pain CPGs were written in English, rated as high quality, published from 2011, focused on adults and described development processes. Excluded CPGs were for: traumatic MSK pain, single modalities (eg, surgery), traditional healing/medicine, specific disease processes (eg, inflammatory arthropathies) or those that required payment.

DATA SOURCES

Four scientific databases (MEDLINE, Embase, CINAHL and Physiotherapy Evidence Database) and four guideline repositories.

RESULTS

6232 records were identified, 44 CPGs were appraised and 11 were rated as high quality (low back pain: 4, OA: 4, neck: 2 and shoulder: 1). We identified 11 recommendations for MSK pain care: ensure care is patient centred, screen for red flag conditions, assess psychosocial factors, use imaging selectively, undertake a physical examination, monitor patient progress, provide education/information, address physical activity/exercise, use manual therapy only as an adjunct to other treatments, offer high-quality non-surgical care prior to surgery and try to keep patients at work.

CONCLUSION

These 11 recommendations guide healthcare consumers, clinicians, researchers and policy makers to manage MSK pain. This should improve the quality of care of MSK pain.

Higher order thinking about differential diagnosis

BACKGROUND

Differential diagnosis is a systematic process used to identify the proper diagnosis from a set of possible competing diagnoses.

METHODS

The goal of this masterclass is to discuss the higher order thinking components of differential diagnosis.

CONCLUSIONS

For healthcare providers, diagnosis is one of many necessary components during the clinical decision making process and it is hallmarked by differentiation of competing structures for a definitive understanding of the underlying condition. The diagnostic process involves identifying or determining the etiology of a disease or condition through evaluation of patient history, physical examination, and review of laboratory data or diagnostic imaging; and the subsequent descriptive title of that finding. Whereas differential diagnosis is a varied skill set among all healthcare providers, the concept of a diagnosis is equally germane, regardless of one's background. In theory, a diagnosis improves the use of classification tools, improves clarity and communication, provides a trajectory of treatment, improves understanding of a person's prognosis, and in some cases, may be useful for preventative treatments. To achieve these improvements, one must have an understanding of relation of the clinical utility of tests and measures with diagnosis, and how to best implement these findings in clinical practice. This requires a deeper understanding (higher order thinking) of the role of diagnosis in the management of patients.

Perspectives of participants with rotator cuff-related pain to a neuroscience-informed pain education session: an exploratory mixed method study

Purpose: To explore perceptions and initial outcomes of patients with rotator cuff-related pain to a pain education session.Materials and Methods: Ten individuals with persistent rotator cuff-related pain (≥3 months duration) attended an individual pain education session. They completed patient-reported outcomes measures on a weekly basis, three weeks prior and three weeks following the session. Individual semi-structured interviews were conducted three weeks following the pain education. Interviews were recorded, transcribed verbatim, and analyzed using the General Inductive Approach.Results: There were two over-arching key themes: firstly, 'Participants' Perspectives' of the session generated four themes: Improved understanding of 'the whole'; Mindful self-awareness; Taking charge; "The pain is still there". Their understanding of pain was reconceptualised, evident by their ability to describe the role of neurophysiological mechanisms, stress and general well-being towards their pain. The second over-arching key theme, 'Participants' Recommendations', had two themes: Integrating neuroscience with pathoanatomical knowledge and Educating other health professionals. Pain levels decreased post-pain education compared to pre-pain education.Conclusions: Following the pain education session, participants had greater understanding of factors influencing their shoulder pain. Pain education, in addition to pathoanatomical information may be useful as part of treatment for persistent rotator cuff-related pain.

Preliminary reliability and validity of the shoulder functional reach score

OBJECTIVE

The purpose of this study was to determine (a) if the newly developed shoulder functional reach score (SFRS) is reliable; (b) if the SFRS demonstrates construct validity by being able to differentiate between patients' symptomatic and asymptomatic shoulders; (c) if the SFRS is able to detect changes over time; and (d) if the potential changes in the SFRS demonstrated criterion validity at three different time intervals by being associated the Numeric Pain Rating Scale (NPRS) and Shoulder Pain and Disability Index (SPADI).

METHODS

Patients were consecutively screened for consultation related to complaints of shoulder pain. Thirty-eight subjects agreed to participate and signed informed consent. Twenty-nine subjects fulfilled the study after the 4 weeks of follow-up. Outcome measures were collected at the initial evaluation and at the first follow-up visit prior to the initiation of treatment. Data were then collected after 2 and 4 weeks of treatment.

RESULTS

There were statistically significant differences between symptomatic and asymptomatic shoulders on the SFRS. Intratester reliability of the SFRS was intraclass correlation coefficient (ICC_2,1 ) = 0.94. Intertester reliability of the SFRS was ICC_2,1  = 0.92. Statistically significant differences were observed between the initial evaluation, 2 and 4 weeks for the SFRS, SPADI, and NPRS. Moderate (r_s  = 0.62) to strong (r_s  = 0.87) positive correlations were observed between the NPRS and SPADI. Moderate negative (r_s  = -0.50-0.51) correlations were found between the SFRS and the SPADI. Moderate negative (r_s  = -0.36-0.54) statistically significant (p < 0.05) correlations were found between the SFRS and the NPRS.

CONCLUSION

In this small sample, the SFRS was an objective, reliable, and valid tool for assessing shoulder active range of motion in a clinical setting.

Multimodality imaging of subacromial impingement syndrome

Subacromial impingement syndrome results from irritation of the tendons of the rotator cuff muscles in the subacromial space and may manifest as a range of pathologies. However, subacromial impingement is a dynamic condition for which imaging reveals predisposing factors but no pathognomonic indicators. Also, the usual imaging features of subacromial impingement may be seen in symptomatic and asymptomatic patients. Therefore, imaging is able to detect tears and describe the risk factors of impingement but cannot confirm subacromial impingement. Radiographs allow assessment of the morphology of the acromion and its lateral extension by means of the acromial index and the critical shoulder angle, which may increase in cases of subacromial impingement. Ultrasound is necessary to evaluate a tendon tear and is the only tool that provides dynamic information, which is essential to assessing dynamic conditions. Magnetic resonance imaging (MRI) allows the assessment of associated intraarticular abnormalities, joint effusion, and bone marrow edema. The objective of this article is to provide an overview of the pathophysiology and clinical manifestations of subacromial impingement and discuss recent advances in the imaging of subacromial impingement and the role of radiography, ultrasound, and MRI in differentiating normal from pathologic findings.

Towards an integrated clinical framework for patient with shoulder pain

Background

Shoulder pain (SP) represents a common musculoskeletal condition that requires physical therapy care. Along the years, the usual evaluation strategies based on clinical tests and diagnostic imaging has been challenged. Clinical tests appear unable to clearly identify the structures that generated pain and interpretation of diagnostic imaging is still controversial. The current patho-anatomical diagnostic categories have demonstrated poor reliability and seem inadequate for the SP treatment.

Objectives

The present paper aims to (1) describe the different proposals of clinical approach to SP currently available in the literature; to (2) integrate these proposals in a single framework in order to help the management of SP.

Conclusion

The proposed clinical framework, based on a bio-psychosocial vision of health, integrates symptoms characteristics, pain mechanisms and expectations, preferences and psychosocial factors of patients that may guide physiotherapist to make a diagnostic triage and to choose the right treatment for the individual patient.

Ultrasound-guided subacromial-subdeltoid bursa corticosteroid injections: a study of short- and long-term outcomes

AIM

To assess shoulder pain and disability in patients undergoing corticosteroid injection into the subacromial-subdeltoid (SA-SD) bursa under ultrasound guidance, evaluating both short and long-term outcomes.

MATERIALS AND METHODS

In this prospective, longitudinal, analytical study 376 patients referred for SA-SD bursa injection during a 6 month period were asked to complete a questionnaire assessing shoulder pain and disability in the form of the Shoulder Pain and Disability Index (SPADI). Patients were reassessed at 6 weeks and 12 months post-injection. Data were collated and analysed based on the diagnosis made at ultrasound.

RESULTS

Almost two-thirds (63.6%) of patients irrespective of the underlying diagnosis showed improvement in pain and disability 6 weeks after injection, but this figure decreased significantly after 12 months to 27.3%. There was no significant difference in outcome between patients with a rotator cuff tendon tear and without a tear at 6 weeks; however, there was a difference between these two groups at 12 months with significantly fewer patients with a tear receiving benefit.

CONCLUSION

The pattern of good short-term, but poorer long-term outcomes from SA-SD bursa injection is in line with previous studies; however, this study provides additional information on the effect of the underlying diagnosis on the potential outcome, specifically the presence or absence of a rotator cuff tendon tear.
