Clinician Facial Expression of Emotion Corresponds with Patient Mindset.

Mental health has a notable and perhaps underappreciated relationship with symptom intensity related to musculoskeletal pathophysiology. Tools for increasing awareness of mental health opportunities may help musculoskeletal specialists identify and address psychological distress and unhealthy misconceptions with greater confidence. One such type of technology-software that identifies emotions by analyzing facial expressions-could be developed as a clinician-awareness tool. A first step in this endeavor is to conduct a pilot study to assess the ability to measure patient mental health through specialist facial expressions. (1) Does quantification of clinician emotion using facial recognition software correlate with patient psychological distress and unhealthy misconceptions? (2) Is there a correlation between clinician facial expressions of emotions and a validated measure of the quality of the patient-clinician relationship? In a cross-sectional pilot study, between April 2019 and July 2019, we made video recordings of the clinician's face during 34 initial musculoskeletal specialist outpatient evaluations. There were 16 men and 18 women, all fluent and literate in English, with a mean age of 43 ± 15 years. Enrollment was performed according to available personnel, equipment, and room availability. We did not track declines, but there were only a few. Video recordings were analyzed using facial-emotional recognition software, measuring the proportion of time spent by clinicians expressing measured emotions during a consultation. After the visit, patients completed a demographic questionnaire and measures of health anxiety (the Short Health Anxiety Inventory), fear of painful movement (the Tampa Scale for Kinesiophobia), catastrophic or worst-case thinking about pain (the Pain Catastrophizing Scale), symptoms of depression (the Patient Health Questionnaire), and the patient's perception of the quality of their relationship with the clinician (Patient-Doctor Relationship Questionnaire). Clinician facial expressions consistent with happiness were associated with less patient health anxiety (r = -0.59; p < 0.001) and less catastrophic thinking (r = -0.37; p = 0.03). Lower levels of clinician expressions consistent with sadness were associated with less health anxiety (r = 0.36; p = 0.04), fewer symptoms of generalized anxiety (r = 0.36; p = 0.03), and less catastrophic thinking (r = 0.33; p = 0.05). Less time expressing anger was associated with greater health anxiety (r = -0.37; p = 0.03), greater symptoms of anxiety (r = -0.46; p < 0.01), more catastrophic thinking (r = -0.38; p = 0.03), and greater symptoms of depression (r = -0.42; p = 0.01). More time expressing surprise was associated with less health anxiety (r = -0.44; p < 0.01) and symptoms of depression (r = -0.52; p < 0.01). More time expressing fear was associated with less kinesiophobia (r = -0.35; p = 0.04). More time expressing disgust was associated with less catastrophic thinking (r = -0.37; p = 0.03) and less health anxiety (GAD-2; r = -0.42; p = 0.02) and symptoms of depression (r = -0.44; p < 0.01). There was no association between a clinicians' facial expression of emotions and patient experience with patient-clinician interactions. The ability to measure a patient's mindset on the clinician's face confirms that clinicians are registering the psychological aspects of illness, whether they are consciously aware of them or not. Future research involving larger cohorts of patients, mapping clinician-patient interactions during consultation, and more sophisticated capture of nonverbal and verbal cues, including a broader range of emotional expressions, may help translate this innovation from the research setting to clinical practice. Tools for measuring emotion through facial recognition could be used to train clinicians to become aware of the psychological aspects of health and to coach clinicians on effective communication strategies both for gentle reorientation of common misconceptions as well as for appropriate and timely diagnosis and treatment of psychological distress.

Health Care Utilization for Musculoskeletal Issues Duringthe Prediagnosis Period in Psoriatic Arthritis: APopulation-Based Study.

Information about the prediagnosis period in psoriatic arthritis (PsA) is limited. The present study was undertaken to compare health care utilization related to musculoskeletal issues during a 5-year period prior to the diagnosis of PsA versus that of subjects with no prior inflammatory arthritis within a primary care setting. We conducted a population-based, matched cohort study using electronic medical records and administrative data in Ontario, Canada. Age- and sex-matched cohorts of PsA patients and comparators from the same family physicians were assembled. Comparators were not allowed to have prior spondyloarthritis, ankylosing spondylitis, or rheumatoid arthritis billing code diagnoses. The study outcomes included health care utilization and costs related to nonspecific musculoskeletal issues during a 5-year period prior to the index date. We studied 462 PsA patients and 2,310 matched comparators. The odds ratio (OR) related to visiting a primary care physician for nonspecific musculoskeletal issues in patients with PsA was 2.14 (95% confidence interval 1.73-2.64) in the year immediately preceding the index date and was similarly elevated up to 5 years prior. The OR related to using other musculoskeletal-related health care services, including musculoskeletal specialists visits, joint injections, joint imaging, and emergency department visits, was higher in PsA as early as 5 years preceding the index date. Total and musculoskeletal-related health care costs prior to the index date were higher for patients with PsA versus comparators. A prodromal PsA phase characterized by nonspecific musculoskeletal symptoms may exist. Further study is needed to determine if this represents a window for earlier diagnosis of PsA.

People Prefer to Continue with Painful Activities Even if They Lead to Earlier Surgery.

The degree to which physical activity results in arthritis progression is unknown, but it probably is less than most people believe. But the belief that painful activity is harmful has notable associations both with greater pain intensity and greater activity intolerance among people seeking care for painful conditions such as osteoarthritis. If there were evidence that people not seeking care would prefer to accommodate a painful cherished activity, even if such accommodation is harmful, this might remind surgeons that many people seeking their care also hold this value. Care strategies could be designed to help people reconnect with this value by guiding them to an appropriate weighting of the potential benefits and the potential harms of painful activity. (1) What degree of harm (measured as a decrease in the number of years before reconstructive surgery) are people willing to trade to continue a cherished activity? (2) What factors are associated with the chosen number of years? (3) What percentage of patients is willing to trade harm to the joint (presented as surgery 3 years earlier) to continue their cherished activity? (4) What factors are associated with the choice to trade harm for continued activity? We performed an online, survey-based, time trade-off experiment using a crowdsourcing website that allows users to pay volunteers to complete surveys. The survey was closed when the prespecified number of surveys was obtained. The experiment measured personal and psychological factors associated with the willingness to accommodate harmful painful activity to continue cherished activities among people not currently troubled by the condition, an approach favored in trade-off studies. Large crowdsourcing survey studies may not represent the general population, but they have sufficient diversity to determine factors associated with responses. Participants (539 total, 289 men and 250 women with a mean age of 33 ± 11 years) completed validated measures of symptoms of anxiety and depression, activity tolerance, an 11-point ordinal measure of pain intensity, and three validated questionnaires addressing common misconceptions about pain. To answer our first and second questions, we calculated the harm (measured as a decrease in the number of years before reconstructive surgery) that people were willing to trade to continue their cherished activity, and then we used multiple linear regression to identify factors associated with the number of years. To answer the third and fourth questions, we calculated the percentage of patients who would choose to trade harm to the joint (surgery 3 years earlier) to continue their cherished activity and then we used multiple logistic regression to identify factors associated with the choice to trade harm for activity. Participants were willing to trade harm in the form of more rapid disease progression leading to surgery a mean of 4.5 ± 3.6 years earlier to continue a cherished activity. Controlling for personal and psychological factors, a greater number of years people were willing to trade was associated with slightly greater bodily pain intensity (r = 0.11; p = 0.01). Seventy-six percent (410 of 539) of participants were willing to trade harm in the form of needing surgery 3 years earlier to continue their cherished activity. Controlling for personal and psychological factors, a choice to trade earlier surgery for continued activity was associated with an income greater than USD 50,000 per year (odds ratio 2.07 [95% confidence interval 1.17 to 3.65]; p = 0.01) and greater fear of painful movement (OR 1.07 [95% CI 1.01 to 1.15]; p = 0.04). People are relatively willing to accommodate pain to continue a cherished activity, even if it causes harm. Musculoskeletal specialists can incorporate strategies to help people seeking care to revitalize their inherent level of willingness to accommodate painful activity. One strategy might be to attend to an appropriate weighting of the potential benefits and the potential harms of painful activity. Level II, prognostic study.

Meniscal lesion detection and characterization in adult knee MRI: A deep learning model approach with external validation.

Evaluation of a deep learning approach for the detection of meniscal tears and their characterization (presence/absence of migrated meniscal fragment). A large annotated adult knee MRI database was built combining medical expertise of radiologists and data scientists' tools. Coronal and sagittal proton density fat suppressed-weighted images of 11,353 knee MRI examinations (10,401 individual patients) paired with their standardized structured reports were retrospectively collected. After database curation, deep learning models were trained and validated on a subset of 8058 examinations. Algorithm performance was evaluated on a test set of 299 examinations reviewed by 5 musculoskeletal specialists and compared to general radiologists' reports. External validation was performed using the publicly available MRNet database. Receiver Operating Characteristic (ROC) curves results and Area Under the Curve (AUC) values were obtained on internal and external databases. A combined architecture of meniscal localization and lesion classification 3D convolutional neural networks reached AUC values of 0.93 (95% CI 0.82, 0.95) for medial and 0.84 (95% CI 0.78, 0.89) for lateral meniscal tear detection, and 0.91 (95% CI 0.87, 0.94) for medial and 0.95 (95% CI 0.92, 0.97) for lateral meniscal tear migration detection. External validation of the combined medial and lateral meniscal tear detection models resulted in an AUC of 0.83 (95% CI 0.75, 0.90) without further training and 0.89 (95% CI 0.82, 0.95) with fine tuning. Our deep learning algorithm demonstrated high performance in knee menisci lesion detection and characterization, validated on an external database.

Can Crafted Communication Strategies Allow Musculoskeletal Specialists to Address Health Within the Biopsychosocial Paradigm?

Musculoskeletal specialists who attempt to discuss the connection between mental health (thoughts and emotions) and physical health (symptom intensity and activity tolerance) with patients, may fear that they risk offending those patients. In a search for language that creates comfort with difficult conversations, some specialists favor a biomedical framework, such as central sensitization, which posits abnormal central neuron activity. Without addressing the relative accuracy of mind- or brain-based conceptualizations, we addressed crafted and practiced communication strategies as conversation starters that allow specialists to operate within a biopsychosocial framework without harming the relationship with the patient. We measured (1) patient resonance with various explanations of the mind-body connection, including examples of both mind- and brain-based communication strategies, and (2) factors associated with resonance and emotional reactions to the explanations. In this cross-sectional study, all adult new and returning patients who were literate in English and who attended several musculoskeletal specialty offices were invited to complete questionnaires addressing reactions to one of seven explanations of the mind-body connection assigned using a random number generator. Acknowledging that the relative accuracy of mind-based and nerve- or brain-based strategies are speculative, we developed the following conversation starters: two explanations that were cognitively framed ("the mind is a great story teller"; one positively framed and one negatively framed), two emotionally framed explanations ("stressed or down"; one positively framed and one negatively framed), one mentioning thoughts and emotions in more neutral terms ("mind and body work together … thoughts and emotions affect the way your body experiences pain"), and two biomedical neurophysiology-based explanations ("nerves get stuck in an over-excited state" and "overstimulated nerves"), all crafted with the assistance of a communication scholar. It was unusual for people to decline (although the exact number of those who did was not tracked) and 304 of 308 patients who started the questionnaires completed them and were analyzed. In this sample, 51% (155 of 304) were men, and the mean ± SD age was 49 ± 17 years. Reactions were measured as resonance (a 1 to 5 Likert scale regarding the degree to which the stated concept aligns with their understanding of health and by inference is a comfortable topic of discussion) and self-assessment manikins using circled figurines to measure feelings of happiness (frowning to smiling figures), stimulation/excitement (a relaxed sleepy figure to an energized wide-eyed figure), and security/control (small to large figures). These are commonly used to quantify the appeal and emotive content of a given message. Patients also completed surveys of demographics and mental health. Multilevel multivariable linear regression models were constructed to assess factors associated with resonance, happiness, excitement, and control. Controlling for potential confounding variables such as demographics and mental health measures, a relatively neutral biopsychosocial explanation ("mind and body work together") had the greatest mean resonance (4.2 ± 0.8 versus 3.8 ± 0.9 for the other explanations; p < 0.01) and the largest regression coefficient for resonance (0.78 [95% confidence interval 0.41 to 1.15]). The next-most-resonant explanations were biomedical ("excitable nerves", "over-excited state"). Biopsychosocial explanations that mention stress, distress, or cognitive bias ("mind is a great storyteller") had lower resonance. People with greater unhealthy cognitive bias regarding pain (more catastrophic thinking) were less comfortable with all the explanations (lower resonance, regression coefficient -0.03 [95% CI -0.06 to -0.01]). Emotional reactions were relatively comparable with the exception that people felt less control and security with specific explanations such as "excitable nerves" and "mind is a great storyteller." Crafted communication strategies allow musculoskeletal specialists to address health within the biopsychosocial paradigm without harming their relationship with the patient. Musculoskeletal specialists may be the first clinicians to notice mental health opportunities. It may be helpful for them to develop and practice effective communication strategies that make mental health a comfortable topic of discussion.

P195 Using remote access musculoskeletal consultations within a cystic fibrosis specialist physiotherapy service: a pilot

During COVID-19, musculoskeletal (MSK) physiotherapists were redeployed to supplement acute staffing. Virtual clinics (VC) were used by the cystic fibrosis (CF) MDT to assess and monitor patients. Objectives: To scope benefits of providing MSK physiotherapy to allow pwCF to self-manage their condition and improve their quality of life (QOL). Methods: VC for MSK pain were offered for 6 weeks. Patient satisfaction and perceived resolution of symptoms was assessed. Results: 15 patients had an average of 1.5 treatment sessions. MSK problems included peripheral joint pain n = 12;spine n = 2 and TMJ. 91% of pwCF were seen within 3 days of referral with remainder seen within 1 week. 55% responded to a satisfaction survey. 83% of pwCF felt a 58% improvement in symptoms. 50% felt the support received was sufficient with 50% requiring additional follow-up. Future access to CF MSK services was considered favourably. 33% stated a preference for face-to-face consultation, with 50% finding VC to be a ‘convenient alternative’. PwCF have an increased prevalence of spinal deformities such as kyphosis and scoliosis, the same prevalence of MSK pain as age-matched controls and pain in pwCF rising with age and associated co-morbidities. 94% of pwCF may experience pain limiting airway clearance and subsequent QOL. PwCF often describe the negative impact pain has on their ability to stay active and function in daily life. UK national standards of care recommend that ‘all individuals with CF should be screened for MSK signs and symptoms, with referral pathways to access MSK specialists where appropriate’ suggesting that MSK specialist input within CF centres would be ideal. In Glasgow, there is currently no specialist CF MSK physiotherapy provision and local specialist services have a current waiting list of 44 weeks. Conclusion: This study demonstrated that pwCF feel specialist CF MSK input is valuable and significantly reduced their pain within a short period of time, thus maintaining their QOL.

Difficult life events affect lower extremity illness.

Given the relationship between psychological distress and activity tolerance (capability), a stressful life event might diminish accommodation, increase symptoms, and induce a person to seek specialty care. As a first step to investigate this possibility, this study addressed whether difficult life events are associated with greater activity intolerance and pain intensity. A cohort of 127 patients seeking specialty care for lower extremity symptoms completed questionnaires that inquired about difficult life events within the last 12months as derived from the Holmes Rahe Life Stress Inventory, and recorded pain intensity on an 11-point ordinal scale, activity tolerance [Patient Reported Outcomes Measurement Information System Physical Function Computer Adaptive Test (CAT)], symptoms of anxiety (GAD-2; 2 item version of the Generalized Anxiety Disorder questionnaire), symptoms of depression (PROMIS Depression CAT), self-efficacy when in pain (Pain Self-Efficacy Questionnaire, 2 question version), and demographics. The treating clinician indicated if the disease was established (e.g. arthritis) or relatively new (e.g. sprain/strain). Bivariate and multivariable analyses sought factors associated with activity intolerance and pain intensity. Greater activity intolerance was associated with difficult life events in bivariate analyses (t = 2.13, MD = 3.18, 95% C.I. = 0.22-6.13, p = 0.04) and in multivariable analyses that excluded symptoms of depression. Greater pain intensity was not associated with difficult life events, but was associated with surgeon rating of established disease (β = 1.20, 95% C.I. = 0.33-2.08, p < 0.01), greater symptoms of anxiety (MD = 3.35, s = 1.72; ρ = 0.30, p < 0.01), and less education (β = - 1.06, 95% C.I. = - 1.94- - 0.18, p = 0.02) (no college degree). When a musculoskeletal specialist identifies less activity tolerance (less capability) than anticipated for a given injury or pathology, they can anticipate a potential difficult life event, and expect alleviation of symptoms and improved capability as the stress is ameliorated with time and support. Specialists can be prepared to direct people to community or professional support if requested.

3D Imaging for Hindfoot Alignment: A Comparative Study between MRI and Weight Bearing CT

Category:Hindfoot; OtherIntroduction/Purpose:Hindfoot malalignment is a common finding in multiple foot and ankle pathologies. In clinical practice, it is usually quantified through traditional weight bearing radiographs or, more recently, through cone beam weight bearing CT (CB- WBCT), which overcomes issues related to two-dimensional imaging. Interestingly, a few studies have suggested that hindfoot alignment can also be accurately assessed using non-weight bearing magnetic resonance imaging (MRI). The purpose of this study was to compare measurements of hindfoot alignment on non-weight bearing ankle MRI and CB-WBCT and to establish if there was any correlation.Methods:In this Level III retrospective comparative study, a database review identified 51 feet in 47 patients (27 males, 20 females; mean age of 45 (range 13-79)) which had both CB-WBCT and MRI scans on the same day as part of standard care at our specialist tertiary referral Foot and Ankle Unit. Hindfoot alignment was assessed by independent Consultant Musculoskeletal specialists. The foot ankle offset (FAO), calcaneal offset (CO) and hindfoot alignment angle (HA) were assessed on CB-WBCT using dedicated software. The tibiocalcaneal angle (TCA) and calcaneofibular ligament angle (CFLA) were assessed on non-weight bearing MRI. Pearson correlation was used to evaluate the correlation between these measurements.Results:We found a statistically significant positive correlation between TCA on non-weight bearing MRI and each measurement on CB-WBCT (Pearson correlation for TCA and FAO: 0.42, p=0.003; for TCA and CO: 0.46, p=0.001; and for TCA and HA: 0.40, p=0.005).We also demonstrated a moderate-to-low negative but significant correlation between CFLA and CO (Pearson correlation: -0.35; p=0.03). Conversely, the negative correlation between CFL and FAO (Pearson correlation: -0.29; p=0.07) and CFL with HA (Pearson correlation: -0.26; p=0.11) did not reach statistical significance.Conclusion:Weight bearing three-dimensional imaging has shown high degrees of accuracy and reproducibility for hindfoot alignment. The significant correlation between TCA on non-weight bearing MRI and hindfoot alignment measurements on CB- WBCT suggests that TCA should be reported during routine ankle MRI in order to put into context some of the soft-tissue findings. The CFLA shows a less significant negative correlation.

Accessory Soleus Muscle: Two Case Reports with a Completely Different Presentation Caused by the Same Entity

Accessory soleus muscle (ASM) is a rare supernumerary anatomical variant that commonly presents as a posteromedial ankle swelling, which may become painful during physical activity. As it may mimic a soft tissue tumor, it is essential to differentiate this condition from ganglion, lipoma, hemangioma, synovioma, and sarcoma. However, ASM may also present with a painful syndrome, characterized by pain and paresthesia of the ankle and foot, mimicking the tarsal tunnel syndrome (TTS). Two cases of ASM are presented in this article. The first case had a typical presentation with painful posteromedial ankle swelling. After the initial assessment, the diagnosis was confirmed by magnetic resonance imaging (MRI), and ASM was treated by complete resection. The second case presented with pain and paresthesia in the right ankle and foot, but no swelling was noticeable. It was initially misdiagnosed by a rheumatologist and afterward overlooked on an MRI by a musculoskeletal radiology specialist and therefore mistreated by numerous physicians before being referred to our outpatient clinic. After further assessment, the diagnosis has been confirmed, and ASM was treated by complete resection combined with tarsal tunnel decompression. To the best of our knowledge, this is the first case reported in which ASM caused symptoms but presented without posteromedial swelling. This might be due to a proximally positioned belly of the ASM, followed by a tendinous insertion on the medial side of the calcaneus.

Differences in Self-Reported Physical and Behavioral Health in Musculoskeletal Patients Based on Physician Gender.

Differences in patient-physician interactions based on physician gender have been demonstrated. However, the association between patients' self-perceived health and their decision to see a female versus male physician is still unclear. To determine if self-reported physical or behavioral health is different in musculoskeletal patients who present to female vs male physicians. We hypothesized that patients who present to female physicians report worse physical and behavioral health. Cross-sectional study. Tertiary academic medical center. Consecutive 21 980 adult patients who presented to a musculoskeletal medicine specialist for initial evaluation of a musculoskeletal condition between April 1, 2016 and November 1, 2017. Physical Function, Pain Interference, Anxiety, and Depression Computer Adaptive Test domains of the Patient-Reported Outcomes Measurement Information System (PROMIS). The primary study outcome was the mean difference (MD) in PROMIS scores by physician gender. Patients who presented to female physicians self-reported slightly worse health in all domains: Physical Function (female physicians 40.2, male physicians 42.4, MD -2.1; 95% confidence interval [CI] -2.5 to -1.8), Pain Interference (female physicians 61.6, male physicians 60.4, MD 1.3 [1.0-1.5]), Anxiety (female physicians 52.5, male physicians 51.4, MD 1.1 [0.8-1.5]), and Depression (female physicians 47.5, male physicians 46.2, MD 1.3 [0.9-1.6]) (all P < .001). Patients who presented to female physicians were also slightly younger (51.9 vs 52.4 years, P = .034) and more likely to be female (63% vs 56%, P < .001). Patients who presented to female physicians self-reported slightly worse physical and behavioral health compared to those patients who presented to male physicians. Further investigation into this finding may provide insight into drivers of patients' preferences, which may enable physicians of both genders to optimize patient care.

OP0318 THE ROLE OF DUAL ENERGY COMPUTED TOMOGRAPHY (DECT) IN THE DIFFERENTIATION OF GOUT AND CALCIUM PYROPHOSPHATE DEPOSITION DISEASE

Background:Differentiation of gout and calcium pyrophosphate deposition disease (CPPD) is sometimes difficult as patients often present with a similar clinical picture. Arthrocentesis and subsequent polarization microscopy (PM) remains the gold standard but novel diagnostic approaches such as non-invasive dual energy computed tomography (DECT) have recently been validated for gout. Currently, limited data is available on DECT in patients with CPPD.Objectives:To analyse the diagnostic impact of DECT in gout and CPPD when compared to the gold standard of PM. We further compared the results of PM to ultrasound (US), conventional radiographs (CR), and suspected clinical diagnosis (SCD). Additionally, 15 laboratory parameters were analysed.Methods:Twenty-six patients diagnosed with gout (n = 18) or CPPD (n = 8) who received a DECT and underwent arthrocentesis were included. Two independent readers assessed colour coded, as well as 80 and 120 kV DECT images for signs of monosodium urate (MSU) crystals or CPP deposition. US and CR from the patient’s initial visit along with the SCD were also compared to PM. US examinations were performed by certified musculoskeletal ultrasound specialists. The association of up to 15 laboratory parameters such as uric acid, thyroid stimulating hormone, and C-reactive protein (CRP) with the PM results was analysed.Results:Sensitivity of DECT for gout was 67% (95% CI 0.41-0.87) with a specificity of 88% (95% CI 0.47-1.0). Concerning CPPD, the sensitivity and specificity of DECT was 63% (95% CI 0.25-0.91) and 83% (95% CI 0.59-0.96) respectively. US had the highest sensitivity of 89% (95% CI 0.65-0.99) with a specificity of 75% (95% CI 0.35-0.97) for gout, while the sensitivity and specificity for CPPD were 88% (95% CI 0.47-1.0) and 89% (95% CI 0.65-0.99) respectively. The SCD had the second highest sensitivity for gout at 78% (95% CI 0.52-0.94) with a comparable sensitivity of 63% (95% CI 0.25-0.92) for CPPD. Uric acid levels were elevated in 33% of gout patients and 25% of CPPD patients. While elevated CRP levels were observed in 59% of gout patients and in 88% of CPPD patients, none of the 15 analysed laboratory parameters were found to be significantly linked.Conclusion:DECT provides a non-invasive diagnostic tool for gout but might have a lower sensitivity than suggested by previous studies (67% vs 90%1). DECT sensitivity for CPPD was 63% (95% CI 0.25-0.91) in a sample group of eight patients. Both US and the SCD had higher sensitivities than DECT for gout and CPPD. Further studies with larger patient cohorts are needed in order to determine the diagnostic utility of DECT in CPPD.

Paediatric musculoskeletal (MSK) triage in the community - RightPath - a pilot study

Purpose: We have developed children and young people (CYP) community-based triage (called RightPath) based on a validated adult MSK model developed by Pennine MSK Partnership Ltd (PMSKP). RightPath aims to use paediatric physiotherapists to identify CYP with MSK pathology and triage them to the appropriate service (rheumatology, orthopaedics, or urgent care), managing those who do not need specialist referral appropriately within the community (by physiotherapists and podiatrists). Triage and referral guidance was developed in partnership with MSK specialists and primary care. The pilot tested safety, feasibility, acceptability, and transferability of triage in the community in two UK localities with emphasis on the educational requirements of the triage guidance for healthcare professionals who may not be expert in CYP MSK disease.

3D patella and femur bone shape modeling for patella instability patients

Purpose: Lateral patellar instability is a common knee problem that accounts for more than 10% of the musculoskeletal specialist office visits. It causes significant functional impairment to the young and active patient population. Dislocation and relocation of the patella loads cartilage traumatically, resulting in cartilage degeneration which can be consistently detected with MRI within 10 years from the initial instability episode. Moreover, patellar instability increases the risk of developing osteoarthritis by a factor of 8.

Joint Design with Providers of Clinical Decision Support for Value-Based Advanced Shoulder Imaging.

Provider orders for inappropriate advanced imaging, while rarely altering patient management, contribute enough to the strain on available health care resources, and therefore the United States Congress established the Appropriate Use Criteria Program. To examine whether co-designing clinical decision support (CDS) with referring providers will reduce barriers to adoption and facilitate more appropriate shoulder ultrasound (US) over magnetic resonance imaging (MRI) in diagnosing Veteran shoulder pain, given similar efficacies and only 5% MRI follow-up rate after shoulder US. We used a theory-driven, convergent parallel mixed-methods approach to prospectively (1) determine medical providers' reasons for selecting MRI over US in diagnosing shoulder pain and identify barriers to ordering US, (2) co-design CDS, informed by provider interviews, to prompt appropriate US use, and (3) assess CDS impact on shoulder imaging use. CDS effectiveness in guiding appropriate shoulder imaging was evaluated through monthly monitoring of ordering data at our quaternary care Veterans Hospital. Key outcome measures were appropriate MRI/US use rates and transition to ordering US by both musculoskeletal specialist and generalist providers. We assessed differences in ordering using a generalized estimating equations logistic regression model. We compared continuous measures using mixed effects analysis of variance with log-transformed data. During December 2016 to March 2018, 569 (395 MRI, 174 US) shoulder advanced imaging examinations were ordered by 111 providers. CDS "co-designed" in collaboration with providers increased US from 17% (58/335) to 50% (116/234) of all orders (p < 0.001), with concomitant decrease in MRI. Ordering appropriateness more than doubled from 31% (105/335) to 67% (157/234) following CDS (p < 0.001). Interviews confirmed that generalist providers want help in appropriately ordering advanced imaging. Partnering with medical providers to co-design CDS reduced barriers and prompted appropriate transition to US from MRI for shoulder pain diagnosis, promoting evidence-based practice. This approach can inform the development and implementation of other forms of CDS.

PROMIS Physical and Emotional Health Scores Are Worse in Musculoskeletal Patients Presenting to Physiatrists than to Other Orthopedic Specialists.

Physiatrists' unique training in person-centered biopsychosocial management of complex problems may influence musculoskeletal patients' expectations and self- and/or physician-referral patterns to physiatrists. Consequently, average patient complexity and need for multi-disciplinary services may be increased in physiatric patients. To compare musculoskeletal patients' self-reported physical and emotional health according to provider specialty. Researchers tested the null hypothesis that there is no significant difference in Patient-Reported Outcomes Measurement Information System (PROMIS) scores between patients who present to physiatrists in comparison to other musculoskeletal specialists. Cross-sectional study. Orthopedic department of a tertiary academic medical center. Participants included 31 791 new adult patients (mean age 52.6 ± 16.2 years) who presented for initial elective evaluation of a musculoskeletal problem by an orthopedic surgeon or sports medicine trained emergency medicine, family medicine, pediatric, or physiatric physician. Patients completed the PROMIS computer adaptive test (CAT) Physical Function, Pain Interference, Anxiety, and Depression domains at department check-in prior to the physician encounter. Score differences by provider type were assessed using Wilcoxon rank-sum tests. Mean PROMIS score in each domain subdivided by physiatric, surgical, and other nonsurgical provider type. In total, 2081 patients presented to physiatrists, 28 267 presented to surgeons, and 1443 presented to other nonsurgical providers. For each respective provider type, average PROMIS scores were Physical Function 38.9 ± 8.2, 41.5 ± 9.5, and 43.5 ± 8.2; Pain Interference 62.6 ± 7.2, 60.9 ± 7.7, and 59.2 ± 6.8; Anxiety 54.5 ± 10.4, 51.9 ± 10.6, and 49.8 ± 9.8; and Depression 49.3 ± 10.4, 47.0 ± 10.0, and 44.2 ± 8.7. Physiatric patients had significantly worse average scores for all domains compared to surgical (P < .001) and other nonsurgical patients (P < .001). Average PROMIS Physical Function, Pain Interference, Anxiety, and Depression scores were worse in musculoskeletal patients who presented to physiatrists in comparison to surgical or other nonsurgical providers. This suggests that some patients who choose to see or are referred to see physiatrists may have more or be more willing to endorse having biopsychosocial impairments. III.

Glenohumeral osteoarthritis: frequency of underlying diagnoses and the role of arm dominance-a retrospective analysis in a community-based musculoskeletal practice.

Patients with shoulder pain are commonly seen in adult primary care, and are typically referred to musculoskeletal specialists when their symptoms are persistent. Rotator cuff disorders (RCD) most commonly underlie non-traumatic shoulder pain in adults, and glenohumeral osteoarthritis (GHOA) has been considered to be relatively uncommon (Nakagawa et al., J Shoulder Elb Surg 8:580-584, 1999). Our impression has been that GHOA affects significant numbers of patients, is less well studied, and may be under recognized. Among adults referred to a musculoskeletal practice for shoulder pain evaluation, wedetermined the relative numbers of patients with a clinical diagnosis of RCD and GHOA by age and by gender, assessed the role of handedness in GHOA, and the proportion of patients with underlying conditions (versus primary or idiopathic GHOA). We also assessed the frequency of progression to operative management over a defined time interval. This is a retrospective case series of patients presenting to a musculoskeletal referral practice for shoulder pain. Patients with a clinical diagnosis of GHOA were identified with electronic medical records, and then assessed for demographic data, physical measures, comorbidities, and progression to surgical intervention within 2years. Among non-traumatic shoulder pain patients presenting to our practice during a 9-month period in 2013, RCD was diagnosed in 984 patients, and GHOA was diagnosed in 209 patients. 152 of the GHOA patients (73%) had primary (idiopathic) GHOA, without associated inflammatory conditions or cuff arthropathy. Primary GHOA affected the dominant arm in 38.7%, the non-dominant arm in 33.8%, and was bilateral in 27.5%. Patients diagnosed with primary GHOA were older than those with RCD (69.8 ± 12.2 vs 57.1 ± 15.1; p = 0.0001). Women represented 54% of cases of primary GHOA, and their presentation age was older than men (72.9 ± 11.2 vs 66.1 ± 12.4; p = 0.0005). Primary GHOA patients had a mean BMI of 31.0 ± 6.3, 48.7% had hyperlipidemia and 57.2% had hypertension. 24.3% were treated surgically within 2years of follow-up. GHOA is a significant cause of shoulder pain in older age groups, and the majority of these patients have primary (idiopathic) GHOA. Primary GHOA affects dominant and non-dominant arms at similar rates, suggesting that anatomical and/or systemic factors are more important than overuse in GHOA pathogenesis. Given the prominence of GHOA in older age groups, changes in population demographics, and limitations of non-operative treatment, continued increases in shoulder replacement surgery are likely. Efforts to further understand GHOA pathogenesis and develop new, more effective therapies are advocated.

Intra-Rater reliability of the Functional Movement Screen (FMS) amongst NHS Physiotherapists

Objectives: The primary aim of this study was to evaluate the intra-rater reliability of the FMS amongst a group of novice National Health Service (NHS) Physiotherapists. The secondary objective was to establish if Intra-rater reliability differed between non-specialist rotational Physiotherapists and Physiotherapists working within the musculoskeletal (MSk) setting. Design: Reliability Study. Method: Forty participants with no recent MSk injury were video recorded completing the 7 component FMS tests. Six NHS Physiotherapists with no previous experience using the FMS attended a 2 hour training programme delivered by a certified FMS practitioner. Raters then viewed and scored videos of the 40 participants completing the FMS. Results: The intra-rater reliability of FMS composite scores was Excellent (mean ICC of 0.91 (95% CI 0.81-0.96)). The non-specialist rotational Physiotherapist group demonstrated Good-Excellent intra-rater reliability (ICC 0.9; 95% CI 0.79-0.95). Specialist MSk Physiotherapists demonstrated Excellent intra-rater reliability (ICC 0.92; 95% CI 0.84-0.96). Intra-rater reliability of the 7 component tests of the FMS ranged from Poor-Excellent (KW 95% CI 0.11-0.98). Conclusion: Among novice NHS Physiotherapists, the FMS composite score demonstrated Excellent intra-rater reliability. MSk specialists were found to demonstrate a marginally superior level of intra-rater agreement compared to non-specialist rotational Physiotherapists; however this is likely to be negligible in a clinical context. Clinical specialism also appears to have little impact on the intra-rater reliability of FMS components with both groups of raters achieving a Poor-Excellent level of agreement.

Reliability of musculoskeletal ultrasound imaging to measure supraspinatus tendon thickness in healthy subjects.

[Purpose] The purpose of this study was to assess intra-rater and inter-rater reliability of musculoskeletal ultrasound (MSKUS) as a tool to measure supraspinatus tendon thickness in healthy subjects. [Subjects and Methods] Twenty healthy subjects were assessed in similar sitting position. Two experienced musculoskeletal ultrasound specialists measured supraspinatus tendon thickness. Tendon was measured twice in one day by each of two raters with an interval of one hour for within day reliability and was re-measured following one week for between days reliability. Data analysis was performed using the intraclass correlation coefficient (ICC) and standard error of measurement (SEM). [Results] Results reflected excellent within day intra-rater and inter-rater reliability with Mean ± standard deviation (SD)=5.14 ± 0.83 and 5.17 ± 0.78, ICC (2,1)=0.89–0.93 and ICC (2,2)=0.98 (0.95−0.99) and SEM=0.18–0.18 and 0.17 while between days intra-rater rater and inter-rater reliability with Mean ± SD=5.14 ± 0.83 and 5.17 ± 0.78, ICC(2,1)=0.88–0.90 and ICC(2,2)=0.95 (0.88−0.98), SEM=0.17–0.38 and 0.17 [Conclusion] The results of the current study indicate that MSKUS is a reliable tool for measuring supraspinatus tendon thickness in healthy subjects.
