Psychometric properties of the Disability of Arm Shoulder and Hand (DASH) in subjects with frozen shoulder: a reliability and validity study.

BACKGROUND: Frozen Shoulder (FS) is a painful condition characterized by severe pain and progressive restriction of shoulder movement, leading to functional impairment and reduced quality of life. While different Patient Reported Outcome Measurements (PROMs) tools exist for assessing shoulder diseases, few specific PROMs are validated for FS patients. PURPOSE: This study aims to assess the psychometric properties of the Disability of Arm, Shoulder, and Hand (DASH) questionnaire in FS patients. METHODS: One hundred and twenty-four subjects (mean ± SD age = 55.4 ± 7.9 years; 55.6% female) diagnosed with FS were included and completed the DASH questionnaire, the Numerical Pain Rating Scale (NPRS), the Shoulder Pain and Disability Index (SPADI), and the Short-Form Health Survey 36 (SF-36). Floor or ceiling effects were investigated. Structural validity was analysed through a unidimensional Confirmatory Factor Analysis (CFA), internal consistency through Cronbach's alpha, test-retest reliability through the Intraclass Correlation coefficient (ICC), measurement error through the Standard Error of Measurement (SEM), and the Minimum Detectable Change (MDC), and construct validity through the hypothesis testing with the correlation with the other outcome measures used. RESULTS: No floor or ceiling effects were observed. CFA confirmed a one-factor structure after addressing local item dependency (Root Mean Square Error of Approximation = 0.055; Standardized Root Mean Square Residual = 0.077; Comparative Fit Index = 0.970; Tucker-Lewis Index = 0.968). Cronbach's alpha was high (= 0.951), and test-retest reliability was excellent (ICC = 0.999; 95% CI: 0.998-1.000). SEM was equal to 0.5 points, and MDC to 1.5 points. Construct validity was considered satisfactory as 80% of the a-priori hypotheses were met. CONCLUSION: The DASH questionnaire demonstrated good psychometric properties in FS patients, supporting its use as a valuable tool for assessing the impact of FS in clinical and research settings.

[OLECRANON BURSITIS].

INTRODUCTION: The olecranon bursa is a pocket-like structure located at the posterior aspect of the elbow that is responsible for the smooth movement of the surrounding tissues. Frequently, it is the source of elbow pain due to an inflammation which may be caused by local injury or penetration of bacteria through the skin. This can lead to an initial acute and possibly a late chronic inflammation. Chronic inflammation may originate from systemic diseases such as gout and rheumatoid arthritis as well. The treatment of olecranon bursitis may be conservative (non-surgical) or surgical. Recently, there is more supporting evidence for the use of conservative management over surgical intervention in treating olecranon bursitis.

American Cancer Society Head and Neck Cancer Survivorship Care Guideline.

Answer questions and earn CME/CNE The American Cancer Society Head and Neck Cancer Survivorship Care Guideline was developed to assist primary care clinicians and other health practitioners with the care of head and neck cancer survivors, including monitoring for recurrence, screening for second primary cancers, assessment and management of long-term and late effects, health promotion, and care coordination. A systematic review of the literature was conducted using PubMed through April 2015, and a multidisciplinary expert workgroup with expertise in primary care, dentistry, surgical oncology, medical oncology, radiation oncology, clinical psychology, speech-language pathology, physical medicine and rehabilitation, the patient perspective, and nursing was assembled. While the guideline is based on a systematic review of the current literature, most evidence is not sufficient to warrant a strong recommendation. Therefore, recommendations should be viewed as consensus-based management strategies for assisting patients with physical and psychosocial effects of head and neck cancer and its treatment.

Is there an association between breast cancer and incident adhesive capsulitis of the shoulder? A retrospective cohort study from Germany.

PURPOSE: Preliminary data suggest that women with breast cancer are at particularly high risk of adhesive capsulitis of the shoulder. Therefore, this study aimed to investigate the potential association between breast cancer and adhesive capsulitis in adults from Germany. METHODS: This retrospective cohort study included all women aged ≥ 18 years who were diagnosed for the first time with breast cancer in one of 1,274 general practices in Germany between January 2000 and December 2018 (index date). Women without breast cancer were matched (1:1) to those with breast cancer using a propensity score based on age at the index date, index year, and the average number of medical consultations per year during the follow-up. In women without breast cancer, the index date was a randomly selected visit date between 2000 and 2018. The association between breast cancer and the 10-year incidence of adhesive capsulitis was studied using Kaplan-Meier curves and a Cox regression model adjusted for age and several comorbidities. RESULTS: There were 52,524 women included in this study (mean [SD] age 64.2 [12.9] years). The 10-year incidence of adhesive capsulitis was 3.6% in both the group with and the group without breast cancer (log-rank p-value = 0.317). The Cox regression analysis further showed no significant association between breast cancer and adhesive capsulitis (HR = 0.96, 95% CI = 0.86-1.08). CONCLUSION: In this sample of women from Germany, breast cancer was not significantly associated with adhesive capsulitis. Although the present preliminary findings are reassuring, general practitioners should regularly assess shoulder function in breast cancer survivors.

Comparison of corticosteroid injection, physiotherapy and combined treatment for patients with chronic subacromial bursitis - A randomised controlled trial.

OBJECTIVE: To investigate whether combination of corticosteroid subdeltoid injections and physiotherapy was more effective than either treatment alone in chronic subacromial bursitis. DESIGN: Prospective, three-arm randomised controlled trial. SETTING: Rehabilitation department of an academic hospital. SUBJECTS: Patients with chronic subacromial bursitis. INTERVENTIONS: Patients were divided into corticosteroid injection (N = 36), physiotherapy (N = 40) and combined (N = 35) groups. Two corticosteroid subdeltoid injections in corticosteroid group, 8-week physical therapy emphasising on therapeutic exercise in physiotherapy group, and combined both treatments in combined group. MAIN OUTCOME MEASURES: The primary outcome measures were pain visual analogue scale and Shoulder Pain and Disability Index at 8 weeks after finishing treatment. The secondary outcome measures were active range of motion, Shoulder Disability Questionnaire, Western Ontario Rotator Cuff Index, patient's evaluation of treatment effect, and symptom recurrence. RESULTS: Group comparison showed significant statistical difference in shoulder flexion (P < 0.003) and patient's evaluation of treatment effect (P < 0.001). The time and group interactions comparison revealed significant statistical differences in pain score (P < 0.024), external rotation (P < 0.044) and patient's evaluation of treatment effect (P < 0.001). The above statistics were in favour of the corticosteroid and combined groups rather than physiotherapy group. The percentage of recurrence was 36.1, 7.5 and 17.1 in the corticosteroid, physiotherapy and combined groups, respectively (P < 0.001). CONCLUSION: Corticosteroid subdeltoid injection, or combined with physiotherapy, was superior to physiotherapy alone, but the recurrence rate was least in the physiotherapy group.

Reliability and validity of the Shoulder Pain and Disability Index in a sample of patients with frozen shoulder.

BACKGROUND: The Shoulder and Pain Disability Index (SPADI) is a widely used outcome measure. The aim of this study is to explore the reliability and validity of SPADI in a sample of patients with idiopathic frozen shoulder. METHODS: The SPADI was administered to 124 patients with idiopathic frozen shoulder. A sub-group of 29 patients were retested after 7 days. SPADI scores were correlated with other outcome measures (i.e., Disabilities of the Arm, Shoulder and Hand Questionnaire - DASH; Numerical Pain Rating Scale-NPRS; and 36-item Short Form Health Survey-SF-36) to examine construct validity. Structural validity was assessed by a Two-Factors Confirmatory Factor Analysis (CFA). Internal consistency, test-retest reliability, and measurement error were also analyzed. RESULTS: The construct validity was satisfactory as seven out of eight of the expected correlations formulated (≥ 75%) for the subscales were satisfied. The CFA showed good values of all indicators for both Pain and Disability subscales (Comparative Fit Index = 0.999; Tucker-Lewis Index = 0.997; Root Mean Square Error of Approximation = 0.030). Internal consistency was good for pain (α = 0.859) and disability (α = 0.895) subscales. High test-retest reliability (Intraclass correlation coefficient [ICC]) was found for pain (ICC = 0.989 [95% Confidence Interval (CI = 0.975-0.995]) and disability (ICC = 0.990 [95% CI = 0.988-0.998]). Standard Error of Measurement values of 2.27 and 2.32 and Minimal Detectable Change values of 6.27 and 6.25 were calculated for pain and disability subscales, respectively. CONCLUSION: The SPADI demonstrated satisfactory reliability and validity properties in a sample of patients with idiopathic frozen shoulder.

Frozen Shoulder: Diagnosis and Management.

ABSTRACT: Frozen shoulder is a common condition that causes pain and restriction of movement of the shoulder unrelated to secondary causes. It has three classic phases (freezing, frozen, and thawing), and is resolved in most cases within 1 to 2 years. Diagnosis is clinical based on global motion restriction and pain. Imaging plays an ancillary role to narrow the differential diagnosis. Physical therapy, nonsteroidal anti-inflammatories, and injection therapies are standard treatments, although none have been shown to alter the long-term course of the condition. Ultrasound guidance is recommended for injection-based therapy, although not required. Further study should focus on long-term outcomes and treatments that significantly alter the natural course of the disease.

Ultrasound-Guided Infiltrative Treatment Associated with Early Rehabilitation in Adhesive Capsulitis Developed in Post-COVID-19 Syndrome.

Background and Objectives: Post-COVID-19 syndrome is commonly used to describe signs and symptoms that continue or develop after acute COVID-19 for more than 12 weeks. The study aimed to evaluate a treatment strategy in patients with adhesive capsulitis (phase 1) developed in post-COVID-19 syndrome. Materials and Methods: The method used was an interventional pilot study in which 16 vaccinated patients presenting with the clinical and ultrasound features of adhesive capsulitis (phase 1) developed during post-COVID-19 syndrome were treated with infiltrative hydrodistension therapy under ultrasound guidance associated with early rehabilitation treatment. Results: Sixteen patients with post-COVID-19 syndrome treated with ultrasound-guided infiltration and early rehabilitation treatment showed an important improvement in active joint ROM after 10 weeks, especially in shoulder elevation and abduction movements. The VAS mean score before the treatment was 6.9 ± 1.66. After 10 weeks of treatment, the VAS score was 1 ± 0.63. Conclusions: The study demonstrated that the management of adhesive capsulitis (phase 1) developed in post-COVID-19 syndrome, as conducted by physiotherapists in a primary care setting using hydrodistension and a rehabilitation protocol, represented an effective treatment strategy.

Shoulder Injury Related to Vaccine Administration (SIRVA) in 16 Patients Following COVID-19 Vaccination Who Presented to Chiropractic, Orthopedic, and Physiotherapy Clinics in Hong Kong During 2021.

BACKGROUND Shoulder injury related to vaccine administration (SIRVA) occurs when an intramuscular deltoid injection is administered into the shoulder joint. This observational study describes clinical features in 16 patients with SIRVA following Coronavirus 2019 (COVID-19) vaccination who presented to chiropractic, orthopedic, and physiotherapy clinics in Hong Kong between January 1, 2021, and January 1, 2022. MATERIAL AND METHODS Adults age ≥18 with new-onset shoulder pain and imaging-confirmed shoulder pathology were retrospectively identified from 35 clinics. Patient demographics and clinical and vaccination details were extracted from the electronic medical record. Shoulder injury was determined by correlating clinical and imaging features. RESULTS Of 730 patients with shoulder pain, 16 SIRVA cases (mean age, 49±10 years, 75% female) were identified; (12/16, 75%) of patients received the Pfizer-BioNTech vaccine while (4/16, 25%) received Sinovac-CoronaVac. The most common diagnosis was adhesive capsulitis (10/16, 63%), followed by bursitis (3/16, 19%) and supraspinatus tear (3/16, 19%). Mean symptom onset was 3.5±2.5 days post-vaccination, and always occurred after the 2nd or 3rd vaccination, involving reduced shoulder range of motion (ROM). Mean baseline pain was 8.1±1 (out of 10). All patients received conservative care (eg, exercise, manual therapies). At 3-month follow-up, mean pain reduced to 2.4±1.4; all patients had normal shoulder ROM. CONCLUSIONS In the past 2 years, millions of intramuscular COVID-19 vaccinations have been administered. It is important that clinicians are aware of SIRVA as a cause of new symptoms of shoulder injury and should ask the patient about recent vaccinations, including for COVID-19.

Factors related to initial treatment for adhesive capsulitis in the medicare population.

BACKGROUND: Primary adhesive capsulitis (AC) is not well understood, and controversy remains about the most effective treatment approaches. Even less is known about the treatment of AC in the Medicare population. We aimed to fully characterize initial treatment for AC in terms of initial treatment utilization, timing of initial treatments and treatment combinations. METHODS: Using United States Medicare claims from 2010-2012, we explored treatment utilization and patient characteristics associated with initial treatment for primary AC among 7,181 Medicare beneficiaries. Patients with primary AC were identified as patients seeking care for a new shoulder complaint in 2011, with the first visit related to shoulder referred to as the index date, an x-ray or MRI of the shoulder region, and two separate diagnoses of AC (ICD-9-CM codes: 726.00). The treatment period was defined as the 90 days immediately following the index shoulder visit. A multivariable logistic model was used to assess baseline patient factors associated with receiving surgery within the treatment period. RESULTS: Ninety percent of beneficiaries with primary AC received treatment within 90 days of their index shoulder visit. Physical therapy (PT) alone (41%) and injection combined with PT (34%) were the most common treatment approaches. Similar patient profiles emerged across treatment groups, with higher proportions of racial minorities, socioeconomically disadvantaged and more frail patients favoring injections or watchful waiting. Black beneficiaries (OR = 0.37, [0.16, 0.86]) and those residing in the northeast (OR = 0.36, [0.18, 0.69]) had significantly lower odds of receiving surgery in the treatment period. Conversely, younger beneficiaries aged 66-69 years (OR = 6.75, [2.12, 21.52]) and 70-75 years (OR = 5.37, [1.67, 17.17]) and beneficiaries with type 2 diabetes had significantly higher odds of receiving surgery (OR = 1.41, [1.03, 1.92]). CONCLUSIONS: Factors such as patient baseline health and socioeconomic characteristics appear to be important for physicians and Medicare beneficiaries making treatment decisions for primary AC.

What Do We Know About Shoulder Injury Related to Vaccine Administration? An Updated Systematic Review.

BACKGROUND: Shoulder injury related to vaccine administration (SIRVA) is postulated to be an immune-mediated inflammatory response to a vaccine antigen injected into or near the subacromial bursae or synovium, leading to shoulder pain and dysfunction. The number of studies on this topic is rapidly increasing. Recent comparative studies have reported conflicting conclusions, which suggests that a systematic review of the best-available evidence may be helpful. QUESTIONS/PURPOSES: In this systematic review, we asked: What are the (1) clinical characteristics, (2) diagnoses, and (3) management approaches and outcomes reported in association with SIRVA? METHODS: A search was performed on October 4, 2021, of the PubMed and Medline databases for studies related to SIRVA. Inclusion criteria were English-language comparative studies, case series, and case reports that involved shoulder pain occurring after vaccination. Studies of exclusively neurologic conditions after vaccination were excluded. Forty-two studies met the eligibility criteria, including three retrospective comparative studies (72 patients and 105 controls), five database case series (2273 patients), and 34 case reports (49 patients). Study quality was assessed for the database case series and retrospective comparative studies using the Methodological Index for Non-randomized Studies tool. RESULTS: Among patients in the case reports, the median age was 51 years (range 15-90 years), and 73% (36 of 49) were women. BMI was reported for 24% of patients (12 of 49) in case reports, with a median of 23.5 kg/m2 (range 21-37.2 kg/m2). The most common symptoms were shoulder pain and reduced ROM. The most common diagnoses were shoulder bursitis, adhesive capsulitis, and rotator cuff tears. The most frequent management modalities included physical or occupational therapy, NSAIDs, and steroid injections, followed by surgery, which was generally used for patients whose symptoms persisted despite nonsurgical management. Full resolution of symptoms was reported in 2.9% to 56% of patients. CONCLUSION: The association between inflammatory conditions of the shoulder (such as bursitis) and vaccination appears to be exceedingly rare, occurring after approximately 1:130,000 vaccination events according to the best-available comparative study. Currently, there is no confirmatory experimental evidence supporting the theory of an immune-mediated inflammatory response to vaccine antigens. Although the clinical evidence is limited, similar to any bursitis, typical treatments appear effective, and surgery should rarely be performed. Additional research is needed to determine the best injection technique or evaluate alternate injection sites such as the anterolateral thigh that do not involve positioning a needle close to the shoulder.

Urdu translation of Shoulder Pain and Disability Index (SPADI) and its validity and reliability on adhesive capsulitis patients.

BACKGROUND: Excessive scar tissues around the shoulder are the results of shoulder pathologies that lead to pain and disability. The Shoulder pain and disability index (SPADI) is used to measure the level of pain and disability in patients with shoulder pathology. SPADI is translated into Urdu and its validity and reliability are measured on patients with adhesive capsulitis. OBJECTIVE: The study was aimed to translate the SPADI in Urdu and to evaluate its reliability and validity in patients with shoulder adhesive capsulitis. METHODS: Translation of SPADI in Urdu was conducted by applying the standardized process. Two forward translations in Urdu were made T1 and T2 by bilingual translators. Urdu version of SPADI was drafted after experts' opinion. Two Backward English translations of Urdu SPADI were made BT1 and BT2 and the back translation was finalized by the consensus of all experts. After this process of reviewing by the professional experts, 3rd version of Urdu SPADI was drafted. The Final version was drafted after its application on 10 patients. Its reliability and validity were tested on 150 patients with shoulder adhesive capsulitis. RESULTS: Content Validity Index was good with values of each item > 0.85. For Test-retest reliability, the Intraclass correlation coefficient (ICC2,1) was measured with a value of 0.89 which showed good Test-retest reliability. The internal consistency and reliability of SPADI were calculated by Cronbach's alpha for a total score with a value of 0.94. Construct validity and Concurrent validity were determined. In Construct validity, factor analysis of Urdu SPADI showed two factors and a cumulative variance of 75.443%. CONCLUSION: It was concluded that the Urdu version of SPADI is a valuable translation that is a valid assessment tool for patients with shoulder adhesive capsulitis. It has good validity and test-retest reliability.

Clinical characteristics and management of olecranon and prepatellar septic bursitis in a multicentre study.

BACKGROUND: No current guidelines are available for managing septic bursitis (SB). OBJECTIVES: To describe the clinical characteristics and management of olecranon and prepatellar SB in five French tertiary care centres. METHODS: This is a retrospective observational multicentre study. SB was diagnosed on the basis of positive cultures of bursal aspirate. In the absence of positive bursal fluid, the diagnosis came from typical clinical presentation, exclusion of other causes of bursitis and favourable response to antibiotic therapy. RESULTS: We included 272 patients (median age of 53 years, 85.3% male and 22.8% with at least one comorbidity). A microorganism was identified in 184 patients (67.6%), from bursal fluids in all but 4. We identified staphylococci in 135 samples (73.4%), streptococci in 35 (19%) and 10 (5.5%) were polymicrobial, while 43/223 bursal samples remained sterile (19.3%). Forty-nine patients (18%) were managed without bursal fluid analysis. Antibiotic treatment was initially administered IV in 41% and this route was preferred in case of fever (P = 0.003) or extensive cellulitis (P = 0.002). Seventy-one (26%) patients were treated surgically. A low failure rate was observed (n = 16/272, 5.9%) and failures were more frequent when the antibiotic therapy lasted <14 days (P = 0.02) in both surgically and medically treated patients. CONCLUSIONS: Despite variable treatments, SB resolved in the majority of cases even when the treatment was exclusively medical. The success rate was equivalent in the non-surgical and the surgical management groups. However, a treatment duration of <14 days may require special attention in both groups.

The epidemiology and etiology of adhesive capsulitis in the U.S. Medicare population.

BACKGROUND: Adhesive capsulitis (AC) of the shoulder, also known as frozen shoulder, causes substantial pain and disability. In cases of secondary AC, the inflammation and fibrosis of the synovial joint can be triggered by trauma or surgery to the joint followed by extended immobility. However, for primary AC the inciting trigger is unknown. The burden of the disorder among the elderly is also unknown leading to this age group being left out of therapeutic research studies, potentially receiving delayed diagnoses, and unknown financial costs to the Medicare system. The purpose of this analysis was to describe the epidemiology of AC in individuals over the age of 65, an age group little studied for this disorder. The second purpose was to investigate whether specific medications, co-morbidities, infections, and traumas are risk factors or triggers for primary AC in this population. METHODS: We used Medicare claims data from 2010-2012 to investigate the prevalence of AC and assess comorbid risk factors and seasonality. Selected medications, distal trauma, and classes of infections as potential inflammatory triggers for primary AC were investigated using a case-control study design with patients with rotator cuff tears as the comparison group. Medications were identified from National Drug codes and translated to World Health Organization ATC codes for analysis. Health conditions were identified using ICD9-CM codes. RESULTS: We found a one-year prevalence rate of AC of approximately 0.35% among adults aged 65 years and older which translates to approximately 142,000 older adults in the United States having frozen shoulder syndrome. Diabetes and Parkinson's disease were significantly associated with the diagnosis of AC in the elderly. Cases were somewhat more common from August through December, although a clear seasonal trend was not observed. Medications, traumas, and infections were similar for cases and controls. CONCLUSIONS: This investigation identified the burden of AC in the US elderly population and applied case-control methodology to identify triggers for its onset in this population. Efforts to reduce chronic health conditions such as diabetes may reduce seemingly unrelated conditions such as AC. The inciting trigger for this idiopathic condition remains elusive.

Effectiveness of interactive augmented reality-based telerehabilitation in patients with adhesive capsulitis: protocol for a multi-center randomized controlled trial.

BACKGROUND: As the primary treatment for adhesive capsulitis, intensive and accurate home exercise is as important as physical therapy in hospitals. Augmented reality (AR)-based telerehabilitation has been implemented recently in various musculoskeletal conditions to increase patient compliance and enable patients to exercise with the correct posture. The objective of this study is to present a protocol for investigating the additive effect of interactive AR-based telerehabilitation in comparison with the usual care for patients with adhesive capsulitis. METHODS: This study presents the protocol of a prospective, multi-center, single-blinded, two-armed randomized controlled trial (RCT). One hundred patients with stage I or II adhesive capsulitis will be recruited at the physical medicine and rehabilitation clinic. Patients will be randomly divided into two groups with 1:1 allocation. The intervention group will receive 3 months of hospital-based physical therapy in conjunction with home-based telerehabilitation. The control group will receive 3 months of hospital-based physical therapy in conjunction with a home-based exercise described in a brochure provided by the hospital. The primary outcome will be the change in passive range of motion (ROM) of the affected shoulder joint from baseline to 12 weeks after baseline assessment. The secondary outcomes will be active ROM, pain measured with the numeric rating scale, shoulder pain and disability index, 36-Item Short Form Survey, EuroQoL-5D-5L, and Canadian Occupational Performance Measure. DISCUSSION: This will be the first RCT study protocol to investigate the effect of telerehabilitation in patients with adhesive capsulitis. The result of this RCT will determine whether AR-based telerehabilitation is more effective than a brochure-based home exercise program and will provide evidence of the usefulness of "telerehabilitation" using hardware (IoT) and software (monitoring platform) technologies to develop "digital therapeutics" for the future. TRIAL REGISTRATION: This trial was retrospectively registered at the Clinicaltrials.gov website on 20 March 2020, with the identifier NCT04316130 .

Efficacy of high-intensity laser therapy in patients with adhesive capsulitis: a sham-controlled randomized controlled trial.

Adhesive capsulitis is an idiopathic condition characterized by painful shoulder stiffness, impairs quality of life, and causes disability. The purpose of the study is to evaluate the effects of high-intensity laser therapy (HILT) on pain, disability, and quality of life in patients with adhesive capsulitis. The study was designed as a prospective, double-blinded, and sham-controlled randomized trial. Thirty-six patients diagnosed with adhesive capsulitis were randomized into HILT plus therapeutic exercises, sham-laser plus therapeutic exercises, and control-therapeutic exercises only groups. All groups received 25 min of exercises to the shoulder joint supervised by a physiotherapist. Patients in both the HILT and the sham-laser group were blinded to their group randomization. The interventions were performed five times a week for 3 weeks (a total of 15 sessions). The primary outcome measure was the visual analogue scale for pain (Visual Analog Scale for pain (VAS)-pain). The secondary outcome measures were shoulder pain and disability index (SPADI), short-form health survey-36 (SF-36), and range of motion (ROM) of the shoulder joint. Assessments were performed at pre-intervention, post-intervention, and 12-week follow-up by an investigator who was blinded. Thirty-one participants completed the study. HILT plus therapeutic exercises showed significant differences in VAS-pain, SPADI-pain, and SF-36 (subgroups of energy/fatigue, pain, and general health) scores (all P < 0.05). All groups provided comparable improvements in SPADI-disability and ROM of shoulder joint after the interventions and during the follow-up (all P < 0.05). Fifteen sessions of HILT are superior to improve pain and quality of life but not superior in terms of disability or function in patients with adhesive capsulitis. Clinical trial registration number: The study was registered at the US National Institutes of Health ( ClinicalTrials.gov ) (NCT03929276) and available at https://clinicaltrials.gov/ct2/show/NCT03929276?term=tu%C4%9Fba+atan&draw=2&rank=3.

Correlation of Patient Reported Outcome Measurement Information System (PROMIS) with American Shoulder and Elbow Surgeon (ASES), and Constant (CS) scores in idiopathic adhesive capsulitis.

PURPOSE: To correlate the Patient Reported Outcomes Measurement Information System Upper Extremity (PROMIS UE) score with pre-existing validated outcome scores, American Shoulder and Elbow Surgeons score (ASES), and Constant score (CS) in patients with idiopathic adhesive capsulitis (AC). METHODS: Patients with a clinical diagnosis of idiopathic AC ("freezing" or "frozen" phases) who agreed to complete the ASES, CS, and PROMIS UE scores during their office visit were included in this study. Trained researchers performed the objective clinical assessments on the included patients. Responses to the 3 outcome scores were statistically analyzed and compared using Pearson correlation coefficients. Floor and ceiling effects were calculated. RESULTS: The final cohort included 100 patients with AC, of whom there were 72% female and 87% right hand dominant, with a mean age of 55 years. The PROMIS UE required fewer question responses (5.02 ± 1.84) compared with the fixed question burden with ASES (12) and CS (9). The mean outcome scores were 34.6 ± 2.5 (PROMIS UE), 55 ± 22 (ASES), and 51 ± 16 (CS). The PROMIS UE displayed an excellent correlation with both the ASES (r = 0.80, 95% confidence interval [0.72, 0.86], P < .001) and CS (r = 0.76, 95% confidence interval [0.67, 0.83], P < .001). Neither ceiling nor floor effects were present. CONCLUSION: The PROMIS UE displayed comparable efficacy to commonly used legacy outcome scores (ASES and CS) in AC. A lower question burden with the PROMIS UE carries potential for wider acceptability with the researchers and patients with shoulder pathology.

[Gigantic prepatellar "tumor" in rheumatoid arthritis-a case report]. / Gigantischer präpatellarer "Tumor" bei rheumatoider Arthritis ­ ein Case Report.

In soft tissue tumors of the extremities it is of utmost importance to differentiate between benign and malignant entities. The majority of the swellings vary from benign tissue changes through soft tissue sarcomas up to pseudotumors. Because of the low incidence of malignancy and the predominantly benign alterations together with a high heterogeneity, there is a need for a reproducible diagnostic and therapeutic concept for the treatment of all tumors of the extremities. This article reports the case of a 59-year-old patient with longstanding rheumatoid arthritis who presented to the orthopedic rheumatologic consultation with a massive swelling directly ventral to the knee joint. At that point the tumor had already grown very slowly for 5 years. The staged diagnostic process (patient history, clinical, laboratory tests, sonographic examinations, X­ray, MRI with contrast medium) revealed no trace of malignancy whatsoever. The treatment then consisted of the complete surgical excision in accordance with the recommendations for tumor surgery. Histopathological findings confirmed the diagnosis of a massive prepatellar bursitis. Initially, the extreme and solid prepatellar swelling was suspected of being malignant; however, this could already be broadly excluded preoperatively. This article presents the rationale and the orthopedic rheumatologic approach for addressing unclear space-occupying lesions of the musculoskeletal system in patients with rheumatism. In the inflammatory systemic disease in the differential diagnosis periarticular swellings can ultimately also have benign causes, such as an organized bursitis.

Machine learning algorithms trained with pre-hospital acquired history-taking data can accurately differentiate diagnoses in patients with hip complaints.

Background and purpose - Machine learning (ML) techniques are a form of artificial intelligence able to analyze big data. Analyzing the outcome of (digital) questionnaires, ML might recognize different patterns in answers that might relate to different types of pathology. With this study, we investigated the proof-of-principle of ML-based diagnosis in patients with hip complaints using a digital questionnaire and the Kellgren and Lawrence (KL) osteoarthritis score.Patients and methods - 548 patients (> 55 years old) scheduled for consultation of hip complaints were asked to participate in this study and fill in an online questionnaire. Our questionnaire consists of 27 questions related to general history-taking and validated patient-related outcome measures (Oxford Hip Score and a Numeric Rating Scale for pain). 336 fully completed questionnaires were related to their classified diagnosis (either hip osteoarthritis, bursitis or tendinitis, or other pathology). Different AI techniques were used to relate questionnaire outcome and hip diagnoses. Resulting area under the curve (AUC) and classification accuracy (CA) are reported to identify the best scoring AI model. The accuracy of different ML models was compared using questionnaire outcome with and without radiologic KL scores for degree of osteoarthritis.Results - The most accurate ML model for diagnosis of patients with hip complaints was the Random Forest model (AUC 82%, 95% CI 0.78-0.86; CA 69%, CI 0.64-0.74) and most accurate analysis with addition of KL scores was with a Support Vector Machine model (AUC 89%, CI 0.86-0.92; CA 83%, CI 0.79-0.87).Interpretation - Analysis of self-reported online questionnaires related to hip complaints can differentiate between basic hip pathologies. The addition of radiological scores for osteoarthritis further improves these outcomes.

Adhesive capsulitis: A review for clinicians.

ABSTRACT: Adhesive capsulitis, a common primary care and orthopedic diagnosis often referred to as frozen shoulder, is a painful inflammatory process that leads to a mechanical block in active and passive range of shoulder motion. Risk factors include diabetes and thyroid dysfunction. Diagnosis is made based on physical examination, but can be augmented by diagnostic imaging. Nonsurgical management is the mainstay of treatment because the disease is self-limiting. However, some patients may need surgical intervention.
