Relato de caso de lombalgia inflamatória com extenso comprometimento anatômico-funcional: a importância de uma adequada abordagem da dor lombar na Atenção Primária à Saúde / Case report of inflammatory low back pain with extensive anatomical-functional impairment: The importance of an adequate approach to low back pain in Primary Care / Presentación de un caso de lumbalgia inflamatoria con afectación anatómico-funcional extensa: La importancia de un abordaje adecuado de la lumbalgia en Atención Primaria de Salud

Introdução: A lombalgia é uma condição prevalente e que apresenta importante impacto na capacidade funcional e na qualidade de vida, sendo a sua correta abordagem na Atenção Primária à Saúde fundamental para a identificação e o estabelecimento de um diagnóstico etiológico precoce de possíveis patologias que possam estar relacionadas a desfechos mórbidos e a graves limitações funcionais. Apresentação do caso: Paciente de 56 anos, sexo masculino, hipertenso, foi encaminhado para serviço especializado de reumatologia com histórico de lombalgia havia mais de 20 anos. Ao exame físico foi constatada presença de deformidades da coluna vertebral e extensa limitação de movimentos. Exames radiográficos mostravam esclerose de articulações sacroilíacas, osteopenia difusa e coluna vertebral em aspecto de "bambu". Conclusões: Constata-se a importância de que na abordagem das lombalgias na atenção primária se busque o reconhecimento de possíveis etiologias graves e potencialmente incapacitantes que possam estar subjacentes à queixa de dor lombar. Com esse objetivo, é fundamental o reconhecimento das chamadas red flags relacionadas às lombalgias, além de sua caracterização como mecânica ou inflamatória. Perante a atuação da atenção primária no oferecimento de um cuidado pautado na integralidade e na prevenção de agravos, reafirma-se a importância de uma avaliação clínica pormenorizada das lombalgias nesse nível de atenção à saúde.

Introduction: Low back pain is a prevalent condition that has an important impact on functional capacity and quality of life, and its correct approach in Primary Care is fundamental to the identification and establishment of an early etiological diagnosis of possible pathologies that may be related to outcomes morbid conditions and serious functional limitations. Case presentation: 56-year-old male patient, hypertensive, referred to a specialized rheumatology service with a history of low back pain for over 20 years. Physical examination revealed the presence of spinal deformities and extensive movement limitations. Radiographic examinations showing sclerosis of the sacro-iliac joints, diffuse osteopenia and a "bamboo" appearance of the spine. Conclusions: It is important that in the approach of low back pain in Primary Care, we seek to recognize possible serious and potentially disabling etiologies that may underlie the complaint of low back pain. For that, it is essential to recognize the so-called "red flags" related to low back pain, in addition to its characterization as mechanical or inflammatory. Given the role of Primary Care in offering care based on integrality and in the prevention of injuries, the importance of a detailed clinical assessment of low back pain at this level of health care is reaffirmed.

Programa de gimnasia laboral para los moldeadores manuales metalúrgicos

Los trastornos músculo-esqueléticos relacionados con el trabajo constituyen motivo de preocupación para la comunidad científica, avalado por su efecto negativo en la vida de los trabajadores y la productividad de las empresas. En el proceso de fundición de metales, los moldeadores manuales con pisón neumático exteriorizan manifestaciones de estas afecciones. Ello indujo a realizar una investigación que tuvo como objetivo elaborar un programa de Gimnasia Laboral para contribuir a la atención de los trastornos músculo-esqueléticos en los moldeadores manuales metalúrgicos. Para recopilar, analizar y procesar los datos se emplearon métodos teóricos, empíricos y matemático-estadísticos, entre ellos el histórico-lógico, analítico-sintético, inductivo-deductivo, sistémico-estructural-funcional, la observación participante, encuesta, entrevista, revisión documental, el experimento, criterio de usuarios y la estadística descriptiva e inferencial. La población objeto de estudio estuvo conformada por 19 moldeadores manuales metalúrgicos, seleccionados de forma intencional. El diagnóstico y la sistematización teórica alcanzada posibilitaron elaborar un programa de Gimnasia Laboral, en correspondencia con los requerimientos del proceso de moldeo, cuya efectividad fue constatada.

As lesões músculo-esqueléticas relacionadas com o trabalho são motivo de preocupação para a comunidade científica, sustentadas pelos seus efeitos negativos na vida dos trabalhadores e na produtividade das empresas. No processo de fundição do metal, os moldadores manuais com compactador pneumático externalizam as manifestações dessas condições. Isso originou uma pesquisa que teve como objetivo desenvolver um programa de Ginástica Laboral para contribuir no cuidado de lesões osteomusculares em moldadores manuais metalúrgicos. Para coletar, analisar e tratar os dados foram utilizados métodos teóricos, empíricos e matemático-estatísticos, incluindo histórico-lógico, analítico-sintético, indutivo-dedutivo, sistêmico-estrutural-funcional, observação participante, levantamento, entrevista, revisão documental, o experimento, critérios de usuário e estatísticas descritivas e inferenciais. A população em estudo foi composta por 19 modeladores manuais metalúrgicos, selecionados intencionalmente. O diagnóstico e a sistematização teórica conseguidos permitiram desenvolver um programa de Ginástica Laboral, em correspondência com as exigências do processo de moldagem, cuja eficácia foi verificada.

Work-related musculoskeletal disorders are a cause of concern for the scientific community, supported by their negative effect on the lives of workers and the productivity of companies. In the metal casting process, manual molders with pneumatic tamper externalize manifestations of these conditions. This led to carrying out a research that aimed to develop a Labor Gymnastics program to contribute to the care of musculoskeletal disorders in metallurgical manual shapers. To collect, analyze and process the data, theoretical, empirical and mathematical-statistical methods were used, including historical-logical, analytical-synthetic, inductive-deductive, systemic-structural-functional, participant observation, survey, interview, documentary review, the experiment, user criteria and descriptive and inferential statistics. The population under study was made up of 19 metallurgical manual shapers, intentionally selected. The diagnosis and theoretical systematization achieved made it possible to develop a Labor Gymnastics program, in correspondence with the requirements of the molding process, whose effectiveness was verified.

Examining the Building Blocks of Health Behavior Change in Rheumatology Rehabilitation: A Theory-Driven Qualitative Study.

Purpose: To identify and describe behavior change techniques (BCTs) used in rehabilitation for patients with rheumatic and musculoskeletal diseases (RMDs), according to their own perceptions. Further, to examine patients' descriptions of their capability, opportunity, motivation, and readiness for health behavior change. Patients and Methods: Patients were adults in need of specialized, multidisciplinary rehabilitation services due to inflammatory rheumatic disease, systemic connective tissue disease, or fibromyalgia / chronic widespread pain. Semi-structured interviews of 21 patients were analyzed with deductive qualitative content analysis applying three theoretical frameworks: the Behavior Change Technique Taxonomy, the transtheoretical model and stages of change, and the capability, opportunity, and motivation model of behavior. Results: Forty-six BCTs aggregated within 14 BCT groups were identified used by either patients, healthcare professionals (HPs), or both. Goals and planning, feedback and monitoring, social support, shaping knowledge, repetition and substitution were most frequently used to facilitate behavior change. Twenty patients had reached the action stage and made specific lifestyle changes concerning more than half of their goals. Concerning other goals, 6 of these patients reported to be contemplating behavior change and 15 to be preparing for it. The rehabilitation process appeared to strengthen capability, opportunity, motivation, and the desired behaviors. Patient-reported barriers to behavior change were connected with restrictions in physical capability resulting from an unpredictable and fluctuating disease course, weakened motivation, and contextual factors, such as lack of access to healthcare support and training facilities, and high domestic care burden. Conclusion: The rehabilitation process seemed to strengthen individual and contextual prerequisites for behavior change and facilitate the use of required techniques and engagement in the desired behaviors. However, patients with RMDs may need prolonged support from HPs to integrate healthy lifestyle changes into everyday life. The findings can be used to optimize rehabilitation interventions and patients' persistent engagement in healthy behaviors.

Work-Related Fear-Avoidance Beliefs and Risk of Low-Back Pain: Prospective Cohort Study Among Healthcare Workers.

PURPOSE: Low-back pain (LBP) is a prevalent condition among healthcare workers, negatively affecting well-being and work ability. Research has identified fear-avoidance beliefs, i.e., the belief that physical activities worsen or prolong pain, as a key psychological factor in LBP. Given the physical demands of healthcare work, understanding the link between fear-avoidance and LBP is crucial for effective prevention and management strategies. This study investigated the prospective association between fear-avoidance beliefs and risk of increased LBP intensity and duration in hospital workers. METHODS: Fear-avoidance beliefs and LBP were assessed in 1933 healthcare workers from 389 departments at 19 hospitals at baseline and 1-year follow-up. Associations between baseline work-related fear-avoidance beliefs (FABW) and LBP intensity and duration at follow-up were analyzed using cumulative logistic regression, adjusting for various factors including age, sex, baseline LBP, education, seniority, patient transfers, psychosocial work environment, and lifestyle. RESULTS: Moderate and high FABW was associated with higher odds of increased pain intensity (OR: 1.37 [95% CI 1.09-1.73] and 1.85 [95% CI 1.18-2.88], respectively) and prolonged pain duration (OR: 1.37 [95% CI 1.05-1.78] and 2.27 [95% CI 1.50-3.44], respectively). A sensitivity analysis including only female nurses showed similar results, with the high FABW group having significantly higher odds of increased pain intensity (OR 2.95, 95% CI 1.84-4.72) and duration (OR 2.64, 95% CI 1.55-4.49). CONCLUSIONS: Fear-avoidance beliefs increase the risk of LBP intensity and duration among healthcare workers, emphasizing the need for interventions dealing with psychological aspects of LBP.

Female teleworkers with pain have the highest presenteeism, where its primary contributing variable was not those of musculoskeletal disability.

Presenteeism, among desk workers with pain can be affected by musculoskeletal disabilities (MSDs), working styles, and gender. In this study, teleworkers were defined as those who teleworked >70% of the time at home, while others were defined as non-full teleworkers. This study aimed to (1) compare the magnitude of presenteeism among four groups: male and female teleworkers with pain and male and female non-full teleworkers with pain, and (2) create a regression model of presenteeism with 66 independent biopsychosocial variables for each group. Data were collected through an anonymous online survey. Presenteeism was evaluated using the work functioning impairment scale. The 66 independent biopsychosocial variables included four disability measures, namely, stiff neck/shoulders, low back pain, and upper or lower limb problems, along with other factors relevant to presenteeism in previous studies, such as age, body mass index, comorbidities, work-related variables, pain catastrophizing, and various psychological distress measures. Data from 1068 male non-full teleworkers, 1,043 female non-full teleworkers, 282 male teleworkers, and 307 female teleworkers were analyzed. Presenteeism was the highest among female teleworkers with pain. Furthermore, in all models, overall psychological distress, rather than the four MSD measures, was the primary contributing factor for presenteeism.

Risk factors for adverse drug reactions to sulfamethoxazole-trimethoprim prophylaxis in patients with rheumatic and musculoskeletal diseases.

OBJECTIVES: Risk factors for adverse drug reactions (ADRs) associated with prophylactic sulfamethoxazole-trimethoprim (SMX/TMP) in patients with rheumatic and musculoskeletal diseases undergoing immunosuppressive therapy remain unclear, we aimed to identify the risk factors associated with ADRs. METHODS: Consecutive patients with rheumatic and musculoskeletal diseases, who were admitted to Keio University Hospital and received prophylactic administration of SMX/TMP, were included. Data regarding ADRs to SMX/TMP were collected to identify associated risk factors using multivariable analysis. RESULTS: Of 438 patients included in the analysis, 82 (18.7%) experienced ADRs. Patients in the ADRs group were significantly older, had chronic kidney disease, and exhibited lower lymphocyte and platelet counts, lower albumin levels, lower estimated glomerular filtration rates, higher aspartate aminotransferase levels, and higher ferritin levels than those in the non-ADR group. Regarding underlying rheumatic and musculoskeletal diseases, adult-onset Still's disease (ASD) was associated with a significantly higher incidence of ADRs (67%) than other diseases. Multivariable analysis identified the presence of ASD and low lymphocyte counts as independent risk factors for allergic ADRs, and older age and use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers for non-allergic ADRs. CONCLUSIONS: Risk factors for ADRs associated with prophylactic SMX/TMP treatment in patients with rheumatic and musculoskeletal diseases were identified.

OpenSim Moco tracking simulations efficiently replicate predictive simulation results across morphologically diverse shoulder models.

OpenSim Moco enables solving for an optimal motion using Predictive and Tracking simulations. However, Predictive simulations are computationally prohibitive, and the efficacy of Tracking in deviating from its reference is unclear. This study compares Tracking and Predictive approaches applied to the generation of morphology-specific motion in statistically-derived musculoskeletal shoulder models. The signal analysis software, CORA, determined mean correlation ratings between Tracking and Predictive solutions of 0.91 ± 0.06 and 0.91 ± 0.07 for lateral and forward-reaching tasks. Additionally, Tracking provided computational speed-up of 6-8 times. Therefore, Tracking is an efficient approach that yields results equivalent to Predictive, facilitating future large-scale modelling studies.

Diffusion tensor imaging shows increased physis organization after growth hormone initiation in hypophosphatasia.

Hypophosphatasia is a rare heritable disorder of bone mineralization, with a spectrum of severity based on age of initial presentation. We describe the case of a 14-year-old boy with gene-confirmed inherited hypophosphatasia and growth hormone deficiency, who presented with short stature, unremarkable radiographs, and only minor physeal and metaphyseal changes on magnetic resonance (MR) imaging. Diffusion tensor imaging (DTI) before growth hormone initiation revealed abundant, non-parallel tracts in the physes and metaphyses with loss of the typical columnar organization. After 8 months of growth hormone treatment, DTI scans revealed realigned, nearly parallel, longer physeal tracts; duplication of tract volume; and decreased and more typical fractional anisotropy values. DTI can thus visualize physeal tract changes over time, could be a more sensitive diagnostic technique in milder physeal abnormality cases, and may be a potential marker of growth hormone treatment response.

Effectiveness of a physiotherapy self-management programme for adult patients with chronic non-specific low back pain in low- and middle-income countries: protocol for a systematic review and meta-analysis.

INTRODUCTION: Chronic non-specific low back pain (CNLBP) is among the most common musculoskeletal system conditions reported worldwide; however, few studies are available from low- and middle-income countries (LMICs). Self-management is a set of tasks performed by the patient aiming at managing their symptoms and interference in activities, mood and relationships due to pain. A physiotherapy-guided self-management programme (SMP) following a biopsychosocial approach has been reported as effective and affordable in the management of CNLBP in high-income countries. The objective of this systematic review is to determine the overall effectiveness of SMPs for adults with CNLBP in LMICs. METHODS AND ANALYSIS: In this systematic review, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Protocol (PRISMA-P) guidelines will be followed. A three-step search strategy will be used to search the electronic databases (PubMed, MEDLINE, SPORTDiscus, Scopus and CINAHL, Academic Search Complete and PEDro) for randomised controlled trials assessing the effectiveness of physiotherapy-guided self-management for CNLBP among adult participants in LMICs. The processes of screening search results for eligible studies, extracting data from included studies and appraising will be done independently by at least two review authors. Random effects meta-analysis will be used to synthesise results and heterogeneity will be assessed using the I2 test statistic and χ2 test. ETHICS AND DISSEMINATION: Ethics clearance was obtained for the broader PhD study on the development of a physiotherapy-guided SMP for adult people with CNLBP in Limpopo Province, South Africa. The results of the manuscript for this protocol will be published in peer-reviewed journals and also presented at conferences, symposia, and congresses. PROSPERO REGISTRATION NUMBER: CRD42023399572.

Achilles tendon compliance influences tendon loading more than Achilles tendon twist in Achilles tendinopathy: a musculoskeletal modeling approach.

The Achilles tendon exhibits anatomical variations in subtendon twist among individuals, and its compliance can change due to conditions like Achilles tendinopathy. However, current musculoskeletal models overlook these material and morphological variations. This study aimed to investigate the impact of altering Achilles subtendon insertion points and compliance on the triceps surae muscle forces, and therefore tendon loading, during dynamic exercises in one Achilles tendinopathy patient. First, subtendon insertion points were altered in the musculoskeletal model based on a subject-specific 3D freehand ultrasound model and for three types of subtendon twists: low, medium, and high. Second, tendon compliance was modeled based on experimental values, creating three musculoskeletal models: compliant, mean, and stiff. Results indicated that tendon compliance had a larger effect than tendon twist on triceps surae muscle forces. Altering subtendon insertion points to the three types of twist showed a maximal change of 2.3% in muscle force contribution compared to the no-twist model. During the eccentric rehabilitation exercise-a common exercise choice during rehabilitation-the compliant tendon model showed substantial differences compared to the generic (control) musculoskeletal model, resulting in decreased gastrocnemius medialis (-3.5%) and gastrocnemius lateralis (-3.2%) contributions and increased soleus contribution (+ 6.6%). Our study results highlight the necessity of incorporating tendon compliance in musculoskeletal models to accurately predict triceps surae muscle forces, especially in individuals with increased tendon compliance, such as patients with Achilles tendinopathy. Such findings contribute to more accurate predictions of muscle forces and hence, personalized rehabilitation strategies.

A Case Report Emphasizing the Advantageous Effect of Mulligan Mobilization Technique in the Management of Rotator Cuff Syndrome to Enhance Functional Recovery in a 65-Year-Old Farmer.

Adults with shoulder pain often have partial rotator cuff injuries (RCIs) as the underlying cause. RC partial tears are one of the common conditions that can have a major influence on a wide range of people, including sportspeople, workers, and sedentary adults with rotator cuff syndrome (RCS). Any injury, disease, or deteriorating condition that affects the shoulder's RC muscles and tendons is recognized as RCS. Subacromial bursitis, RC tendonitis, subacromial impingement syndrome (SIS), rotator cuff tears (RCTs), etc., are a few disorders linked to RCS. For partial RCT, nonoperative treatment options include physical therapy, anti-inflammatories, analgesics, medication, rest or activity adjustments, and corticosteroid injections. We present the case of a 65-year-old male farmer by occupation, suffering from an RCI on the right side. Following a history of trauma to the right shoulder from a collision with a bull on his farm, the patient complained of pain and limitations in his right shoulder joint. The goal of the rehabilitation program was to maximize the patient's recovery through pain management, range-of-motion (ROM) restoration, muscle strength building, and functional activities. To improve muscular strength and preserve the ROM, strengthening exercises and isometrics were all incorporated into the rehabilitation regimen at the same time. The patient's progress was monitored at scheduled times during rehabilitation using the disabilities of arm, shoulder, and hand (DASH) score, visual analog scale (VAS), goniometer for normal ROM, and the upper extremity functional scale (UEFS). In this case study, the care and recovery of a patient with RC tendinopathy who received physical therapy are examined.

Exploring Older Adults' Perceptions of Using Digital Health Platforms for Self-Managing Musculoskeletal Health Conditions: Focus Group Study.

BACKGROUND: Digital technologies can assist and optimize health care processes. This is increasingly the case in the musculoskeletal health domain, where digital platforms can be used to support the self-management of musculoskeletal conditions, as well as access to services. However, given a large proportion of the population with musculoskeletal conditions are older adults (aged ≥60 years), it is important to consider the acceptability of such platforms within this demographic. OBJECTIVE: This study aims to explore participants' opinions and perceptions on the use of digital platforms for supporting the self-management of musculoskeletal conditions within older adult (aged ≥60 years) populations and to gather their opinions on real examples. METHODS: A total of 2 focus groups (focus group 1: 6/15, 40%; focus group 2: 9/15, 60%) were conducted, in which participants answered questions about their thoughts on using digital health platforms to prevent or manage musculoskeletal conditions. Participants were further presented with 2 example scenarios, which were then discussed. Interviews were audio recorded, transcribed, and analyzed thematically. Participants were aged ≥60 years and with or without current musculoskeletal conditions. Prior experience of using smartphone apps or other digital health platforms for musculoskeletal conditions was not required. Focus groups took place virtually using the Teams (Microsoft Corp) platform. RESULTS: A total of 6 themes were identified across both focus groups: "experiences of digital health platforms," "preference for human contact," "barriers to accessing clinical services," "individual differences and digital literacy," "trust in technology," and "features and benefits of digital health technologies." Each theme is discussed in detail based on the interview responses. The findings revealed that most participants had some existing experience with digital health platforms for preventing or managing musculoskeletal conditions. Overall, there was a lack of trust in and low expectations of quality for digital platforms for musculoskeletal health within this age group. While there was some concern about the use of digital platforms in place of in-person health consultations, several benefits were also identified. CONCLUSIONS: Results highlighted the need for better communication on the benefits of using digital platforms to support the self-management of musculoskeletal conditions, without the platforms replacing the role of the health care professionals. The concerns about which apps are of suitable quality and trustworthiness lead us to recommend raising public awareness around the role of organizations that verify and assess the quality of digital health platforms.

Running on empty: Exploring stem cell exhaustion in geriatric musculoskeletal disease.

Ageing populations globally are associated with increased musculoskeletal disease, including osteoporosis and sarcopenia. These conditions place a significant burden of disease on the individual, society and the economy. To address this, we need to understand the underpinning biological changes, including stem cell exhaustion, which plays a key role in the ageing of the musculoskeletal system. This review of the recent evidence provides an overview of the associated biological processes. The review utilised the PubMed/Medline, Science Direct, and Google Scholar databases. Mechanisms of ageing identified involve a reaction to the chronic inflammation and oxidative stress associated with ageing, resulting in progenitor cell senescence and adipogenic differentiation, leading to decreased mass and quality of both bone and muscle tissue. Although the mechanisms underpinning stem cell exhaustion are unclear, it remains a promising avenue through which to identify new strategies for prevention, detection and management.

Prevalence and related factors for neck pain in military personnel: a systematic review.

Purpose: In the military, neck pain is second to low back pain among musculoskeletal disorders. However, the prevalence and related factors of neck pain in military personnel have not been systematically investigated, which may lead to the lack of neck pain prevention and the generation of additional medical expenses, posing challenges to medical care. This review aimed to obtain the prevalence and related factors for neck pain in military personnel in an attempt to provide directions for prevention and intervention. Methods: We searched PubMed, Embase, and Cochrane databases in December 2021. Two researchers independently screened studies according to eligibility criteria and assessed study quality. Results: We screened titles and abstracts of 503 articles, and 17 articles met the inclusion criteria. Sixteen articles received moderate to high-quality evaluations. Neck pain is common in the military, with 1-year prevalence as high as 83% and lifetime prevalence as high as 78%. Old age (OR = 5.0), poor neck mobility (OR = 3.61), shoulder pain (OR = 4.9), low back pain (OR = 2.3), high-G pilots (OR = 1.6), longer flight time (OR = 2.53), type of aircraft (OR = 3.93), and use of helmets and night vision systems (OR = 1.9) may be associated with the prevalence of neck pain. Conclusion: Neck pain is highly prevalent in military personnel and exhibits a substantial lifetime prevalence rate. The high prevalence rate of neck pain in the military is related to many individual-related factors and work-related factors. The in-depth assessment and prevention of specific factors is an important direction of future research.

Impact of diffusion-weighted imaging on agreement between radiologists and non-radiologist in musculoskeletal tumor imaging using magnetic resonance.

Background: Diffusion-weighted imaging (DWI) is widely used in neuroradiology or abdominal imaging but not yet implemented in the diagnosis of musculoskeletal tumors. Aim: This study aimed to evaluate how including diffusion imaging in the MRI protocol for patients with musculoskeletal tumors affects the agreement between radiologists and non-radiologist. Methods: Thirty-nine patients with musculoskeletal tumors (Ewing sarcoma, osteosarcoma, and benign tumors) consulted at our institution were included. Three raters with different experience levels evaluated examinations blinded to all clinical data. The final diagnosis was determined by consensus. MRI examinations were split into 1) conventional sequences and 2) conventional sequences combined with DWI. We evaluated the presence or absence of diffusion restriction, solid nature, necrosis, deep localization, and diameter >4 cm as known radiological markers of malignancy. Agreement between raters was evaluated using Gwet's AC1 coefficients and interpreted according to Landis and Koch. Results: The lowest agreement was for diffusion restriction in both groups of raters. Agreement among all raters ranged from 0.51 to 0.945, indicating moderate to almost perfect agreement, and 0.772-0.965 among only radiologists indicating substantial to almost perfect agreement. Conclusion: The agreement in evaluating diffusion-weighted MRI sequences was lower than that for conventional MRI sequences, both among radiologists and non-radiologist and among radiologists alone. This indicates that assessing diffusion imaging is more challenging, and experience may impact the agreement.

Identification of a lumped-parameter model of the intervertebral joint from experimental data.

Through predictive simulations, multibody models can aid the treatment of spinal pathologies by identifying optimal surgical procedures. Critical to achieving accurate predictions is the definition of the intervertebral joint. The joint pose is often defined by virtual palpation. Intervertebral joint stiffnesses are either derived from literature, or specimen-specific stiffnesses are calculated with optimisation methods. This study tested the feasibility of an optimisation method for determining the specimen-specific stiffnesses and investigated the influence of the assigned joint pose on the subject-specific estimated stiffness. Furthermore, the influence of the joint pose and the stiffness on the accuracy of the predicted motion was investigated. A computed tomography based model of a lumbar spine segment was created. Joints were defined from virtually palpated landmarks sampled with a Latin Hypercube technique from a possible Cartesian space. An optimisation method was used to determine specimen-specific stiffnesses for 500 models. A two-factor analysis was performed by running forward dynamic simulations for ten different stiffnesses for each successfully optimised model. The optimisations calculated a large range of stiffnesses, indicating the optimised specimen-specific stiffnesses were highly sensitive to the assigned joint pose and related uncertainties. A limited number of combinations of optimised joint stiffnesses and joint poses could accurately predict the kinematics. The two-factor analysis indicated that, for the ranges explored, the joint pose definition was more important than the stiffness. To obtain kinematic prediction errors below 1 mm and 1° and suitable specimen-specific stiffnesses the precision of virtually palpated landmarks for joint definition should be better than 2.9 mm.

Systematic Review of the Psychopathological Symptomatology and Neuropsychological Disorders of Chronic Primary Musculoskeletal Pain.

Chronic pain can develop without tissue damage, injury, or underlying illness. There are several intervening biological, psychological, and social factors involved in its appearance that significantly affect the activities of daily life. It is also associated with significant emotional anxiety and/or functional disability. This review systematically analyses works published in the last five years that evaluate the psychopathological symptomatology and neuropsychological disorders of chronic primary musculoskeletal pain (CPMP). A bibliographic search was carried out to identify articles published in English between January 2018 and March 2023 using the Medline, Scopus, PsycInfo, and Pubmed databases. Twenty articles were obtained using the PRISMA selection method. The main results of this study provided evidence of the presence of moderate and severe chronic pain in patients suffering from musculoskeletal pain. This increase in the intensity of pain correlates with greater psychopathological symptomatology, such as depression, anxiety, insomnia, lack of attention, and hyperactivity/impulsiveness, as well as the use of maladaptive coping strategies. Furthermore, there exists dysfunction in the cerebral structures related to attention and the processing of pain in patients with CPMP. This review may help to develop and optimise the multidisciplinary treatments adapted to the deficits caused by this illness.

Transforming Veteran Rehabilitation Care: Learnings from a Remote Digital Approach for Musculoskeletal Pain.

While musculoskeletal pain (MSP) stands as the most prevalent health condition among Veterans, timely and high-quality care is often hindered due to access barriers. Team Red, White & Blue (Team RWB), a nonprofit organization dedicated to promoting a healthier lifestyle among Veterans, aimed to assess innovative approaches to veteran care. This is a single-arm pilot study investigating the feasibility, clinical outcomes, engagement, and satisfaction of a remote multimodal digital care program among Veterans with MSP. The impact of deployment experience on outcomes was explored as a secondary aim. From 75 eligible Veterans, 61 started the program, reporting baseline pain frequently comorbid with mental distress. Program acceptance was suggested by the high completion rate (82%) and engagement levels, alongside high satisfaction (9.5/10, SD 1.0). Significant improvements were reported in all clinical outcomes: pain (1.98 points, 95%CI 0.13; 3.84, p = 0.036); mental distress, with those reporting at least moderate baseline depression ending the program with mild symptoms (8.50 points, 95%CI: 6.49; 10.51, p = 0.012); daily activity impairment (13.33 points, 95%CI 1.31; 25.34, p = 0.030). Deployed Veterans recovered similarly to their counterparts. Overall, the above results underscore the potential of a remote digital intervention to expand Veterans' access to timely MSP care.

Registry-based cohort study comparing percentages of patients reaching PASS for knee function outcomes after revision ACLR compared to primary ACLR.

OBJECTIVES: Reaching the Patient-Acceptable Symptom State (PASS) threshold for the Knee injury and Osteoarthritis Outcome Score (KOOS) has previously been reported to successfully identify individuals experiencing clinical success after anterior cruciate ligament reconstruction (ACLR). Thus, the objectives of this study were to examine and compare the percentages of patients meeting PASS thresholds for the different KOOS subscales 1 year postoperatively after primary ACLR compared with revision ACLR (rACLR) and multiply revised ACLR (mrACLR), and second, to examine the predictors for reaching PASS for KOOS Quality of Life (QoL) and Function in Sport and Recreation (Sport/Rec) after mrACLR. DESIGN: Prospective observational registry study. SETTING: The data used in this study was obtained from the Swedish National Ligament Registry and collected between 2005 and 2020. PARTICIPANTS: The study sample was divided into three different groups: (1) primary ACLR, (2) rACLR and (3) mrACLR. Data on patient demographic, injury and surgical characteristics were obtained as well as mean 1-year postoperative scores for KOOS subscales and the per cent of patients meeting PASS for each subscale. Additionally, the predictors of reaching PASS for KOOS Sport/Rec, and QoL subscales were evaluated in patients undergoing mrACLR. RESULTS: Of the 22 928 patients included in the study, 1144 underwent rACLR and 36 underwent mrACLR. Across all KOOS subscales, the percentage of patients meeting PASS thresholds was statistically lower for rACLR compared with primary ACLR (KOOS Symptoms 22.5% vs 32.9%, KOOS Pain 84.9% vs 92.9%, KOOS Activities of Daily Living 23.5% vs 31.4%, KOOS Sport/Rec 26.3% vs 45.6%, KOOS QoL 26.9% vs 51.4%). Percentages of patients reaching PASS thresholds for all KOOS subscales were comparable between patients undergoing rACLR versus mrACLR. No predictive factors were found to be associated with reaching PASS for KOOS QoL and KOOS Sport/Rec 1 year postoperatively after mrACLR. CONCLUSION: Patients undergoing ACLR in the revision setting had lower rates of reaching acceptable symptom states for functional knee outcomes than those undergoing primary ACLR. LEVEL OF EVIDENCE: Prospective observational registry study, level of evidence II.

Development and Use of Mobile Messaging for Individuals With Musculoskeletal Pain Conditions: Scoping Review.

BACKGROUND: Population studies show that musculoskeletal conditions are a leading contributor to the total burden of healthy life lost, second only to cancer and with a similar burden to cardiovascular disease. Prioritizing the delivery of effective treatments is necessary, and with the ubiquity of consumer smart devices, the use of digital health interventions is increasing. Messaging is popular and easy to use and has been studied for a range of health-related uses, including health promotion, encouragement of behavior change, and monitoring of disease progression. It may have a useful role to play in the management and self-management of musculoskeletal conditions. OBJECTIVE: Previous reviews on the use of messaging for people with musculoskeletal conditions have focused on synthesizing evidence of effectiveness from randomized controlled trials. In this review, our objective was to map the musculoskeletal messaging literature more broadly to identify information that may inform the design of future messaging interventions and summarize the current evidence of efficacy, effectiveness, and economics. METHODS: Following a prepublished protocol developed using the Joanna Briggs Institute Manual for Evidence Synthesis, we conducted a comprehensive scoping review of the literature (2010-2022; sources: PubMed, CINAHL, Embase, and PsycINFO) related to SMS text messaging and app-based messaging for people with musculoskeletal conditions. We described our findings using tables, plots, and a narrative summary. RESULTS: We identified a total of 8328 papers for screening, of which 50 (0.6%) were included in this review (3/50, 6% previous reviews and 47/50, 94% papers describing 40 primary studies). Rheumatic diseases accounted for the largest proportion of the included primary studies (19/40, 48%), followed by studies on multiple musculoskeletal conditions or pain sites (10/40, 25%), back pain (9/40, 23%), neck pain (1/40, 3%), and "other" (1/40, 3%). Most studies (33/40, 83%) described interventions intended to promote positive behavior change, typically by encouraging increased physical activity and exercise. The studies evaluated a range of outcomes, including pain, function, quality of life, and medication adherence. Overall, the results either favored messaging interventions or had equivocal outcomes. While the theoretical underpinnings of the interventions were generally well described, only 4% (2/47) of the papers provided comprehensive descriptions of the messaging intervention design and development process. We found no relevant economic evaluations. CONCLUSIONS: Messaging has been used for the care and self-management of a range of musculoskeletal conditions with generally favorable outcomes reported. However, with few exceptions, design considerations are poorly described in the literature. Further work is needed to understand and disseminate information about messaging content and message delivery characteristics, such as timing and frequency specifically for people with musculoskeletal conditions. Similarly, further work is needed to understand the economic effects of messaging and practical considerations related to implementation and sustainability.
