Abstract
Background Randomized controlled trials (RCTs) are crucial in comparative research, and a careful approach to randomization methodology helps minimize bias. However, confounding variables like socioeconomic status (SES) and race are often underreported in orthopaedic RCTs, potentially affecting the generalizability of results. This study aimed to analyze the reporting trends of SES and race in RCTs pertaining to Achilles tendon pathology, considering 4 decades of data from top-tier orthopaedic journals. Methods This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and used PubMed to search 10 high-impact factor orthopaedic journals for RCTs related to the management of Achilles tendon pathology. The search encompassed all articles from the inception of each journal until July 11, 2023. Data extraction included year of publication, study type, reporting of SES and race, primary study location, and intervention details. Results Of the 88 RCTs identified, 68 met the inclusion criteria. Based on decade of publication, 6 articles (8.8%) reported on SES, whereas only 2 articles (2.9%) reported on race. No RCTs reported SES in the pre-1999 period, but the frequency of reporting increased in subsequent decades. Meanwhile, all RCTs reporting race were published in the current decade (2020-2030), with a frequency of 20%. When considering the study location, RCTs conducted outside the United States were more likely to report SES compared with those within the USA. Conclusion This review revealed a concerning underreporting of SES and race in Achilles tendon pathology RCTs. The reporting percentage remains low for both SES and race, indicating a need for comprehensive reporting practices in orthopaedic research. Understanding the impact of SES and race on treatment outcomes is critical for informed clinical decision making and ensuring equitable patient care. Future studies should prioritize the inclusion of these variables to enhance the generalizability and validity of RCT results.

Testing the Level of Agreement between Two Methodological Approaches of the Rapid Upper Limb Assessment (RULA) for Occupational Health Practice-An Exemplary Application in the Field of Dentistry. Bioengineering (Basel) 2023; 10:bioengineering10040477. [PMID: 37106664 PMCID: PMC10136304 DOI: 10.3390/bioengineering10040477] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 04/11/2023] [Accepted: 04/12/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND The Rapid Upper Limb Assessment (RULA) is used for the risk assessment of workplace-related activities. Thus far, the paper and pen method (RULA-PP) has been predominantly used for this purpose. In the present study, this method was compared with an RULA evaluation based on kinematic data using inertial measurement units (RULA-IMU). The aim of this study was, on the one hand, to work out the differences between these two measurement methods and, on the other, to make recommendations for the future use of the respective method on the basis of the available findings. METHODS For this purpose, 130 (dentists + dental assistants, paired as teams) subjects from the dental profession were photographed in an initial situation of dental treatment and simultaneously recorded with the IMU system (Xsens). In order to compare both methods statistically, the median value of the difference of both methods, the weighted Cohen's Kappa, and the agreement chart (mosaic plot) were applied. RESULTS In Arm and Wrist Analysis-area A-here were differences in risk scores; here, the median difference was 1, and the agreement in the weighted Cohen's kappa test also remained between 0.07 and 0.16 (no agreement to poor agreement). In area B-Neck, Trunk, and Leg Analysis-the median difference was 0, with at least one poor agreement in the Cohen's Kappa test of 0.23-0.39. The final score has a median of 0 and a Cohen's Kappa value of 0.21-0.28. In the mosaic plot, it can be seen that RULA-IMU had a higher discriminatory power overall and more often reached a value of 7 than RULA-PP. CONCLUSION The results indicate a systematic difference between the methods. Thus, in the RULA risk assessment, RULA-IMU is mostly one assessment point above RULA-PP. Therefore, future study results of RULA by RULA-IMU can be compared with literature results obtained by RULA-PP to further improve the risk assessment of musculoskeletal diseases.

Abstract
Background Shoulder pain, which is a widespread condition, can lead to participation restrictions in daily and professional life. However, there are few studies focusing on the differences between daily life limitations and work limitations. This study aims at identifying the factors associated with limitations in personal and professional life in a population of working age suffering from shoulder pain. Methods A sample of working age job seekers and workers with shoulder pain was drawn from the last general population cross-sectional French study on disability. Limitations were categorized depending on whether they related to daily life and/or work. The variables assessed were age, sex, state of health, activity restrictions, need for accommodation, and aggravating living conditions or aggravating working conditions. Separate Quasi-Poisson regressions were performed for each type of limitation. Results The sample consisted of 795 individuals of which 33.7% had no limitation, 21.7% were limited in daily life, 6.0% at work, and 38.6% in both. Factors significantly associated with daily life limitations and work limitations and their computed Prevalence Ratios (PR) were the need for accommodation (PR = 2.16), activity restrictions (PR = 2.28), perceived poor health (PR = 2.42) and low income (PR = 1.64). Aggravating living conditions and aggravating working conditions were associated with daily life limitations (PR of 1.69 and 0.63 respectively). Conclusions The present study identifies factors associated with disability in a population with shoulder pain. Further research should be carried out in order to study health-related periods of cessation of work.

Impact of chronic Achilles tendinopathy on health-related quality of life, work performance, healthcare utilisation and costs. BMJ Open Sport Exerc Med 2021; 7:e001023. [PMID: 33868707 PMCID: PMC8006822 DOI: 10.1136/bmjsem-2020-001023] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/17/2021] [Indexed: 12/12/2022] Open
Abstract
Objectives To evaluate the impact of Achilles tendinopathy (AT) on quality of life (QoL), work performance, healthcare utilisation and costs in adults with conservatively treated chronic midportion AT. Methods This cross-sectional survey-based study included 80 patients and took place in a sports medicine department of a large regional hospital in the Netherlands. Data were collected before any intervention was given. Primary outcome was the EuroQol questionnaire (EQ-5D). The EQ-5D expresses the percentage of moderate/major problems on the domains self-care, anxiety/depression, mobility, usual activities and pain/discomfort. Secondary outcomes were the number of previous healthcare visits, work performance during the period of symptoms and estimated annual direct medical and indirect costs per patient as a result of AT. Results All 80 patients completed the questionnaires. The EQ-5D scores were low for the domains self-care (1%) and anxiety/depression (20%), and high for the domains mobility (66%), usual activities (50%) and pain/discomfort (89%). Patients with AT mainly reported an impact on work productivity (38%). Work absenteeism due to AT was present in 9%. The total median (IQR) number of annual healthcare visits was 9 (3-11). The total mean (SD) estimated annual costs were €840 (1420) per patient with AT (mean (SD) US$991 (1675)). Conclusions This study shows the large impact of AT on QoL and work productivity. This study also provides new information about the socioeconomic impact of AT, which emphasises that this common and longstanding disease causes substantial costs. These findings stress the need for optimised treatment and improved preventive interventions for AT. Trial registration number NCT02996409.

Abstract
There is little data delineating relationships between health and worker musculoskeletal symptoms (MSS), particularly among stone, sand, and gravel mine (SSGM) workers. There is also little data detailing the relationships between physical activity and MSS among these workers. A cross-sectional study using data from 459 SSGM workers was completed. Logistic regression analyses assessed relationships between health factors, physical activity, and low back, neck, shoulder, and knee MSS. Those who reported their health as very good/excellent were less likely to suffer low back and knee MSS. Those who indicated their health was poor/fair were more likely to suffer shoulder, neck, and knee MSS. Obese workers were more likely to experience knee MSS and those who smoked in the past had higher odds of neck MSS. Vigorous physical activity was mostly protective, but those performing more than 5 h of moderate physical activity each week had greater odds of shoulder and neck MSS. Given these results, workers in SSGM may benefit from targeted interventions that bolster vigorous physical activity and improve health. Further, health protection efforts need to be initiated by SSGM operations to address work issues and to sustain health as job roles and work hours impacted MSS as well.

Abstract
Introduction l’épicondylite latérale, mieux connue sous le nom de « Tennis elbow », fait partie des troubles musculo-squelettiques du membre supérieur et constitue un problème majeur de santé publique. Le but de notre étude est d'évaluer le profil épidémio-clinique et les modalités thérapeutiques des patients suivis au service de médecine physique et réadaptation, pour épicondylite latérale. Méthodes il s'agit d'une étude rétrospective sur 6 ans (2012-2017) portant sur des patients adressés au Service de Médecine Physique et de Réadaptation Fonctionnelle au CHU Tahar Sfar Mahdia pour une épicondylite latérale. Les caractéristiques sociodémographiques et cliniques ainsi que les modalités thérapeutiques ont été évalués pour chaque patient. Résultats cinquante patients ont été inclus. L’âge moyen était de 44,82 ans, avec une prédominance féminine (72%). La moitié de nos patients étaient actifs et la majorité (60%) effectuait un travail type bureautique. Le membre supérieur droit était le plus touché dans 78% des cas. La durée moyenne des symptômes était de 14,66 mois. L’examen clinique a révélé une triade tendineuse positive, au niveau des épicondyliens latéraux dans 96% des cas. L’examen radiologique a été réalisé pour 8 patients, et l’échographie pour 6 patients. Tous les patients ont reçu un traitement antalgique, 84% des patients ont reçu des anti-inflammatoires non stéroïdiens et seulement 8 patients ont bénéficié d’une infiltration de corticoïdes. Un seul patient a bénéficié d’un traitement chirurgical après échec de la prise en charge médicale. Des séances de rééducation ont été prescrites chez 92% des patients. Une amélioration totale a été notée chez 42% des patients, 46% ont rapporté une amélioration transitoire et 12% ont évolué vers la chronicité. Conclusion l’épicondylite latérale est une source fréquente de douleur du coude. Sa prise en charge en Médecine Physique repose sur un traitement médical et une rééducation fonctionnelle adaptée. Mais aucune option thérapeutique ne semble être clairement supérieure à l’autre.

Abstract
BACKGROUND Musculoskeletal disorders (MSD) are a significant problem in the oral health profession. This study explores oral health professionals' physical and psychosocial working environments in Australian workplaces. METHOD Twelve oral health professionals from the public and private dental sectors participated in semi-structured interviews. Interviews were recorded and transcribed. Themes were identified and a coding framework developed which was refined and clarified during analysis. RESULTS Participants reported a range of physical and psychosocial experiences in their work environment. Three major categories of themes were identified: Job Characteristics - particularly equipment unsuited for task and time constraints; Job Satisfaction - support from management and colleagues was valued, as was the significance of providing oral health care, particularly to children and minority groups; and Individual Factors - MSD and fatigue were reported by most participants. CONCLUSION Oral health professionals are exposed to a range of workplace physical and psychosocial hazards associated with the development of MSDs. Risk management programs for the prevention of MSDs should take into account the range of physical and psychosocial hazards that oral health professionals are exposed to.

Abstract
Objective To examine the impact of a disabling non-traumatic shoulder lesion on work participation and working life expectancy. Methods From a 70% random sample of the Finnish population, we selected 30–59-year-old wage earners with prolonged sickness absence due to a shoulder lesion (n=7644). We followed the persons from 2006 to 2014 and calculated the proportion of time a person spent in different work participation statuses. The associations of potential determinants with a preterm exit from paid employment were tested using Cox regression. Years expected to be spent in different work participation statuses were estimated applying the Sullivan method for healthy life expectancy. Results During 9 years of follow-up time spent at work was reduced from 77.7% to 46.7%, and 15.8% of the persons were granted disability retirement, mostly due to shoulder and other musculoskeletal diseases. Compared with the general population persons with a disabling shoulder disease are expected to lose from 1.8 to 8.1 years of working life, depending on their age. Age, gender, education, duration of initial sickness absence due to the shoulder lesion, not being able to return to work sustainably and participation in vocational rehabilitation predicted preterm exit from work. Heavy lifting increased the risk of preterm exit marginally. Conclusions Working life expectancy is markedly reduced in persons with a disabling shoulder lesion, mainly because of disability retirement due to musculoskeletal problems. Clinicians should consider interventions targeted at improving musculoskeletal functioning and necessary work modifications before shoulder problems become chronic or the persons develop disabling comorbid musculoskeletal conditions.

Abstract
Musculoskeletal pain among professionals in the transport sector has been linked to working conditions. The scope of this study was to assess the prevalence of cervical musculoskeletal pain and its relation to pain in other areas (arms, hands and shoulders). The association between neck pain, related to pain in other areas or otherwise, was checked against occupational factors. A cross-sectional, descriptive and analytical study was conducted with 799 bus drivers and 708 fare collectors of the Metropolitan Region of Belo Horizonte, Brazil. The outcome was characterized according to the positive answer to the question about musculoskeletal pain in the anatomical areas studied. The prevalence of neck pain in the sample was highest at 16.3%, followed by pain in the shoulders 15.4%, arms 13.3% and hands 6.3%. The factors associated with musculoskeletal pain in the sample were being female, complaints of disability, perception of threat to safety, vibration, excessive or unbearable noise and sitting in an uncomfortable posture. The results provide clues to transformation of the workplace, thereby contributing to the enhancement of occupational health.

Abstract
OBJECTIVE The goal is to assess the relationships between psychosocial factors and both medial and lateral epicondylitis after adjustment for personal and job physical exposures. METHODS One thousand eight hundred twenty-four participants were included in pooled analyses. Ten psychosocial factors were assessed. RESULTS One hundred twenty-one (6.6%) and 34 (1.9%) participants have lateral and medial epicondylitis, respectively. Nine psychosocial factors assessed had significant trends or associations with lateral epicondylitis, the largest of which was between physical exhaustion after work and lateral epicondylitis with and odds ratio of 7.04 (95% confidence interval = 2.02 to 24.51). Eight psychosocial factors had significant trends or relationships with medial epicondylitis, with the largest being between mental exhaustion after work with an odds ratio of 6.51 (95% confidence interval = 1.57 to 27.04). CONCLUSIONS The breadth and strength of these associations after adjustment for confounding factors demonstrate meaningful relationships that need to be further investigated in prospective analyses.

Abstract
Objective Many workers suffer from musculoskeletal disorders. In France, occupational physicians are able to set job aptitude restrictions obliging employers to adapt the worker's job. The present study explored the impact of job restriction from the point of view of the employees' supervisors. Methods A qualitative study was conducted in 3 public hospitals. 12 focus groups were organized, involving 61 charge nurses and head nurses supervising 1 or more workers restricted for heavy lifting or repetitive movements. Discussions were recorded for qualitative thematic analysis. Results Charge and head nurses complained that aptitude restrictions were insufficiently precise, could not be respected and failed to mention residual capability. A context of personnel cuts, absenteeism and productivity demands entailed a need for polyvalence and reorganization threatening the permanence of adapted jobs. Job restrictions had several negative consequences for the charge and head nurses, including overwork, increased conflict, and feelings of isolation and organizational injustice. Conclusion Protecting the individual interests of workers with health issues may infringe on the interests of their supervisors and colleagues, whose perception of organizational justice may go some way to explaining the support or rejection they show toward restricted workers. This paradox should be explicitly explored and discussed.

Abstract
There are currently no studies that determine the total burden that tendinopathy places on patients and society. A systematic search was conducted to understand the impact of tendinopathy. It demonstrated that the current prevalence is underestimated, particularly in active populations, such as athletes and workers. Search results demonstrate that due to the high prevalence, impact on patients' daily lives and the economic impact due to work-loss, treatments are significantly higher than currently observed. A well-accepted definition by medical professionals and the public will improve documentation and increase awareness, in order to better tackle the disease burden.

Abstract
BACKGROUND Psychosocial factors at work (PFW) can be defined as all non-physicochemical occupational risks. Several epidemiological models have been proposed to measure PFW, but one of the most widely used is Karasek's model. AIMS To determine whether psychosocial factors, evaluated by Karasek's questionnaire, had increased in a cohort of workers. METHODS A random sample of workers in the Pays de la Loire region of France, who could be considered representative of the region's population of salaried workers, filled in a self-administered questionnaire, including Karasek's self-administered questionnaire, in 2002-05 and 2007-09. Karasek's questionnaire can be used to study three psychosocial dimensions (psychological demand, decision latitude and social support in the workplace) in workers in order to define two high-risk situations for their health: 'Job Strain' and 'Iso Strain'. Changes in job strain and iso strain among workers were studied according to the workers' sociodemographic characteristics and their working conditions. RESULTS In this sample of 2049 workers, the proportion with iso strain increased between the two periods from 12 to 16%, P < 0.001, mainly among manual workers. Deterioration of Karasek indicators was mainly explained by an increase of the 'low social support' dimension (38 versus 49%, P < 0.001). Working conditions such as temporary employment of colleagues and high perceived physical exertion were associated with higher PFW. CONCLUSIONS This study, based on a quantitative and collective model, showed deterioration of working team environments and increased risk for individual mental health in this cohort of French workers in recent years.

Is the Control of Applied Digital Forces During Natural Five-digit Grasping Affected by Carpal Tunnel Syndrome? Clin Orthop Relat Res 2015; 473:2371-82. [PMID: 25690168 PMCID: PMC4457761 DOI: 10.1007/s11999-015-4189-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2014] [Accepted: 02/03/2015] [Indexed: 02/09/2023]
Abstract
BACKGROUND The impaired sensory function of the hand induced by carpal tunnel syndrome (CTS) is known to disturb dexterous manipulations. However, force control during daily grasping configuration among the five digits has not been a prominent focus of study. Because grasping is so important to normal function and use of a hand, it is important to understand how sensory changes in CTS affect the digit force of natural grasp. QUESTIONS/PURPOSES We therefore examined the altered patterns of digit forces applied during natural five-digit grasping in patients with CTS and compared them with those seen in control subjects without CTS. We hypothesized that the patients with CTS will grasp by applying larger forces with lowered pair correlations and more force variability of the involved digits than the control subjects. Specifically, we asked: (1) Is there a difference between patients with CTS and control subjects in applied force by digits during lift-hold-lower task? (2) Is there a difference in force correlation coefficient of the digit pairs? (3) Are there force variability differences during the holding phase? METHODS We evaluated 15 female patients with CTS and 15 control subjects matched for age, gender, and hand dominance. The applied radial forces (Fr) of the five digits were recorded by respective force transducers on a cylinder simulator during the lift-hold-lower task with natural grasping. The movement phases of the task were determined by a video-based motion capture system. RESULTS The applied forces of the thumb in patients with CTS (7 ± 0.8 N; 95% CI, 7.2-7.4 N) versus control subjects (5 ± 0.8 N; 95% CI, 5.1-5.3 N) and the index finger in patients with CTS (3 ± 0.3 N; 95% CI, 3.2-3.3 N) versus control subjects (2 ± 0.3 N; 95% CI, 2.2-2.3 N) observed throughout most of the task were larger in the CTS group (p ranges 0.035-0.050 for thumb and 0.016-0.050 for index finger). In addition, the applied force of the middle finger in patients with CTS (1 ± 0.1 N; 95% CI, 1.3-1.4 N) versus the control subjects (2 ± 0.2 N; 95% CI, 1.9-2.0 N) during the lowering phase was larger in CTS group (p ranges 0.039-0.050). The force correlations of the thumb-middle finger observed during the lowering phase in the patients with CTS (0.8 ± 0.2; 95% CI, 0.6-0.9) versus the control subjects (0.9 ± 0.1; 95% CI, 0.8-1.0; p = 0.04) were weaker in the CTS group. The thumb-little finger during holding in the patients with CTS (0.5 ± 0.2; 95% CI, 0.3-0.7) versus the control subjects (0.8 ± 0.2; 95% CI, 0.6-0.9; p = 0.02), and the lowering phase in the patients with CTS (0.6 ± 0.2; 95% CI, 0.3-0.8) versus the control subjects (0.9 ± 0.1; 95% CI, 0.8-1.0; p = 0.01) also were weaker. The force variabilities of patients with CTS were greater in the CTS group than in the control subjects: in the thumb ([0.26 ± 0.11 N, 95% CI, 0.20-0.32 N] versus [0.19 ± 0.06 N; 95% CI, 0.16-0.22 N], p = 0.03); index finger ([0.09 ± 0.07 N; 95% CI, 0.05-0.13 N] versus [0.05 ± 0.03 N; 95% CI, 0.04-0.07 N], p = 0.03); middle finger ([0.06 ± 0.04 N; 95% CI, 0.04-0.08 N] versus [0.03 ± 0.01 N; 95% CI, 0.02-0.04 N], p = 0.02), and ring finger ([0.04 ± 0.03 N; 95% CI, 0.20-0.06 N] versus [0.02 ± 0.01 N; 95% CI, 0.02-0.02 N], p = 0.01). CONCLUSIONS Patients with CTS grasped with greater digit force associated with weaker correlation and higher variability on specific digits in different task demands. These altered patterns in daily grasping may lead to secondary problems, which will need to be assessed in future studies with this model to see if they are reversible in patients undergoing carpal tunnel release. CLINICAL RELEVANCE The current results helped to identify altered patterns of grasping force during simulated daily function in patients with CTS and to provide the clinician with potential information that might help guide the rehabilitation of grasp in these patients.

Abstract
OBJECTIVE To examine the incidence and risk factors for incident thoracic spine pain (TSP) in workers representative of a French region's working population. METHODS In this prospective study, 3,710 workers were assessed in 2002-2005, and 2,332 (62.9%) of them were reassessed in 2007-2010. TSP was assessed by a self-administered Nordic questionnaire at baseline and at followup. At baseline, all participants completed a self-administered questionnaire on personal factors and work exposure. A total of 1,886 subjects (1,124 men and 762 women) without TSP at baseline were eligible for analysis. Associations between incident TSP and risk factors at baseline were analyzed by multivariate logistic regression. RESULTS The incidence rate of TSP was 5.2 (95% confidence interval [95% CI] 3.9-6.6) per 100 men and 10.0 (95% CI 7.8-12.1) per 100 women. TSP was often associated with low back pain and neck pain. TSP in men was associated with age (odds ratios [ORs] ranging from 2.6 [95% CI 0.95-7.1] at 30-39 years to 6.0 [95% CI 2.1-17.3] at ≥50 years), being tall (OR 2.2 [95% CI 1.2-3.9]), frequent/sustained trunk bending (OR 3.0 [95% CI 1.5-6.1]), lack of recovery period or change in the task (OR 2.0 [95% CI 1.2-3.6]), and driving vehicles (OR 2.8 [95% CI 1.4-5.5]). Being overweight or obese was associated with lower risk (OR 0.5 [95% CI 0.3-0.96]). TSP in women was associated with high perceived physical workload (OR 1.9 [95% CI 1.1-3.3]), after adjustment for confounding variables. CONCLUSION The risk model of TSP combined personal and work-related organizational and physical factors. Trunk bending appeared to be a strong independent predictor of TSP in this working population.

Abstract
INTRODUCTION Musculoskeletal disorders (MSDs) are among the most frequent causes of disability, with potentially important consequences. Our objective was to investigate from a lifelong perspective the factors associated with these consequences, including permanent withdrawal from the workforce, focusing especially on factors at the start of working life. METHODS The data come from the SIP national survey (Santé et Histoire Professionnelle, health and occupational history). Three groups of subjects were compared with multinomial logistic models: group 1 (G1), who had MSDs that caused an important event in their working life; group 2, who had MSDs without any such consequence; and group 3 (G3), who had no MSD. RESULTS In multivariate models, MSDs with consequences on occupational events were strongly associated with a low educational level for both sexes, and with some working conditions. In the comparison G1/G3, the odds-ratio (OR) for "no diploma" compared to "university level" was 4.41 and the confidence interval (95 % CI) 2.31-8.40 for men. For women the OR was 2.02 (95 % CI 1.32, 3.10). Group 2's educational level was between G1 and G3, closer to G3. For men, another risk factor was a first job in construction or farming (OR = 2.95 for construction, 2.23 for farming, comparison G1/G3). Comparisons focusing on "permanent withdrawal from the workforce" yielded similar results. CONCLUSIONS Associations between occupational history and health are complex; the results strongly suggest that factors at the beginning of working life, including level of education, have important delayed consequences, especially for workers with health disorders such as MDSs. In order to reduce the frequency of negative consequences, a better knowledge on causal mechanisms would be needed.
