While physical and biomechanical factors are well documented, the influence of psychological and behavioral variables—particularly obsessive passion for sport and sleep quality—remains underexplored in amateur populations. This study aimed to investigate the prevalence, location, and predictors of basketball-related injuries among Iranian amateur players, with a focus on mental factors and sleep quality.<br>Methods: A cross-sectional survey was conducted among 488 amateur basketball players. Data on demographics, training characteristics, injury history (past six months), obsessive passion, and sleep quality were collected. Injury was defined as any basketball-related physical problem causing ≥1 week of training/match cessation, ≥2 weeks of modified load, or requiring medical consultation. Univariate and multivariable logistic regression analyses were done to predict the variables.<br>Findings: Overall, 54.5% of players (N=266) reported at least one injury in the previous six months, most commonly affecting the ankle (21%; N=62) and knee (19.6%; N=58). Obsessive passion (OR = 1.58, 95% CI: 1.12–2.23, p = 0.009), poorer sleep quality (OR = 1.10, 95% CI: 1.02–1.19, p = 0.015), and >5 years’ experience (OR = 1.42, 95% CI: 1.01–2.00, p = 0.046) remained significant predictors, explaining 14% of the variance with 68% classification accuracy.<br>Conclusion: Injury risk among amateur basketball players is influenced not only by physical exposure but also by psychological commitment and recovery quality. Screening for obsessive passion and poor sleep may help identify at-risk athletes, enabling targeted interventions to optimize training load, recovery, and long-term participation.https://ijmpp.modares.ac.ir/article_28027_487cbe45b70fc4e83a1dd07546649e34.pdfTarbiat Modares UniversityInternational Journal of Musculoskeletal Pain Prevention2476-527910420251225Ergonomic Risk Assessment of Manual Drilling in an Underground Copper Mine: Fatigue Assessment131013162802610.48311/ijmpp.2025.117112.82905ENMohammadNegahdaryDepartment of Occupational Health and Safety Engineering, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iranfvhd0009-0008-4879-9815OmranAhmadiDepartment of Occupational Health and Safety Engineering, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, IranfvhdJournal Article20251105Aims: This study evaluated manual drilling to identify high-risk activities and quantify the risks of muscle fatigue and cumulative low back injury.<br>Method and Materials: This descriptive study involved direct observation of a full work shift. Three tools were used including Hierarchical Task Analysis (HTA) to deconstruct and time tasks, Muscle Fatigue Assessment (MFA) to identify high-risk body parts, and the Lifting Fatigue Failure Tool (LIFFT) to calculate cumulative damage to the low back from lifting tasks.<br>Findings: The HTA revealed that the drilling the wall task was the most time-consuming, accounting for 50% of the total shift time. The MFA results identified this task as posing a very high risk priority for the shoulders and back, and a high risk for the wrists/hands/fingers. The LIFFT analysis yielded a cumulative damage score of 0.09895, which corresponds to an approximate 67% probability of low back injury, classifying the job as high-risk. The tasks of drilling and moving tools contributed to over 99% of the total cumulative damage.<br>Conclusion: Manual drilling is a high-risk occupation with significant ergonomic hazards for the shoulder, back, and upper limbs. The alignment of these results with epidemiological data validates the assessment. Targeted interventions to reduce biomechanical loading are strongly recommended to mitigate the high risk of musculoskeletal disorders.https://ijmpp.modares.ac.ir/article_28026_21353d3d417eb49d01e341ef047696ae.pdfTarbiat Modares UniversityInternational Journal of Musculoskeletal Pain Prevention2476-527910420251225Ergonomic Risk Assessment of Kitchen Workers: CMDQ and Manual Lifting Analysis131713232802210.48311/ijmpp.2025.116673.82900ENMohammadNegahdaryDepartment of Occupational Health and Safety Engineering, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, Iranfvhd0009-0008-4879-9815SinaAlirezaeiDepartment of Occupational Health and Safety Engineering, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, IranfvhdOmranAhmadiDepartment of Occupational Health and Safety Engineering, Faculty of Medical Sciences, Tarbiat Modares University, Tehran, IranfvhdJournal Article20251029Aims: This study provides a comprehensive ergonomic assessment in a kitchen, combining subjective and objective measures.<br>Method and Materials: In this cross-sectional study, kitchen staffs completed the Farsi version of Cornell Musculoskeletal Discomfort Questionnaire (CMDQ). Hierarchical Task Analysis (HTA) broke down tasks to identify key physical demands. Manual handling tasks were evaluated using National Institute for Occupational Safety and Health (NIOSH), Washington Industrial Safety and Health Act (WISHA), Key Indicator Methods (KIM), and Manual Handling Assessment (MAC). Cohen’s Kappa (κ) assessed inter-method agreement.<br>Findings: The CMDQ revealed highest discomfort in the lower back region (11.33 ± 8.38) and right shoulder (11.00 ± 5.62). Objective tools identified several tasks as high risk: the Rice Cook's handling of 50kg rice containers (NIOSH Lifting Index (LI)=3.4; KIM Score=56, Risk Level 3) and 40kg rice strainers (NIOSH LI=5.48; KIM Score=132, Risk Level 4), and the Stew Cook's preparation of food in 30kg pans (NIOSH LI=3.56; KIM Score=41, Risk Level 2). Inter-method agreement (κ) was moderate to good between WISHA and NIOSH (κ=0.4942) and between MAC and KIM (κ=0.5170). NIOSH showed fair agreement with KIM (κ=0.2540) and slight agreement with MAC (κ=0.1960). WISHA’s agreement with MAC and KIM was very slight (κ=0.0837 and κ=0.1143 respectively).<br>Conclusion: kitchen tasks pose significant ergonomic risks, aligning with reported lumbar and shoulder discomfort. The varied agreement among MMH tools emphasizes the value of a multi-method approach for comprehensive risk assessment. Ergonomic interventions like load reduction and workstation adjustments are recommended.https://ijmpp.modares.ac.ir/article_28022_1c7501e5cf59a9b7b371f9d76a67c03b.pdfTarbiat Modares UniversityInternational Journal of Musculoskeletal Pain Prevention2476-527910420251225Presentation of a Causal Model of Athletic Success Based on Positive Psychological Experiences and Achievement Motivation with the Mediating Role of Self-Esteem in Student Athletes132413322802310.48311/ijmpp.2025.116839.82902ENAliJalili ShishavanDepartment of Sport Psychology, Allameh Tabataba'i University, Tehran, IranJournal Article20251028Aims:The objective was to construct a causal model to investigate the direct and indirect effects of positive psychological experiences and achievement motivation on athletic success, with self-esteem serving as a mediating factor, among elite student athletes.<br>Method and Materials:A sample of 230 elite student athletes was selected through random sampling.
