| چکیده | ||
| روش سنتی یا بهره برداری متکی به کارگر، هنوز به‌عنوان اساس عملیات جنگلداری در برخی از کشورهای دنیا ایفای نقش می‌کند. بارگیری دستی بار توسط کارگر، که عامل ایجاد کنندۀ خطرات زیاد برای سلامت و ایمنی شغلی کارگران و میزان مرگومیر بالا در کارگران است، سبب ایجاد شدیدترین اختلالات اسکلتی-عضلانی مرتبط با کار (WMSD) در این کارگران در بین تمام مشاغل جنگلداری می شود. این پژوهش با هدف ارزیابی میزان شیوع و بروز اختلالات اسکلتی-عضلانی مرتبط با کار، در کارگران بارگیری دستی بار شاغل در عملیات بهره برداری از جنگل در سری های 1 و 2 صنوبرکاری شدۀ منطقۀ تنیان، در حومۀ شهرستان صومعه سرا در استان گیلان، با رویکرد ارگونومی شغلی انجام گرفت. جامعۀ آماری این پژوهش، متشکل از 40 نفر از کارگران شاغل به کار بارگیری دستی گرده بینه در عملیات بهره برداری از صنوبرکاری‌ها بود که جهت اندازه گیری شیوع و بروز اختلالات اسکلتی–عضلانی در کارگران مورد مطالعه از روش دموگرافیک، پرسشنامۀ نوردیک و روش پزشکی مقیاس نرخگذاری آنالوگ بصری استفاده شد. نتایج نشان داد که در طول یک سال گذشته، اختلالات اسکلتی–عضلانی با میزان درد شدیدی با شاخص امتیاز درد (9-7) در 46/38درصد از کارگران و با بیشترین میزان شیوع و بروز در اندام های کمر، ستون فقرات و مچ دست بدن کارگران به‌طرز چشمگیری افزایش یافته است. | ||

| چکیده [English] | ||
| Traditional, labor-intensive methods still form the foundation of forestry operations in some countries. Manual loading of logs by workers—an activity that poses high health and safety risks and contributes to elevated mortality rates—is responsible for the most severe work-related musculoskeletal disorders (WMSDs) among all forestry occupations. This study aimed to evaluate the prevalence and incidence of WMSDs in manual loading workers engaged in forest harvesting operations in Series 1 and 2 of poplar plantations in the Tanian area, a suburb of Soumeh-Sara County in Guilan Province, northern Iran. The study population consisted of 40 workers involved in manually loading poplar logs during harvesting operations. The tasks performed by these workers included approaching the logs, lifting, carrying them to the truck, and manually loading them in nine distinct loading cycles. To measure the prevalence and incidence of musculoskeletal disorders, demographic data, the Nordic Musculoskeletal Questionnaire, and the medical visual analog scale (VAS) method were used. The findings showed that in the past year, 46.38% of workers experienced severe musculoskeletal pain (pain score of 7–9), with the highest rates of prevalence and incidence observed in the lower back, spine, and wrists. Ergonomic risks and occupational health problems among manual laborers in poplar plantations of northern Iran represent a serious and under-recognized issue. | ||
