摘要

与工作相关的肌肉骨骼疾病（MSDs）在农业生产者中很普遍。上肢，特别是肩部和颈部的msd是常见的，但对其发展和预防的研究有限。本研究旨在探讨肩部疼痛、年龄和性别对农场工作时肩部运动学的影响。方法招募萨斯喀彻温省的农民并将其分为有肩痛组和无肩痛组。参与者在佩戴惯性测量装置（imu）来跟踪肱骨和肩胛骨运动的同时，完成了四项任务（架空播种机、爬升播种机、种子袋提升和铲子）。数据分析采用线性回归和Kruskal-Wallis检验(p <；.05)评估疼痛、年龄和性别对肩关节运动的影响。结果42例受试者（无疼痛23例，有疼痛19例）完成研究。疼痛显著影响肩运动学在架空钻，种子袋提升和铲任务。在头顶训练期间，疼痛组的肩胛骨向上旋转幅度较大（p = 0.04, +5.1°），而女性的最大肱骨抬高幅度较小（p = 0.049, - 11.7°）。在种子袋提术中，疼痛组肩胛骨下向上旋转（p = 0.012,−18.7°），肱骨内旋转（p = 0.04, +12.0°）。在Shovel任务期间，疼痛组的肱骨抬高也较低（p = 0.019, - 12.7°）。结论：肩关节疼痛会影响农活任务中肩关节的运动学，并随任务的不同而变化。与疼痛相关的补偿可能是保护性的，也可能是有害的。这些发现强调了在农场工作的许多方面肩部受伤的潜在风险。

Shoulder pain influences kinematics during farm work tasks: An in-field study

Background

Work-related musculoskeletal disorders (MSDs) are prevalent among agricultural producers. Upper limb MSDs, especially in the shoulder and neck, are common, yet research on their development and prevention is limited. This study aims to investigate the influence of shoulder pain, age, and sex on shoulder kinematics during farm work tasks.

Methods

Farmers in Saskatchewan were recruited and divided into groups with and without shoulder pain. Participants performed four tasks (Overhead Drill, Climb Seeder, Seed Bag Lift, Shovel) while wearing inertial measurement units (IMUs) to track humeral and scapular movements. Data were analyzed using linear regression and Kruskal-Wallis tests (p < .05) to assess the effects of pain, age, and sex on shoulder kinematics.

Results

Forty-two participants (23 without pain, 19 with pain) completed the study. Pain significantly influenced shoulder kinematics during the Overhead Drill, Seed Bag Lift, and Shovel tasks. During the Overhead Drill, the pain group exhibited higher scapular upward rotation (p = .04, +5.1°) and females showed lower maximal humeral elevation (p = .049, −11.7°). In the Seed Bag Lift, the pain group had lower scapular upward rotation (p = .012, −18.7°) and higher humeral internal rotation (p = .04, +12.0°). Humeral elevation was also lower in the pain group during the Shovel task (p = .019, −12.7°).

Conclusions

Shoulder pain affects shoulder kinematics in farm work tasks, with variations depending on the task. Pain-related compensations can be both protective and harmful. These findings highlight the potential risk for shoulder injury in many aspects of farm work.
