Hand-transmitted vibration (HTV) exposure is associated with various health risks for operators of mobile mining equipment (MME). The case–control research was conducted to determine the musculoskeletal disorder (MSD) risks associated with exposure to HTVs in the exposed (case) and non-exposed (control) groups. HTV readings were measured at the interface between the hand and the steering device using the SV 105B triaxial hand accelerometer connected to the SV106 human vibration analyzer involving 40 MME operators in accordance with ISO 5349:2001 guidelines. A questionnaire survey was also carried out among both the study groups using Cornell Musculoskeletal Discomfort Questionnaire. The European Union's 2002/44/E.C. was used to assess the health risks posed to the MME operators. Twenty-eight out of the 40 MMEs were generating HTVs exceeding the stipulated daily limits of vibration, putting 70% of the operators at increased risk for developing MSDs. The case group was found to have an elevated risk of exposure with odds ratio (OR) 7.56 (95% confidence interval (CI), 1.159, 49.39) and OR 12.80 (95% CI, 2.436, 67.285) times more likely than the control group to suffer discomfort in the left shoulder and left wrist, respectively, indicating increased risk of exposure to HTV. Additionally, cases had elevated risk associated with exposure to tobacco, OR 9.35(95% CI, 1.856, 47.129) compared to those who did not use tobacco. MSDs were more prevalent in the case group compared to the control group. This observation was validated by the field investigations and the responses of MME operators to the questionnaires.

手传振动 (HTV) 暴露与移动采矿设备 (MME) 操作员的各种健康风险有关。进行病例对照研究以确定与暴露（病例）和未暴露（对照组）组中的 HIV 暴露相关的肌肉骨骼疾病 (MSD) 风险。根据 ISO 5349:2001 指南，使用连接到 SV106 人体振动分析仪的 SV 105B 三轴手加速度计在手和转向装置之间的界面处测量 HTV 读数，该分析仪涉及 40 名 MME 操作员。还使用康奈尔肌肉骨骼不适问卷在两个研究组中进行了问卷调查。欧盟的 2002/44/EC 用于评估对 MME 经营者构成的健康风险。40 家 MME 中有 28 家产生的 HTV 超过了规定的每日振动限制，这使 70% 的运营商患 MSD 的风险增加。发现病例组的暴露风险升高，优势比（OR ) 7.56 (95% CI , 1.159, 49.39) 和OR 12.80 (95% CI , 2.436, 67.285) 倍，分别比对照组的左肩和左手腕出现不适，表明增加暴露于 HIV 的风险。此外，与不使用烟草的病例相比，病例与接触烟草相关的风险增加，OR 9.35（95% CI ，1.856, 47.129）。与对照组相比，病例组的 MSD 更为普遍。这一观察得到了实地调查和 MME 运营商对问卷的答复的验证。
