Abstract

BACKGROUND

Most of the people associated with tailoring occupation in Nepal are still using mechanical sewing machine as an alternative of new technology for tailoring. Common peroneal nerves of both right and left legs are exposed to strenuous and chronic stress exerted by vibration and paddling of mechanical sewing machine.

METHODS

The study included 30 healthy male tailors and 30 healthy male individuals. Anthropometric variables as well as cardio respiratory variables were determined for each subject. Standard Nerve Conduction Techniques using constant measured distances were applied to evaluate common peroneal nerve (motor) in both legs of each individual. Data were analyzed and compared between study and control groups using Man Whitney test setting the significance level ≤ 0.05.

RESULTS

Anthropometric and cardio respiratory variables were not significantly altered between the study and control groups. The Compound muscle action potential (CMAP) latency of common peroneal nerves of both right [(11.29 ± 1.25 vs. 10.03 ± 1.37), < 0.001] and left [(11.28 ± 1.38 vs. 10.05 ± 1.37), < 0.01] legs was found to be significantly prolonged in study group as compared to control group. The Amp-CMAP of common peroneal nerves of both right [(4.57 ± 1.21 vs. 6.22 ± 1.72), < 0.001] and left [(4.31 ± 1.55 vs. 6.25 ± 1.70), < 0.001] legs was found significantly reduced in study group as compared to control group. Similarly, the motor nerve conduction velocity (MNCV) of common peroneal nerves of both right [(43.72 ± 3.25 vs. 47.49 ± 4.17), < 0.001] and left [(42.51 ± 3.82 vs. 46.76 ± 4.51), < 0.001] legs was also found to be significantly reduced in study group in comparison to control group.

CONCLUSION

Operating mechanical sewing machine by paddling chronically and arduously could have attributed to abnormal nerve conduction study parameters due to vibration effect of the machine on right and left common peroneal nerves. The results of present study follow the trend towards presymptomatic or asymptomatic neuropathy similar to subclinical neuropathy.

摘要

背景

尼泊尔大多数从事裁缝职业的人仍在使用机械缝纫机作为裁缝新技术的替代品。左右腿的腓总神经都暴露于机械缝纫机振动和踏板操作所施加的剧烈和慢性压力之下。

方法

该研究纳入了30名健康男性裁缝和30名健康男性个体。为每个受试者测定人体测量学变量以及心肺变量。使用恒定测量距离的标准神经传导技术来评估每个个体双腿的腓总神经（运动）。使用曼-惠特尼检验对研究组和对照组的数据进行分析和比较，设定显著性水平≤0.05。

结果

研究组和对照组之间的人体测量学和心肺变量没有显著变化。与对照组相比，研究组右[（11.29±1.25对10.03±1.37），<0.001]、左[（11.28±1.38对10.05±1.37），<0.01]腿腓总神经的复合肌肉动作电位（CMAP）潜伏期显著延长。与对照组相比，研究组右[（4.57±1.21对6.22±1.72），<0.001]、左[（4.31±1.55对6.25±1.70），<0.001]腿腓总神经的波幅-复合肌肉动作电位（Amp-CMAP）显著降低。同样，与对照组相比，研究组右[（43.72±3.25对47.49±4.17），<0.001]、左[（42.51±3.82对46.76±4.51），<0.001]腿腓总神经的运动神经传导速度（MNCV）也显著降低。
