By means of a hand ergometric graph the following parameters were examined in workers exposed to vibration: total power of the right hand (Pc) and the power obtained in successive 5-second intervals (P(i)). Total test time (tc) was measured directly, the fast increasing time of fatigue (tn) and the work performed during those times (W). The group exposed to local vibration consisted of 40 workers on iron-works and the control group 50 non-exposed workers of the same iron-works. A significantly shorter fast increasing time of fatigue and the decrease of the total power of the hand were found in the study group in comparison with controls. Moreover, the P(i) power was significantly lower in the exposed group from the 30th second of the test.
通过手部测力计图表，对接触振动的工人的以下参数进行了检测：右手的总功率（Pc）以及连续5秒间隔内获得的功率（P(i)）。直接测量总测试时间（tc）、疲劳快速增加时间（tn）以及在这些时间段内完成的工作量（W）。接触局部振动的组由40名炼铁厂工人组成，对照组为同一炼铁厂的50名未接触振动的工人。与对照组相比，研究组的疲劳快速增加时间明显缩短，手部总功率降低。此外，在测试的第30秒后，暴露组的P(i)功率显著降低。
