Real-Time Measurement of Postural Stability of Locomotive Drivers

The postural stability and fatigue degree of locomotive drivers are measured and evaluated. Fifty locomotive drivers are subject to the measurement with stabilometer and computer system in case of pre-work, and work after 2 h, 3 h and 4 h respectively. Once the locomotive drivers in sitting posture are overfatigued with work, they can be timely warned by the monitoring system. Experimental results show that the locomotive drivers’postural unbalance are quite different between the two conditions: pre-work andwork after 3 h (p<0. 05).
