Abstract(s)
Occupational exposure to whole body vibrations (WBV) has been identified as a risk factor for the development of low back injuries. Besides others negative health effects, WBV can cause proprioceptive deficits. Thus, the aim of this study was evaluate the impact of the WBV on trunk proprioception of earthmoving machines operators in an extractive industry. The study included twelve healthy subjects, seven experienced operators of earthmoving machinery and five recruited students from the university. Two experimental sessions at the beginning and at the end of the week were performed and trunk position sense absolute errors were assessed for all participants with the active movement reproduction test using a high speed camera (Casio EX-FC 100), for subsequent motion analysis with Kinovea 0.8.24 software. Data analysis demonstrated that the exposed group had higher absolute errors at the beginning and at the end of the week than non exposed group. These results suggest that vibration can alter sensory messages of the skin and muscles receptors and, consequently, change the sensation of the individual position. The implementation of postural reeducation strategies for workers exposed of WBV, can reduce the negative effects on proprioceptive ability.
