- Training in the proper use of earplugs: An objective evaluation(2020) TAKADA, Mirian Missae; ROCHA, Clayton Henrique; NEVES-LOBO, Ivone Ferreira; MOREIRA, Renata Rodrigues; SAMELLI, Alessandra GiannellaBACKGROUND: Discrepancies between attenuation obtained in the laboratory and the field are caused by several factors associated with hearing protection devices (HPDs). The effects of some factors can be minimized with proper training provided to HPD users. OBJECTIVE: To evaluate the effectiveness of an educational intervention for improving the correct use of earplugs as HPDs in workers exposed to occupational noise by using the F-MIRE method and by comparing pre- and post-training attenuation values and pass/fail rates. METHODOLOGY: The personal attenuation ratings (PARs) of two types of earplugs were obtained (140 individuals) using E-A-Rfit (TM) equipment. Each HPD was evaluated under two scenarios: first after the user only read the packaging instructions, and then after the user read guidelines and participated in a training program. The results obtained were automatically classified by the software as ""Approved"" or ""Failed"". RESULTS: There was a significant post-training increase in the binaural PAR values for both HPDs. The percentages of passes pre- and post-training showed that training users in the proper fit of the HPD was effective; both types had statistically significant differences. CONCLUSION: This study found a statistically significant increase in PARs and the number of workers passing evaluations after HPD fit training, demonstrating the effectiveness of this educational intervention.
- Training on hearing protector insertion improves noise attenuation(2015) SAMELLI, Alessandra Giannella; ROCHA, Clayton Henrique; THEODÓSIO, Patrícia; MOREIRA, Renata Rodrigues; NEVES-LOBO, Ivone FerreiraABSTRACT Purpose: To determine the efficacy of hearing protector insertion by comparing attenuation values measured by objective (MIRE) and subjective (REAT) methods in groups with and without training. Methods: The study included 80 male subjects assigned to experimental (with training) and control (without training) groups. The following procedures were performed: occupational history, objective and subjective assessment of hearing protectors. Only subjects in the experimental group received training and guidance on proper hearing protector insertion. Results: Attenuation values were significantly higher in the experimental group than in the control group at all frequencies (500, 1000, 2000, and 4000 Hz) investigated through the objective (MIRE) and subjective (REAT) methods. In addition, attenuation values in the control group were lower than those provided by the hearing protector manufacturer. Conclusion: Both objective and subjective attenuation tests demonstrated the efficacy of training on insertion of hearing protectors because the group that received training on proper hearing protection insertion exhibited higher attenuation values than the untrained group.
- Effects of a vestibular rehabilitation program on workers in the working environment: a pilot study(2018) LONGO, Isadora Altero; NUNES, Ariane Diane Morais; ROCHA, Clayton Henrique; BRANCO, Fabiana Mara; MOREIRA, Renata Rodrigues; NEVES-LOBO, Ivone Ferreira; CASAROTTO, Raquel Aparecida; SAMELLI, Alessandra GiannellaABSTRACT Objective: to verify the effect of a vestibular rehabilitation program on workers with dizziness from the Division of Nutrition and Dietetics at a University Hospital. Methods: a total of 13 employees between 42 and 65 years of age participated, of whom, 1 was male, and 12, females. They were evaluated before and after the vestibular rehabilitation program using the Dizziness Handicap Inventory, Work Ability Index and Visual Analog Scale. The program was conducted in groups at the workplace. Statistical analysis was performed using the analysis of variance test for paired factors and the chi-square test. Results: in the pre- and post-vestibular rehabilitation comparison, significant differences were found in the Dizziness Handicap Inventory and Visual Analogue Scale scores. In the qualitative analysis of the Work Ability Index, an increase was observed in the number of workers who considered their ability to work to have improved. Conclusion: vestibular rehabilitation conducted in groups and in the working environment was effective in improving dizziness complaint in workers at the Division of Nutrition and Dietetics. It is believed that the positive experience of this program may be extended to other areas.
