Brief Summary

This quasi-experimental study was performed in poultry processing industry. The study aimed to evaluate the benefits of ergonomic training for novice and experienced workers. Sociodemographic and occupational questionnaires were evaluated, musculoskeletal complaints and pain intensity, perceived occupational effort, biomechanical exposure and perception in adopting the training. Complaints in the cervical, wrist and lumbar region were reduced with training, but the intensity of pain was only reduced in the wrist region. There was a reduction in the occupational biomechanical exposure from pre-training, to the post-immediate, and from pre-training to after 2 months for both beginners and experienced. The group of novice workers differed from those with the highest biomechanical exposure reduction in the cutting room tasks. All workers were benefited by ergonomic training in the short and medium term.

Conditions

Occupational Exposure

Outcome Measures

Primary Outcomes (3)

• Change from Musculoskeletal Complains at 2 months

  The Nordic Musculoskeletal Questionnaire was used to investigate the presence of musculoskeletal symptoms in the last month with dichotomous responses (yes or no)

  baseline, after two months

• Change from Pain Intensity at 2 months

  The visual analogue pain scale evaluated the intensity of symptoms indicating "absence of pain" (0) on one side and the opposite side "unbearable pain" (10 cm).

  baseline, after two months

• Change from Biomechanical Exposure immediately after the interventional training and after two months

  Analysis of the biomechanical exposure of each segment (cervical, shoulder, forearm, wrist, hand and spine) by by an observational method developed for the study with score (0-19 points).

  baseline, after 1-2 days, after two months

Study Arms (2)

Novices

EXPERIMENTAL

They received ergonomic training after 1-2 days of hiring to do the work in the cutting room, and packaging sectors. They did not have experience in the refrigerator or butchers, so they had the minimum of information about tasks and risks.

Other: Ergonomic Training

Experienced

EXPERIMENTAL

They received the same ergonomic training as the newbies, and should have been hired for more than 6 months in the company. In this period they had already acquired patterns of movement and self-protection to accomplish the tasks.

Other: Ergonomic Training

Interventions

Ergonomic Training OTHER

The ergonomic training consisted of an educational program in Ergonomics with a duration of 60 (sixty) minutes divided into a theoretical exposition and videos of the occupational tasks performed by the workers themselves. Theoretical lecture covered topics such as ergonomics, human anatomy, worker health, prevention measures to minimize the risks of musculoskeletal diseases. A better way of performing the work to protect the musculoskeletal system was demonstrated.

Also known as: Postural and Occupational (tasks) training

Experienced; Novices
