Resumen
Lumbar pain syndrome is considered by the American Conference of Industrial
Hygienists (ACGIH) as a chronic disorder in muscles, tendons or nerves caused by
repetitive stress, quick movements, forces of high magnitude, contact stress,
extreme postures, vibration and / or low temperatures, all related to the job.
At least 50% of the economically active population at some point in their lives be
pain in the loins. It is important to mention that the experts agree that one of the
most common causes of back pain in the workplace, it is for cargo handling, which
by its own property, can be generated from lumbar back injury.
For this reason was to examine the risk characteristics of the job of packer, who
were favoring the presence of low back pain the packing extruded platform in order
to establish the following points: 1) evaluate the factors risk in the position of
"packer", 2) ergonomic evaluation in the workplace, 3) establish the relationship
between risk factors identified and the presence of low back pain in workers under
study and 4) development of a proposal prevention and control of Lumbar Pain
Syndrome in the packers.
To obtain these results we applied different evaluation methodologies, as they
were for ergonomic evaluation: OWAS method, and anthropometric evaluation
RULA (Mujica, I.). For the detection of risks, apply the methodology of Risk
Assessment Toxicology, United States Environmental Protection Agency's (EPA)
adapted.
The results showed that the charge represents a high risk in the evaluation of the
position, and the presence of repetitive motion, lifting upper limb above your man's
plans, as well as rotary motion lumbar region. This syndrome generator back pain,
study in the analysis of anthropometry, BMI (Body Mass Index) greater than 25
represents a risk factor for the presence of compensatory hyperlordosis way,
producing a generation or trigger mechanism of pain in the loins. (Lustgarten,
2010).
Therefore, the results suggest that exposure to these risks ergonomic and
anthropometric variables are some of the causes lumbar pain syndrome, however
there are always other possibilities ruled out extra work not included in the study
