Title Evaluation of low back pain risks in a beef skinning operation
Bibliographic information 2000, Vol.6, No.3, p.347-361. Illus. 23 ref.
Abstract Low back pain risks in a beef skinning workstation were evaluated. The increases in compressive forces at the lower back (L5/S1) between normal and severe, and between normal and very severe bent back postures were 387N or 28% and 616N or 45%, respectively. The high spine load coupled with high level of repetition can give rise to fatigue failure in the spine structural members. Non-neutral back posture for a large portion of the total work time can be a low back pain risk factor. Videotape analysis showed that the times involved during the task performance for the bent back (more than 25░) and severe bent back (more than 45░) were 48.4 and 33.5% of the total cycle time, respectively. The upper limit from OWAS (Ovako Working Posture Analysis System) for bent back posture is 30% of the total cycle time. The bent and twisted back posture (both more than 25░) time was 10.4 % compared to OWAS limit of 5%. This indicated that actions are needed to alleviate the risk of low back pain, including ergonomic redesign of the workstation.
