Hi Ann
Could only get this abstract off the Ergonomics website, which is probably
what you have.
The full report can be purchased for $30 from Elsevier Science Direct
www.sciencedirect.com or you may be able to get info from a local
ergonomist - check out the Directory of Registered Members and Fellows 2004
at www.ergonomics.org.uk or there might be a member on this mail list.

Abstract
Sewing machinists suffer from musculoskeletal problems, which have been
attributed to poor working postures as well as to the repetitive hand
and arm movements. Their posture is constrained by both the visual and
the manual aspects of the task, and the design of the sewing machine
and table have a considerable influence on the posture adopted. The
potential for improvement of industrial sewing machines was
investigated in a study of the effects of two design parameters (table
inclination and view of the needle). It was shown that both trunk
posture and head/neck flexion could be improved significantly by
altering these design parameters. Trunk posture was found to be
strongly related to the manual aspects of the task, and could be
improved by altering the working positions for the arm. Head posture
was most influenced by the view of the task/needle and could be
improved by improving the visual condition for the task.
Author Keywords: musculoskeletal stress; sewing machine operators;
