Understanding knowledge transfer in an ergonomics intervention at a poultry processing plant.

This case study reviews the knowledge transfer (KT) process of implementing a knife sharpening and steeling program into a poultry processing plant via a participatory ergonomics intervention. This ergonomics intervention required stakeholder participation at the company level to move a 'train-the-trainer' program, developed in Québec, Canada, into action on the plant's deboning line. Communications and exchanges with key stakeholders, as well as changes in steeling and production behaviours were recorded.

A biomechanical study in cadavers of cast boots used in the early postoperative period after first metatarsophalangeal joint arthrodesis.

Objectives: To compare the effectiveness of 3 common models of walking boots (Walkabout, Samson Walker and Equalizer Premium Walker) to that of a fibreglass cast in protecting an arthrodesis of the first metatarsophalangeal (MTP) joint in the early postoperative period, we carried out a biomechanical study in cadavers in the bioengineering laboratory at Memorial University of Newfoundland.

Methods: Two cadaver models of a first MTP joint arthrodesis were prepared by placing a strain gauge at the joint. This provided a measure of the bending moment across the fusion site.
