MSDs - or repetitive strain injuries - occur in the muscles, tendons and nerves as a result of continued exposure to repetitive work, awkward postures and other facts.

In an effort to inform people about - and prevent - these injuries, the online tool lets users click on body parts to get information. For each body part, it highlights tasks that may lead to an MSD. It also recommends ways to reduce potential hazards, such as slouching at your desk.

The tool is part of the McGuinty government's broader efforts to prevent workplace injuries.

The government also partners with labour organizations and others to combat MSDs by providing resources to employers and workers. These include a prevention guide, resources manual and toolkits.
