One of the simplest things employees can do to help prevent injuries is also one of the most important. That one thing is workplace ergonomics. Workplace ergonomics in used in most contexts as it relates to the position of a person sitting at their desk. While this is true, it does not stop in the office. Ergonomics is a science that deals with the design and arrangement of the things people use at work to make the work easier and/or safer. Read more

To date, there is little information to assist people interested in purchasing alternative keyboards. While the scientific evidence about whether alternative keyboards prevent musculoskeletal disorders is inconclusive at this time, this document provides basic information about common alternative keyboard designs and their effects on work posture.

European researchers studied the effects of environmental and psychosocial factors and their relationship with musculoskeletal disorders (MSD). The survey was conducted among hospital workers in the UK and they looked at responses relating MSDs to temperature, anxiety, depression, light and noise, and job demand. The most interesting finding from the study was that MSDs of the upper extremity were strongly related to job strain and temperature.

This document is a joint effort between NIOSH and the Canadian Centre of Research Expertise for the Prevention of Musculoskeletal Disorders (CRE-MSD).

The purpose of this document is to help practitioners assess working posture for the prevention and control of occupational musculoskeletal disorders (MSDs). Read more

Warming up before activity is important, especially for those performing strenuous or repetitive jobs.

We have all heard about stretching before or after activity, or as a way to break up repetitive tasks, but should we warm-up? Warming up has been shown to be effective in helping reduce overexertion which can cause sprains and strains of the muscles, tendons and ligaments. Warming up does this by: Read more

Baggage screeners and handlers at airports are exposed to manual baggage lifting and handling that are associated with work-related musculoskeletal disorders (WMSDs). The National Institute for Occupational Safety and Health (NIOSH) evaluated two mechanical lift aids to determine if they could reduce the risk of WMSDs. The two mechanical lift aids reduced some physical WMSD risk factors such as hand loading and spinal compression force.

The World Health Organization (WHO) reports that more than half of the adult population will experience a headache during the year and that the majority of headaches are under-recognized and under-treated.

Musculoskeletal disorders (MSDs) were recognized as having occupational etiologic factors as early as the beginning of the 18th century. However, it was not until the 1970’s that occupational factors were examined using epidemiologic methods, and the work-relatedness of these conditions began appearing regularly in the international scientific literature. Since then Read more

Sprains and strains are injuries to tissue typically attributed to overexertion or traumatic type injuries. The names differ due to the type of tissue involved in the injury.

A sprain is an injury involving a ligament. Ligaments are tough connective tissue bands that connect bone to bone. These tissues hold the joints together throughout the body. The most common, and the one people are most familiar with is an ankle sprain.

A strain is an injury involving the muscle or tendon. The muscle is the contractile portion responsible for creating motion. The tendon is the terminal fibrous component of the muscle, which attaches it to the bone. Most commonly and familiar is a strain of the low back. Read more
