Can Temperature Have An Effect on Musculoskeletal Complaints?

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.

Warming Up Before Activity

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 […]

Reducing Musculoskeletal Disorders among Airport Baggage Screeners and Handlers

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 […]

Musculoskeletal Disorders and Workplace Factors – A Critical Review of Epidemiologic Evidence for Work-Related Musculoskeletal Disorders of the Neck, Upper Extremity, and Low Back

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

What are Sprains and Strains?

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 […]
