Understanding working postures is crucial for musculoskeletal health. This review highlights the link between posture and injuries, emphasizing the need for systematic data collection to prevent disorders.

Area of Science:

Ergonomics
Occupational Health
Musculoskeletal Disorders

Background:

Working postures are frequently discussed in ergonomics literature.
Specific scientific literature on working posture itself is surprisingly limited.
Existing knowledge on the topic remains elusive.

Purpose of the Study:

To review the existing scientific literature on working postures.
To explore the relationship between working postures and musculoskeletal health.
To identify methods for measuring working postures.

Main Methods:

Literature search of English-language papers before March 2003.
Databases searched: PubMed, Scirus, and Science Direct.
Inclusion criteria: "working postures" in title, abstract, or keywords.

Main Results:

Evidence supports a relationship between working postures and musculoskeletal health.
Theories of overexertion, differential fatigue, and cumulative load explain injury precipitation.
Common measurement tools include goniometers, inclinometers, and photographic/video techniques.

Conclusions:

A systematic approach to collecting and analyzing working posture data is needed.
Improved understanding can enhance the control and rehabilitation of work-related musculoskeletal disorders.
Further research is essential for a deeper understanding of posture-related health issues.
