Quantitative Measures of Physical Risk Factors Associated with Work-Related Musculoskeletal Disorders of the Elbow: A Systematic Review.

Background: Work-related musculoskeletal disorders at the elbow are a common health problem, which highly impacts workers' well-being and performance. Besides existing qualitative information, there is a clear lack of quantitative information of physical risk factors associated with specific disorders at the elbow (SDEs).

Objective: To provide evidence-based quantitative measures of physical risk factors associated with SDEs.

Occupational kneeling and squatting: development and validation of an assessment method combining measurements and diaries.

Objectives: As knee-straining postures such as kneeling and squatting are known to be risk factors for knee disorders, there is a need for effective exposure assessment at the workplace. Therefore, the aim of this study was to develop a method to capture knee-straining postures for entire work shifts by combining measurement techniques with the information obtained from diaries, and thus avoiding measuring entire work shifts. This approach was applied to various occupational tasks to obtain an overview of typical exposure values in current specific occupations.

Validity of self-reports of knee-straining activities at work: a field study with 6-month follow-up.

Objectives: To measure short-term and long-term validity of self-reported duration of kneeling and squatting at work and to examine the possibility of differential misclassification due to knee complaints.

Methods: Work-related kneeling and squatting were analysed for 190 male subjects (mean age, 35.0 and SD, 11.
