Ergonomic evaluation of computer workers.

Introduction: Information technologies have become indispensable in the office environment with a considerable increase in the use of computers. Musculoskeletal complaints in computer workers have a multifactorial etiology; therefore, an ergonomic investigation should be based on both self-reporting of symptoms and quantifiable observational methods.

Objectives: This study aimed to evaluate ergonomic and biomechanical characteristics of computer workers to identify the presence of symptoms and to assess the existence of a correlation between experts' observational assessment and workers' self-perception.

Assessment of arm, neck and shoulder complaints and scapular static malposition among computer users.

Background: Musculoskeletal complaints of the arm, neck and/or shoulder not attributed to acute trauma or any systemic disorder (CANS) are characterized by symptoms such as pain, numbness and paresthesia which may reach severe and disabling levels and thus significantly interfere with the performance of work and daily living activities. Computer use at work considerably increased in recent years, being attended with a substantial elevation of the prevalence of CANS among individuals who use computers at work.

Objective: To investigate biomechanical and psychosocial risk factors, scapular static imbalance and functional impact on work and daily living activities of upper limb complaints among workers who use computers.
