he aim of the present study is to assess the impact of working

postures in computer work stations on musculoskeletal

disorders (WMSDs) among office workers in an Algerian tertiary

sector. To investigate the relationship between working postures

adopted by office workers andWMSDs, a sample of (20) male and

female computer users participated in the study. The study was

conducted into two steps: during the first step each participant

was interviewed in order to determine the following parameters:

(1) work time span to end work tasks, (2) rest poses, and (3)

the preferred time to work on computer. While, the second step

consisted of the application of the Rapid Upper Limb Assessment

(RULA) method to evaluate different working postures adopted by

members of the sample. A sample of 20 minutes of continuous

observation was recorded with each participant. The results of

the study revealed that: (1) working on the computer for a long

time while maintaining inappropriate postures, contributed to the

emergence of musculoskeletal disorders (neck, shoulders, low

back pain), (2) office workers of the study are exposed to high

WMSDs risk, which is due to inappropriate workstations layout

that impose bending and twisting postures while working, as a

result of incompatibility of office furniture and equipment with

the anthropometric body dimensions of workers. This situation

requires in-depth study, as well as, ergonomic intervention and

improvement in the near future. A series of suggestions, are

put forward, including the reorganization and layout of office

equipment according to the ergonomic norms, taking into account

a visual field of 15°to 30° angle.
