Hypothesis

The study aims to determine the prevalence and predictors of musculoskeletal symptoms in the upper extremities and neck at VDT workstations.

Conclusion

Preventive measures at VDT workstations should focus on neck and shoulder symptoms to reduce musculoskeletal issues.

Supporting Evidence

  • 55% of employees reported neck symptoms in the past year.
  • 38% reported shoulder symptoms.
  • 21% reported hand/wrist symptoms.
  • 15% reported elbow/lower arm symptoms.
  • Typing for more than 6 hours a day significantly increased neck symptoms.

Takeaway

Many people who work at computers have pain in their neck and shoulders, and taking breaks can help.

Methodology

A cross-sectional study using standardized questionnaires and physical examinations to assess symptoms and workstation conditions.

Potential Biases

Self-reported symptoms may lead to over- or underestimation of prevalence.

Limitations

The study's cross-sectional design limits causal inferences, and self-reported data may introduce bias.

Participant Demographics

65% male, mean age 39.9 years, with a mean daily VDT use of 5.1 hours.

Statistical Information

P-Value

p<0.001 for gender effects on symptoms.

Confidence Interval

95% CI for neck symptoms: 61.2, 70.7

Statistical Significance

p<0.05
