Prolonged sitting in video display terminal (VDT) use is linked to increased thoracic hyperkyphosis, a spinal condition. This study suggests ergonomic interventions for VDT workers to prevent posture-related issues.

Area of Science:

  • Occupational Health
  • Biomechanics
  • Spinal Anatomy

Context:

  • The link between prolonged sitting and spinal issues like intervertebral disc degeneration is known.
  • However, the relationship between sitting posture and thoracic hyperkyphosis remains under-researched.
  • Video display terminal (VDT) use necessitates prolonged sitting, making it a relevant focus for posture-related research.

Purpose:

  • To investigate the association between prolonged video display terminal (VDT) use and the development of thoracic hyperkyphosis.
  • To compare the prevalence of thoracic hyperkyphosis in VDT workers versus a control group of telephone line maintenance workers.

Summary:

  • This study examined 63 VDT workers and 71 control subjects, assessing posture through clinical and radiographic examinations.

  • VDT users reported higher rates of rachialgia (back pain) and showed a higher prevalence of thoracic hyperkyphosis compared to the control group.
  • Thoracic hyperkyphosis was significantly more frequent in the dorsolumbar region for VDT users (p<0.05) and associated with age in this group.

    • Impact:

    • Preliminary findings suggest prolonged, fixed sitting postures, typical of VDT work, may contribute to thoracic hyperkyphosis.
    • Age and constitutional factors may also play a role in hyperkyphosis development.
    • The study highlights the need for ergonomic training and preventive measures for VDT users to mitigate posture-related spinal changes.
