Summary

Mononeuropathy at the wrist affects 10.3% of engineers. Increased computer use and body mass index are associated risk factors for this condition.

Area of Science:

  • Occupational health
  • Neurology
  • Epidemiology

Background:

  • Mononeuropathy at the wrist is a common condition.
  • Engineers using computers are at risk due to prolonged screen time and repetitive motions.

Purpose of the Study:

  • To determine the prevalence of mononeuropathy at the wrist in computer-using engineers.
  • To identify risk factors associated with this condition.

Main Methods:

  • A cross-sectional study involving 202 engineers.
  • Utilized questionnaires and electrophysiological nerve testing.
  • Defined mononeuropathy based on symptoms and abnormal nerve conduction.

Main Results:

  • The prevalence of wrist mononeuropathy was 10.3% (right median), 3.4% (left median), 1.8% (right ulnar), and 2.9% (left ulnar).
  • Positive associations were found with body mass index, computer use duration, and antihypertensive medication.
  • Negative associations were observed with typing speed, driving hours, and total break time.

Conclusions:

  • Mononeuropathies at the wrist are prevalent in computer-using engineers.
  • Risk factors include prolonged computer use, higher body mass index, and certain medications.
