Area of Science:

  • Digital Pathology
  • Ergonomics
  • Musculoskeletal Health

Background:

  • Musculoskeletal disorders are common among pathologists.
  • The increasing digitization of pathology necessitates evaluating tools used for whole slide image review.

Purpose of the Study:

  • To investigate muscle activity patterns and extent during the use of various input devices for whole slide image revision.
  • To compare the ergonomic impact of different input devices in digital pathology.

Main Methods:

  • A comparative study evaluated 10 input devices using a Fitts' Law based digitized tissue array.
  • Surface electromyography measured electrical activity in seven upper limb muscles of six medical students.

Main Results:

  • Significant differences in overall muscle activity were observed across devices (p<0.001).
  • Devices like Rollermouse™, trackballs, and Ergopointer™ required less muscle activity compared to optical pen mice, Leap Motion™, and touchpads.
  • Touchpads and the EIGIIS trackball showed the highest muscle mobilization.

Conclusions:

  • Input device selection in digital pathology significantly impacts muscle activity and ergonomics.
  • Variability in muscle activity suggests potential for different long-term muscular fatigue patterns.
  • Ergonomic impact should be a key consideration when choosing input devices for digital pathology.
