👁 What Does “Trunk” Mean?

The trunk refers to the central part of the human body, excluding the head and limbs.

It includes the thorax, abdomen, and pelvis — essentially everything between the neck and the hips.

The word comes from Latin truncus, meaning “the main stem of a tree.”

In modern medicine, trunk is used as a neutral anatomical term, particularly in physiotherapy, rehabilitation, orthopedics, and nursing documentation.


🔍 Clinical Usage

In clinical settings, trunk is used to describe movement, muscle groups, posture, injuries, and physical assessment findings. You’ll see it in:

  • physiotherapy and occupational therapy notes
  • nursing assessments
  • rehabilitation plans
  • discharge summaries
  • orthopedic and neurology documentation

Healthcare professionals use the term when discussing core stability, posture, balance, and mobility, because the trunk plays a central role in all of these functions.

Common collocations include:

  • trunk rotation
  • trunk flexion / extension
  • trunk muscles
  • trunk control
  • trunk stability

Here’s a natural clinical example:

“The patient demonstrated improved trunk stability during sitting balance exercises.”
→ Meaning: The patient could maintain posture more effectively while seated.
