👁 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 stability
Here’s a natural clinical example:
“The patient demonstrated improved trunk stability during sitting balance exercises.”
