Trunk shift
What it usually means, what is likely tight and weak, and a routine that helps. Also called upper body leans to one side, lateral trunk shift.
In short
The upper body sits shifted over one hip at rest.
Why it matters
When the upper body sits off center over the hips, the spine works harder on one side to keep you upright.
Usually tight
- · Quadratus lumborum (shift side)
- · Obliques
Usually weak
- · Gluteus medius (opposite side)
- · Obliques (opposite side)
Other things that can cause it
- · Protective shift from back pain
- · Leg length difference
A corrective routine for trunk shift
Done in this order: calm what is tight, lengthen it, then strengthen what should be doing more. Daily for 3 to 6 weeks is a good start.
Trigger point
Static stretch
Strengthen
Everyday habit
Notice which side you lean on when standing or in the car, and set yourself back to center a few times a day.
How long it takes
Often improves in 4 to 8 weeks, with steady work. Re-check every 2 to 4 weeks.
How Kentro checks it
It shows up in the stand tall, facing part of the scan: face the camera, feet hip width, arms relaxed at your sides. Kentro measures each side separately, so you see which side it is and whether it is improving between scans.
When to see a professional
See a doctor or physical therapist if you have pain that is sharp, getting worse or lasts more than a couple of weeks, numbness, tingling or weakness, pain after a fall or injury, or pain at night. This guide is general education for healthy adults, not a diagnosis or treatment plan.
