Posture Dictionary
Plain-language definitions of the postural terms you are most likely to meet — in a clinic, in a scan report, or in something you read at two in the morning. Each entry links to a full explanation of what causes it and what changes it.
Head and neck
Head and neck
- Forward Head Posture — Head sits ahead of the shoulders instead of stacked over them.
- Tech Neck — Forward head posture caused by sustained downward tilt at phones and laptops.
- Military Neck — The neck loses its natural inward curve and sits unusually straight.
- Cervical Kyphosis — The neck curve flattens or reverses into an outward curve.
- Neck Hump — A rounded prominence where the neck meets the upper back.
Upper back and shoulders
Upper back and shoulders
- Kyphosis — The natural outward curve of the upper back — and the deviation when it becomes excessive.
- Hyperkyphosis — An excessive outward curve of the upper back, producing a rounded look.
- Hunchback — Everyday term for a visibly rounded, stooped upper back.
- Rounded Shoulders — Shoulders sit forward of the midline with a tight chest and rounded upper back.
- Winged Scapula — A shoulder blade that lifts away from the ribcage instead of lying flat.
- Uneven Shoulders — One shoulder sits higher or further forward, usually from rotation lower down.
Spine and curvature
Spine and curvature
- Scoliosis — A sideways curvature of the spine, typically with vertebral rotation.
- Kyphoscoliosis — Excessive upper-back rounding combined with sideways spinal curvature.
- Lordosis — The natural inward curve at the neck and lower back.
- Lumbar Lordosis — The inward curve of the lower back — and what happens when it is lost or excessive.
- Hyperlordosis — An excessive inward curve of the lower back, often with a forward-tilted pelvis.
- Flat Back — The lower back loses its inward curve and the pelvis tilts backward.
- Sway Back — The hips sit forward of the trunk while the upper body leans back.
- Rib Flare — The lower front ribs sit lifted and angled outward, often with an arched lower back.
Pelvis and hips
Pelvis and hips
- Pelvic Tilt — The pelvis rotates away from neutral, changing alignment above and below it.
- Anterior Pelvic Tilt — The pelvis rotates forward and down, increasing the arch in the lower back.
- Posterior Pelvic Tilt — The pelvis rotates backward, flattening the lower back and tucking the tailbone.
- Lateral Pelvic Tilt — One side of the pelvis sits higher, functionally shortening one leg.
- Pelvic rotation — One side of the pelvis turns further forward, twisting the trunk.
- Asymmetrical Pelvis — The two halves of the pelvis sit in different positions.
- Uneven Hips — One hip sits higher — usually muscular, not an actual bone-length difference.
Legs, knees and feet
Legs, knees and feet
- Knock Knees — Knees angle inward while the ankles stay apart, usually from hip rotation.
- Bow Legs — Knees stay apart while the ankles touch, giving the legs an outward curve.
- Tibial Torsion — The shinbone rotates along its axis, turning the foot in or out below the knee.
- Hyperextended Knee — The knee pushes back past straight when standing, locking the joint.
- Duck Feet — One or both feet turn outward when standing and walking. Usually starts at the hip.
- Pronation — The inward roll of the foot and flattening of the arch through the step.
General
General
- Core — The trunk muscles that stabilize the spine and pelvis and transfer force.

A definition is not a diagnosis
Recognizing the name for what you see in the mirror is a start, but the useful question is which pattern is driving the others. That is what an assessment answers — thirty minutes, free, in clinic or on Zoom.
