Pattern Overload
When a segment of the body is repeatedly moved or chronically held in the same way, leading to a state of muscle overactivity.
Kyphosis
Natural curvature of the thoracic spine toward the back of the body.
Lordosis
Natural curvature of the cervical spine toward the front of the body.
Lordotic Posture
Excessive lumbar lordosis and an anterior pelvic tilt. May also assume other compensatory positions such as a lateral lumbar shift, lateral leg rotation, and knees slightly flexed or hyperextended.
Flat-Back Posture
Forward head, hyperextended cervical spine, excessive upper thoracic kyphosis (rounding), reduced lower thoracic kyphosis (flattening), and rounded shoulders. May also have reduced lumbar lordosis, a posteriorly tilted pelvis, extended hip, extended knees, and slightly plantar flexed ankles.
Sway-Back Posture
Forward head, extended cervical spine, and excessive thoracic kyphosis (posterior displacement); may have reduced lumbar lordosis (flattening), a posteriorly tilted pelvis, extended hips, hyperextended knees, and neutral ankles.
Kyphosis-Lordosis Posture
Forward head, excessive thoracic kyphosis, rounded and elevated shoulders; excessive lumbar lordosis, lateral lumbar shift, anterior pelvic tilt, flexed hips, knees hyperextended or flexed, and ankle plantar flexion.
Common Upper Body Overactive (Shortened) Muscles
Cervical extensors, latissimus dorsi, levator scapulae, pectorals, scalenes, sternocleidomastoid, upper trapezius.
Common Upper Body Underactive (Lengthened) Muscles
Deep cervical flexors, middle and lower trapezius, rhomboids, serratus anterior.
Common Lower Body Overactive Muscles
Gastrocnemius, hamstrings, hip adductors, piriformis, psoas, quadratus lumborum, rectus femoris, soleus, tensor fascia latae.
Lower Crossed Syndrome
Excessive lumbar lordosis and an anterior pelvic tilt; may also include a lateral lumbar shift, knees slightly flexed or hyperextended, and feet plantar flexed.
Upper Crossed Syndrome
Forward head, hyperextended cervical spine, and rounded shoulders; sometimes includes excessive thoracic kyphosis, elevated shoulders, rotated or abducted shoulders, and winging scapulae.
Layered Cross Syndrome
May present with both Upper and Lower Crossed Syndromes.
Pes Planus Distortion Syndrome
Excessive flat feet, knee flexion, hip and knee internal rotation, knee valgus, and an anterior pelvic tilt.
