Crossed Syndrome - Movement Exam 1

what is necessary to ensure proper activity of the skeletal muscles

exposure of human body to gravity forces and routine stability functions

what happens when the human body is not stimulated routinely to use these stabilizing muscles?

their stabilizing function is disturbed by hypoactivity reaction resulting in weakness and atrophy

when are muscle imbalances considered pathological?

when a muscle balance impairs function

what leads to joint dysfunction?

balanced muscular coactivation is lost

what muscles are characteristically tight with upper crossed syndrome?

upper trap, levator scapula, pec major and minor

what muscles are characteristically weak with upper crossed syndrome?

deep cervical neck flexors and middle/lower trap

What other muscles are commonly facilitated/overactive with upper crossed syndrome

anterior delt, SCM, subscapularis, lat, teres major, scalenes, rectus capitis

Which joint dysfunctions commonly arise from the pattern of muscle imbalance seen with upper crossed syndrome

Sternoclavicular joint, acromioclavicular joint, scapulothoracic joint, glenohumeral joint, costovertebral joints, cervical/thoracic facet joints, C-T junction, OA joint

What are the characteristic postural imbalances seen with upper crossed syndrome?

Forward head posture, increase cervical lordosis and thoracic kyphosis, elevated/protracted shoulder, rotation/abduction and winging of scapula

what muscles are characteristically tight with lower crossed syndrome?

thoracolumbar extensors and hip flexors

what muscles are characteristically weak with lower crossed syndrome?

core and gluetes

What other muscles are commonly facilitated/overactive with lower crossed?

Erector spinae, multifidi, QL, lat, peroneals, IT band/TFL, adductor, iliacus, psoas, lateral hamstring, lateral gastroc, soleus

Which joint dysfunction commonly arise from the pattern of muscle imbalance seen with lower crossed syndrome?

1st MTP joint, subtalar joint, talocrural joint, prox. tib/fib joint, femoroacetabular joint, SI joint, lumbar facets

What are the characteristic postural imbalances seen with lower crossed syndrome?

Thoracic hyperkyphosis, lumbar hyperlordosis, anterior pelvic tilt, slight hip flexion, slight knee flexion
