8/21 - anatomical terms for pelvic, scapular, clavicular and thumb movements

what is anterior pelvic tilt?

When the ASIS is anterior to the pubic bone

what is the clinical significance of anterior pelvic tilt?

-increased lumbar lordosis
-low back pain
-weak abs and tight hip flexors

• changes the orientation of hip and sacroiliac joints

What is posterior pelvic tilt?

When the ASIS is posterior to the pubic bone

what is the clinical significance of posterior pelvic tilt?

-decreased lumbar curved
-low back pain or disc compression

• short or stiff hamstrings
• may impact posture or spinal alignment

What is lateral pelvic tilt?

when the crest of the ilium is higher on one side than the other, creating an asymmetry in the pelvis position

what are clinical significances of lateral pelvic tilt?

-leg length discrepancy or muscle imbalance

• scoliosis
  -asymmetrical loading of joints

what is scapular adduction?

when the scapula translates medially along the rib cage toward the vertebral column

this is also called retraction

what is scapular abduction?

when the scapula translates laterally along the rib cage away from the vertebral column

also called protraction

what is scapular upward (lateral) rotation?

a movement of the scapula where the inferior angle moves laterally and the glenoid fossa rotates to face cranially

what is scapular downward (medial) rotation

a movement of the scapula where the inferior angle moves medially and the glenoid fossa rotates to face caudally

what is scapular elevation?

when the scapula translates along the ribcage in an upward direction

what is scapular depression?

Downward (inferior) motion of the scapula.

what is anterior tilt of the scapula?

what is posterior tilt of the scapula?

what is internal rotation of the scapula?

what is external rotation of the scapula?

what is scapular winging?

posterior lateral movement of the vertebral border of the scapula in the transverse plane

what is clavicular elevation?

what is clavicular depression?

what is clavicular protraction?

what is clavicular retraction?

what is clavicular posterior longitudinal rotation?

what is thumb opposition?

movement of thumb across palmar aspect to oppose any or all of the phalanges

what is thumb flexion?

movement of the thumb medially across the palm in frontal plane

what is thumb extension?

thumb moves away from midline

what is thumb abduction?

movement of the thumb away from the palm in the sagittal plane

what is thumb adduction?

movement of the thumb toward the palm in the sagittal plane
