Flashcards in Screening and Symmetry Deck (18):

What does a screening test evaluate?

1. early disease or risk factors for disease in large numbers of appearing healthy individuals


What does a diagnostic test evaluate?

1. presence or absence of disease as a basis for Tx decisions


What type of screening features fall under palpatory?

1. tissue texture changes

2. asymmetry

3. restrictions

4. tenderness


What are some visual screening techniques?

1. gait 2. landmark 3. posture 4. range of motion


Where are the lordotic curves located in human spines?

1. cervical 2. lumbar 3. appears convex if viewed from anterior


Where is the kyphotic curvature of the spine?

1. thoracic 2. sacral (not necessarily viewable)


Describe side bending.

1. rotation occurring in coronal plane about the anterior-posterior transverse axis


Describe translation.

1. Occurs in a coronal plan with shifted center of mass. body compensates by side bending in order to maintain original center of mass


What is Fryette's third Law?

1. initiating motion of a vertebral segment in any plane of motion will modify the movement of that segment in other planes of motion


What is the Fryette's first law?

1. when thoracic and lumbar spine are in a neutral position, the coupled motions of side-bending and rotation for a group of vertebrae are such that side-bending and rotation occur in opposite directions


What is Fryette's second law?

1. When thoracic and lumbar spine is sufficiently forward or backward bent, the coupled motions of side-bending and rotation in a single vertebral unit occur in the same direction.


What is TART?

1. Tissue texture changes 2. Asymmetry 3. Restriction 4. Tenderness


What are the stages of teh Stance phase of gait?

  1. heelstrike
  2. footflat
  3. midstance
  4. push-off


What are the stages of gait with respect to swing phase?

  1. acceleration
  2. midswing
  3. deceleration


Describe the lateral landmarks to evaluate when watching for posture position.

  1. external auditory canal
  2. head of humerus
  3. body of LV3
  4. anterior 1/3 of the sacral base
  5. greater trochanter (femoral head)
  6. epicondyle of knee
  7. lateral malleolus


What is sidebending?

  1. Rotation in the coronal plane about an A-P axis.


What is translation?

  1. The act of moving a vertebral body laterally within the coronal plane and inducing side bending (indirectly) opposite the direction of translation.
  2. Translation shifts COM, and body sidebends to re-gain the initial COM.


What is Dr. Stiles Screening test for AGR?

  1. induces extension, sidebending and rotation (same side) with translation to screen for any areas of spine that may have somatic dysfunction.
  2. able to use from occiput to sacrum
  3. utilizes thumb and thenar eminance
