Thoracic Posture / Movement Analysis Flashcards
When observing the position of the patient’s nose from an anterior view, which anatomical landmark should you use as a reference?
Sternum
How does a patient’s levelness of shoulders / angle of clavicle vary depending on handedness?
Dominant shoulder tends to be lower (more muscle mass)
Clavicle can have more of a downward slope
What is considered a “normal” Carrying Angle?
10-15 degrees
When evaluating a patient’s posture from a lateral view, an imaginary line should be drawn through the following structures:
External Auditory Meatus
AC Joint
Humeral Head
Greater Trochanter
Anterior to Lat Malleolus
Scapular Protraction is associated with which posture abnormality?
Flat Back
What spinal levels are significant to the position of the scapulae? How far should the medial border be from the spine?
Scapula from T2 (superior border) to T7 (inferior border)
3 finger width from spine
Why is the Infraspinatus muscle observable from the back while the Supraspinatus is not?
The Supraspinatus is covered by the UT
Which nerve could be damaged in the case of an observable abnormality in the Infraspinatus muscle?
Suprascapular N.
What is the normal resting position of the arm?
Humerus in a neutral rotated position (1/3 or less of humeral head anterior to the acromion)
Cubital Fossa facing anteriorly
Olecranon facing posteriorly
Hand facing the body
Abnormal Positions of the Humerus
Anterior: Humeral head >1/3 length in front of Acromion (Kyphotic posture / tight pecs)
Abducted: Distal end away from the body
IR: Palm faces posteriorly / cubital fossa faces medially / olecranon faces laterally (tight pecs, Lats, Teres / rib positioning)
Flexed: Distal end in front of Humerus
Extended: Distal end behind Humerus
What postural abnormality is shown in the picture below?
Humerus is positioned anteriorly on both sides (more pronounced on the L)
What postural abnormality is shown in the picture below?
B arms flexed and IR
What postural abnormality is shown in the picture below?
L arm abducted and flexed
Position of the Plumb Line in a “Normal” Posture
Anterior To: Lateral malleolus / knee joint
Through: GT (line slightly posterior to hip joint axis) / bodies of lumbar and cervical vertebrae / GH joint / lobe of ear
Lordotic Posture (Positioning of Body Components)
Head: Forward
Cervical Spine: Increased lordosis
Scapulae: Abducted
Thoracic Spine: Increased kyphosis
Lumbar Spine: Hyperextended (lordosis)
Hips: Flexed
Pelvis: Forward (APT)
Knees: Hyper extended
Ankles: PF
Lordotic Posture (Short and Tight Muscles)
Neck extensors / hip flexors / LB
Lordotic Posture (Lengthened and Weak Muscles)
Neck flexors / upper back / Erector Spinae / HS / possibly abs
Lumbosacral Angle (Lordotic Posture)
Increased
Swayback Posture (Positioning of Body Components)
Head: Forward
Cervical Spine: Upper extended / lower flexed
Scapulae: Winged
Thoracic Spine: Kyphotic upper / normal lower
Lumbar Spine: Flat (lower extended / upper flexed)
Hips: Extended
Pelvis: PPT / anterior shift
Knees: Neutral to hyper extended
Ankles: Neutral
Swayback Posture (Short and Tight Muscles)
HS / IO / LB (ES, QL)
Flat Back Posture (Positioning of Body Components)
Head: Forward
Cervical Spine: Upper extended / lower flexed
Thoracic Spine: Upper flexed / lower flat (hypokyphosis)
Lumbar Spine: Flattened
Hips: Forward and extended
Pelvis: PPT
Knees: Hyper extended
Ankles: Neutral
Swayback Posture (Lengthened and Weak Muscles)
Hip flexors / EOs / upper back extensors / neck flexors
Flat Back Posture (Short and Tight Muscles)
HS / abdominals
Flat Back Posture (Lengthened and Weak Muscles)
Hip flexors
