Q

Post-stroke issue meeting glenohum stabil/mobil

A

Inferior Subluxation: take up part of hemaperatic arm to maintain shoulder joint ex: sling/pocket

Anterior subluxation: abducts more, sag and lengthened on hemaparetic side, pull arm across body to add glenohum

Q

Post-stroke initiating with scapular elevation

A

NEVER a normal reach pattern-shows compensating

don’t meet obj of scapular stability/mobility
Predisposes them to move with flexor synergy

Work with patients in scap stabilized position to get shoulder flexion/elbow extension

Q

Arm elevation

Phases

A

Elevation: dependant on position of arm to full elevation
Lowering: full elevation to dependant position of arm

Q

OBJ:

Normal glenohum rythm

A

2:1 ration
Maintains GHJ stability when arm overhead
Maintains normal length-tension of rotator cuff
Minimizes subacromial impingment

Q

OBJ:

Glenohum stability and mobility

A

Stability: via compression
rotator cuff stabilizes

Mobility: via force couple action
Supraspinatus helps spin clockwise in line of pull and rotates down; counterbalances upward pull of delt

Q

OBJ:

Scapular stability and mobility

A

Up/Mid/Lower trap, serratus, delt all work together to allow functional movement with upward rotation

Weakness: lose stability

ex: scapular winging if serratus weak
ex: weak lower trap- translates upward

Q

OBJ:

Trunk stability

A

As trunk goes scapula goes with it

One leg tasks: throwing
palvis stability becomes critical, can compensate with trunk

Changing orientation of arm to aim changes torque at shoulder and elbow

Q

Possible compensatory patterns of arm elevation

A

Shrug using upper trap- cuff weakness, lacks inf glid (tight caps), gives pseudo abduction

Trunk lean: further pseudo abd/elevation

Elbow flexion: shortens lever arm if weakness

Overuse levator scap: if lack stability, gives 30 degrees of abd

Q

MOST COMMON compensatory patterns

A

Scapular elevation: induces pseudo shoulder abduction

Lateral trunk lean: induces pseudo shoulder abduction

Elbow flexion: reduces gravitational lever arm
