|
trunk flexion |
rectus abdominus (synergistic muscles: internal oblique, external oblique) |
|
|
trunk extension |
erector spinae (longissimus, iliocostalis, spinalis) synergistic: latissimus dorsi |
|
|
lateral flexion muscle |
quadratus lumborum (synergistic muscles: erector spinae, latissimus dorsi) |
|
|
left rotation |
left internal oblique, right external oblique helper muscle: right erector spinae |
|
|
abdominal compression (to raise internal pressure?) |
transversus abdominus |
|
|
what happens with insufficient trunk control of trunk flexion? (rectus abdominus) |
-trunk moves posteriorly (posterior pelvic tilt) -shoulders flex and elevate to fight against gravity, in attempt to raise trunk -extension of unaffected UE and LE to push against surface |
|
|
what other movements are associated with weak trunk extension (erector spinae)? |
-when arm is reaching: shoulder elevation of reaching arm, lateral flexion of opposite side -upper and lower trunk flexion with change in scapular position -change in head position for vision and swallowing concerns -unopposed extensors - head closer to sacrum |
|
|
what does lack of coordination of trunk flexors and extensor muscles lead to? |
-inability to shift weight over pelvis, collapsing laterally -overuse of shoulder elevation and lateral flexion -increased trunk flexion or extension |
|
|
loss (on one side) of abdominal oblique muscles lead to these movements |
-overuse of opposite side for transitional movements |
|
|
insufficient anterior/posterior pelvic tilts lead to these movements: |
-elevated shoulders with trunk flexion -head/neck hyperextension for visual correction |
|
|
insufficient lateral weight shifts lead to these movements |
using upper trunk to flex, movement achieved through anterior posterior plane |
|
|
rotational and diagonal shift difficulties (oblique muscles) |
-difficulty with transitional movements (require shifting) -difficulty placing upper extremity in function |
|
|
what muscle issues cause posterior pelvic tilt/thoracic spine flexion? |
-weak trunk extensors (to straighten the back) -contracture in hamstrings -abdominal weaknesses (to bring bottom trunk to 90) |
|
|
what causes lateral trunk flexion (muscle changes)? |
-inactive shoulder elevators (shoulder drops) -increased activity of scapular depressors -shortening of lateral flexors -perceptual dysfunction - fear of shifting weight to affected side |
