Lecture 7: Trunk Control Flashcards
Why do we examine trunk control?
often overlooked, diffucult to study bc of subtle motions
Why is the trunk so critical to function?
creates stability and motion of center of mass
What are major trunk extensors?
longissimus thoracis, illiocostalis, spinalis
What are major trunk flexors?
Rectus ab.
What are trunk rotators?
internal and external obliques
What are lateral flexors of trunk?
ipsilateral rectus, obliques, QL and iliopsoas
What other muscles contribute to trunk function?
pecs, traps, lats, SA, Rhomboids, QL
What are main functions of the trunk?
stability and postural control, house vital organs, stable base for limb movements, , shock absorption and weight distribution
What is definition of trunk control?
ability to perform he movement patterns necessary for functional movement and to coordinate these movements with those of the extremities
What are trunk weight shifts?
movements which result in changes of weight distribution, posture and move COG
How do you test weight shift?
test in sitting, and demonstrate reaching and scooting to elicit the desired weight shift and/or passively move person first
What are two standardized tests often used to test trunk control?
Trunk impairment scale (TIS)
Trunk control test
What are the 3 subscales of the TIS?
static sitting balance
dynamic sitting balance
trunk coordination
Who was TIS originally developed for?
developed for CVA population but used for CP, MS, PD and more
What is the trunk control test?
used for CVA population or geriatrics with acute illness
