  1. name, origin, insertion, function
    • sartorius
    • O: ASIS anterior superior iliac spine
    • I: proximal medial tibia
    • F: flexion, lateral rotation
  2. name, origin, insertion, function
    • tensor fascia latae,
    • O: iliac crest
    • I: lateral tibial condyle
    • F: flexion, abduction
  3. name, origin, insertion, function
    • rectus femoris,
    • O: anterior iliac spine (AIIS)
    • I: patella and tibial tuberosity  via patellar ligament,
    • F: flexion (kicking)
  4. 4 sensory systems in posture
    • 1) somatosensation: self perception
    • 2) proprioception: detects muscle length
    • 3) vision
    • 4) vestibular: ear
  5. Types of postural adjustment:
    • 1) anticipatory
    • 2) compensatiory: hip,ankle, step, suspend
  6. what's the suspensory strategy
    arms out, squat, bend down.
  7. age of child: lifting head off support
    surface - requires sufficient neck
    and arm strength and ability to
    sense and integrate information
    concerning head orientation.

    Pull-to-sit test: insufficient head/neck flexor muscle control (head lags).
    2 months
  8. age of child: upright sitting -
    require sufficient neck and trunk
    muscle strength and ability to
    sense head and trunk position in
    Posture and Motor Milestones

    Pull-to-sit test:actively flexing the neck.
  9. age of child: creeping/crawling &upper
    extremity control and strength
    8-10 months (pull to stand)
  10. age of child: lower extremity control and strength. (cruising)
    9-10 months
  11. age of child: maintain
    balance with legs and trunk only. (unsupported standing).
    12-13 months
  12. age of child: increases in
    leg strength and coordination. (independent walking)
    14-18 months.
  13. Types of muscle recruitment
    • 1) Type I (always recruited during exercise)
    • 2) Type I+IIA
    • 3) Type I+IIA+IIB
  14. the sternocleidomastoid turns does what functions
    • contralateral rotation &
    • bilateral flexion
  15. what is contralateral rotation
    the way the sternocleidomastoid turns the head.
