The flashcards below were created by user jpowell22 on FreezingBlue Flashcards. What would you like to do?


  1. What is a righting reaction?
    automatic mvmt that occurs when another part of the body has active or resistive mvmt
  2. What muscle groups do you resist to achieve synkinetic foot inversion and DF? (ant. tib.)
    • sitting or supine
    • resist hip flexion
    • resist hip adduction at foot
  3. What muscle groups do you resist to achieve synkinetic hip abd? (gluteus medius)
    • prone or supine
    • resist arm abduction
  4. What muscle groups do you resist to achieve synkinetic hip ext? (glutes maximus, HS's)
    • supine: legs hanging over edge of table, flex hip and knee up and resist knee ext and PF
    • prone: with knee flexed, resist PF and knee ext; add resisted back ext
    • sitting: with hips in acute flexion, resist PF
  5. What muscle groups do you resist to achieve synkinetic knee flexion? (HS's, popliteus, sartorious, gracilis, gastroc)
    • sitting or supine
    • resist hip flexion
    • resist trunk flexion and neck flexion
  6. What muscle groups do you resist to achieve synkinetic shld flex? (deltoid, coracobrachialis)
    • supine
    • resist neck flexion
    • add resisted trunk flexion and hip flexion
  7. If you maximally resist hip flexion, what occurs at the knee and ankle?
    • knee flexion
    • DF
  8. If you max resist trunk ext while prone, what occurs at the hip, knee, and ankle?
    flexion, DF
  9. If you max resist neck flexion (shld elevation) what occurs with the upper extremities?
    • shld flexion
    • elbow ext
    • neutral wrist
  10. If you max resist neck ext what occurs with the upper extremity?
    shoulder and elbow ext
  11. What is a reaction prior to birth, or integrated during the first 4-6 months?
    primitive reaction
  12. What places a primitive reaction and is usually fully developed by 6 months?
    mature reactions
  13. What is a righting reaction?
    • align the head and trunk, attempting to obtain a vertical position against gravity
    • use head first to pull themselves back to neutral after leaning
  14. What is an equilibrium reaction?
    • automatic total body reactions made to maintain or control the COG in response to being moved
    • little rotation and weight shifting
    • multiplane
  15. What is the use of extremities for support to maintain an upright position in reponse to being moved?
    • protective reaction
    • develops before tilt reactions
  16. What is the automatic response of the body and extremities to control a shifting COG in response to being moved?
    tilt reaction
