    • reflexive in nature, not sustained or well coordinated
    • can be facilitated with: guided mvmt, icing, quick stretch, traction
  13. What occurs during the stability control stage?
    • able to maintain a position despite the influence of gravity
    • maintains position or posture through a co-contraction (muscle stability) and tonic holding (postural stability) around a joint
    • unsupported sitting with midline control, head control in prone pivot, prone on elbows, quadraped, squat

    can be facilitated with approximation, alternating isometrics, and rhythmic stabilization
  14. What occurs during the controlled mobility stage?

    • ADLs, community ambulation, crawling

    can be facilitated with resisted motion to increase proprioceptive feedback
  16. Who developed NDT (neurodevelopmental treatment)?
    bobath

    karl and berta
  17. What is NDT?
    • neurodevelopmental treatment
    • common intervention for hemiplegic pts
    • believed that abnormal postural reflex activity and muscle tone is caused by loss of CNS at the brainstem and spinal cord levels
    • dysfunction leads to slowing of motor development and inhibition of righting and equilibrium reactions and automatic mvmts

    purpose of PT is to inhibit abnormal postural reflexes and to facilitate normal patterns, such as head and trunk control, balance reactions, and UE support

    • facilitation- elicits voluntary muscle contraction
    • inhibition- decrease excessive tone or mvmt
    • *head injury
  18. What are the key points of control for NDT?
    • handling (shld, pelvis, hand, foot) to influence posture, alignment, control
    • *by manually controlling the pelvis, you can improve trunk posturing to perform a functional activity such as walking with an improved gait or increased ROM in the arm to reach for objects
    • placing- pt musch hold placement against gravity
  19. What method is based on sherrington and the reflec stimulus model?
    ROOD
  20. What is ROOD?
    • believed all motor output was result of both past and present sensory input
    • goal of apporach is to obtain homeostasis in motor output and activate muscles and perform tasks independently of a stimulus
    • once response is obtained, stimulus should be withdrawn

    • facilitation- approximation and compression, icing, light touch, quick stretch, resistance, tapping, traction
    • inhibition- deep pressure, prolonged stretch, warmth, prolonged cold, carotid reflex
  21. What is the ayers method?
    based on sensory integration and the impact of sensory processing on learning, emotions, and behavior
