Q

Stages of motor learning (3)

A
  1. Skill acquisition stage (cognitive stage): occurs during initial instruction and practice of a skill.
  2. Skill retention stage (associated stage): “carry-over” as person is asked to demonstrate their newly acquired skill after initial practice.
    3 Skill transfer stage (autonomous stage): the person demonstrates the skill in a new context.

Q

Factors/conditions that promote generalization of motor learning:

A
  • capacity to generate intrinsic feedback
  • high feedback regarding knowledge of performance
  • low extrinsic feedback regarding knowledge of results
  • practice conditions that are variable, random
  • whole task performance as opposed to breaking activities into parts
  • high contextual interference utilizes enviro that increases the difficulty of learning (noise, crowded enviro, random practice)
  • practice in naturalistic settings.

Q

Neurodevelopmental Treatment (NDT) (The Bobath Technique)

A
  • normalization of postural and limb tone is prerequisite to normal movement.
  • inhibition of primitive reflexes and abnormal postural and limb movements
  • postural reactions are considered the basis for control of movement (righting, equilibrium, and protective responses)
  • focus is on improving quality of movement
  • handling is the primary intervention to promote normal movement

Q

Proprioceptive Neuromuscular Facilitation (PNF)

A
  • assumption: the response of the neuromuscular mechanisms can be hastened through stim of the proprioceptors
  • techniques are superimposed on patterns of movement (diagonals) and posture, focusing on sensory stim from manual contacts, visual cues, and verbal commands.
  • normal motor dev proceeds in a cervicocaudal and proixmodistal direction
  • frequency of stim and repetitive activity are used to promote and retain motor learning, and to develop strength and endurance.

Q

Margaret Rood’s Approach

A
  • sensorimotor control is developmentally based; tx must begin at person’s current level and progress sequentially.
  • 4 sequential phases of motor control:
    1. reciprocal inhibition/innervation (an early mobility pattern that is primarily a reflex governed by spinal and supraspinal center)
    2. co-contraction (a simultaneous contraction of agonist and antagonist that provides stability in static pattern.)
    3. heavy work (“mobility superimposed on stability”… proximal muscle contract and move and distal segments are fixed.)
    4. skill (the highest level of control- combines stability and mobility. Stabilized proximal segment while distal segments move in space.)
