Kleims Principles of Neruo Plasticity |
List Risati L - use it or lose it I - Use if and improce it S - Specificity T - Time maters R - Repetition I - Intensity S - Salience A - Age T - Transference I - Interference |
|
|
Describe Use it or Lose it |
Failure to drive specific function leads to degradation of the function |
|
|
Describe Use it and Improve it |
Training that drive specific function will tend to improve that function |
|
|
Describe specificity |
The nature of the training experience dictates the nature of the plasticity |
|
|
Describe Repetition |
Induction of plastic change requires sufficient repetition |
|
|
Describe Intensity |
Induction of plastic chance requires a high enough level of intensity to precipitate change |
|
|
Describe Time |
Different forms of plasticity occur at difference times during training |
|
|
Describe Age |
Training occurs more readily in young brains |
|
|
Describe Salience |
The training must be important enough to the pt to precipitate change |
|
|
Describe Transference |
Plasticity in response to one training experience can enhance acquisition of similar behaviors |
|
|
Describe Interference |
Plastic response to one experience can interfere with acquisition of other behaviors |
|
|
What can explain spontaneous recovery |
•Naturalhealing with recovery of blood flow and metabolism •Naturalcompensatory behaviors develop •Substantialneurophysiological and neuroanatomical reorganization following injury |
|
|
Describe the recovery of blood flow and metabolism theory |
•Diaschisis – an area of the brain, connected byneurons but remote to the area of focal injury, that experiences sudden loss offunction ---Associatedareas of brain undergo reduced metabolism and blood flow following injury ---Asa result of natural healing, reversal or resolution of this altered flow occurswithin first month of injury with concomitant improvement and return offunction |
|
|
Describe the compensatory movement theory |
Outcomes measure function but not quality of movement Shortly after injury, pts will develop compensatory movements using preserved proximal and axial muscles A repeated outcome will document improved function, but not the quality of mvoement |
|
|
Describe the reogranization of the brain theory |
Altered physiological response in intrinsic neuronal networks --Long term potentiation/depression Altered neuro transmitter levels Anatomical changes in neuron structure --Dendritic branching --Axonal sprouting --Synaptogenesis |
|
|
What is the temporal contiguity hypothesis |
The normal representation of body surface in the brain is maintained thru daily use Change the daily pattern of use, and in a relatively short period of time distribution within the cortical map changes |
