Neurological Physiotherapy: Neuroplasticity and motor recovery · Principles of Experience-Dependent Plasticity

How the brain rewires in response to practice, and the principles that turn that into effective rehabilitation.

For learning, not medical advice: for your own health, ask a doctor or another qualified professional.

Try 3 questions

1. Experience-dependent plasticity means the brain reorganizes mainly in response to what?

  1. The activities a person repeatedly performs
  2. Medications that protect damaged neurons
  3. The time that passes after an injury
Show the answer

Answer: The activities a person repeatedly performs

Synapses and cortical maps reshape themselves around the behaviors a person actually practices, which is why rehabilitation centers on active training rather than waiting.

2. In Kleim and Jones's principles of plasticity, what does "use it or lose it" warn about?

  1. Overtraining can erase newly formed synapses
  2. Old motor habits block all new learning
  3. Neural functions left unused can degrade
Show the answer

Answer: Neural functions left unused can degrade

When a function is not driven, its neural circuits weaken; for example, the cortical area for a limb that goes unused after a stroke tends to shrink.

3. A stroke survivor squeezes a grip ball daily but still can't button a shirt. Which plasticity principle best explains the limited carryover?

  1. Specificity
  2. Intensity
  3. Salience
Show the answer

Answer: Specificity

The nature of the training determines the plasticity: squeezing reorganizes circuits for squeezing, so fine tasks like buttoning have to be practiced themselves.
