The human brain is a dynamic, ever-changing entity that has the remarkable ability to adapt and reorganise itself. This concept, known as neuroplasticity, has revolutionised our understanding of brain function and recovery.
In rehabilitation, harnessing the power of neuroplasticity forms the foundation of neuroplasticity rehabilitation, unlocking new avenues for recovery and improvement and empowering individuals to reach their full potential.
To understand the value of neuroplasticity rehabilitation, it helps to explore how the brain adapts, rewires, and forms new pathways in response to training and lived experience.
What is Neuroplasticity?
Neuroplasticity is the brain’s ability to adapt and reorganise.
Changes in behavioural, sensory, and cognitive experiences drive this adaptive capacity of our central nervous system. It enables us to relearn skills, adapt to changes, and recover from injuries and illnesses.
Within rehabilitation, neuroplasticity is the brain’s ability to compensate for damaged areas by either enhancing existing connections or forming new connections and pathways. To form a new connection, imagine the brain’s neural pathways as the London Tube network.
When a familiar route is disrupted, you are initially forced to take a detour to get to your destination. However, with repeated use, a new route becomes more familiar and efficient for you.
This rerouting represents neuroplasticity, the brain’s ability to adapt and reorganise by forming new connections and neuronal circuitry. Just as you find alternative travel routes, the brain finds alternative pathways to compensate for damaged areas and get you to your destination.
Neuroplasticity allows us to:
- Relearn skills and knowledge
- Adapt to changes in our environment
- Recover from injuries and illnesses
- Compensate for cognitive or physical impairments
Mechanisms Behind Neuroplasticity Rehabilitation
The remodelling of our neuronal processes is constantly occurring in all our brains via biochemical, physiological, genetic, and structural mechanisms that respond to and learn from our lived experiences and functional demands.
This ability of our brains to change supports the enhancement of functional activities through rehabilitative mechanisms. This change, or neuroplasticity, occurs via the following mechanisms:
- Remodelling of neuronal processes and enhancement of existing connections, such as strengthening necessary synapses, is facilitated by the excitatory postsynaptic potential. Unused connections experience long-term depression and are deleted over time, a process called ‘synaptic pruning’.
- Production of new neural connections and synapses is called ‘synaptogenesis’.
- Generation of new cells – such as ‘sprouting’, whereby our brains experience an increase in synapses, dendrites, and axons.
Influences on Neuroplasticity
It may sound complicated, but neuroplasticity is a process our brains have been undergoing since birth. However, the process can be influenced by various aspects, including your environment, motivation, nutrition and hydration, sleep, genetics and pre-injury health.
Your environment needs to be conducive and provide opportunities for you to practice the desired skill you wish to achieve. Whether that is at home, the gym, or at work, creating the best place for you to concentrate and complete your rehab is crucial.
Your full engagement and sustained attention while practising a new skill repetitively are critical. This motivation to participate will not only allow your brain to learn a skill, but it also activates the hypothalamus, which stimulates protein synthesis – the building blocks of new neural circuitry.
Lifestyle factors, including nutritional intake and hydration, are crucial for supporting the development of underlying physiological neural circuitry. Proper hydration is essential for brain health as the brain relies on water for all its functions. Even a mild period of dehydration can cause a reduction in cognitive performance, memory, and attention span.
Genetics also plays a role; some people’s family history may have a more positive influence on their neuroplasticity and support adaptability compared to others. Additionally, your overall health and well-being before your injury or condition will impact the success of your recovery.
Principles of Neuroplasticity
Below are some key principles of neuroplasticity to help guide further knowledge and application:
Use it or Lose It: This old adage is certainly true when it comes to our brains. Activities that are not used will begin to degrade over time. Practicing functional tasks helps prevent loss of these abilities.
Use it and Improve it: Our brains demonstrate a capacity for plasticity in functions that are trained extensively. Personalised goal setting helps identify the skill to be improved, and then we target our intervention accordingly.
Specificity: You wouldn’t do bicep curls every morning to improve your standing balance. Training results in changes to synaptic and motor maps in brain areas that specifically control the trained function. Consistent training of the specific muscle and/or skill you want to improve is paramount.
Repetition: One of the biggest questions is how many repetitions are needed to induce lasting neural changes? Approximately 400 to 600 reps is a good starting point.
Intensity: In addition to repetition, daily practice is necessary to induce plasticity. Practice skills regularly over a period of time to improve.
Time: You can benefit from therapy treatment at any stage of neurological conditions or recovery, but acute rehabilitation must be prioritised. Neural restructuring promoted by rehabilitation can occur throughout your rehabilitation journey, but training is most effective early after the injury.
Salience: What activities are meaningful and essential to you? Everyone engages most strongly in activities we value and from which we receive reward, so choosing a salient activity will result in greater plasticity changes.
Age: All brains are adaptable. However, older brains are less responsive to experience than younger brains. Age is linked to psychological age (impacted by lifestyle) more than chronological age.
Transference: When we practice one task, it can help us improve in another. This is seen in athletes who sometimes switch disciplines but continue to compete at an elite level.
Interference: Alternatively, when we practice one task, it may hinder us in another. This can occur by preventing new neural circuits from forming or dampening the expression of existing ones. Therapists can support by identifying compensatory strategies and promoting strengthening weaknesses.
Where Neuroplasticity Rehabilitation Helps Most
Neuroplasticity-based approaches can be applied to various conditions, including:
- Stroke: Neuroplasticity enables the brain to reorganise and compensate for damaged areas, allowing individuals to regain lost functions.
- Traumatic Brain Injury: Neuroplasticity-based therapies can aid individuals in recovering from traumatic brain injuries by facilitating neural adaptation and compensation.
- Neurodegenerative Diseases: Neuroplasticity-based approaches can help individuals with neurodegenerative diseases, such as Alzheimer’s, Dementia, or Parkinson’s disease, adapt and compensate for cognitive and motor decline.
Techniques for Harnessing Neuroplasticity
Several therapeutic techniques can be used to promote recovery and improvement, including functional task practice, constraint-induced movement therapy (CIMT), and cognitive training. By leveraging neuroplasticity, Remedy Health and Performance therapists can:
- Enhance motor and cognitive function
- Improve daily functioning and independence
- Support personalised rehabilitation plans
By understanding and harnessing neuroplasticity’s power through neuroplasticity rehabilitation, we can unlock new possibilities for recovery, empowering you to reach your full potential and return to the activities you love.
