Neuroplasticity, also known as Neural Plasticity, is an intrinsic ability of the central nervous system (CNS) to adapt and change itself because of internal or external stimulus. There is an important distinction between neural plasticity and neural regeneration, where regeneration is the ability of the central nervous system to regenerate and replace diseased or injured cells with healthy ones.
It’s a well-established fact that, unlike most other tissues in our body, our nervous system has a very limited capacity to regrow lost or injured cells, often resulting in severe or permanent loss of function. However, the CNS can adapt, change, and create new connections (called synapses) with surrounding cells to enhance its function and compensate for the loss of diseased or injured nerve cells. This is called neural plasticity.
Mechanisms of Neuroplasticity After CNS Injury
After trauma or injury to the CNS, neuroplasticity is achieved through two important mechanisms:
Neural Sprouting and Synaptic Plasticity
Synaptic plasticity refers to the CNS’s ability to make experience-dependent, long-lasting changes in the strength of neuronal connections. For example, after a spinal cord injury, consistently performing certain exercises forces the spinal cord to reorganize itself and create more permanent pathways, enhancing overall function.
Functional Reorganization
Functional reorganization is the ability of one part of the CNS to take over a function it wasn’t originally responsible for. In many spinal cord injury (SCI) patients, residual spinal pathways can overcompensate for the loss of other pathways, enhancing communication below the level of injury.
How to Enhance Neuroplasticity After Injury
The nervous system responds and reacts to various forms of internal and external stimuli, such as peptides, neurotransmitters, cytokines, and chemotactic proteins. Certain external stimuli and treatments can further enhance neuroplasticity after severe spinal cord or brain trauma.
Neurorehabilitation
Neurorehabilitation is vital for maintaining muscle strength, integrity, and function, while also forcing the CNS to reorganize itself and create new fibers and synaptic connections. Persistent, task-based, and muscle-focused rehabilitation has been associated with recovering certain muscle functions, which would otherwise be impossible. This improvement is due to neuroplasticity triggered by rehabilitation as an external stimulus.
Electrical, Electromagnetic, and Other External Stimuli
Different forms of electrical and electromagnetic stimulation act as powerful external stimuli to trigger neuroplastic changes. These stimuli directly interact with CNS tissue to promote adaptation and change.
Epidural Electrical Stimulation (EES)
EES is a powerful tool for enhancing neuroplasticity. It provides direct electrical currents to the spinal cord, significantly altering its function over time. Patients using EES over longer periods often demonstrate measurable improvements in spinal cord function and neuroplasticity.
Stem Cell Treatment
Stem cell treatment is a cutting-edge form of regenerative medicine that plays a crucial role in inducing neuroplasticity.
- Dual Role of Stem Cells: Stem cells can regenerate nerve tissue while also altering the function of existing tissues.
- Internal Stimulus: Stem cells have strong immunomodulatory properties that alter the microenvironment after an injury, promoting neuroplasticity.
- Optimal Timing: The regenerative potential of stem cells is highest during the early stages of injury, before scar tissue forms (astrogliosis). Thus, initiating treatments early maximizes their impact.
Real-Life Applications: Neuroplasticity Exercises for SCI Recovery
1. Patient: Thoriq
Injury Level: T12 complete
Treatment Received: LamiSpine (2019)
Thoriq’s neuroplasticity exercises for spinal cord injury recovery are tailored to rebuild strength and mobility in his lower body. Before treatment, he had no movement below the waist. Through personalized therapy, he is now working on improved control and coordination in his lower body.
2. Patient: Landon
Injury Level: T3 complete
Treatment Received: Stem Cell Treatment (November 2024)
Landon’s personalized neuroplasticity training targets his right ankle, which had no movement before treatment. These exercises focus on joint control and enhancing mobility, showing measurable progress in his lower limb functionality.
3. Patient: Karen
Injury Level: C4-C5 complete
Treatment Received: Epidural Stimulation (August 2022)
Karen’s neuroplasticity exercises are designed to strengthen her hands and fingers. Before treatment, she couldn’t move them at all. After continuous rehabilitation and therapy, she now performs these exercises independently, even without the stimulator, highlighting her impressive progress.
4. Patient: Nikita
Injury Level: C4 complete
Treatment Received: Epidural Stimulation (July 2022)
Nikita’s neuroplasticity exercises focus on arm mobility and building muscle strength. Previously unable to move his arms, he can now independently perform these exercises after ongoing therapy and adaptive rehabilitation.
5. Patient: Robert
Injury Level: C7-T1 incomplete
Treatment Received: Epidural Stimulation (February 2024)
Robert’s tailored neuroplasticity exercises help him regain the ability to push his legs. Before treatment, he couldn’t perform this movement. Now, after rehabilitation, he successfully completes these exercises without the stimulator, showing significant improvement in his motor control and strength.
Final Thoughts on Enhancing Neuroplasticity
Neuroplasticity offers hope for recovery after CNS injury by leveraging the brain and spinal cord’s ability to adapt and reorganize. From task-based neurorehabilitation to cutting-edge stem cell treatments, modern medicine provides innovative ways to harness this phenomenon, improving patients’ quality of life and independence.
