What Is Neurorehabilitation?
Neurorehabilitation encompasses the full range of therapeutic interventions aimed at restoring neurological function and helping patients regain independence following injury to the nervous system.
It covers a broad spectrum of conditions, including stroke, traumatic brain injury, spinal cord injury, neurological complications of surgery, post-viral neurological dysfunction and chronic neurological disorders.
The fundamental objective of neurorehabilitation is to harness neuroplasticity, the brain’s inherent ability to reorganize its neural connections, form new neuronal networks and transfer lost functions to healthy regions.
This capacity is greatest during the early period following injury and gradually diminishes over time, making the timing of rehabilitation a critical factor in the final outcome.
Characteristics of Neurorehabilitation
Neurorehabilitation must be tailored to the individual patient. There is no single protocol suitable for everyone. The type, location and severity of the injury, together with the patient’s age and general state of health, determines the rehabilitation plan.
A multidisciplinary team comprising a neurologist, physiotherapist, occupational therapist, speech and language therapist and psychologist forms the foundation of effective neurorehabilitation.
A central consideration is that neuroplasticity depends on the energy status of neurons. Cells experiencing energy failure because of hypoxia or metabolic stress cannot respond adequately to rehabilitation stimuli.
Improving oxygenation is therefore not merely beneficial; it is a prerequisite for effective rehabilitation.
Scientific Studies
Studies examining the combination of hyperbaric oxygen therapy and intensive neurorehabilitation have reported significantly better outcomes than either rehabilitation or hyperbaric oxygen therapy alone.
This synergy appears to work in both directions. Hyperbaric oxygen therapy creates more favourable biological conditions for neuroplasticity, while rehabilitation provides the targeted stimuli required to develop and strengthen the relevant neural pathways.
Neuroimaging studies using functional magnetic resonance imaging (fMRI) and single-photon emission computed tomography (SPECT) have demonstrated increased brain activity in previously underactive regions following a course of hyperbaric oxygen therapy. These findings directly reflect improvements in neuronal viability and function.
The Role of Hyperbaric Oxygen Therapy
In neurorehabilitation, hyperbaric oxygen therapy acts as a biological enhancer. It does not replace any aspect of the rehabilitation programme but improves the biological conditions in which rehabilitation takes place.
Each session improves oxygen delivery to brain tissue surrounding the affected area, stimulates neurotrophic factors that support the formation of new synaptic connections, reduces the neuroinflammation that inhibits neuroplasticity and improves the energy status of underactive neurons.
The result is a brain that is better able to respond to the stimuli provided through physiotherapy, occupational therapy and speech and language therapy.
The treatment course is fully individualized and typically consists of 40 to 60 sessions. It is delivered alongside the principal rehabilitation programme and coordinated by the neurological team.
