Bridging Neuroscience and Clinical Practice: Accelerating Stroke Recovery in a Pontine Infarction Case Through Neuroplasticity-Based Rehabilitation.

Foundational neuroscience is crucial to locating lesions, understanding current functional limitations, making correct prognoses, and designing holistic and realistic treatment plans for stroke patients. A model bridging neuroscience knowledge and clinical practice was assessed through a rare pontine infarction case. A 76-year-old patient suffered two consecutive right-sided pontine ischemic strokes, leading to significant motor and sensory abnormalities on the left side.

Purposeful movement across unpredictable environments requires quick, accurate, and contextually appropriate motor corrections in response to disruptions in balance and posture. These responses must respect both the current position and limitations of the body, as well as the surrounding environment, and involve a combination of segmental reflexes in the spinal cord, vestibulospinal and reticulospinal pathways in the brainstem, and forebrain structures such as the motor cortex. These motor plans can be heavily influenced by the animal's surrounding environment, even when that environment has no mechanical influence on the perturbation itself.

The frontal lobe is crucial and contributes to controlling truncal motion, postural responses, and maintaining equilibrium and locomotion. The rich repertoire of frontal gait disorders gives some indication of this complexity. For human walking, it is necessary to simultaneously achieve at least two tasks, such as maintaining a bipedal upright posture and locomotion.

Humans are able to control their posture in their daily lives. It is important to understand how this is achieved in order to understand the mechanisms that lead to impaired postural control in various diseases. The descending tracts play an important role in controlling posture, particularly the reticulospinal and the vestibulospinal tracts (VST), and there is evidence that the latter is impaired in various diseases.

Stroke-related damage to the crossed lateral corticospinal tract causes motor deficits in the contralateral (paretic) limb. To restore functional movement in the paretic limb, the nervous system may increase its reliance on ipsilaterally descending motor pathways, including the uncrossed lateral corticospinal tract, the reticulospinal tract, the rubrospinal tract, and the vestibulospinal tract. Our knowledge about the role of these pathways for upper limb motor recovery is incomplete, and even less is known about the role of these pathways for lower limb motor recovery.
