Stroke and traumatic brain injury (TBI) are brain-based injuries that impair the nervous system’s ability to regulate posture, movement, muscle tone, and coordination against gravity. Although the mechanisms of injury differ, both conditions are often associated with similar sensorimotor challenges, such as muscle weakness, altered muscle tone, balance impairments, asymmetrical movement patterns, and increased reliance on compensatory strategies.
Vasa Concept offers a rehabilitation approach that expands beyond thinking focused on individual muscles or isolated symptoms. Instead, it views the interaction between the brain, the body, and gravity as an integrated, self-organizing system, with particular emphasis on regulation of the body’s center of mass and internal postural control. (Vasa Concept e-book.)
A core principle of Vasa Concept is that following brain injury, the nervous system reorganizes itself around one primary goal: safeguarding the body’s center of mass and preventing falls. In practice, the brain’s most essential task becomes protecting itself from impact.
After brain injury, this often manifests as:
flaccid paralysis progressing toward stiffness or spasticity
abnormal synergistic movement patterns
asymmetrical posture and uneven distribution of weight and load
overuse of the less-affected side
avoidance of loading the affected side
Vasa Concept does not interpret these phenomena primarily as errors or failures, but as logical survival strategies of the nervous system. A stiffer limb held closer to the body poses less threat to balance than a freely moving flaccid limb.

In traditional rehabilitation, spasticity is often treated as an isolated symptom to be reduced or inhibited. Vasa Concept offers an alternative interpretation: spasticity can function as a protective “brake,” through which the central nervous system limits movement in order to maintain safety of the body’s center of mass.
After brain injury, spasticity, stiffness, and restricted movement ranges may:
prevent uncontrolled movements
thereby increase joint and segmental stability
reduce the risk of falls (whereas flaccidity would increase risk)
When rehabilitation focuses on the body’s ability to balance and regulate loading of the center of mass, the central nervous system no longer needs to rely on spasticity as a protective mechanism. As body control improves, spasticity may decrease naturally without directly “fighting” it. This change is supported by increased proprioceptive input and richer sensory information from the affected side of the body.
Vasa Concept intentionally works with gravity rather than attempting to avoid it. Gravity is a constant force, requiring continuous postural adaptation, especially during activities such as sitting, standing, and walking.
In brain injury rehabilitation, this means that training is not based solely on voluntary, task-oriented movement. Instead, the focus is on:
body alignment and posture
internal distribution of body weight
how the body learns to function with gravity in different positions
Vasa Concept aims to expand the body’s safe movement boundaries, not by forcing performance, but by creating better conditions for movement generation.
In the video, in Juuso’s motor progress, improved control of the center of mass can be observed.
After brain injury, most individuals quickly learn to compensate by relying on the non-affected or less-affected side of the body.
While compensation may restore functional independence in the short term (and may be necessary, for example, for discharge home), in the long term it often:
increases load and fatigue on the healthier side
reinforces asymmetry
limits recovery potential of the affected side
Vasa Concept does not prohibit compensation, but seeks to prevent harmful compensatory patterns by restoring the affected side’s ability to participate in postural support and movement. When both sides of the body can alternately contribute to regulation of the center of mass, movement becomes more variable, energy-efficient, and automatic again.
Because Vasa Concept is not based on performance, but on dialogue between the central nervous system, the body, and the environment, it is suitable for:
acute, subacute, and chronic stages of rehabilitation
individuals with severe or milder functional impairments
people of all ages
Training can be carried out in everyday contexts and safe environments, including at home. This supports long-term rehabilitation and strengthens the active role of both the individual and their close ones in recovery.
In the video, Parnasi demonstrates what kind of recovery is possible when fully committing to the Vasa Concept.
Vasa Concept is a recommended approach for brain injury rehabilitation because it:
aligns rehabilitation goals with the central nervous system’s need for safety
reframes spasticity and atypical movement patterns as keys to understanding recovery
supports improvement in regulation and loading of the body’s center of mass
reduces the need for constant compensation
enables more automatic and energy-efficient movement
Vasa Concept is based on an understanding of the body as a self-organizing whole. Meaningful change occurs when the body is given the opportunity to function more safely and flexibly in relation to gravity allowing rehabilitation to progress from compensation toward more authentic restoration of movement control.
