PRELIMS: Stroke Rehab Flashcards
What is early neurological recovery following a stroke attributable to?
Early recovery is attributed to the resolution of edema, allowing structurally intact but nonfunctional neurons to regain function.
What drives functional recovery in stroke rehabilitation?
Functional recovery is driven by neurological recovery and rehabilitation efforts.
What does late neurological recovery involve?
Late neurological recovery involves neuroplasticity, where the brain reorganizes itself to compensate for lost functions.
Why is reperfusion of the ischemic penumbra critical?
Reperfusion allows nonfunctional but viable neurons to regain function and supports clinical recovery.
Why is functional recovery important?
It ensures that individuals can return to their daily activities and improve their quality of life.
What does cortical reorganization involve?
Cortical reorganization involves functional changes in the motor cortex due to skilled movement acquisition and injury-induced changes in remaining cortical tissue.
What is the ischemic penumbra?
The ischemic penumbra is a region surrounding the core infarct area where blood flow is reduced but still salvageable.
What is diaschisis?
Diaschisis is the loss or decrease in function of a brain region distant from the primary injury due to disrupted neuronal connections.
In which Brunnstrom stage does movement begin to emerge outside of synergy?
Stage 4.
What mechanisms contribute to the resolution of diaschisis?
Restoration of blood flow, neuronal plasticity, reestablishment of neural pathways, reduction in metabolic depression, and rehabilitation.
What are the mechanisms of neuroplasticity?
Neuronal regeneration/collateral sprouting and functional reorganization/unmasking.
What is a common lower extremity synergy pattern post-stroke?
Extension synergy (e.g., hip extension, knee extension).
Extension synergy (e.g., hip extension, knee extension).
Stage 1 is characterized by flaccidity with no voluntary movement.
What is a common upper extremity synergy pattern post-stroke?
: Flexor synergy (e.g., shoulder flexion, elbow flexion).
Stage 1 is characterized by flaccidity with no voluntary movement.
Marked spasticity with movement primarily in synergy patterns.
What is the role of tonic reflexes in Brunnstrom’s approach?
Tonic reflexes (TNR, TLR, tonic lumbar reflexes) help to initiate movements or inhibit undesired muscular responses by influencing muscle tone and movement patterns.
