Neurological and Functional Complications
01
02
Pontine Gaze Pattern
•due to anterior circulation stroke
•looks toward the lesion site
•looks away from the hemiplegic side
•lesion site: area 8 or the frontal eye field of frontal lobe
•due to posterior circulation stroke
•looks away from the lesion
•towards the hemiplegic side
•lesion site: pontine nuclei
Frontal Gaze Pattern

24. depends on the type and location of the vascular lesion, as well as the severity of the clinical deficits.
Medical Management
aspirin and heparin
to improve flow through occluded vessels
and prevent further clotting or thrombosis
Anti-platelet and anti-coagulation drugs
01 Tissue plasminogen activator (t-PA): open
occluded cerebral vessels and immediately
restore circulation.
Limited, 3-6 hours after stroke onset
Thrombolytic drugs
02

25. Intervention Principles for
Stroke
Intrinsic Recovery
refers to the
remediation of
neurological
impairments
Adaptive Recovery entails
regaining the ability to
perform meaningful
activities, tasks, and roles
without full restoration of
neurological function
ACTIVE USE OF TASK-ORIENTED TRAINING
(Pendleton and Schultz-Krohn, 2018)
Help clients adjust to role and task performance
limitations by exploring new roles and tasks.
Create an environment that includes the common
challenges of everyday life.
Practice functional tasks or close simulations that have
been identified as important by participants to find
effective and efficient strategies for performance.
Provide opportunities for practice outside therapy time.
Minimize ineffective and inefficient movement patterns.

26. Utilization
Individuals with stroke are among one of the primary clients of occupational therapy
facilitate the client’s performance of needed or
meaningful occupations within realistic context
Working collaboratively with the members
of the rehabilitation team
provides healthcare professionals in
various practices with the fundamental
knowledge necessary to work with the
stroke population
focus the evaluation procedures and begin to
reflect on the client factors that may have been
impaired and that affect the client’s occupational
performance based on the brain lesions

27. Reflection
I was anxious as I prepared for this topic because stroke is one of the conditions I
consider complicated. Many terminologies must be discussed, including
anatomical structures and their physiological activities, as well as the
accompanying conditions that I find intimidating. For me, it is one of those
conditions that has been discussed numerous times but is still difficult to recall.
Still, I was thrilled to be assigned this topic because I see it as an opportunity to
go over everything that had been previously covered with us. I am not confident
enough to say that I have already improved in terms of application but I know that
using this fundamental knowledge is essential to understand the symptoms,
diagnosis, and management of stroke.

28. Thank You
So Much!
