Intensity matters! In the fourth and final of a multi-part series on stroke, Dr. Michael Powers explores best current evidence in stroke interventions including task-oriented training, clinical practice guidelines to improve locomotor function, and clinical practice guidelines on the use of ankle foot orthoses and functional electrical stimulation. He highlights the importance of keeping intensity, salience, and repetitions high during stroke rehabilitation to drive neuroplasticity. He discusses the importance of emphasizing interventions at the participation and activity level, and how treatments which overly emphasize body function and structure are not consistent with the best current evidence nor the recommended approach to examination which was discussed last episode. He hopes that by the end of this episode you will start thinking of your patients as athletes who benefit from high intensity practice!

Key Takeaways

• Neuroplasticity mechanisms
• Adaptive vs maladaptive neuroplasticity
• Lifestyle facts impacting neuroplasticity
• Experience-dependent neuroplasticity
• Factors impacting neuroplasticity
• The importance of exercise and intensity
• Aerobic exercise and brain-derived neurotrophic factor
• Non-locomotor outcomes improved with high intensity gait training

Begin with the end in mind! In the third of a multi-part series on stroke, Dr. Michael Powers advocates for starting the examination with collaborative goal setting focused on participation. He outlines how working backward from participation to activity and then body function and structure optimizes therapeutic alliance and helps drive neuroplasticity by emphasizing what is salient to the patient. He then discusses the importance of the review of systems and systems review (and how to distinguish these potentially confusing terms!), before concluding with an evidence-based framework for movement and task analysis.

Key Takeaways

• Importance of collaborative goal setting with emphasis on participation
• Biopsychosocial model and impact on salience and neuroplasticity
• Stroke Impact Scale
• Key factors impacting Quality of Life after stroke
• Prevalence and impact of depression after stroke
• Evidence-based screening for depression
• Review of systems and systems review
• Using the Movement Continuum to analyze tasks
• Standardizing terminology - glossary of terms for movement analysis

Not everything is weakness! In the second of a multi-part series on stroke, Dr. Michael Powers highlights the role of abnormal synergies and spasticity on movement and functional difficulties after stroke. Along the way, you'll learn about stereotypical synergy and spasticity patterns, motor recovery expectations, tools to examine synergies and spasticity, and how to consider synergies and spasticity within an evidence-based plan of care for stroke rehabilitation.

Key Takeaways

• Acute stroke response and flaccidity
• Abnormal synergies and impact on movement
• Stages of motor recovery following stroke
• Outcome measures for synergies: STREAM and Fugl-Myer
• Spasticity as part of the upper motor neuron (UMN) syndrome
• Strongest spasticity components for the upper and lower extremity
• Examining spasticity: Modified Ashworth Scale and Tardieu Scale
• Moving Forward: contextualizing synergies and spasticity within best current evidence

Time to talk stroke! In the first episode of a multi-part series on stroke, Dr. Michael Powers discusses stroke risk factors, the importance of early detection including the value of BEFAST and HINTS, and presentations of common vascular syndromes. Along the way, you'll learn about the differences between ischemic and hemorrhagic strokes, and how despite these differences the functional outcomes between these types of strokes is fairly similar. As 1 in 4 adults over the age of 25 will sustain a stroke in their lifetime, this is a vital topic for all physical therapists regardless of practice area!

Key Takeaways

• Prevalence/incidence of stroke
• Stroke risk factors
• PT role in educating patients on modifiable risk factors
• Time is brain
• Early detection: FAST, BEFAST, and HINTS
• Ischemic vs hemorrhagic stroke - differences in medical management, similarities in functional outcomes
• Vascular syndromes: ACA, MCA, PCA, which is most common?
• Hemispheric differences

Time to talk about good ol' carpal tunnel syndrome! In this episode, Dr. Michael Powers discusses key considerations of managing carpal tunnel syndrome, including the importance of patient history and the use of evidence-based practice in clinical-decision making. He also highlights the importance of knowing your anatomy, including knowing the unforgiving structure of the carpal tunnel (how many flexor tendons are squeezed in there?) and recalling peripheral nerves are complex structures composed of multiple neurons functionally grouped together in fascicles. This episode is a must-listen if you're wanting to improve your confidence in applying the evidence toward the diagnosis, prognosis, and management of carpal tunnel syndrome!

Let's learn about the brain! In this episode, Dr. Michael Powers introduces the cerebral cortex including the four main lobes (and wait, is there maybe a 5th lobe?), differences between the left and right hemispheres, and the importance of the limbic system. If you've ever wondered where in the brain language is processed, memories are stored, commands for movement are generated, where incoming sensation is interpreted, or the role of emotions in memory consolidation then this episode is for you!
