Rehabilitation Applications Flashcards
Can you use the overload principle with individuals with a neurologic injury?
yes!
Where does overload principle fall under the principles of neuroplasticity?
intensity matters
What is BDNF?
a protein called brain derived neurotrophic factor
How does training affect BDNF?
upregulates
What are two strategies to assist in motor recovery related to neuroplasticity?
constraint induced movement therapy
body weight support treadmill training
What is constraint induced movement therapy?
intense “massed” practice of using affected limb while restraining the unaffected limb
What does body weight supported treadmill training help with?
movement of treadmill triggers central pattern generators to create alternating limb motor pattern
can elicit excitement of central pattern generators
What is an example of body weight supported treadmill training?
- walk as fast as possible, 2 mph
- 3 people holding legs
What are the 2 theoriess that explain body weight supported treadmill training?
- spinal-modulated reflex (CPG)
- cortical control/input
What should PTs be doing to increase walking speed and endurance in near patients?
- moderate-high intensity walking training > 60% HR
- high intensity walking training (massed practice)
- paired with augmented feedback/virtual reality
Which type of intensity promotes more regulation of BDNF?
high intensity
How does synaptogenesis allow us to use volitional signal to move through descending tracts?
neural sprouting takes advantage of interneurons to bypass the lesion to get to the target muscle
How did epidural stimulation help complete spinal cord injury patients?
stimulation allowed for volitional control leading to weight bearing
What is the theory behind transcutaneous spinal stimulation?
if the descending signal is blocked, may be spared descending pathway signals that can get through and around the lesion
- connection may not be strong enough to fire action potential so it needs the stimulation (applied below level of injury)
What are the characteristics of an UMN injury?
- lack of descending control
- weakness
- hyper reflexia
- hypertonia
- spasticity: less motor control due to less descending control
- clonus
- primitive synergies
