General Info- EXAM 1 Flashcards
how long does it take to get muscle hypertrophy
about 6-8 weeks
what is the vision statement
transforming society by optimizing movement to improve the human experience
what is important to explain to our patients
why are getting someing prescribed
what is motor control
necessary input,
sufficiency processed,
with an acceptable outcome
what is motor control about
timing NOT strength
**we want the muscles to respond to the right timing of when the muscles moves
what is the necessary input of motor control
Afferent information synapses on dorsal root ganglion (1st order neuron)
Enters dorsal horn of the spinal cord
what do ascending pathways do
carry afferent information to the brain
what are ascending pathways
Dorsal Column Medial Lemniscus tract
Spinocerebellar tracts
Spinothalamic tracts
where are things sufficiency processed
primary motor cortex
primary somatosensory cortex
what does the descending pathways do
Originate within the Cerebral cortex or brainstem.
what are some descending pathways
Lateral corticospinal tract Ventral corticospinal tract Lateral reticulospinal tract Medial reticulospinal tract Rubrospinal tract Vestibulospinal tract Tectospinal tract
what are the alpha motor neurons
Lower motor neuron located in the spinal cord (or brain stem) is the lowest level
where are the alpha motor neuron located
located within the ventral horn of the spinal cord
what are the final common pathway of the motor system
alpha motor neurons
- Supraspinal motor tracts
- Spinal interneurons
- Primary sensory afferent fibers
what is the acceptable outcome of motor control
which we observe as moment
what are things that alter motor control
pain
injury

what are some pain theories
- vicious cycle
- pain adaptations
- new pain model
what is the vicious cycle of the pain theories
In the presence of painful stimuli muscle activity increases
- Regardless of the task
- Stereotypical
what is the pain adaptations of the pain theories
1The activity of muscles that are painful or produce painful movement are decreased
***Force generating ability reduced
2The antagonist of these painful muscles are increased
what is the new pain model of the pain theories
- Involves changes in multiple levels of the motor system
- Changes mechanical behavior; dysfunctional movement
- Leads to protection of further injury
- Short term benefit; long term consequence (protection)
- Redistribution of activity between and within muscles
what is the inner core
Diaphragm
Transverse abdominis
Pelvic floor
Multifidus
how does pain alter motor control
in an unpredictable manner
what is high threshold strategy
Adaptive strategy mediated by the CNS in response to pain where there is increased neural drive to the global muscular
Although designed for a short term response…..in many individuals it may become a detrimental pattern
The outer muscles are on excssively when performing a low load task
look at slide
40-49
where do poor movement patterns exist
in the BRAIN
discrete task
(clear beginning and ending)…most therapeutic exercises are discrete tasks
serial tasks
: A series of discrete tasks combined in a particular fashion…..such as taking a bite to eat or transfer to/from a wheelchair independently
continuous task
Repetitive, uninterrupted movements with no distinct beginning and ending….walking, cycling etc.
