what are the peripheral consequences (neuromotor impairments) following injury?
afferent (sensory) can be altered (e.g., mechanoreceptors in skin, ligaments, muscles, tendons)
efferent (motor) output can be altered (e.g., muscle inhibition altering muscle contractions)
**these neuromotor impairments may be assessed and treated to restore both afferent and efferent (sensorimotor) pathways
neuromotor exercise involves developing motor skills such as: _____
activation
balance
coordination
agility
proprioception
what is activation?
the ability to voluntarily contract a skeletal muscle in isolation
what is the clinical indication of an activation issue?
following injury clients may be unable to voluntarily fully contract an otherwise healthy muscle - such as when there is an ACL injury at the joint (e.g., arthrogenic muscle inhibition (AMI))
how could you test the ACTIVATION of vastus medialis?
1) ask the client to contract the muscle
2) observe for isolated muscle contraction and signs of associated function
3) palpate muscle to determine degree and duration of voluntary contraction before fatigue
what is agility?
the ability to change direction to achieve a specific goal
how could agility be assessed?
using the Modified Agility ‘T’ Test
- uses a series of movements where an athlete starts at a specific line and travels forward, backwards, side to side, accelerates, decelerates, etc.
what is balance?
refers to the complex motor control process that integrates relevant sensory information (i.e., visual, proprioceptive, vestibular) to execute appropriate motor actions to control body positions in the context of the environment and the task
how is balance maintained?
it is maintained when the center of gravity is within the base of support
what is an example of a static and a dynamic balance test?
static - balance error scoring system (BESS)
dynamic - y balance test (measures and compares bilaterally)
what is coordination?
the ability to execute accurate, smooth, controlled movement patterns
how could coordination be assessed?
by observing the quality of a single leg squat test
- knee vs hip dominant
- dynamic knee valgus
what are the 5 things considered for a good rating on the single leg squat test?
ipsilateral trunk lean
pelvic tilt
hip adduction or internal rotation
dynamic knee valgus
loss of balance
what is proprioception?
the ability to sense limb movement and positioning in space
how could proprioception be measured?
may be measured through joint position sense (ability to reproduce a joint position)
what does the Clinical Practice Guidelines recommend neuromotor exercise for?
resolving neuromotor impairments
reduce injury recurrence risk
what are the 6 treatment principles of neuromotor exercise?
frequent practice
meaningful practice
vary sensory input
attentional focus
implicit learning
autonomy
purpose of meaningful practice?
stimulate the clients’ function / goal
- want to give tasks that are important and challenging to the client
purpose of varying sensory input?
to either amplify or occlude sensory inputs
- adding foam challenges proprioception
- closing eyes creates an increase demand from the other senses
- turning head while on foam challenges the vestibular system
what are the 4 types of cueing you can use in varying sensory input for clients?
auditory
imagery
proprioception (monitor back arch with hands)
visual (demonstration/mirror)
what is the purpose of external vs internal focus for attentional focus component?
internal is focus on self
external is focus on environment
- focus on self is more conscious and can disrupt automatic control tendencies
- ex of internal could be “bend your knee so it sits over your toes”
- ex of external would be “reach your knee towards to cone infront of you”
what is the difference between implicit and explicit learning?
in explicit learning you are overloaded with external information, increasing errors and overloading your working memory
in implicit learning you are promoting more automatic or internal processes, leading to less errors, and reducing the load on your working memory
LESS INSTRUCTION IS BETTER FOR MEMORY
why is autonomy important for motor learning?
patients tend to assume a passive role, but CHOICE is important for motor learning
what is the general FITTVP for healthy adults and treating neuromotor impairments?
F - 2 -3 times per week
I - optimal is unknown
T- 20-30 mins per day
T - balance, agility and coordination
V - optimal is unknown
P - optimal is unknown
