Intro Slides Flashcards
What 3 things does human movement emerge from?
person, task, environment
degrees of freedom
number of independent factors affecting a range of states in which a system can exist
or: number of different directions a joint can move
motor equivalence
multiple ways muscles/joints can act to solve a movement problem
what 3 systems interact to coordinate human movement
sensory/perceptual
motor/action
cognitive
motor control
how the neuromuscular system functions to enable coordinated movement
motor performance
movement behavior observed at a point in time
what 2 things are used to assess motor performance
outcome measures
performance measures
“what”
outcome measures
“how”
performance measures
a patient is performing a gripping task. you times how long they could hold it. is this an outcome or performance measure?
outcome
motor learning
persistent change in performance that occurs with practice and can be observed during acquisition, performance enhancement, and reacquisition
how do you assess motor learning
through changes in performance, persistency, consistency, stability, and adaptability
motor development
human development related to motor control and learning from infancy to old age
motor skill is an interaction between what two things
motor learning and motor development
a motor skill involved proficiency of a task with what four criteria
goal oriented
involves body or limb movement
voluntary
develops with practice
4 physical therapy goals for a skill
consistent
flexible
efficient
safe
primary musculature classification
gross or fine
large versus small muscles
is walking with crutches gross or fine?
signing a check?
gross
fine
task organization classification
discrete, serial or continuous
single movement vs. series of single movements vs. repetitive movement
is walking discrete or continuous? sit to stand? transferring from bed to wheelchair?
continuous
discrete
serial
environment classification
closed or open?
stable vs changing
what 3 things should you think about when observing the performance environment?
surface, object, people
regulatory conditions
environmental features that shape or mold a task
non-regulatory conditions
environmental conditions which do not directly influence movement characteristics
is the height of a basketball rim regulatory or non-regulatory? crowd noise?
regulatory
non-regulatory
gentiles taxonomy factors (5)
environment:
- stationary
- in-motion
action:
- stability
- mobility
- object manipulation
