Lesson 1 Flashcards
Motor control:
study of the nature of movement and how movement is controlled
Movement emerges from interaction among what three elements?
who (individual)
what (task)
where (environment)
What is perception?
the integration of sensory input into meaningful information, including proprioception, mass, vision
What is cognition?
is an essential element of movement to achieve a specific goal or intent
What does the cognitive process involve?
Attention Emotional aspects Motivation Planning Problem solving
What determines the nature of motor control?
A synthesis of information from action, perception and cognition
How are tasks categorized?
stability
mobility
manipulation
Stability tasks:
are performed with a nonmoving base of support
Mobility tasks:
are performed with a moving BOS
Open movement tasks:
a constantly changing and unpredictable environment
Closed tasks:
performed in relatively fixed or predictable situation.
Regulatory environment:
shapes the movement, such as type of the surface on the floor
Nonregulatory environment:
features of environment may influence performance but movement does not have to be dictated by these features, e.g., distraction while driving
Ecological theory:
Movement is controlled by the information in our environment that is detected by our motor systems
Hierarchical theory:
Higher centers of the nervous system are in control of the lower centers.
Motor program theory:
Control of movement is managed by a motor program that organizes, initiates, and carries out intended action
Reflex theory:
Reflexes were the building block of complex behavior
Systems theory:
Movement is controlled through many interacting systems including internal and external forces acting on the body
Recovery:
To achieve function through original processes or using mechanisms previously used, e.g.
CIMT following stroke
Compensation:
To substitute for impairments using assistive device/atypical motor patterns, e.g.
less impaired hand to perform tasks
