Introduction to Motor Control Flashcards
What is human movement science?
Multidisciplinary science that shares an interest in understanding how movements develop in the young, and are learned by and change in young and old alike.
Understanding underlying control mechanisms that are necessary for skilled performance.
Although many sciences target areas of study in human movement, a behavioral focus leads to the study of motor development, motor control, and motor learning
How do we focus our study for human movement science?
Focus our study on normal movement of healthy young adults (they are more accessible). We can examine changes across the life span AND altered motor systems due to CNS or orthopedic pathology.
By making comparisons we can generate info on how and why a person of a given age or with a given pathology is likely to present.
What is motor control?
Ability to regulate of direct the mechanisms essential to movement
How is movement classified?
Movement that is “developmentally defined”
Movement that is “learned”
T/F: In most movements, you will find elements of our development influencing how the skill is learned, mastered, and performed?
True
T/F: movement classifications have to be exclusive?
False: Don’t have to be exclusive.
Our bodies are developed to be bi pedal walkers (defined) however walking is also a skill that takes practice (learned)
Movement emerges from the interaction of these 3 factors.
The individual
The task
The environment
What are factors within the individual that constrain movement?
Action: activity selected
Perception: peripheral and higher level processing that provide info about movement, how you evaluate that you are accomplishing what you intended
Cognition: critical for meaning and intention of movements, why you choose a specific action
What are environmental constraints on movement?
Regulatory features: directly influence movement
Non-regulatory features: can shape a movement but may have no influence on the movement
How are tasks classified?
Discrete vs. serial vs. continuous
Stability vs. mobility
Open vs. closed
What are discrete, serial, continuous tasks?
Discrete has defined beginning and end.
Serial is series of discrete movements performed in order.
Continuous are longer and require frequent update and evaluation of performance.
What are open and closed tasks?
Open: changing environments
Closed: predictable environments
What must we keep in mind when deciding how a skill should be practiced?
Be mindful of goal of movement (task), ability of client (individual), and the environment when deciding whether a skill should be practiced as discrete, serial, or continuous
What is important to think about when observing and understanding human movement?
It is very complex. Takes great deal of knowledge and problem solving, along with clinical experience to know how to be good “coaches” for our patients
What are some histories of motor control?
Leonardo da vinci
Descartes
Muybridge
