L1 Theories Flashcards
Motor Control
the ability to regulate or direct the mechanisms essential to movement
Coordination
related to movement
Stability
related to posture
Motor Control and the CNS
how organization happens between muscles, joints into coordinated functional movements and dynamic postural adjustments
Sensory info
how info is relayed from environment and body to select and control movement
Motor control is a perception of
self, tasks, environment
Motor control theories
theoretical ideas about control of movement
motor learning theories
understanding acquisition and/or modification of learning
motor development theories
normal progression of aging on molecular, cellular, tissue, systems levels
Reflex Theory
One of the earliest theories about motor control
movement controlled by stimulus-response, movements are formed by “linking” reflexes together
reflexes are basis for movement and combine into actions that create behavior
failed to account for voluntary movements
Hierarchical Theory
nervous system is organized as top-down, skill acquisition follows the same pattern
Cortex –> Equilibrium, Bipedal function
Midbrain –> righting reactions, quadrupedal
Brainstem–> primitive, apedal
Motor Programming Theory
- Cortex generates a motor outcome, but not involved in how outcome is achieved
- Generalized motor programs and central pattern generators serve as a network to help produce an outcome
Systems Theory
Movement directed by dynamic, interacting systems
Body as a whole, which incorporates mechanical system, internal/external forces
movement emerges to control degrees of freedom
Degrees of Freedom
natural development of functional synergies via practice and experience to assist in coordination of muscles and joint movements all at once
Dynamic Action Theory
emphasizes the interaction between an individual, the environment, and the task as key factors influencing motor behavior. It considers movement as a dynamic process that emerges from the interplay of these elements
LIMITATION: no need for hierarchy
has a limitation that CNS is less emphasized
IMPLICATIONS: Interaction of multiple elements, includes emphasis on physical properties like velocity
Throwing a frisbee: the action would be influenced by the dynamics of the body, the frisbee properties, environmental conditions. The person adapts to these things to optimize the task goal
