Accurate Solutions.
Motor Skill correct answers A learned sequence of movements that combine to produce a
smooth, efficient action in order to master a particular task.
The development occurs in the motor cortex, the region of the cerebral cortex that controls
voluntary muscle groups.
Motor Development correct answers The study of changes in human motor behavior over the
lifespan, the process that underlie these changes, and the factors that affect them.
All periods of development are valued equally.
Dynamic, nonlinear process with periods of stability and instability.
Influenced by intrinsic and extrinsic factors.
Important as a PTA to understand this process for proper assessment and intervention of
impairment/functional challenges encountered at any age stage.
Dynamic System Theory correct answers An individual uses all possible strategies to accomplish
a task and as physiological systems are modified, the motor behavior changes.
A more holistic approach; process rather than product; self-organizing process.
An interactive model where both intrinsic and extrinsic variables impact motor skill development
and acquisition.
Each subsystem develops at its own rate & may be a strength or constraint for development of
movement.
Dynamic interaction among the subsystems create modifications in motor behavior (i.e.
Musculoskeletal, Neuromuscular, Cardiovascular, Pulmonary and Cognitive systems).
Motor Control correct answers Study of how the CNS regulates the musculoskeletal system and
environment in regard to movement for the attainment of a specific task.
3 important elements of motor control.
1.Neural circuit—underlies the processing of input/output.
2.Motor plan—effector of output of the neural circuit.
3.The environment in which movement occurs—shapes the play between the neural circuit & the
motor plan.
Stresses task specific learning - all movements are goal oriented.
, Takes into account both neuromuscular control processes & environmental constraints.
Motor Control Strategies correct answers Motor Program.
Motor Plan.
Feedback.
Motor Skill Acquisition.
CNS Recovery.
Feed Forward.
Motor Program correct answers A set of pre-structured muscle commands that end up producing
coordinated movement / learned task / carried out without influence of peripheral feedback.
Motor Plan correct answers Overall strategy for movement.
Feedback correct answers Afferent information sent by sensory receptors to control centers with
constant updates that allow for corrections shaping the ongoing movement & allows motor
responses to be adapted to the demands of the environment.
Motor Skill Acquisition correct answers Behavior is organized to achieve a goal directed task
with active problem solving needed for the development of the motor program, plan, and
learning & is adaptive to the specific demands of the environment.
CNS Recovery correct answers Reorganization is dependent on experience - practice is required
to regain lost skills, & ability to retain & generalize re-learned skill to other similar tasks or to
apply in other environmental contexts.
Feed Forward correct answers Prepares the system in anticipation of responses required for
movement and adjusts the system for incoming sensory feedback for future movements.
- Anticipatory (feed-forward) postural adjustments used by children with cerebral palsy and
typically developing children to counteract self-generated motions that disturb balance.
Motor Learning correct answers "The study of how individuals acquire, modify, and retain motor
memories so they can be used, reused, and modified during functional activities".
Four major points of motor learning.
1.Learning is a process of acquiring the capability for skilled action.
2.Learning results from practice or experience.
3.Learning can't be measured directly.
4.Learning produces relatively permanent changes in behavior.
