Motor control motor learning

Motor control is....

• Learning a new motor skill

• Re-acquiring a motor skill after neuro injury

• The ability to regulate and direct the neural and biomechanical mechanisms essential for movement

• None of these

A discrete task:

• Has a recognizable beginning and end

• Is arbitrarily ended by the performer

• Is performed with a non-moving base of support

• Requires performers to constantly adapt to an unpredictable environment

Which of the following is a non-regulatory attribute of the task environment?

• The weight of an item during a reaching task

• The terrain of a walking task (sidewalk vs grassy hill)

• The surface of a sit-to-stand transfer (therapy mat vs low height recliner)

• Background noise and distractions during a mobility task

Non-declarative or implicit learning:

• Involves factual knowledge

• Is expressed primarily through the performance of motor skills

• Relies heavily on higher cognitive processes

• Does not require a lot of repetition to acquire

When a patient learns to avoid bearing weight through the hemi-paretic lower extremity to decrease their fall risk, this may be an example of:

• Habituation

• Classical conditioning

• Operant conditioning

• Procedural learning

A patient working on gait training is engaged in a cognitive dual task of subtracting backward from 100 by 7's. This intervention is most appropriate for a patient in which stage of learning according to Fitts and Posner's three-stage model?

• Cognitive

• Associative

• Autonomous

• Acquisition

Which of the following strategies may result in decreased early performance but the long-term retention and transfer of a motor skill?

• Constant practice

• Blocked practice

• Random practice

• Guided learning

Which of the following is true regarding provision of feedback?

• Feedback should be provided immediately and after every trial

• The time between completion of the task and provision of feedback should include other different tasks

• Feedback should not be constant and should be gradually phased out as the patient progresses through the stages of motor learning

• Intrinsic feedback supplements extrinsic feedback
