Open movement tasks are best described as
relatively stereotyped tasks with little variation.
tasks that are performed prior to closed movement tasks.
tasks that require the performer to adapt his or her behavior.
predictable tasks that serve as a progression for movement retraining.
A theory of motor control is:
a group of accumulated facts about motor control.
a group of abstract ideas about the control of movement.
a group of observations about the control of movement.
a group of accumulated statements about motor control.
What is the role of central pattern generators in the control of movement?
They are thought to generate complex movement in the absence of reflex activity.
They replace the concept of the importance of sensory input in controlling movement.
They are the sole determinant of motor action.
They account for both musculoskeletal and environmental variables in achieving movement control.
According to Shumway-Cook and Woollacott, movement emerges from an
interaction between the individual and the task.
interaction between the visual, vestibular, and somatosensory systems.
interaction between the individual, the task, and the environment.
interaction between the nervous and musculoskeletal systems.
A patient is learning to redefine her limits of stability in standing to distribute her weight evenly on both sides without falling to one side after stroke. This is an example of:
nonassociative learning.
explicit learning.
associative learning.
declarative learning.
The assumptions related to the task-oriented approach suggest that when retraining movement control:
it is important that the intervention be directed at modifying the reflexes that control movement.
patterns.
The therapist should focus on identifying the presence or absence of abnormal reflexes controlling movement.
it is important that the patient regain normal patterns of movement to facilitate functional recovery.
it is fundamental to focus on identifiable functional tasks rather than on movement patterns
Sensitivity is:
The degree to which an instrument behaves as hypothesized.
The ability of an instrument to rule out a disorder when it is not present.
.
The degree to which a diagnostic test detects a disorder when it is present.
The ability of an instrument to agree with other instruments that are measuring the same thing
Which of the following brain centers contribute to the regulation of postural tone?
Brainstem nuclei
Vestibular nuclei
Frontal cortex
Pre-motor cortex
Research on the anticipatory aspects of postural control has revealed:
that postural muscle activation patterns could be divided into two phases, a feedforward and a feedback component.
that postural muscle activation patterns occur as the result of one systematic response.
that anticipation has no application to scaling the amplitude of postural responses.
that anticipatory postural responses are isolated to tasks that are performed in standing.
When discussing knowledge of results (KR), which of the following statements would be true?
Knowledge of results is an essential form of intrinsic feedback.
Knowledge of results should be given in 100% of trials.
The most effective summary KR length is reported to be five trials.
Immediate KR enhances learning of a motor skill.
In older adults, declines in visual function would most likely relate to:
decreased sway excursion in quiet stance.
increased stability when walking in low light environments.
increased sway excursion in quiet stance.
decreased reliance on other systems to maintain postural control.
A 75-year-old female falls while carrying a large bag of groceries up four stairs. This fall most likely is attributed to a:
diminished vestibular function.
weakness of the hamstrings muscles.
diminished anticipatory postural responses.
weakness of the anterior tibialis muscles.
How is the muscle response organized in some older adults when responding to a perturbation?
The muscle response organization is disrupted with distal muscles being activated before proximal muscles.
The muscle response organization is disrupted with proximal muscles being activated before distal muscles.
The muscle response organization is more likely to involve ankle movements rather than hip movements.
The muscle response organization is more likely to demonstrate hypermobility at certain joints.
What does research suggest is the percentage contribution of genetic factors to longevity?
20 percent
40 percent
60 percent
80 percent
An 85-year-old retired male attorney rides his road bike 6 days weekly a minimum of 7 miles in 50 minutes. Using Spirduso's continuum of function, identify the group to which this client would best fit.
Physically elite
Physically fit
Physically independent
Physically frail
A 72-year-old female is independent in basic and instrumental ADLs and is able to ambulate in her home and community using a cane. Using Spirduso's continuum of function, identify the group to which this client would best fit.
Physically elite
Physically fit
Physically independent
Physically frail
One hypothesized role of the association cortices is to:
link information from the cerebellum and the basal ganglia.
link information from several senses.
combine reflex information from the brainstem systems.
focus on information coming from one part of the body.
