Correct Answer
D. Storage of motor programs, how the movement felt, components and outcomeExplanation
The correct answer is "storage of motor programs, how the movement felt, components and outcome". This answer accurately describes motor memory as the storage of motor programs, which includes information about how the movement felt, the components involved in the movement, and the outcome of the movement. Motor memory allows for the formation of a motor plan, which is a set of commands that result in the production of a coordinated movement sequence. This coordinated movement involves actions at two or more joints and can be seen as spontaneous stereotypical patterns of motor activity associated with various stimuli.Rate this question:

Factors influencing motor control include all but......
- A.
Coordination
- B.
Perception
- C.
Cognition
- D.
Arousal
- E.
Sensation
Correct Answer
A. CoordinationExplanation
Motor control is the ability to regulate and coordinate the movements of the body. Factors that influence motor control include perception, cognition, arousal, and sensation. However, coordination is not a factor that influences motor control. Coordination refers to the ability to integrate and synchronize different movements of the body parts. While coordination is important for smooth and efficient movement, it is not a direct factor that influences motor control.Rate this question:

Decreased Perception may result in the patient being unable to complete simple tasks safely and independently and may make the same mistake over and over.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Decreased perception refers to a decline in the ability to interpret and understand sensory information correctly. This can include visual, auditory, or tactile perception. When a patient has decreased perception, they may struggle to accurately perceive their surroundings and may have difficulty completing simple tasks safely and independently. Additionally, they may repeat the same mistake multiple times due to their inability to perceive the correct information. Therefore, the statement that decreased perception may result in the patient being unable to complete simple tasks safely and independently and making the same mistake over and over is true.Rate this question:

Correct Answer
C. ToneExplanation
The Modified Ashworth Scale is a tool used to assess muscle tone in individuals with neurological conditions. It measures the resistance felt by the examiner when passively moving a joint through its range of motion. The scale categorizes tone as either normal, mild, moderate, or severe. Tone refers to the level of tension or resistance present in a muscle at rest. It can be affected by various factors such as muscle spasticity or rigidity. Assessing tone is important in understanding and managing movement patterns, coordination, and functional abilities in individuals with neurological impairments.Rate this question:

- A.
True
- B.
False
Correct Answer
A. TrueExplanation
On the Ashworth scale, which is used to measure tone, a score of 2 is considered normal. This means that a person's muscle tone is within the expected range and there is no abnormal increase or decrease in muscle resistance. Therefore, the statement "2 is normal" is correct.Rate this question:

Stability, mobility, controlled mobility, skill
- B.
Strengthening, improve coordination, task modification, and decrease in spasticity
- C.
Mobility, stability, controlled mobility, skill
- D.
Improve coordination, strengthen, task modification and decrease spasticity
Correct Answer
C. Mobility, stability, controlled mobility, skillExplanation
The correct answer is "mobility, stability, controlled mobility, skill." This order of control during functional activities suggests that mobility is the initial stage, where the individual gains the ability to move freely. Stability comes next, where they develop the ability to maintain a stable position. Controlled mobility follows, where they learn to control their movements while maintaining stability. Finally, skill is the last stage, where they acquire specific skills and coordination for more complex tasks.Rate this question:
