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.

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.

Synergistic organization refers to the coordination and cooperation of different muscles and body parts to perform a movement or task efficiently. It involves the integration of various muscles, joints, and sensory inputs to produce a smooth and coordinated movement. This concept emphasizes the importance of working together and synchronizing the efforts of different body parts to achieve optimal performance and minimize resistance to passive elongation.

The given answer correctly defines motor program as a set of commands that result in the production of a coordinated movement sequence. It implies that a motor program is a predetermined set of instructions that the brain sends to the muscles to carry out a specific movement. These commands ensure that the movement is coordinated and executed in a sequence. The answer also highlights the key aspect of motor program, which is the production of coordinated movement.

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.

Arousal refers to the overall alertness of the central nervous system. It is the state of being awake and responsive to stimuli in the environment. Arousal is important for various cognitive processes such as perception, attention, and cognition. It influences our ability to be aware of and process sensory information, as well as our level of consciousness. Arousal is necessary for maintaining an optimal level of cognitive functioning and plays a crucial role in regulating our sleep-wake cycle.

The given answer "resistance of a muscle to passive elongation or stretch" accurately describes muscle tone. Muscle tone refers to the state of tension in a muscle at rest. It is the resistance that a muscle exhibits when it is passively stretched or elongated. This resistance is present even when there is no active contraction of the muscle. Therefore, the answer correctly identifies the characteristic of muscle tone being described in the given options.

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.

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.

Motor control refers to the complex interactions between various body systems that work together to produce coordinated movement. It involves the integration and interpretation of sensory information, the selection of appropriate motor programs, and the execution of movement sequences. These interactions can involve the nervous system, muscles, bones, and other physiological processes.

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.

The correct answer is "association cortex of basal ganglia, organizes sensory information and motor plan." The association cortex of the basal ganglia plays a crucial role in motor control by organizing sensory information and developing motor plans. It helps in integrating sensory inputs from different areas of the brain and coordinating them with motor commands. This process allows for smooth and coordinated movements. The involvement of the basal ganglia in motor control is essential for maintaining balance, posture, and executing complex motor tasks.
