Study Notes

Physiology of Movement

Movement is achieved through contracting muscles that apply force on tendons, which, in turn, pull on bones.
Three systems are essential for movement: nervous, muscular, and skeletal.

Nervous System

The somatic nervous system of the peripheral nervous system controls voluntary muscles.
Sensory information travels to the central nervous system via the afferent pathway.
Motor information travels from the central nervous system to muscles via the efferent pathway.

Sensorimotor Function

Necessary for movement.
Includes sensory reception (receiving data from visual, auditory, olfactory, gustatory, tactile, and kinesthetic senses) and sensory perception (organizing and interpreting received data.)
Impaired sensory processing increases the risk of injury.

Sensory Disorders

Sensory disorders occur when there is insufficient or excessive sensory stimuli, disturbed sensory perception, or a sensory deficit.
Sensory deprivation is the lack of sufficient sensory stimuli.
Sensory overload is excessive stimuli, which overwhelms the brain's ability to process, respond, or ignore.

Effects of Sensory Deprivation

Perceptual disturbances, cognitive disturbances, and emotional disturbances.

Factors Influencing Sensory Status

Developmental level (elderly individuals may experience sensory decline with aging).
Personality and lifestyle (different personalities may require different levels of stimulation, and lifestyle choices influence the quantity and quality of sensory stimuli received.)
Stress and illness (illness and stress can affect the reception, transmission, and perception of sensory stimuli.)
Medications (medications that alter or depress the central nervous system can interfere with the perception of sensory stimuli. Narcotics and sedatives reduce alertness, and antipsychotics influence the perception and processing of stimuli.)
