The neurological process that organizes sensation from one's own body and from the environment and makes it possible to use this information to plan and organize behavior.
The ability to understand what needs to be done, plan how to do it, and get it done.
- A response that matches the demands of the task.
- Purposeful and goal directed result from sensory input.
- Disorganized processing of sensory information results in inadequate, excessive, or inaccurate information from muscles, tendons, and joints.
- Failure in the process of organizing information and directing an adaptive response.
Sensory integrative dysfunction (sensory processing dysfunction)
Concept of how to go about doing the task.
What are 3 patterns of dysfunctions identified with Sensory Inrtegrative Dysfunction?
- Dysfunction in praxis
- Dysfunction in sensory modulation
- Disorders of sensory discrimination
- Appear clumsy - stumble and bump into things.
- Poor placement of extremities for WB.
- Poor muscle co-contraction and holding against gravity.
- Difficulty grading movement.
- Seeks proprioceptive sensations.
Hyporesponsiveness to proprioceptive
- Overresponds to physical contact such as hugs.
- Uncomfortable running, jumping, using large movements.
- Avoids activities requiring movement of body parts: jumping, hanging from a bar.
Hyperresponsiveness to proprioceptive
- Gives information about the body positions that arise as a result of an individuals own movement.
- Develops through WB and movement.
- Critical in maturation of reflexes, particularly righting and equilibrium responses.
Purpose of the proprioceptive system
- Awareness of position and orientation in space.
- Regulation of eye position during head movement to stabilize the image.
- Influences muscle tone for postural support, primarily extensor tone.
Purpose of the vestibular system
- Alerts the person to danger.
- Gives information about the immediate surroundings.
- Guides the exploration of the environment.
- Assists in developing body sheme.
- Associates with emotions via the limbic system.
Purpose of the tactile system
Disordered tonicity of muscle.
Impairment of voluntary movement.
Involuntary, compulsive repetitive.
Partial loss of coordianated acts i.e. speech.
Slowness of movement
Disturbance of stress, pitch, rhythm of speech.
Disorder of voicing.
Excessive eye blinking and involuntary forced eye closure.
Involuntary movements of the jaw muscles, lips, and tongue.
Involntary movements of the neck muscles.
