-
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.
Sensory integration
-
The ability to understand what needs to be done, plan how to do it, and get it done.
Praxis
-
- A response that matches the demands of the task.
- Purposeful and goal directed result from sensory input.
Adaptive response
-
- 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)
-
Ideation
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.
Dystonia
-
Impairment of voluntary movement.
Dyskenesia
-
Involuntary, compulsive repetitive.
Tics
-
Partial loss of coordianated acts i.e. speech.
Apraxia
-
Slowness of movement
Bradykinesia
-
Disturbance of stress, pitch, rhythm of speech.
Dysprosody
-
Disorder of voicing.
Dysphonia
-
Excessive eye blinking and involuntary forced eye closure.
Blepharospasm
-
Involuntary movements of the jaw muscles, lips, and tongue.
Oromandibular dystonia
-
Involntary movements of the neck muscles.
Torticollis
