The goal of occupational therapy is to enable children with cerebral palsy to participate in activities of daily living that are meaningful for them. Occupational Therapy can provide children with positive, fun activities to enhance their cognitive, physical, fine motor skills and increase their self esteem and sense of accomplishment. Occupational Therapist also prescribes orthosis, seating equipment and wheelchairs according to individual needs. Children with cerebral palsy also have Sensory Integration dysfunction. Sensory Integration is the ability to organise and process sensory information from our body as well as from the environment, to perform goal oriented behaviour. Children with cerebral palsy may experience decreased sensation or a limited understanding of how the brain interprets what it sees.

To improve the services provided, Sensory Integration unit was set up to provide sensory-perceptual-motor (SPM) training for children with cerebral palsy who have sensory integration dysfunction. This sensory-perceptual-motor training teach the children to process the sensory inputs and produce organized behaviour which will improve their daily functional abilities.

 

WHAT IS SENSORY INTEGRATION?
Sensory integration is about how our brain receives and processes sensory information so that we can do the things we need to do in our everyday life. Jean Ayres defined sensory integration as: “The neurological process that organises sensation from one’s own body and from the environment and makes it possible to use the body effectively with the environment” (1972)

 

THE 8 SENSES

In sensory integration we are interested in all 8 senses. You can probably immediately think of 5 only – seeing, hearing, tasting, smelling and the sense of touch. The other three are proprioception, vestibular and interoception, these are defined below.

 

PROPRIOCEPTION

Our muscles and joints have tiny sensory receptors that tell our brain where our body parts are. When you put a spoon to your mouth, you don’t need to look at the spoon to see where it is or feel for your mouth to know where to place the spoon; you know where your hand is in relation to your mouth. Your brain then uses this information to plan movements so that you can coordinate your body.VESTIBULAR – In our inner ear we have small, fluid filled canals, the fluid in these canals moves every time we move our head. Receptors in these canals pick up the direction of movement and send this information on to our brain. So we know if we are moving forwards, backwards, side to side, tilting our head, turning round or moving up and down. Once again, our brain uses this information to plan for movements and help us maintain our balance.

 

INTEROCEPTION

Interoception is how our body tells our brain what is going on inside our body, when we are hungry or feel full, when our heart is beating fast or when we have that sensation of butterflies in the stomach. Jean Ayres was particularly interested in the interaction between and development of the vestibular, proprioception, touch, vision, and hearing. She saw these as important in supporting our ability to use our body, concentrate, develop self-esteem and confidence as well as having self-control and academic skills. We continue to see the link between poorly developed senses and these abilities both in research and in practice.

 

SENSORY INTEGRATION PROBLEMS

Recently Parham and Mailloux (2015) identified four categories of sensory integration problems
1. Problems With Sensory Modulation
Problems with sensory modulation occur when our brain either over responds to, or under responds to sensory information. Problems with modulation can cause the  person to become anxious, fearful, angry and frustrated.

2. Sensory Discrimination and Perceptual Problems
This is when the brain has difficulties with making sense of the sensory information it receives. The person then struggles to interpret subtle differences in the sense.

3. Vestibular-Bilateral Functional Problems
These problems are a result of problems with our vestibular sense and can result in poor balance and difficulties with coordinating two sides of the body.
