Cerebral Palsy Cerebral palsy results from damage to the structures of the cerebral cortex, cerebellum, and spinal cord. It is characterized by atypical muscle tone and poor coordination among muscle groups which results in postural abnormalities and structural deformities.
Cerebral Palsy • Muscle Tone Abnormalities • Hypotonia • Hypertonia • Dystonia • Area of Involvement • Hemiplegia • Paraplegia • Quadriplegia
Two Approaches • Neurodevelopment treatment (NDT) (Campbell 1995; Bobath, 1980) • Sensory Integration (Ayres, 1979)
Important Factors of NDT • Tone • Quality of movement • contractures • range of motion • Quantity of movement
Abnormal movement patterns caused by problems in muscle tone
Support for Individualswith Cerebral Palsy • Goal: Normalization of muscle tone through using proper positioning and handling techniques. • Use adaptive equipment to normalize tone and to enable more movement and participation. • Encourage and teach normal movement patterns.
Muscle Tone and Posture Posture is the extent to which the body is maintained in alignment with a variety of positions.
Key Points of Control • Head and neck • Shoulders and shoulder girdle • Hips and pelvis
Considerations for Personswith Physical Disabilities • Teach normal movement patterns • Modify environment to increase access • Use alternative motor movement • Adapt materials or use devices
Movement Develops… Cephalocaudally
Movement Develops… Proximal to Distal
Reflex Inhibition • Startle Reflex • ATNR (Asymmetrical Tonic Neck Reflex) • STNR (Symmetrical Tonic Neck Reflex) • Equilibrium and Righting Reactions
Increase Access to Materials • Create Boundaries • Stabilize Objects • Use Grasping Aids • Use Manipulation Aids
Sensory Integration • Many people with Autism and MR have atypical sensorimotor responses. • Approach seeks to inhibit sensitivity— examples—brushing for tactile defensiveness, deep pressure. • Approach seeks to integrate sensorimotor skills through vestibular integration—example—slow spinning. • THERE IS VERY LITTLE RESEACH ON THE EFFACY ON SENSORY INTEGRATION—BE A CAREFUL CONSUMER.
