Exam 5: PNS vs CNS, Motor Assessment, Learning and Sensorimotor Approaches Flashcards
Hand Therapy, Splinting, PAMs, PNS vs. CNS deficits, Theorists of Functional Movement
sensori =
input through the senses
- used with those with CNS damage
motor =
muscle movement
- used with those with CNS damage
PNS vs. cns damage
- problem with the receptors (sensory or motor), muscle quality and function (muscular dystrophy), or tissue (tendons, joints, cartilage, ligaments, etc)
- does not DIRECTLY involve the BRAIN
- brain may make errors based on faulty input
CNS vs. pns damage
- damage to the BRAIN or SPINAL CORD, but impacts peripheral function
- causes changes to the peripheral tissue and structures
- causes changes in muscle tone and coordination
- causes recurrence of primitive reflexes
- because brain is involved, can also have cognitive, perceptual, and motor planning deficits along with weakness and motor change
FOR for PNS damage
- BIOMECHANICAL for REMEDIATION
or…. REHABILITATIVE for COMPENSATION - prognosis depends on amount and cause of dysfunction
FOR for CNS damage
- SENSORIMOTOR for REMEDIATION
or…. REHABILITATIVE for COMPENSATION - prognosis depends on the amount of the brain impacted and where the areas of damage are
goals of sensorimotor approaches (5)
- REDUCE abnormal changes in movement patterns
- NORMALIZE muscle tone
- FACILITATE symmetrical posture
- IMPROVE balance
- uses neuroplasticity
motor control def. + associated factors (5)
the ability to regulate or direct movement
- perception (making sense of input)
- motor planning (processing input)
- motor execution (carrying out movement)
- feedback (internal and external)
- biomechanics (relationship of muscles and joints to one another)
postural tone def.
muscle tension in the neck, trunk, and limbs
- must be HIGH enough to resist gravity
- must be LOW enough to allow movement
normal postural tone allows: (3)
- automatic and continuous adjustments
- proximal stability allowing for distal mobility
- base for voluntary, selective movements
postural mechanisms def. + associated factors (5)
automatic, involuntary movements that together provide stability and mobility during activity
- postural tone
- muscle tone
- reflexes
- automatic reactions
- coordination
causes of hypotonicity/ low muscle tone
- peripheral nerve injury
- cerebellar disease
- frontal lobe damage
- neuromuscular junction impairment
shock phase of stroke or SCI - often turns into hypertonicity eventually
characteristics of hypotonicity/ low muscle tone
- muscle soft, mushy
- no resistance to PROM
- limb heavy
- limb must be protected
- hypermobile joints
- easily fatigued
- can’t maintain positions
causes of hypertonicity/ increased muscle tone
- any condition impacting upper motor neuron pathways
characteristics of hypertonicity/ increased muscle tone
- hyperactive stretch reflex
- greater than normal resistance to PROM
- clonus: quick, alternating agonist/ antagonist contractions
- decreased mobility
- pain or stiffness
