motor control
refers to the ability to regulate or direct movement necessary for a perston to function indepnetly during occupation tasks
dyanamical systems theory
proposes that movement is a function of intaractsion among the neroscular sstem environment cognition and task it self they interact to influence movement
postural mechanism
include postural tone muscle tone intefration of the primitive reflexes and mass partters of movement righting reactionls equilibrium reactions protective extension and selective voluntary or intentional movement
normal postural movement
automatic involunarty movements that together provide stability and mobility during activity develop early in life
postural tone
refers to tonus in the next training and limsb must be high enough to to resist gravity thus enableing persons to be upright against gravity yet low enough to allow movement provides nessesary proximal stability
hypotonicity
a decrease in muscle tone result of a peripheral nerve injury cerebellar disease or frontal lobe damage and shock phase after stroke muscles soft and offer no resistance to passive movement
hypertonicity
spacticty refers to increase muscle tone may result fromany nerologic condition that alters upper motor neuron pathways characterized by hyperactive deep tendon reflexes occurs in antigravity of limbs
primitive reflexes
help elongate muscle groups in preparation for voluntary control
suck swallow reflex
difficulty eating involunatary protrusion and retraction o fthe tongue make it difficult to keep food and liquids int or cavit
assymetrical tonic neck reflex
may have diffeiclut maintain head in midline while moveing the eyes toward the middle f
symmetrical tonic neck reflex
cannot support the body weight on hands and knees maintain balance in quadruped and creep normally patient struggles to move from supine to sitting position because bending the increases tension in legs
tonic labrinthing reflex
extension of trunk and extremities or increased extensor postural tone flexion of trunk and extermities or increased flexor postural tone
difficulty of peforming all transitional movemtns
difficupositive supporting reflex
pressure to ball of foodt stimulise it extension in leg stimulated diffuclty donning and keeping shoes one diffucltul climbing stairs
crossed extension reflex
flexion of one lege stimulis it to extension of opposite leg
palmar grasp reflx
flexion of digist into palmar grasp stimulated by pressure in palm
plantar grasp
pressure to ball of foot response to flextion of toes
positive supporting reflex
has difficulty placing the heel on the ground for standing and alkin
crossed extension reflex
diffclty with developing a normal gait patter becaue strong extension occrs in affected leg as the unaffected leg is flexed
brunstorms stage of motor recover
no motion
reflex responses
associated reacctions
mass responses
deviation from patter
wrist stability
individual finger movements selective pattern with overlay
minimal stabilizing assist
patien can use involved upper extemit to stabilize objects being manipulated by univovle exremith
minimal active assist
patient can use the involved upper extremity to assist activel in a single part fo an activity
maximal active assist
the patient can use the involved upper extremity to assist activel in a single part of an activity
maximal active assist
the patient can use the involved arm and hand n all activities that require motor control for pushing pulling stabilize and gross grasp releas
ataxia
impaired gross coridnation and gaitn delated iniation of motor responses
adidadchokiniesea
is an inability to perform rapidly alternating movements such as forearm supination and pronation or elbow flexion ane extension
dysmetria
inability to estimate the rom necessary to reach the target of movement it is eviden when toudhin the finger to nose or placin anobject ont a table
dysserndia
decomponsition of moenemt in which voluntary movement are broken into their componets parts and ppear jerky
trmor
involuntary shaking or trmbling
rebound pheneionmom of holmes
inability to stop motion quicly to avoid striking something
nyastagmus
is an nvoluntary movement of the eyeballs in upa and down motin
dysartia faulty speech production
choerfin movemnts uncontrolled irregular purposeless quick jerk and sysrhythmical movement of variable distribution
athetioid movements
movemtns withoug stability are alow wormlike
spasms
sudden involuntary contarcions of a muscle or large groups of musles
dystonia
is faulty muscle tension or toen dystonic movements tend to involve large portions of the body and prode qrotesque posturing with bizarre writhing movements
ballisme
projectile movement rare symptom produce by contious gross abrupt contraction fo acial and proimal musculature ofht the exteremity
