Exam 3 Week 12 ppt 14 Gait and Apraxia Flashcards
Gait is (voluntary/ involuntary)
a voluntarily deployed movement
Gait is (learned/instinctual)
instinctual
When are stepping patterns present?
~present at birth
- *Operational synergies contained in spinal cord in the form of Central pattern generators (CPGs)
- *what the person does consciously is simply to Modify these organized synergies based upon environmental demands
Gait is a function resulting from integration of
control of: ~cortical areas ~cerebellum ~basal ganglia ~spinal cord
abnormalities in gait caused by
~can occur with dysfunction of a variety of nervous system structures
~gait disturbances can be caused by a variety of non-neural causes
Types of Gait Disorders
~Ataxic ~Tabetic ~Hemiplegic ~Diplegic ~Parkinsonain ~Dyskinetic
Types of apraxia
~ideational
~ideomotor
~kinetic
~oral
Ataxic Gait
~Wide base of support
~irregular/erratic weight shifts and velocity
Tabetic Gait
Also called sensory ataxia ~Wide base of support ~high stepping (steppage) ~drop foot ~irregular/erratic cadence ~ataxia
Hemiplegic Gait
Also called spastic gait ~Slow, stiff leg ~circumduction ~foot drop ~flexed arm posture with no swing
Diplegic Gait
Also called spastic gait ~faster ~ataxic ~stiff leg, circumducted, adducted ~hip & knees flexes ~plantar flexion ~foot drop ~flexed arm posture with no swing
Parkinsonain Gait
~Slow, stiff, shuffling gait
~no arm swing
~can be a quick, short stepping (festinating gait)
Dyskinetic Gait
~Rapid, fragmented movement intrusions
~ataxia
~dance like movement
Ataxic Gait is caused by
~Cerebellar in origin
Tabetic Gait is caused by
~due to Peripheral nerve damage
