Pathological Gait 1 Flashcards
What is pathological gait?
Impairment of an individuals ability to walk
What is pathological gait associated with?
Altered mechanics and reduced efficiency
What are the mechanisms that contribute to pathological gait?
Impaired motor control
Abnormal ROM
Impaired sensation
Pain
What are the impairments of peripheral origin that contribute to pathological gait in motor control impairments?
Weakness
What are the impairments of central origin that contribute to pathological gait in motor control impairments?
Hypertonicity
Lack of selective control
Apraxia
Ataxia
Rigidity
What is elastic contracture?
From inactivity or increased stiffness of bulky tissues (yield to forceful stretch)
What is a rigid contracture?
Muscle shortness (resistant to considerable force)
What may enhance a rigid contracture?
Scarring from trauma or surgery
How could impaired sensation contribute to pathological gait?
Inconsistent gait pattern
Prevents prompt substitution
Includes perceptual deficits
What might pain contribute to pathological gait?
Slowed walking speed
Shortened stance phase on painful limb
Tendency to stiffen limb to avoid joint excursion
Absence of forceful foot contact or push off
What are primary deviations?
Gait deviation occurring as a direct result of an associated impairment
What are secondary deviations?
Gait deviation occurring as a secondary consequence of a different impairment (regional interdependence)
How is pathological gait addressed clinically?
Problem identification
Cause identification
Treatment
