Why do we analyze gait?
- Identify deviations in gait in order to address with intervention.
- Determine functional ambulation capability across variety of environments.
- Assess balance, safety, endurance, energy expenditure as it relates to walking.
- Determine need for assistive devices/orthotics.
- Evaluate the effectiveness of your interventions; describe how your interventions impacted gait.
The goal of analyzing gait is to identify _________ and design appropriate __________ to treat impairments (function/participation limitations.
- deviations
- interventions
What are some abnormalities that can cause gait deviations?
- Pain
- Joint and/or muscle ROM limitation
- Muscular weakness/paralysis
- Impaired motor control
- Neurological involvement (UMN or LMN)
- Impaired balance
- Leg length discrepancy
- A single impairment may result in a number of ___________.
- A single deviation may be caused by multiple __________.
- Deviations are often ____________ to make gait more effecient.
- deviations
- impairments
- compensations
Ways to make analyzing gait easier?
- Analyze from bottom-up/top-down
- Work in segments
- Identify reference limb
- Select a plane to start in (look at all)
- Work in phases
Can deviations in one joint be due to impairments/deviations in other joints above/below it?
Yes
-not just weak tib anterior could cause toe drag
What is an Antalgic Gait?
Compensatory gait adopted to remove or decrease the discomfort caused by pain in the lower leg, pelvis, lumbar spine.
What are the characteristic features of an Antalgic Gait?
- Decreased stance phase duration on affected limb.
- Lack of weight shift laterally over stance limb to keep weight off the involved limb.
- Decrease in stance phase in affected side will result in decrease in swing phase of uninvolved limb and thus shortened step length on uninvolved side.
