Abnormal Gait & Falls Flashcards
The 3 Components of Locomotion?
- Rhythmic Control
- Stability
- Adaptation
Rhythmic Control?
Achieved via Central Pattern Generators (CPG)
- located in the spinal cord
We can do all this at the same time due to the CPG
Sensory feedback effects CPG
- something in our shoe will effect our walking
Stability?
Stability in walking is achieved through the Balance/Postural Control System
Dynamic walking requires a constant interaction between:
- Musculoskeletal System
- Nervous System
- Environment/task
A coordinated change of BOS is required to “contain” the ever moving COM/COG over a surface
Adaptation?
We have to adjust to ever-changing environmental/task demands to prevent injury
Eg) We judge how fast cars are coming & we adjust our gait to speed up if we think can make it across the street
Trendelenburg gait?
Weak gluteus medius (which stabilizes the hip)
= lack of support will show a drop of the pelvis in the opposite side
- We see it more in the gait swing
Foot drop Gait?
Occurs in 2 movements –
1st = Toe off (need to hold dorsi flexion)
- Weak tibialis causes foot to drop
2nd = Heel is put on floor
- When foot is been transferred onto the floor, weak tibialis causes foot will slap
(peripheral nerve injuries will lead to this)
Quadriceps Gait?
Quad helps extend the knee & also in stance phase to help stabilize.
If don’t have the support the knee will go into hyperextention
(this is called “Genu Recurvatum”)
Treatment:
- Increase strength of quad muscle (remedial)
- Splint (compensatory)
Genu Recurvatum?
Knee goes into hyperextension
Gluteus Maximus Lurch?
Inability to support during stance
- they will lurch forward due to no hip strength. This causes leg to lurch forward
Ataxic Gait?
Inability to judge distance (dysmetria)
- start of movement will be shaky & uncontrolled when movement is being performed
High risk for falls due to narrow BOS
- also tremors & hypertonia
Hemiplegic Gait?
We may see circumduction, & possibly foot drop, may also see Trendelenburg
Treatment:
- We work specifically on gait, but also ensure good balance strategies (hip & ankle strategies).
Treatment for Abnormal gait ( Remedial Approach)?
NDT & Bobath
= To promote going through the milestones, to try to restore the stages, to restore abnormal movement & inhibit tone
Usually we use BOTH remedial AND compensatory at the same time & slowly wean them off compensatory
Treatment for Abnormal gait (Compensatory Approach)?
GOAL = Restoring them to THEIR maximum normal
If function not restored after 6 months chances are it wont come back
We also work on strength & endurance
How to measure Treatment of Gait?
Tinetti scale
TUG
10m walk
Indoor vs outdoor
(household vs community ambulation),
Fall Facts?
Seniors who have fallen double their risk of future falls
90% of hip fractures are due to falls
40% of long-term care admissions are fall related
