MT: TF Prosthetic Gait Deviation Flashcards
1
Q
Why is uneven arm swing a problem?
A
- Goal of arm swing: minimize energy expenditure while maximizing stability and mobility
- what does arm swing do: reduces angular momentum of the body, improve stbaility and energy efficiency
2
Q
Uneven arm swing prosthetic causes
A
- poor socket fit
- lack of suspension (fear)
3
Q
Uneven arm swing patient causes
A
- fear
- poor balance
- habit
- lack of proper training
4
Q
Initial Contact Gait Deviation
A
- knee instability (sagittal)
- step length asymmetry
- foot slap
5
Q
Knee instability prosthetic causes
A
- knee to anterior
- insufficient socket flextion (for hip ext strength)
- too firm/high heel/shoe
6
Q
Knee instability patient causes
A
- weak hip extensors
- short residual limb
7
Q
Step length asymmetry prosthetic causes
shortened prosthetic step
A
- painful socket
- too short toe lever on the foot
8
Q
Step length asymmetry patient causes
shortened prosthetic step
A
- lack of confidence in prosthesis
- gait habit
9
Q
Foot slap prosthetic causes
A
- too soft a heel cushion or plantarflexion bumper of foot
10
Q
Foot slap patient causes
A
- forced heel compression to ensure knee stability
- habit
11
Q
Loading Response Gait Deviation
A
- external rotation of foot
12
Q
External Rotation of Foot Prosthetic Causes
A
- heel too firm
- excessive toe out
- poorly fitting socket
13
Q
External Roation of foot Patient Causes
A
- too tight shoe
- too hard heel of shoe
- incorrectly donned prosthesis
- poor muscle control
14
Q
Midstance Gait Deviations
A
- Abducted Gait
- lateral trunk bend
*
15
Q
Abducted Gait Prosthetic Causes
A
- medial proximal socket pressure
- lateral distal femur pressure
- poorly contoured lateral wall
- insufficient socket adduction during bench alignment
