manual locking knee

Question 3

K2 components

Answer 3

single axis or multiaxial foot

Question 4

K3 components

Answer 4

multiaxial foot

hydraulic & pneumatic or microprocessor knee

Question 5

K4 components

Answer 5

multiaxial foot

Microprocessor knee

Question 6

general gait characteristics

Answer 6

Decreased energy efficiency, biomechanical efficiency walking speed, stride length and cadence
Trauma pt walk faster than dysvascular
Dysvascular have reduced amount of O2
“Normal” prosthetic gait is a function of socket fit, prosthetic alignment, components and user ability

Question 7

BKA amp general gait highlights

Answer 7

MSt - pylon as close to vertical as possible

TSt - smooth progression of foot

Question 8

AKA general gait highlight

Answer 8

IC/IR - stride length decreases
MSt - weight shift over prosthetic
TSt - SLS decreases
PSw - adequate suspension
Sw - lower velocity

BKA circumduction

Answer 18

prosthetic cause - 
poor sus
too long
patient cause - 
feeling of instability
decreased knee FL during swing
