general gait characteristics
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
BKA amp general gait highlights
MSt - pylon as close to vertical as possible
TSt - smooth progression of foot
AKA general gait highlight
IC/IR - stride length decreases MSt - weight shift over prosthetic TSt - SLS decreases PSw - adequate suspension Sw - lower velocity
BKA excessive knee EX
prosthetic cause - socket too far post/ foot too far ant heel to soft insufficient socket FL patient cause - weak muscles locking knee to prevent falling
BKA knee instability
prosthetic cause - socket to far ant/foot to far post heel to firm excessive DF patient cause - weak quads knee FL contracture
BKA hip drop
prosthetic cause -
too short
patient cause -
residual limb pain
BKA lateral thrust
narrow BoS w/ lateral thrust of socket during MSt prosthetic cause - foot too far inset lateral leaning pylon patient cause - glute med weakness knee lig insufficiency
BKA wide base gait
prosthetic cause - out set foot medial leaning pylon patient cause - insufficient weight shift hip AB tightness patient fear
BKA drop-off/knee instability
early and excessive knee FL TSt prosthetic cause - socket too far ant/foot too far post inappropriate foot choice patient cause - knee FL contracture
BKA vaulting
prosthetic cause - too long long keel socket too far post/foot too far ant patient cause - holding knee in EX for too long
BKA pistoning
prosthetic cause - socket too large not enough socks poor sus mech patient cause - volume changes not enough socks
BKA uneven step length
prosthetic cause - n/a patient cause - insufficient gait training decreased confidence
BKA circumduction
prosthetic cause - poor sus too long patient cause - feeling of instability decreased knee FL during swing
AKA terminal impact
forceful and excessive knee EX prosthetic cause - inadequate knee friction patient cause - fear of knee giving away forceful hip FL
AKA foot slap
prosthetic cause -
PF bumper too soft
patient cause -
increased hip EX force at IC
AKA knee instability
prosthetic cause - knee axis too far ant socket too far post lack of socket FL patient cause - inadequate hip EX ROM hip FL contracture
AKA lateral trunk bend
prosthetic cause - socket too AB prosthesis too short medial socket wall too high patient cause - pain glute med weak decreased balance ADD roll
AKA AB gait
prosthetic cause - foot/leg too far outset prosthesis too long medial socket wall too high lateral wall not AD enough patient cause - AB contracture lat-distal Residual limb pain decreased balance ADD roll
AKA excessive trunk EX
prosthetic cause - increase socket EX patient cause - weak hip EX weak ABs hip FL contracture
AKA Drop off
sudden and excessive knee FL prosthetic cause - short toe lever socket too posterior patient cause - n/a
AKA excessive heel rise
prosthetic cause -
insufficient knee friction
patient cause -
forceful hip FL
AKA circumduciton
prosthetic cause - prosthesis too long inadequate sus excessive knee friction medial wall too high patient cause - hip FL weakness hip AB contacture fear
AKA vaulting
prosthetic cause - prosthesis too long inadequate sus excessive knee friction patient cause - hip FL weakness hip AB contracture fear
AKA medial whip
medially directed motion of the prosthesis (heel) prosthetic cause - external rotation of knee component improper alignment patient cause - improper donning
AKA lateral whip
Laterally directed whipping motion of the prosthesis (heel) prosthetic causes- internal rotation improper alignment of knee bolt user improper donning
