Prosthetic
KNOW YOUR ACTIVITY LEVEL :
Level One(K1)
The patient has the ability or potential to use a prosthesis for transfers or ambulation
on level surfaces at fixed cadence. This is typical of a household ambulator or a
person who only walks about in their own home.
Level Two(K2)
The patient has the ability or potential for ambulation with the ability to traverse lowlevel environmental barriers such as curbs, stairs or uneven surfaces. This is typical
of the limited community ambulator.
Level Three(K3)
The patient has the ability or potential for ambulation with variable cadence. A
person at level 3 is typically a community ambulator who also has the ability to
traverse most environmental barriers and may have vocational, therapeutic or
exercise activity that demands prosthetic use beyond simple locomotion.
Level Four(K4)
The patient has the ability or potential for prosthetic ambulation that exceeds basic
ambulation skills, exhibiting high impact, stress or energy levels. This is typical of the
prosthetic demands of the child, active adult or athlete.
