Prosthetics and Orthotics

Question 1

K levels (meaning and levels)

Answer 1

functional ability classification through Medicare
determines what level of componentry will be used for a patient’s prosthesis

0: prosthesis will not enhance quality of life; not eligible for prosthesis

1: can complete transfers, ambulate on level surfaces, has fixed cadence, limited/unlimited household ambulator
-knee: single axis, constant friction mechanism
-foot/ankle: SACH, single axis

2: traverse low-level barriers/curbs, stairs, uneven surfaces, limited community ambulator
-knee: polycentric, constant friction mechanism
-foot/ankle: flexible-keel foot, multi-axial foot/ankle

3: variable cadence ambulator, unlimited community ambulator, traverse most environmental barriers, prosthetic use beyond simple locomotion
-knee: hydraulic/pneumatic, microprocessor, variable friction mechanism
-foot/ankle: energy storing, dynamic response foot, multi-axial foot/ankle

4: exceeds basic ambulation skills, exhibits high impact, stress, or energy levels, typical of child, athlete, or active adult
-knee: any
-foot/ankle: any
