Technical Data.
Activity Level 1
Has the ability or potential to use a prosthesis for transfers or ambulation on level surfaces at fixed
cadence. Typical of the limited and unlimited household ambulator.
Activity Level 2
Has the ability or potential for ambulation with the ability to traverse low-level environmental barriers
such as curbs, stairs, or uneven surfaces. Typical of the limited community ambulator.
Activity Level 3
Has the ability or potential for ambulation with variable cadence. Typical of the community ambulator
who has the ability to traverse most environmental barriers and may have vocational, therapeutic, or
exercise activity that demands prosthetic utilization beyond simple locomotion.
Activity Level 4
Has the ability or potential for prosthetic ambulation that exceeds basic ambulation skills, exhibiting
high impact, stress, or energy levels. Typical of the prosthetic demands of the child, active adult, or
athlete..
