Brief Summary

Standardized outcome measures can be used to document patient health outcomes and improve treatment of those requiring prosthetic and orthotic (O\&P) services. Though numerous instruments have been developed, existing measures of O\&P outcomes have serious shortcomings including limited evidence that the scores are responsive to clinical changes. The investigators are developing the Prosthetic Limb Users Survey-Mobility (PLUS-M) using modern measurement methods to be a brief, precise and flexible measure of mobility for persons with lower limb amputation (LLA). The investigators propose the following objectives to achieve this goal. Key objective 1: develop a measure (item bank) for measuring mobility in persons with lower limb loss Key objective 2: study health profiles of lower limb prosthetic users Key objective 3: validate the measure in a longitudinal study of people receiving replacement prosthetic limbs Key objective 4: study longitudinal health patterns of persons with lower limb amputation

    Single time point

  • Patient Reported Outcomes Measurement Information Systems (PROMIS) brief profile

    Single time point

  • Activities Specific Balance Confidence Scale (ABC)

    Single time point

Study Arms (1)

Persons with lower limb amputation

Persons with amputation below the hip and at or above the ankle

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Persons with lower limb amputation living in the United States

You may qualify if:

  • (1) be 18 years of age or older; (2) have a unilateral or bilateral amputation of the lower limb between the hip and knee or between the knee and ankle; (3) own and use a lower limb prostheses; (4) and be able to read, write, and understand spoken English.

You may not qualify if:

  • (1) do not currently use or do not intend to be fitted for a lower limb prosthesis; or (2) appear to have moderate to severe cognitive impairment, as evidenced by inconsistent responding to the study instruments.
