The Amputee Mobility Predictor: an instrument to assess determinants of the lower-limb
amputee ability to ambulate. Arch Phys Med Rehabil 2002;83:613-27. Objectives: To describe the development of the Amputee Mobility Predictor© (AMP) instrument designed
to measure ambulatory potential of lower-limb amputees with (AMPPRO) and without (AMPnoPRO)
the use of a prosthesis, and to test its reliability and validity. Design: Measurement study using known groups method and concurrence with existing measures.
Setting: Academic medical center. Participants: A convenience sample of 191 lower-limb amputee subjects who had completed prosthetic
training, 24 in the reliability study (mean age ± standard deviation, 68.3±17.9y,
range, 28-99y) and 167 in the validity study (mean age, 54.8±18.6y; range, 18-100y).
Interventions: Not applicable. Main Outcome Measures: Intra- and interrater reliability; construct validy by known groups method; concurrent
validity by comparisons with 6-minute walk test, Comorbidity Index, age, and time
since amputation; predictive validity by comparison with 6-minute walk test after
controlling for other factors. Results: Interrater reliability was.99 for subjects tested with and without their prosthesis;
intrarater reliability was.96 and.97. Both the AMPnoPRO (P<.0001) and the AMPPRO scores (P<.0001) distinguished among the 4 Medicare functional classification levels. The AMP
correlated strongly with 6-minute walk scores (AMPnoPRO r=.69, P<.0001; AMPPRO r=.82, P<.0001) and the amputee activity survey (AMPnoPRO r=.67, P<.0001; AMPPRO r=.77, P<.0001), and negatively correlated with age (AMPnoPRO r=−.69, P<.0001; AMPPRO r=.56, P<.0001) and comorbidity (AMPnoPRO r=−.43, P<.0001; AMPPRO r=.38, P<.0001). Conclusion: The AMP with and without a prosthesis are reliable and valid measures for the assessment
of functional ambulation in lower-limb amputee subjects. © 2002 by the American Congress of Rehabilitation Medicine and the American Academy
