Pre-Prosthetic Mobility as a Predictor of Functional Mobility after Lower Limb Amputation

There is a critical need for research evaluating the predictive validity of
pre-prosthetic functional assessments in individuals with recent lower extremity amputation.
Establishing reliable early-stage outcome measures could enhance the objectivity of K-level
assignments, inform prosthetic component selection, and ultimately improve rehabilitation
outcomes. The present study addresses this gap by investigating whether mobility assessments
conducted in the pre-prosthetic phase—specifically the AMPnoPRO—can predict post-prosthetic
functional mobility, as measured by validated tools such as the AMPPRO and a novel Functional Level Checklist. By analyzing the relationship between early functional
scores and subsequent mobility outcomes, this research aims to provide evidence for more
standardized and objective K-level classification practices in early prosthetic care.

This study was designed as a prospective, observational cohort study to examine the predictive
relationship between pre-prosthetic functional mobility and post-prosthetic mobility outcomes in
individuals with recent unilateral lower limb amputation. The primary aim was to determine
whether performance on the Amputee Mobility Predictor without Prosthesis (AMPnoPRO) in the
pre-prosthetic phase could accurately predict functional outcomes following initial prosthetic
fitting.
