Amputee Mobility Predictor-Bilateral: A performance-based measure of mobility for people with bilateral lower-limb loss

Abstract

Abstract-The Amputee Mobility Predictor (AMP) is an outcome measure designed to assess mobility and functional capabilities for people with unilateral lower-limb amputation. No comparable measure exists for those with bilateral lower-limb amputation (BLLA). The purpose of this study was to examine the utility of the AMP-Bilateral (AMP-B) to measure the ability to perform functional tasks related to participation in advanced skill activities in those with BLLA and to determine whether AMP-B scores correlated with 6-minute walk test (6MWT) performance. Twenty-six male servicemembers (SMs) completed the study: 12 with bilateral transtibial amputation (BTTA), 7 with bilateral transfemoral amputation (BTFA), and 7 with combination transtibial and transfemoral amputation (TTA/TFA). Significant differences existed between the AMP-B scores (p < 0.001), AMP scores (p < 0.001), and 6MWT distance (p < 0.05) for SMs with BTTA and TTA/TFA and SMs with BTTA and BTFA but not between those with BTFA and TTA/TFA. Scoring of five AMP items was modified because they necessitate at least one intact knee joint to generate the necessary torque requirements to perform the activity without upper-limb assistance. Minor modifications in scoring of the AMP do not alter total score and allow clinicians to determine the mobility and functional capabilities of SMs with BTFA and TFA/TTA.

Functional and Mental Health Status of United Kingdom Military Amputees Postrehabilitation

“…The cohort of amputees reported in this study had a mean NISS of 40AE15, which we believe constitutes the highest severity of traumatic amputee injury in the available literature. 11,12 Despite this, upon completion of a comprehensive and intensive rehabilitation pathway, these patients had functional and mental health status comparable with that of the general population. Patient mobility is a critical component of successful rehabilitation and vital in aiding ADL.…”

Predicting Walking Ability Following Lower Limb Amputation: An Updated Systematic Literature Review

“…The 6MWT can identify impairments of the musculoskeletal system that can affect ambulation ability such as weakness in the muscles that support ambulation (32). Chin et al reported that when older HDA patients are in good physical condition, they are successfully able to walk with a prosthesis in a community setting (10).…”

Powered knee and ankle prostheses enable natural ambulation on level ground and stairs for individuals with bilateral above-knee amputation: a case study

“…As a result, individuals with bilateral above-knee amputations can only walk for short distances and have a high risk of falling 4 , 5 . Most importantly, climbing stairs requires individuals to use their upper body strength, basically pulling themselves up the stairs because the knee prostheses cannot generate extension torque as necessary to lift the body up the step 6 , 7 . Most individuals do not have the strength to perform this movement, as a result, they are unable to ascend stairs 7 .…”
