• Aim– Examine utility of Amputee Mobility Predictor (AMP)-

Bilateral (AMP-B) to measure performance of functional tasks related to advanced skill activities in people with bilateral lower-limb amputation (BLLA).

– Determine correlation between AMP-B scores and 6-Minute Walk Test (6MWT) performance.

• Relevance– Original AMP is designed to assess mobility and functional

capabilities for people with unilateral lower-limb amputation. – No comparable measure exists for those with BLLA.

Method

• 26 male servicemembers participated: – 12 with bilateral transtibial amputation (BTTA).– 7 with bilateral transfemoral amputation (BTFA).– 7 with combination transtibial and transfemoral

amputation (TTA/TFA).

Results• AMP-B scores, AMP scores, and 6MWT distance:– Significantly differed between:

• Servicemembers with BTTA and TTA/TFA. • Servicemembers with BTTA and BTFA.

– Did not significantly differ between:• Servicemembers with BTFA and TTA/TFA.

• Scoring of 5 AMP items was modified because they necessitated intact knee joint to generate necessary torque requirements to perform activity without upper-limb assistance.

Conclusion

• Minor modifications in AMP scoring:– Do not alter total score.– Allow clinicians to determine mobility and

functional capabilities of servicemembers with BTFA and TFA/TTA.
