A retrospective study from four US clinics examined AMP scores obtained during lower limb fittings. The results characterize AMP scores by amputation level and K-level, but also reveal differences between sites in how the AMP is used in the assignment of K-Level. 

Lifetime Mobility Values Following Lower Limb Loss 

Bretta L. Fylstra, PhD

Previous work has generated normative values of mobility across age and etiology for individuals with lower limb amputation; however, age groupings were reported in seven groups that spanned approximately 10 years each, due to sample size limitations. The purpose of this study was to further stratify mobility outcomes for individual years of patient age to enable clinicians more individualized mobility goal setting for their patients. Secondarily, an initial analysis to investigate how these mobility goals may change dependent on type of prosthesis was performed for patients with microprocessor knees integrated into their care. Results from this study generated a set of equations to predict mobility based on age, etiology, and amputation level to provide clinicians with additional information to set goals for their patients. 

Recent Amputee Functional Level Determination 

Cory Cacciola, MS, CPO

This study was a retrospective chart review that assessed the potential of using a standardized survey of self-reported prior mobility and comorbidity information to assign Medicare Functional Capacity Level (MFCL K-level) for a person with a new amputation. 

OASIS 2: Mobility Differences with Specific Prosthetic Feet Across Procedure Codes 

Shane Wurdeman, PhD, CP

The current study represents analysis of real-world evidence generated during routine clinical practice. The finding of similar function across feet that sustained their coding and those that were reclassified from L5987 to L5981 underscores the value of clinical outcomes to inform new processes by which coding decisions can be made based on the functional benefit for patients rather than mechanical features.
