Review of Lower Limb Prosthesis Patient Activity Level Assessments Through Interviews

Document Type


The prosthesis components a lower limb amputee receives are determined by their assigned K level.
K levels are designated based on an activity level assessment of the patient. There are known issues
with the reliability of the assessments and the consistency of K level allocations between clinics,
especially when deciding between a K2 and K3 patient. It has been proposed that an objective system
that can assess a patient’s activity level outside of a clinic could improve the reliability and consistency
of these assessments. To fully understand the sources of the issues, and therefore the requirements
of the objective system, interviews were conducted with 6 clinical experts in activity level
