Differences in function and safety between Medicare Functional Classification Level-2 and -3 transfemoral amputees and influence of prosthetic knee joint control

摘要: The functional differences between persons with amputation who are classified as Medicare Functional Classification Level (MFCL)-2 and -3 include the abilities to walk at various cadences negotiate environmental barriers outside home. This study compared effect of active microprocessor control passive mechanical prosthetic knee on function safety in 17 subjects transfemoral (8 MFCL-2 9 MFCL-3). Assessed tasks included hill stair descent, an attentional demand task, obstacle course. Self-reported measures concentration, multitasking ability, numbers stumbles falls. Active was associated significant improvements (p < 0.05) gait, speed (hills, course, task), ability multitask while walking for both cohorts. also reported a reduction 0.01) uncontrolled Over study, 50% 33% MFCL-3 transitioned higher MFCL. Results suggest that improves reduces frequency adverse events population is risk Use may allow expand their domain, transition MFCL, access additional options.
