The microprocessor-controlled foot Meridium is a prosthetic component
with adjustable stance-phase characteristics.
OBJECTIVES: To investigate
subjects' and prosthetists' perception of safety, walking, and satisfaction
during first routine fittings. STUDY DESIGN: Multicenter, prospective,
observational cohort study. METHODS: Data regarding demographics, fitting
process, safety, daily life activities, and satisfaction were obtained through
questionnaires. The follow-up period was 7 months.
RESULTS: In all, 89% of 70
users were satisfactorily fitted within the first two visits. Compared to
previous feet, users reported improvements in walking on level ground (54% of
subjects), uneven ground (82%), ascending (97%), and descending ramps (91%). More
than 45% of the users perceived an improvement in safety and stability while
standing and walking. No difference was observed in concentration, exertion, and
pain. Overall user satisfaction with Meridium was 50% and the foot was preferred
by 40% of users. Amputation level, age and mobility grade did not influence
subjects' preference. Prosthetists recommended Meridium for 59% of subjects. A
correlation analysis revealed that transfemoral amputees fitted with Genium
and/or having a long residual limb strongly preferred Meridium ( p < 0.05).
CONCLUSION: Meridium was appreciated by amputees with a preference for natural
walking and requirement to safely and comfortably negotiate uneven terrain and
slopes. Clinical relevance Amputees preferring Meridium perceive benefits with
safe, comfortable, and natural walking.
While the perception of benefits
regarding the negotiation of uneven terrain and slopes is very high, the correlation to product preference is moderate. Individual assessment and trial
fitting might be essential to identify patients who benefit greatly.
