Clinical Trial Summary

The goal of this clinical investigation is to evaluate the clinical benefits of a ventilating suspension interface for individuals with transfemoral amputation. The main aim of the investigation will be to evaluate the clinical user-reported benefits to skin health from using a ventilating lower limb prosthetic suspension system and compare it to a non-ventilating suspension system.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Subject perceived skin health (PEQ-RLH)	PEQ-RLH (Prosthesis Evaluation Questionnaire - Residual Limb Health) Questionnaire Mean of six 1-10 point scale items, higher score indicates better RLH	4 weeks
Secondary	Subject perceived activity restriction and prosthesis use, TAPES-R	Self-report: TAPES-R (Trinity Amputation and Prosthesis Experiences Scales) - Activity Restriction scale Mean of ten 3-point scale items, higher score indicates less restriction	4 weeks
Secondary	Subject perceived quality of life EQ-5D-5L	Self-report: EQ-5D-5L 5-level EQ-5D version (EQ-5D-5L) Use of AeroFit system provides non-inferior quality of life* 0-1.00 index value, higher value indicates higher QALY	4 weeks
Secondary	Incidents of prosthesis slippage, the need to remove liner to dry limb or liner and incidents of complete loss of suspension.	Self-report: In-house generated questionnaire on prosthesis slippage and the need to remove prosthesis due to moisture .; Higher score means worse slippage experience.	4 weeks
