SoundFit is a patented ultrasonic tool that monitors and records relative motion between a prosthesis socket and the bone within a remaining limb after amputation. Accurate and quantitative measurement of relative bone-to-prosthesis location during prescribed exercises such as walking for lower limb, or lateral arm raises for an upper limb, enables custom, comfortable fitment and high performance mechanical energy transfer, filling the knowledge gap that currently exists when trying to assess the performance of a socket interface.
There is a clear industry need for determining acceptable ranges for socket performance metrics values. These metrics may include sagittal/frontal range of motion and peak velocity during an activity, which correlate with interface stiffness and damping. These performance metrics, derived with FTL’s SoundFit, allow analysis of industry-wide statistical trends for direct application by prosthetics clinicians.
FTL’s SoundFit serves as a guide during the fitment process, allowing comparison of a socket’s performance to trends seen in the community of subjects having similar impairments, physiology and mobility. Driving the socket fitment with data rather than subjectivity will help to enhance a patient’s interaction with the world via a prosthesis, and ultimately will improve the patient’s quality of life.
