Prosthetics and Orthotics Research

Prosthetics and orthotics research in the Mayo Clinic Motion Analysis Lab includes the following focus areas:

Comparative performance of dynamic elastic response prosthetic feet

The purpose of the lab's research on dynamic elastic response feet is to compare the functional performance of people with transtibial amputation using two types of prosthetic foot designs: carbon fiber versus fiberglass composite.

Comparison of postoperative care after transtibial amputation

The Motion Analysis Lab quantifies and compares the wound healing and physical behaviors of groups of patients who have received different rigid removable dressings as postoperative care after transtibial amputation.

Dr. Kaufman's research team uses triaxial accelerometers to measure positional changes and task frequency, allowing a comparison of patient activity levels. The team combines standardized digital photography and grading by a board-certified dermatologist to quantify incision site skin health and wound healing.

Improved training program for fall prevention of war fighters with lower extremity trauma

Dr. Kaufman's lab is working to accelerate the rehabilitation process, significantly reduce fall risk, and facilitate return of maximal functional capabilities for active duty or retired service members who have suffered lower limb trauma — specifically transfemoral amputation, bilateral lower extremity amputation and limb salvage procedures.

The lab is applying a perturbation-based technique to these patient groups' rehabilitation. The technique has previously been shown to successfully reduce falls in war fighters with unilateral transtibial amputations.

Risk factors and costs associated with accidental falls among adults with above-knee amputations (AKAs)

The lab is conducting a population-based study to determine the risk and predictors of falls among adults with AKAs compared with individuals without lower limb amputations, and to determine the annual direct medical cost of falls among adults with AKAs compared with adults without lower limb amputations.

Steerable powered ankle-foot prostheses for increased mobility in people who have had amputations

The long-term goal of this focus area is to explore maneuverability in design of assistive robot prostheses for enhancing the mobility and well-being of people with amputations as well as aging populations.

Development of a national orthotic and prosthetic registry

The purpose of this proposed work effort is to produce a preliminary list of data elements that can be used in a national orthotic and prosthetic registry, with a long-term goal of improving the delivery and quality of orthotic and prosthetic care to patients.

Prosthetic fit assessment in people with transtibial amputations secondary to trauma

The Motion Analysis Lab is conducting a prospective validation study to quantitatively evaluate a newly created assessment system (ProFit) in a group of 60 patients. This focus area aims to improve the quality of prosthetic fitting.
