Consistency, precision, and accuracy of optical and electromagnetic shape-capturing systems for digital measurement of residual-limb anthropometrics of persons with transtibial amputation

In this study, prosthetists and prosthetics students used two different digital systems to capture the shape of three limb models. Both systems were accurate and consistent, and both participant groups produced similar results. The digital shape-capture results were also similar to the same measurements collected with traditional calipers and tape measures. Prosthetists may consider digital shape capture for all patients with limb loss, including veterans, even if they do not plan to use it to build the socket.
