J Rehabil Res Dev. 2013;50(8):1069–78. http://dx.doi.org/10.1682/JRRD.2012.11.0204 Slideshow Project DOI:10.1682/JRRD.2012.11.0204JSP Aim – Identify important pump-performance metrics and develop techniques to characterize evacuation performance of prosthetic vacuum pumps. Relevance – Despite increasingly widespread adoption of vacuum- assisted suspension systems in prosthetic clinical practices, gaps exist in the scientific knowledge guiding clinicians’ choices of existing products.

All measurements were obtained at 57.6 kPa vacuum gauge pressure.

Sensitivity was less pronounced for mechanical pumps. – Future improvements for testing of mechanical vacuum pumps were proposed.
