J Rehabil Res Dev. 2013;50(10):1241–52. http://dx.doi.org/10.1682/JRRD.2013.01.0003 Slideshow Project DOI:10.1682/JRRD.2013.01.0003JSP Aim – Investigate effect of brimless vs ischial ramus containment (IRC) prosthetic sockets when using vacuum-assisted suspension (VAS) on persons with unilateral transfemoral amputation (TFA). Relevance – Prosthetic socket is most important aspect of prosthesis. Connects person with amputation’s residual limb to components and ground during stance.

Participants: – 9 people with unilateral TFA. Interventions: – IRC VAS and brimless VAS sockets. Main outcome measures: – Coronal hip angle and vertical and lateral socket movement as measured by X-ray. – Skin pressure measured by Tekscan. – Preference measured subjectively.

Peak/stance mean pressure in medial proximal aspect of socket: – 322 mmHG in IRC. – 190 mmHg in brimless condition. Except for medial proximal pressure, no other measures reached statistical significance. All subjects found brimless design more comfortable than IRC short-term.
