Recommendations on Standards for the Design of Medical Diagnostic Equipment for Adults with Disabilities, Advisory Committee Final Report

5.6 Stirrups.

5.6.1 Stirrups for Equipment Used by Patient in Supine, Prone, or Side-Lying Position. Where the equipment provides stirrups, it must also provide an alternate method to support, position, and secure the patient’s legs (specifically including sufficient support of the patient’s thigh, knee, and calf to stabilize the leg). This method will either supplement or serve as a substitute for the stirrups.
