Össur Logic, is the smart app for Össur Bionic prosthesis, the hardware used in clinical care. For prosthetists, it can program the microprocessor limb components manufactured by Össur that VA OPPCS clinicians fit and deliver to Veterans every day. It is the clinician's only way to alter the settings of the knee to change how the knee responds when a Veteran walks faster, slower, or stands still and provides full access to setting up the prosthesis. For users, it offers insight into parameters like battery level and step count as well as access to configurations and the latest instructions for use.
