The system includes an instrument for determining the anatomical, biomechanical, and physiological properties of a body segment that includes one or more force sensitive probes is provided. A human operator actuates one or more force sensitive probes, wherein the force sensitive probes are positioned at the surface of the body segment. The operator pushes on the force sensitive probes with varying force applied on the body segment to measure tissue deflection forces. The instrument may include one or more of gyroscopes, accelerometers, and magnetometers capable of measuring changes in tissue deflection caused by the force sensitive probes relative to a grounded reference frame in 3-D space, wherein the tissue deflection force data and the change in tissue deflection data are used to compute segment tissue viscoelastic properties. The instrument may also be untethered or wireless.

Measurement and ordering system for orthotic devices

A system for electronically capturing a subject's anatomy. Software programming directs the user to position the camera to recognize the anatomy. It uses anatomical features of the recognized subject's anatomy, patient data entered by the user and anthropometric data to estimate the optimal position of virtual markers. Furthermore, it places the virtual markers on an image presented to the user on the display screen at the estimated optimal position, while utilizing an auto-zoom and the virtual markers to zoom in to provide proper framing. The auto-zoom is utilized while maintaining a substantially fixed camera distance from the subject. The programming provides feedback based on the anatomical features for directing the user to move the camera appropriately relative to the virtual markers, thereby resulting in an optimized view of the anatomical information. The end-user software program captures the optimized view of the anatomical information via the camera to provide output data.
