The devices may include patient-specific mating surfaces configured to engage the non-resected bone surface in a single relative position relative to the non-resected bone surface. The patient specific nature of the mating surface portion may be generated in the devices prior to the devices being brought into contact with the bone. The devices may include various cutting guides and holes for receiving fasteners to fasten the devices to the bone. The devices may include various features to enhance the stability and/or surface area contact between the devices and the bones.

The resilient assembly includes a first arm connected to the frame member, a second arm pivotally connected to the first arm, a spacing defined between the first and second arms, and a resilient member disposed in the spacing and connected to the first and second arms. The resilient member is resiliently deformable to permit movement of the second arm relative to the first arm, and to resiliently bias the second arm towards a rest position with respect to the first arm. The suspended undercarriage assembly provides suspension to a support wheel assembly relative to the frame member when connected to the second arm.

Abstract: Provided are methods and system for assessing a human subject's neurological and/or psychological status. The methods entail displaying visual tests to a human subject, wherein each of the visual tests includes a visual target signal, optionally with visual cue signals, for eliciting visual and, optionally, body part, movements by the subject. Following the display, the movements are then detected. The latency and/or correctness of such movements can then be used to assess the subject's neurological and/or psychological status. Also provided are methods and systems for assessing performance validity.
