Methods and systems for bedsore prevention. In accordance with various embodiments, methods and systems use information available from ECG and/or EMG sensor devices to determine whether a patient has performed a qualified movement within a predetermined time period. Upon determining a patient has not performed a qualified movement within the predetermined time period, a notification to that effect may be communicated to a clinical team member.

The present invention provides systems, methods, and articles for temperature conditioning a surface. An article is formed from a first layer having a plurality of openings and a second layer having a corresponding plurality of openings. At least one interior chamber constructed and configured to retain a fluid without leaking is defined between an interior surface of the first layer and an interior surface of the second layer. At least one flexible fluid supply line delivers the fluid to the at least one interior chamber. At least one flexible fluid return line removes the fluid from the at least one interior chamber. At least one control unit that is operable to selectively cool or heat the fluid is attached to the at least one flexible fluid supply line and the at least one flexible fluid return line.

Multi-component systems and methods for determining the proximity of surgical tools to key anatomical features are provided. The inventive systems and methods can be applied in any surgical procedure requiring precision to avoid damage to key anatomical features such as nerves, with a particular example being the robotic cochlear implantation minimally invasive approach to cochlear implantation. Use of purpose built surgical robots, electromyography and tissue impedance, stereotactic tracking and drilling force/bone density measurements are all key components, with inputs from these various modalities being dynamically weighted. In the example of robotic cochlear implantation, the inventive concepts are used to provide key surgical guidance so as to avoid damage to the facial nerve and the chorda tympani, among other anatomical features.

The present application relates to devices and systems for rehabilitation of the locomotor system, for example limbs. In particular, the present application discloses an apparatus, more in particular a robotic platform capable of optimizing gravity-dependent trunk movements, enabling overground locomotion in non-ambulatory individuals with spinal cord injury and stroke, while promoting durable motor improvement when delivered during gait rehabilitation facilitated by electrical spinal cord stimulation.
