The invention relates to a system for adjusting pressure locally acting on the skin. Said system includes a set of adjacent modules distributed so as to form a layer. Each module includes a cushion capable of changing shape and comprising a cavity, a valve, a tank, and a pressure sensor, wherein the cavity and the tank are in communication with each other by means of the valve, and the sensor is placed so as to sense pressure directly or indirectly acting on the cushion. The system also includes a feedback loop arranged such as to increase or decrease the change in the shape of the cushion on the basis of the pressure detected by the sensor. The system according to the invention can be built into a shoe so as to re-establish normal plantar pressure under the entire sole of the foot, which is particularly desirable for athletes or for patients suffering from diabetes mellitus or leprosy. It is also possible to incorporate the system according to the invention into a (bed or wheelchair) mattress so as to prevent decubitus ulcers in patients with neurological diseases (hemiplegia, paraplegia, tetraplegia, multiple sclerosis, amyotrophic lateral sclerosis) and any other sensory and/or motor deficit diseases.

A knee examination method includes the steps of situating a patient on a patient support adjacent a robotic knee testing apparatus, setting up the robotic knee testing apparatus, further setting up the leg of the patient relative to the robotic knee testing apparatus, and, after the steps of setting up and further setting up, examining knee laxity of a knee of the patient. The step of examining includes operating the robotic knee testing apparatus to manipulate the tibia positioning assembly.

A method includes obtaining rotational data and translational data for a joint, the rotational and translational data being indicative of rotational and translational movement of the joint during rotational and translational joint testing, respectively, the rotational and translational joint testing being implemented by a robotic testing apparatus applied to the joint. A quantity indicative of joint play of the joint is computed. The quantity is computed via a function of the rotational data and the translational data. The method includes determining whether the computed quantity exceeds a joint play threshold and, if the computed quantity exceeds the joint play threshold, comparing the rotational data and the translational data with preset rotational data and preset translational data for the rotational and translation joint testing, respectively.

The invention relates to a system to detect a first gas, the system comprising: a mattress assembly defining a support surface including: o a first array of gas sensors, each gas sensor of the first array being adapted to measure an amount of a first gas in the surrounding of a portion of the support surface and adapted to output data indicative of the measured amount of the first gas, so that the amount of the first gas in a first array of surface portions of the support surface is sensed over time; and o a transmitter adapted to send a signal to an external device containing data indicative of the measured amount of the first gas. The invention relates also to a method to detect the first gas.

A diabetic complications monitoring apparatus and a diabetic complications monitoring system using the same, includes a support fixture having a liquid crystal color changing sheet that is located on an upper surface of the support fixture and displays a foot heat distribution based on a color, a transparent glass that is located on an upper surface of the liquid crystal color changing sheet and comes into contact with user's feet to support the user's feet, a foot heat distribution measurement unit that includes a camera for imaging the liquid crystal color changing sheet and extracts and outputs a foot heat distribution from an image of the camera, a processor that acquires and outputs whether a disease occurs, or a position and size of occurrence of a disease, based on the foot heat distribution, and a data input/output device that audioizes and visualizes an output result of the processor.

An article of footwear includes an upper and a sole structure with a sole member. The sole member can be manufactured using a customized cushioning sole system. A user's foot morphology and/or preferences may be used to design the sole member. The sole member can include a set of pinpoint apertures that are formed along the outer surface of the sole member to form at least a first distribution of apertures associated with a first density and a second distribution of apertures associated with a second density, wherein the first density is greater than the second density.

A control system for a movement reconstruction and/or restoration system for a patient, comprising at least one sensor, at least one controller, at least one programmer, at least one stimulation system,
wherein the controller is connected with the sensor, the programmer and the stimulation system,
wherein the sensor is part of or attached to a training entity in order to create and/or guide a movement model for a patient and/or adjust stimulation settings based on sensor input.

A method for making an article for application to the human body. Data from measurement of pressures across an area of a person's body is obtained, which is then corresponded to a two-dimensional pressure map of a model of an article for application to that body area and identifying pressure-point locations and a pressure value for identified pressure-point location within the pressure map. Each different pressure value has a compression unit structure corresponding to that pressure value. The article is formed by generating the assigned respective structures in an integrated one-piece construct through layerwise build up in an additive manufacture system, where the build up includes a process that forms a joinder in an interface between adjacent contiguous structures which differ in geometry from one another so as to bond those contiguous structures together across the interface.
