A soft-inflatable exosuit for knee rehabilitation is fabricated in two different beam-like structures (I and O cross-section actuators) and mechanically characterized for their torque performance in knee-extension assistance. The fabrication procedure of both types of actuators is presented as well as their integration into a light-weight, low-cost and body-conforming interface. To detect the activation duration of the device during the gait cycle, a soft-silicone insole with embedded force-sensitive resistors (FSRs) is used. In evaluation studies, the soft inflatable exosuit device is tested for its ability to reduce muscle activity during the swing phase of the knee. Using sEMG (surface electromyography) sensors, the rectus femoris muscle group of a healthy individual is recorded while walking on a treadmill at a constant speed, with and without the soft device.

A method and an apparatus for capturing a visual field of a person having a scotoma, in particular a central scotoma, are disclosed. The method includes continuously capturing the eye alignment of the person with a capturing unit, sampling the visual field of the person point-by-point to determine points suitable and not suitable for sight in the visual field of the person, finding the scotoma as a region with a multiplicity of points not suitable for sight, calculating an outer boundary line of the scotoma, calculating an outer enveloping curve, which surrounds the outer boundary line of the scotoma at a predetermined distance, and displaying the outer enveloping curve on a display unit. The enveloping curve is perceivable by the person on the display unit as a frame of the scotoma.

A machine that combines three sections bound to each other by the corresponding dynamic swivels that are driven from a remote control of adjustment and command (R). The first section constitutes the main body (A) wherein a fixed frame whereby a sliding carriage (D) is defined, which is arranged associated with a first motor reducer (M1) which drives its rectilinear movement, in the horizontal plane and in both senses; said sliding carriage (D), by one end, is bound to an intermediate arm (B), which makes up the second section of the machine, being arranged over a pivoting transverse axis that is into a first dynamic swivel, which is arranged associated to a second driving motor reducer (M2) so that said intermediate arm (B) may make a pivoting movement in the vertical plane, with circular direction in both senses; said intermediate arm (B), by its other end, is bound to a head of the massage actuator (C), that makes up the third section of the machine, being arranged over a transverse axis that forms a second dynamic swivel, which is arranged associated to a third driving motor reducer (M3) so that said head of massage actuator may make a pivoting movement in the vertical plane, with circular direction in both senses; an actuator piston (P) is arranged into the head of the massage actuator (C) which transforms the rotating movement that transmits the output axis of a fourth motor reducer into an alternative linear movement that is transmitted to the piston for massage (23); constituting the four motor reducers an electronic driving installation by remote control, through which the positioning of each of the mobile parts duly bound to the rotating coders and end-of-travel positions is commanded. The electronic driving installation is comprised of the electronic controlling plate (E) installed in the main body (A) and includes a remote control processor (MP2) that receives the order, processes the information and sends it through the FR antenna (a4) of the remote control (R), to the FR antenna (a1) of the electronic system (E) installed into the machine, that communicates the information to its processor (MP1). The electronic installation of remote control includes the option of saving, through memories, the previous adjustment that the user establishes in each case.

Systems, devices and methods for providing active and/or passive compression therapy to a body part can include a compression device worn over a compression stocking. The compression device can have a pulley based drive train that is driven by a motor to tighten and loosen compression elements, such as compression straps, in a precise, rapid, and balanced manner. Sensors can be used in the compression device and/or compression stockings to provide feedback to modulate the compression treatment parameters.

The invention relates to an apparatus (1) for unloading a user's body weight during a physical activity of said user (4), particularly for gait training of said user (4), comprising: a plurality of ropes (41, 42, 43, 44), wherein each rope (41, 42, 43, 44) extends from an associated drive unit (510, 520, 530, 540), is deflected by a passively displaceable deflection device, e.g. a device that is displaceable by means of the forces in the deflected ropes, and then runs to a first free end (41 a, 42a, 43a, 44a) of the respective rope (41, 42, 43, 44), and a node (60) being coupled to said first free ends (41 a, 42a, 43a, 44a) and being designed to be coupled to said user (4), wherein the drive units (510, 520, 530, 540) are designed to retract and release the respective rope (41, 42, 43, 44) so as to adjust a current rope force (FR) along the respective rope (41, 42, 43, 44), which current rope forces add up to a current resulting force (F) exerted on said user (4) via said node (60) in order to unload the user (4) upon said physical activity. Further, the invention relates to a method for controlling such a system.

The present invention discloses ventilation apparatus, comprising a casing with a first vent and a second vent, a fixed spacer disposed within the casing, and a movable spacer in operative connection with a power mechanism. Also discloses herein are methods for ventilating a subject, by synchronously providing a positive pressure ventilation and a negative pressure ventilation using the ventilation apparatus described herein.

The invention relates to a pain management device with a body portion having an hourglass shaped, elongated handle with an arm at one end for releasably attaching one or more treatment attachments, one or more generally planar scraping wings for Gua Sha treatment, and a motor inside configured to impart vibration in each of several modes optimized for vibration therapy. The invention may also include a kit with the pain management device, and one or more treatment attachments designed for unilateral or bilateral vibration application adjacent to trigeminal and/or vagus nerves. The treatment attachment may have two or more pivotable arms that extend along an axis generally perpendicular to the elongated handle when attached to the pain management device.

Method for assessing and preferably ameliorating the symptoms of a medical condition, optionally lymphedema, comprising obtaining a preferably both electrically powered and portable treatment apparatus capable of contacting, via a treatment head, a target area on the skin of a patient and introducing low-pressure suction thereto, wherein the apparatus, preferably the treatment head thereof, contains at least one sensor element to measure at least one physiological characteristic regarding the tissue underlying the target area of the patient, preferably indicative of fluid content thereof, and applying the treatment apparatus to the patient to measure said at least one physiological characteristic. A treatment apparatus for executing the method is presented.

A lower body electrical muscle stimulation exercise system for exercising the legs of a paralyzed user which incorporates electrical stimulation of leg muscles. The device is portable, light-weight and functional. The device is placed in front of a user who is sitting in a chair. The user's legs may be placed on moveable leg supports. An electric motor rotates a bicycle crank assembly which moves the legs of a user in a back and forth bending motion. Electrical stimulation is then activated which contracts or relaxes the leg muscles. The stimulation is sequentially activated by a Master Processor and a Transcutaneous Electrical Nerve Stimulator (TENS) unit. The present invention is designed to stop the deterioration of the leg muscles and restore the functionality of the legs.
