A frame assembly including a first longitudinal member, a second longitudinal member spaced apart from the first longitudinal member, a third longitudinal member configured to diagonally connect the first longitudinal member and the second longitudinal member, a plurality of first distance maintaining members configured to connect the first longitudinal member and the second longitudinal member, and a plurality of second distance maintaining members configured to connect the second longitudinal member and the third longitudinal member is disclosed.
Abstract:
An apparatus (100) for gait training has a movable base (200) comprising at least one drive unit (210) for moving the movable base, an arm arrangement (300) extending from the movable base, a weight support system (400) to enable a person to be at least partially suspended from above via said arm arrangement, a movement detector to detect a movement of the person and a control unit adapted to control said drive unit(s) in response to a movement of the person detected by the movement detector such that the movable base follows the person in a predetermined distance range and in a predetermined angular range with respect to a movement direction of the person.
Abstract:
An exoskeleton comprises a torso brace, configured to be coupled to a torso of a user, and a leg support, configured to be coupled to a leg of the user. A plurality of links couples the torso brace to the leg support. The plurality of links includes a first link, coupled to the torso brace at a first pivot point, and a second link, coupled to the leg support at a second pivot point. The first link is coupled to the second link through a third pivot point located between the first and second pivot points. The first pivot point enables adduction of the leg support, and the third pivot point enables abduction of the leg support.
Abstract:
A garment with prepositioned, definite sensory stimulating devices attached. These sensory stimulating devices include, but are not limited to, electrical stimulation, audio and physical stimulation such as localised force generation, compression, constriction, vibration, and surround sound. Predetermined and defined actuators allow the wearer to receive tissue, nerve and/or muscle stimulation and/or contraction so that the stimulation is precise as determined by its ability to conform to the scientific methodology of repeatability, reproducibility and reliability; this being due to consistency of actuator positioning in one or multiple locals on the human body. A personal surround sound can also be integrated to the garment to ensure the wearer is always in the optimal position relative the speakers. These actuators can be force generators within the garment for the wearer to feel impact or apparatus or electrodes included in the garment to locally constrict and increase pressure on the wearer.
Abstract:
A massage cushion assembly for providing a massage to a user resting on the massage cushion assembly is provided. The massage cushion assembly includes a body supporting portion having a first surface and a second surface opposite the first surface, a base portion defining one or more slots extending longitudinally through the base portion, and a massage unit including one or more massage members. Each of the massage members is movable along a length of a particular slot and between a raised position and a lowered position. Each massage member is further positioned in a particular slot such that a head portion of the massage member extends out of the slot and presses against the second surface of the body supporting portion when the massage member is in the raised position.
Abstract:
The proposed apparatus and method relate to restorative sports medicine and patient rehabilitation with neurological motoric disorders. A patient is positioned in equilibrium by suspension devices for patient's body parts. The suspension devices are moved by actuating mechanisms with an electro-pneumatic drive and actuating components, controlled by a programmed PC, motivating the patient by controlling an object in a virtual gaming environment, to restore movements when there is an initially minimal or a complete absence of physical activity. The effectiveness is judged according to the reduction of energy consumption of the drives. The apparatus includes a base composed of two parallel guides with movable crossbars on which the actuating mechanisms are pairwise movably arranged, monitoring and control units, the PC, sensors detecting the state of the actuating mechanisms, and power sources. There are units for analyzing the energy consumption of each drive and for assessing the treatment results.
Abstract:
A motorized exoskeleton system for facilitating locomotion for a user, the system including a motorized exoskeleton device, one or a plurality of sensors to sense one or a plurality of parameters indicative of a state in which a user of the motorized exoskeleton device is falling, and an airbag unit comprising one or a plurality of airbags configured to deploy in response to the sensed state.
