There is disclosed a mobility aid for use by a user having a lower body amputation site. The mobility aid includes a lower body exoskeleton (LBE). The LBE has a pelvic support structure and a first leg and a second leg. Each of the first and second legs are movably coupled to the pelvic support structure, wherein at least the first and second legs are selectively actuable to move the lower body exoskeleton relative to a surface on which the mobility aid is positioned. The LBE also includes a carrier selectively positionable with respect to the lower body exoskeleton and, which in use, supports the user at or about an amputation site; and a harness system configured to, when in use, secure the user to the lower body exoskeleton.

A motion assistance apparatus includes a shank frame configured to support a shank of a user, a thigh frame configured to rotate relative to the shank frame and support a thigh of the user, and a driving frame configured to assist a motion of a hip joint of the user by transmitting power directly or indirectly to the shank frame.

An interface system includes a support belt, a strap assembly, and a frame system. The frame system includes a first frame member and a second frame member. The first frame member and the second frame member each respectively have an upper attachment portion configured to have an assistive device attached thereto at a first shoulder mount assembly and a second shoulder mount assembly, respectively. The first frame member and the second frame member are each respectively connected to the strap assembly and extend downward contouring laterally and connecting to the support belt. The first frame member and the second frame member contour laterally in opposed directions. The first frame member is connected posteriorly to the second frame member through a pair of hinge arms joined at a pivot connection.

An electromechanical transducer for a stimulation system includes: a housing; a movable element mounted inside the housing and capable of being moved in translation by means of at least a first elastic return element; an electromagnetic actuation system, including an electromagnet and a first magnet. The electromagnet is integral with the movable element. The first elastic return element includes a thermally insulating material. The electromechanical transducer further includes a heat-sensitive element associated with the electromagnet. Further, a stimulation system comprises the electromagnetic transducer and a vehicle including such a stimulation system.

A method and device for controlling a walking assist device is disclosed. The method includes determining a first state variable for a gait state of a user wearing the walking assist device based on a gait of the user, obtaining a second state variable which is smoothed and time-delayed from the first state variable, obtaining a third state variable by applying a torque control variable to the second state variable, and determining an assist torque to be provided by the walking assist device based on the obtained third state variable.

A wearable device and an exercise support method performed by the wearable device are disclosed. The exercise support method includes receiving exercise setting information associated with a lower body muscle that is selected by a user input, determining a torque profile to be applied to the wearable device based on the received exercise setting information, and operating an actuator of the wearable device based on the determined torque profile.

A pelvic floor pain relief device for use by humans. The device is spherical, and comprised of three layers. The core of the device is a compact compressible spherical core, having a compressibility rating sufficient to substantially support the weight of a human sitting thereon while allowing but minimizing the deformation of the sphere under the human load. A strengthening layer, consisting of randomly wound filament material, is wound around the exterior of the compressible spherical core to further minimize the deformation of the sphere in use. Finally, an exterior protective layer retains the filament of the strengthening layer in relation to the sphere and provides a cleanable surface. The method of use of the device is also disclosed.

A motion assisting device assists a movement of a wearer raising an upper body and includes a first assisting unit and a second assisting unit. The first assisting unit and the second assisting unit are attached to a left side surface and a right side surface of the wearer, respectively, and each include a power unit that swings a leg rod and applies, to the leg rod, a force in accordance with the swinging movement of the leg rod. The power unit is connected to a back surface frame that is a rigid body and connects the first assisting unit and the second assisting unit. A back plate of an upper body fixing member is connected to the back surface frame by a coupling member. The back plate is swingable at least in an up-down direction and a left-right direction with respect to the back surface frame.

A wearable lower extremity exoskeleton for regenerating a lower body motion functionality of paraplegic patients is provided. The wearable lower extremity exoskeleton has four active DOF and each DOF provided by an actuator disposed around a hip level and a back and/or a front of a user and provided by articulations.

An exoskeleton (1) having a plurality of autonomously operable modules (2.sub.RK, 2.sub.LK, 2.sub.RH, 2.sub.LH) each having a dedicated controller (23.sub.RK, 23.sub.LK, 23.sub.RH, 23.sub.LH) connected to an actuated joint. The exoskeleton (1) further having a multimaster electrical communicator (3) between the controllers (23.sub.RK, 23.sub.LK, 23.sub.RH, 23.sub.LH) of the modules (2.sub.RK, 2.sub.LK, 2.sub.RH, 2.sub.LH). The controller (23.sub.RK, 23.sub.LK, 23.sub.RH, 23.sub.LH) of each module (2.sub.RK, 2.sub.LK, 2.sub.RH, 2.sub.LH) is configured for: collecting information from sensors; sharing information with the remaining modules through the multimaster electrical communicator (3); determining which other modules (2.sub.RK, 2.sub.LK, 2.sub.RH, 2.sub.LH) are present; and autonomously calculating and commanding a desired trajectory of the actuated joint of the module (2.sub.RK, 2.sub.LK, 2.sub.RH, 2.sub.LH) for assisting the movement of the corresponding biological joint in coordination with the kinematic condition of other biological joints.
