Abstract:
A system and method by which movements desired by a user of a lower extremity orthotic is determined and a control system automatically regulates the sequential operation of powered lower extremity orthotic components to enable the user, having mobility disorders, to walk, as well as perform other common mobility tasks which involve leg movements, perhaps with the use of a gait aid.
Abstract:
An operator supervising a wearer of an exoskeleton is verified by performing a verification routine on the operator using the exoskeleton. If the verification routine is unsuccessful, the exoskeleton is caused to follow a pre-established response routine. If the verification routine is successful, movement of the exoskeleton is allowed.
Abstract:
A gait orthotic system includes a balance aid and a gait orthotic device. The gait orthotic device has a rigid attachment mechanism configured to securely and releasably couple the balance aid to the gait orthotic device. When the balance aid is coupled to the gait orthotic device, the gait orthotic device is supported in a standing position so that a user of the gait orthotic device is able to use his/her hands freely. When the balance aid is not coupled to the gait orthotic device, the user is able to use the balance aid for locomotion. In certain embodiments, the balance aid is a forearm crutch, a walker or a cane, while the rigid attachment mechanism is a clamp with an over-center latch.
Abstract:
Use of an exoskeleton by a wearer of the exoskeleton is improved through several features. In a first feature, the exoskeleton enters a gait therapy preparation mode to prepare the wearer for subsequent gait therapy. In a second feature, the exoskeleton enters a balance training mode to help the wearer learn to balance while wearing the exoskeleton. In a third feature, the exoskeleton prompts the wearer to shift weight and/or automatically shifts the wearer's weight in a center of pressure control mode. In a fourth feature, an element of variability is introduced into trajectory cycles performed by the exoskeleton in a trajectory cycle mode. Overall, the various disclosed operating modes can be used individually or in various combinations to enhance the rehabilitation or training of the wearer.

Abstract:
An exoskeleton includes a control system which incorporates a feedback system used to establish and communicate orthosis operational information to a physical therapist and/or to an exoskeleton user. The feedback system can take various forms, including employing sensors to establish a feedback ready value and communicating the value through one or more light sources which can be in close proximity to joints of the exoskeleton joints.
Abstract:
A powered orthotic system, such as an exoskeleton, is employed for rehabilitation purposes by adapting and adjusting to real-time needs in a rehabilitation situation whereby the system can be initially controlled to perform gait functions for a wearer based on a predetermined level of assistance but the predetermined level of assistance can be varied, based on one or more rehabilitation parameters or specific needs of the wearer undergoing therapy, through the application and adjustment of appropriate variables associated with operation of the system.
Abstract:
An exoskeleton can be reconfigured, adjusted and/or controlled on the fly utilizing devices which fall into three categories, particularly including a swappable unactuated leg, lockable transverse and coronal hip rotations, and software controlled free joints. More specifically, the first device allows for the creation of a modular joint system in which individual exoskeleton joints or limbs can be changed or swapped to optimize an exoskeleton for a particular user. The second device is concerned with mechanically controlling, such as locking and unlocking, joints thereby allowing, for example, an exoskeleton leg to pivot or not pivot in an axis that is not actuated. The third device allows an actuated exoskeleton joint to be adjusted on the fly using software to simulate a freely rotating joint. The various devices can be used either alone or in combination to enable any given exoskeleton to be appropriately reconfigured, such as when a patient advances during therapy.
Abstract:
A lower extremity orthosis is configured to be coupled to across at least one joint of a person for gait assistance and can incorporate knee, thigh, hip and ankle/foot assistive orthotic devices which can be used in various combinations to aid in the rehabilitation and restoration of muscular function in patients with impaired muscular function or control.
Abstract:
A powered orthotic system, such as an exoskeleton, is employed for overground rehabilitation purposes by adapting and adjusting to real-time needs in a rehabilitation situation whereby the system can be initially controlled to perform gait functions for a wearer based on a predetermined level of assistance but the predetermined level of assistance can be varied, based on one or more rehabilitation parameters or specific needs of the wearer undergoing therapy, through the application and adjustment of appropriate variables associated with operation of the system.
