Abstract:
A body weight support system includes a tether configured to be coupled to an attachment device worn by a user to couple the user to the body weight support system. A method of providing gait training includes defining a reference length of the tether when the attachment device is in an initial position and defining a threshold length of the tether. A first amount of body weight support is provided during the gait training as the user moves relative to a surface and the length of the tether is less than the threshold length. A second amount of body weight support is provided during the gait training as the user moves relative to the surface and the length of the tether is greater than the threshold length. The method further includes displaying data associated with the gait training on a display of an electronic device.
Abstract:
The embodiments and methods described herein relate to an improved functional electrical stimulation (FES) orthosis. An apparatus can include a frame assembly, an electrode assembly, and an electric stimulator. The frame assembly is removably coupleable to a portion of a limb. The electrode assembly is configured to be in electrical communication with a portion of a neuromuscular system of the limb, and includes first and second sets of electrodes. The electric stimulator is in electrical communication with the electrode assembly. The electric stimulator is configured to send a first signal substantially during a first time period and via a first channel to the first set of electrodes for stimulation of a neuromuscular system of the limb, and is configured to send a second signal, during at least one of the first time period or a subsequent second time period, via a second channel to the second set of electrodes for stimulation of the neuromuscular system of the limb.
Abstract:
A system includes at least three sensors, an electrode array, a muscle stimulator, and a microprocessor. The sensors are configured to be arranged substantially in a common plane and associated with a foot of a body. Additionally, each of the sensors are configured to produce a signal associated with an orientation of the foot. The electrode array is coupled to a lower limb of the body and configured to stimulate at least one muscle of the lower limb. The muscle stimulator is coupled to the electrode array and configured to output a muscle stimulation signal to the electrode array. The microprocessor is coupled to the sensors and configured to calculate an orientation of the foot based on the signals produced by the sensors. Additionally, the microprocessor is configured to control the muscle stimulation output via the muscle stimulator based on the calculated orientation of the foot.
Abstract:
In one embodiment, a method includes implanting an implant entirely under the subject's skin. The implant includes a passive electrical conductor of sufficient length to extend from subcutaneous tissue located below one of a surface cathodic electrode and a surface anodic electrode to the tibial nerve. The surface electrodes are positioned in spaced relationship on the subject's skin, with one of the electrodes positioned over the pick-up end of the electrical conductor such that the portion of the current is transmitted through the conductor to the tibial nerve, and such that the current flows through the tibial nerve and returns to the other of the surface cathodic electrode and the surface anodic electrode. An electrical current is applied between the surface cathodic electrode and the surface anodic electrode to cause the portion of the electrical current to flow through the implant to stimulate the tibial nerve.
Abstract:
An apparatus includes a first tubular member and a second tubular member coupled to the first tubular member. The first tubular member defines a longitudinal axis and a lumen substantially coaxial with the longitudinal axis. The lumen of the first tubular member is configured to receive at least a portion of an elongate implant. A distal end portion of the first tubular member is tapered along the longitudinal axis. The second tubular member defines a longitudinal axis and a lumen substantially coaxial with the longitudinal axis of the second tubular member. The second tubular member is coupled to the first tubular member such that the longitudinal axis of the first tubular member is substantially parallel to the longitudinal axis of the second tubular member. A distal end portion of the second tubular member is tapered along the longitudinal axis of the second tubular member.
Abstract:
An apparatus includes a percutaneous connection port configured to convey an electrical signal between an electrical device disposed outside of a body and an electrical member disposed within the body. The percutaneous connection port has a distal portion and a proximal portion. The proximal portion includes a surface configured to be accessible from a region of the body. The distal portion includes an anchor configured to be disposed within the body. The anchor has a curved shape about an axis substantially parallel to a skin of the body.
Abstract:
A body weight support system includes a trolley, a powered conductor operative coupled to a power supply, and a patient attachment mechanism. The trolley can include a drive system, a control system, and a patient support system. The drive system is movably coupled to a support rail. At least a portion of the control system is physically and electrically coupled to the powered conductor. The patient support mechanism is at least temporarily coupled to the patient attachment mechanism. The control system can control at least a portion of the patient support mechanism based at least in part on a force applied to the patient attachment mechanism.
