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.

In at least some aspects, the present concepts include a method for configuring an assistive flexible suit including the acts of outfitting a person with an assistive flexible suit, monitoring an output of at least one sensor of the assistive flexible suit as the person moves in a first controlled movement environment, identifying at least one predefined gait event using the output of the at least one sensor, adjusting an actuation profile of the at least one actuator and continuing to perform the acts of monitoring, identifying and adjusting until an actuation profile of the at least one actuator generates a beneficial moment about the at least one joint to promote an improvement in gait. The at least one controller is then set to implement the actuation profile.

A medical monitoring and treatment device that includes a therapy delivery interface, a plurality of therapy electrodes coupled to the therapy delivery interface, a plurality of electrocardiogram sensing electrodes to sense electrocardiogram signals of a patient, a sensor interface to receive the electrocardiogram signals and digitize the electrocardiogram signals, and at least one processor coupled to the sensor interface and the therapy delivery interface to analyze the digitized electrocardiogram signals, to detect a cardiac arrhythmia based on the digitized electrocardiogram signals, and to control the therapy delivery interface to apply electrical therapy to the patient based upon the detected cardiac arrhythmia. The at least one processor is further configured to analyze a frequency domain transform of the digitized electrocardiogram signals, to determine a metric indicative of a metabolic state of a heart of the patient, and to accelerate or delay application of the electrical therapy based upon the metric.

A skin treatment device includes a roller disposed about a rotational axis, with a plurality of flexible, compressive skin contact elements distributed circumferentially about the roller. Compressive elements include a first longitudinal section coupled to the roller, a second longitudinal section with a radially outer skin contact surface extending opposite the first longitudinal section, and a transverse section with one or more web members connecting the first and second longitudinal sections at an angle. The angles of the web members are adapted to generate lateral displacement of the contact surfaces in response to a compressive load. The lateral displacements of adjacent pairs of contact surfaces are defined in opposite directions, parallel and antiparallel to the rotational axis, in order to provide an elastic stretching treatment to the skin. Electrodes can be disposed adjacent the roller, on the housing or between adjacent contact surfaces, in order to provide a current treatment.

A method is described for providing deficit-adjusted adaptive assistance during movement phases of an impaired ankle. The method includes determining, on the processor, a value for a deficit parameter for each movement phase of a compound ankle function based on a difference between a parameter trace for a normal subject and the parameter trace for an impaired subject. The method further includes determining, on the processor, an adaptive magnitude for the robot-applied torque based on the value for the deficit parameter. The method further includes applying, to the robot joint, the adaptive magnitude for the robot-applied torque in only a first plane for the current movement phase, based on an adaptive timing. An apparatus is also described for providing deficit-adjusted adaptive assistance during movement phases of the impaired ankle.

A movement assistance apparatus to be provided in a movement assistance device and configured to execute a movement assistance operation for assisting movement of a user includes a mode switching control unit configured to switch, based on a magnitude of a surrounding risk on the movement of the user, a power mode between a normal mode in which the movement assistance operation is executable and a power saving mode in which a power consumption is smaller than a power consumption in the normal mode. A condition for setting the power mode to the power saving mode includes a condition that the surrounding risk satisfies a predetermined low-risk condition.

The present disclosure relates to a rolling walking device for the therapy and diagnosis of a person with a motor restriction. The walking device comprises at least one axis and a plurality of wheels, a support device for the person, which is configured such that the person can sit on the support device while using the walking device and simultaneously rest with the front of their upper body, and, optionally, with the head, at least partially on the support device, and one or more sensors configured to generate sensor data associated with a therapeutic interaction of the person with the walking device.

A gait management apparatus applies stimulation to a user suffering from a neurological disease (such as Parkinson's Disease) gait dysfunction. Motion sensors are arranged to be worn by a patient, and electrical stimulation electrodes are on the legs for stimulation. A controller receives motion sensing signals, and processes these signals to generate stimulation signals for operation of the electrodes to stimulate limb movement upon detection of a gait abnormality. There may be a user actuator for user actuation of electrical stimulation, and the inputs may be a series of taps. The controller may provide signals to prevent occurrence of freezing of gait when it senses that a patient is walking or has an intention to walk. Also, it may apply stimulation at an intensity level which is insufficient for functional muscle stimulation but sufficiently high to trigger activation of efferent nerves.

An assistive device for stair-climbing assistance includes a powered rail-sliding platform that assists its user through a unique human interface. The device provides powered assistance (a gentle pulling force) and protection (through a safety belt) to help users climb or descend stairs.

A method and apparatus for controlling a walking assistance apparatus are provided. The apparatus may include a detector configured to detect a first step of a user, based on measured right and left hip joint angle information, a reconstructor unit configured to reconstruct knee joint information matched to the right and left hip joint angle information based on knee joint trajectory information in response to the user's steps, and a torque generator configured to generate a first torque applied to a first leg corresponding to the first step. The torque generator may generate the first torque, based on a second torque applied to a second leg that is opposite to the first leg and that corresponds to a second step preceding the first step.
