Abstract: The present invention relates methods for assisting a user having paralyzed muscles in walking. The methods focus on addressing foot drop and stimulating arm swing to aid in balance and mimic a “normal” person walk. The methods utilize a system capable of monitoring the gait cycle of the user and wireless transmitting signals to stimulation devices attached to the user's body.

Abstract: The present invention relates to devices and methods for a joint linkage device suitable for training multi-joints in a single limb. The joint linkage device is capable of rotation at a proximal end and a distal end. The device includes a proximal end having an upper plate, a middle plate, and a lower plate, a distal plate, a side bar, a main bar, a switch mechanism, and an extended bar. In use, a torque from a motor is applied to the upper plate to provide a user with an assistance torque, a resistance torque, or a assistance/resistance torque.

Abstract: The present invention relates a system and method to allow users to train different joints of a limb in different planes. The rotation of the system can be driven by a motor to assist or resist the motion for training purpose. By the present invention, the user can use the device to switch training between the vertical and horizontal planes, without changing the device and any module. The system is also adjustable to meet different users' body sizes.

Abstract: An electrical stimulation device for a body part of a person comprises an orthosis with sensor and electrodes and a controller. The controller receives a sensor signal, compares the sensor signal to a threshold value and generates an electrical output from the electrodes if the sensor signal exceeds the threshold value. The controller comprises a calibration module for determining an initial resting position of the body part.

Abstract: An electrical stimulation device for a body part of a person comprises an orthotic with sensor and electrodes and a controller. The controller receives a sensor signal, compares the sensor signal to a threshold value and generates an electrical output from the electrodes if the sensor signal exceeds the threshold value. A docking station facilitates connection of the electrodes and sensors to a computer. The docking station including a first processor for measuring values of the sensor signal and the electrical outputs and a second processor for generating electrical outputs on the electrodes.

Abstract: An electrical stimulation device has a sensor for detecting a movement event of a body part and an electrode for making electrical contact with an area of the body part. A controller coupled to the sensor and electrode receives a sensor signal indicating the movement event, and outputs to the electrode an output comprising a rise signal, a stimulation signal and a fall signal. The computer records a duration of use and a number of movement events during the duration of use in a log file. A handheld remote control allows stimulation data to be sent to the device and stored in a stimulation file.
