A trunk exoskeleton is provided including a flexible corset configured to wrap around a user's torso in the lumbar spine region. The flexible corset includes a plurality of vertical pockets formed around its perimeter. A plurality of flexor columns are included, each of which positioned in one of the plurality of vertical pockets. The flexor columns generate a flexor righting torque when bent from a vertical orientation. The multiple flexor righting torques from each of the plurality of flexor columns combine to generate a combined flexor righting torque. The combined flexor righting torque comprises a portion of a user trunk torque when the user's torso is angled from vertical.

Electrical non-invasive brain stimulation (NIBS) delivers weak electrical currents to the brain via electrodes that are affixed to the scalp. NIBS can excite or inhibit the brain in areas that are impacted by that electrical current during and for a short time following stimulation. Electrical NIBS can be used to change brain structure in terms of increasing white matter integrity as measured by diffusion tensor imaging. Together the electrical NIBS can induce changes in brain structure and function. The present methods and devices are adaptable to and configurable for facilitating the enhancement of brain performance, and the treatment of neurological diseases and tissues. The present methods and devices are advantageously designed to utilize modern electrodes deployed with, inter alia, various spatial arrangements, polarities, and current strengths to target brain areas or networks to thereby enhance performance or deliver therapeutic interventions.

Systems, methods, and devices for treating chronic pains effectively are disclosed. The system is based on the use of randomly generated non-pulsed waveform between a frequency of 5 Hz to 2 KHz. The waveforms generated have characteristics which are pre-defined or based on the input and feedback provided by the patient and/or by the clinician, at the same time conforming to certain safety rules and precautions ensuring patient safety. This disclosure also describes a novel approach of implementing a secure memory stick which can be used to exchange data securely between one device and another device where device could be the device mentioned earlier, an off-line server, or a PC.

Stimulation of nervous system components by electrodes can be used in many applications, including in the operation of brain-machine interfaces, bidirectional neural interfaces, and neuroprosthetics. The optimal operation of such systems requires a means of accurately measuring neural responses to such stimulations. However, currently the measurement of neural responses is difficult due to heavy stimulation artifacts arising from stimulatory pulses. The invention encompasses novel methods of estimating stimulation artifacts in measurements attained by recording electrodes and the effective removal of these artifacts. This provides improved neural recording systems and enables the deployment of closed-loop neural stimulation systems.

Methods of performing diagnostic tests on electroencephalography (EEG) recording devices comprising at least one stimulator coupled with a plurality of EEG electrode recording channels and corresponding recording channel connectors are performed by a test fixture comprising a plurality of resistors coupled with one or more of the EEG electrode recording channels and corresponding recording channel connectors. The methods include performing an impedance test for determining if each EEG recording channel of the EEG recording device has a predefined impedance, performing a channel uniqueness test for each EEG recording channel, performing a test for verifying the state of a switch of the stimulator of the EEG recording device, and performing a test for verifying connector IDs of the recording channel connectors connecting the EEG electrodes to respective EEG recording channels.

A skin treatment device has one or more electrodes adapted for application of a current to a skin surface of a subject, a voltage or current supply configured to generate the current, and a controller configured to modulate the power output to the skin surface. The controller includes a monitor circuit configured to generate feedback responsive to a change in the power output to the skin surface, based at least in part on the current, and a control circuit configured to modulate the current, based on the feedback.
