Portable and wearable hand-grasp neuro-orthosis

A hand-grasp neuro-orthosis configured for use in conjunction with a subject with hemiplegia, quadriplegia, or tetraplegia, the hand-grasp neuro-orthosis comprising:

• a wearable sleeve with electrodes;
• electromyography (EMG) amplifiers integrated with the wearable sleeve and configured to record and digitize EMG signals acquired via the electrodes, the EMG amplifiers integrated with the wearable sleeve including switches that automatically disconnect and reconnect the EMG amplifiers;
• electronics for operating the wearable sleeve to perform functional electrical stimulation (FES) and EMG, the electronics configured to generate a sync output to automatically operate the switches of the EMG amplifiers to disconnect the EMG amplifiers from the electrodes before FES is applied and to reconnect the EMG amplifiers with the electrodes after the FES is applied;
• and
• a controller configured for controlling the electronics to read EMG via the EMG amplifiers integrated with the sleeve, decode the read EMG to determine an intent of the user, and operate the electronics to apply FES via the sleeve to implement the intent of the user.
