Abstract
The invention relates to a system (100), for rehabilitation of a limb of a patient, that comprises a controller (110) communicatively coupled to an activity monitor (102) and operatively coupled to a robotic exoskeleton unit (104) and a brain stimulation unit (106). The activity monitor (102) detects an activity of the limb of the patient by a voluntary attempt of the patient in a first time frame and communicates the voluntary attempt to the controller over a second time frame. The robotic exoskeleton unit completes the movement of the limb, and the brain stimulation unit externally stimulates a local motor region of a brain of the patient based on the effort signal reaching a pre-specified threshold to complete a sensorimotor loop.
Claims9
A system (100) for rehabilitation of a limb of a patient, the system (100) comprising:
- an activity monitor (102);
- a robotic exoskeleton unit (104) to assist a movement of the limb of the patient;
- a brain stimulation unit (106);
- a controller (110) communicatively coupled to the activity monitor (102) and operatively coupled to the robotic exoskeleton unit (104) and the brain stimulation unit (106), and
- a control circuitry,
- wherein the activity monitor (102) is to:
- in a first pre-specified time frame, detects an activity of the limb of the patient by a voluntary attempt of the patient and generate an effort signal based on the detection;
- and
- upon expiry of the first pre-specified time frame, communicate the effort signal to the controller (110) over a second pre-specified time frame,
- wherein the controller (110) is to, upon expiry of the first pre-specified time frame, simultaneously activate the robotic exoskeleton unit (104) and the brain stimulation unit (106) over the initiation of second pre-specified time frame,
- wherein the robotic exoskeleton unit (104) is to complete the movement of the limb of the patient, according to pre-defined set of parameters by the user, over the second pre-specified time frame,
- wherein the brain stimulation unit (106) is to externally stimulate a local motor region of a brain of the patient to complete a sensorimotor loop over the second pre-specified time frame, wherein the local motor region of the brain of the patient controls the movement of the limb of the patient,
- wherein the control circuitry is to trigger the brain stimulation unit (106) to synchronize a neural activity of the brain generated by the voluntarily attempt of the patient with a brain stimulation, within milliseconds of detecting by the activity monitor (102), over initiation of the second pre-specified time frame, the neural activity being generated by the voluntary attempt of the patient, and
- wherein the activity monitor (102) comprises a feedback engine (202) coupled to the controller (110), wherein the controller (110) is to;
- receive an input from the activity monitor (102) on the basis of which the effort signal is given as a performance of the patient based on the signal effort;
- based on the input, determine if a cycle period including the first prespecified time frame and the second prespecified time frame can be modified;
- and
- based on the determining, automatically modify the cycle period according to the performance of the patient.
