System for rehabilitation of a limb of a patient

1 . 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.

2 . The system ( 100 ) as claimed in claim 1 , wherein the first pre-specified time frame expires, when the effort signal reaches a pre-specified threshold.

3 . The system ( 100 ) as claimed in claim 1 , wherein the effort signal is communicated to the controller ( 110 ) over full second pre-specified time frame in the form of an audio/visual feedback.

4 . The system ( 100 ) as claimed in claim 3 , wherein the system ( 100 ) comprises a user interface ( 116 ), coupled with the controller ( 110 ) to:

assist the patient to set a predetermined set of parameters for enabling the movement of the limb; and

provide the audio-visual feedback over the second pre-specified time frame.

5 . The system ( 100 ) as claimed in claim 4 , wherein the user interface ( 116 ) is integrated with the controller.

6 . The system ( 100 ) as claimed in claim 1 , wherein the activity monitor ( 102 ) is a biosensor.

7 . The system ( 100 ) as claimed in claim 1 , wherein the activity monitor ( 102 ) is a muscle activity monitor.

8 . The system ( 100 ) as claimed in claim 1 , wherein the brain stimulation unit ( 106 ) is a magnetic unit.

9 . The system ( 100 ) as claimed in claim 1 , wherein the brain stimulation unit ( 106 ) is an electric unit.
