A wearable electrical stimulation system for improving a motor function of a patient after the patient has a stroke. The system is deployed by positioning one stimulation unit on the head patient in electrical communication with a first portion of the patient's brain, positioning a second stimulation unit on a region of the patient comprising muscles requiring motor function improvement, and using a controller to activate the first stimulation unit and second stimulation unit. Upon activation, the first stimulation unit applies electrical stimulation to the first portion of the patient's brain and upon activation the second stimulation unit applies electrical stimulation to the first region of the patient. A system comprising a plurality of sensors for monitoring and improving the functions such as posture, movement, gait of a limb or a body portion is also disclosed.
