Rehabilitation system for neurological disorders

摘要

A rehabilitation system for neurological disorders, especially for the rehabilitation of patients being in a vegetative state or minimal conscious state, comprises at least two sensors adapted to measure two different physiological values of the patient and a stimulation generator. Initially predefined target signals determined and based on parameters relating to the injury are generated and, during a rehabilitation session, compared with the measurement signals to drive the stimulation generators delivering sensory stimulation to the patient as feedback. The controlling processor is adapted to change the predefined target signals during a rehabilitation session based on the development or changes of the measurement signals of the different physiological values, to enable a faster and better improvement of the alertness of the patient.

1. A rehabilitation system for neurological disorders comprising:
at least two sensors measuring different physiological values of a patient; a memory storing parameters unique to the patient and an injury; at least two stimulation generators; and a computer processor, wherein the memory is connected to the computer processor such that said parameters are delivered from the memory to the computer processor, and the at least two sensors are connected to the computer processor such that measurement signals are delivered from the at least two sensors to the computer processor, further wherein the computer processor: initially generates predefined target signals determined and based on the parameters; during a rehabilitation session, compares the measurement signals with the target signals and drives the at least two stimulation generators delivering sensory stimulation to the patient as feedback; and the computer processor changes the predefined target signals during the rehabilitation session based on development or changes of the measurement signals of the different physiological values, further wherein the target signals are arranged as a target vector signal, the at least two measurement signals are arranged as a measured vector signal, and the measured vector signal is compared with the target vector signal to obtain a comparison result which controls and drives the at least two stimulation generators delivering different sensory stimulation to the patient as feedback, and a time interval and an improvement threshold vector are defined for a rehabilitation session, wherein at an end of such a time interval, a change of initial measurement signals to current measurement signals and/or a difference of current measurement signals with existing target signals is compared to the improvement threshold vector and, if an improvement does not reach the improvement threshold vector, the at least two stimulation generators delivering sensory stimulation to the patient as feedback are set to follow new predefined target signals.
