Functional electrical stimulation to re-learn how to execute impaired functions, instead of making the consumer dependent on neuroprostheses for the rest of her/his life. Neurons are electrically active cells. In neurons, information is coded and transmitted as a series of electrical impulses called action potentials, which represent a brief change in cell electric potential of approximately 80–90 mV. Nerve signals are frequency modulated; i.e. the number of action potentials that occur in a unit of time is proportional to the intensity of the transmitted signal. Typical action potential frequency is between 4 and 12 Hz. An electrical stimulation can artificially elicit this action
The Boston process approach of the main modifications are listed below: The Boston process approach is known to be a flexible battery approach when assessing brain function of a person, meaning that there can be many different standardized tests that can be administered to the individual depending on their existing deficiencies. Data interpretation from this approach does not necessarily look at the final score on the tests, rather it focuses on what kind of errors were made by the individual during the assessment. Results from the Boston process approach allow the clinician to make inferences about what brain areas may not be working properly
