Abstract:
A method for delivering electrical therapy to a recipient, comprising:coupling an electrode to the recipient; applying electrical pulses to the electrode; varying a frequency of the electrical pulses over a first range of frequencies for a first period of time greater than 6 seconds during a therapy session; varying the frequency of the electrical pulses over a second range of frequencies for a second period of time approximately the same as the first period of time during the therapy session; wherein varying the frequency over the first range of frequencies includes gradually changing the frequency from about 4 Hz to about 10 Hz over an approximately 7 second interval, and wherein the method further comprises: maintaining the frequency at about 4 Hz for about 10 seconds before changing the frequency from about 4 Hz to about 10 Hz; maintaining the frequency at about 10 Hz for about 10 seconds after changing the frequency from about 4 Hz to about 10 Hz; and changing the frequency from about 10 Hz to about 4 Hz over an approximately 6 second interval.
