Abstract
A set of therapy parameter values is selected based on a patient state, where the patient state comprises a speech state or a mixed patient state including the speech state and at least one of a movement state or a sleep state. In this way, therapy delivery is tailored to the patient state, which may include one or more patient symptoms specific to the patient state. In some examples, a medical device determines whether the patient is in the speech state or a mixed patient state including the speech state based on a signal generated by a voice activity sensor. The voice activity sensor detects the use of the patient's voice, and may include a microphone, a vibration detector or an accelerometer.
Claims28
A method comprising:
- receiving input from a voice activity sensor;
- determining a patient state based on the input from the voice activity sensor, wherein the patient state comprises at least one of a speech state or the speech state and at least one of a movement state or a sleep state;
- and
- selecting a set of therapy parameter values from a plurality of stored sets of therapy parameters based on the patient state, wherein the plurality of stored sets of therapy parameters comprises sets of therapy parameters associated with a respective one of the speech state and the at least one of the movement or sleep states.
A system comprising:
- a sensor that generates a signal indicative of voice activity of a patient;
- a memory that stores a plurality of sets of therapy parameter values, and associates each set of therapy parameter values with a patient state, the patient state comprising at least one of a speech state, or the speech state and at least one of a movement state or a sleep state;
- and
- a processor that determines a patient state based on the signal generated by the sensor and selects a set of therapy parameter values from the memory based on the determined patient state.
A computer-readable medium comprising instructions that cause a programmable processor to:
- receive input from a voice activity sensor;
- determine a patient state based on the input from the voice activity sensor, wherein the patient state comprises at least one of a speech state or the speech state and at least one of a movement state or a sleep state;
- and
- select a set of therapy parameter values from a plurality of stored sets of therapy parameters based on the patient state, wherein the plurality of stored sets of therapy parameters comprises sets of therapy parameters associated with a respective one of the speech state and the at least one of the movement or sleep states.
A system comprising:
- means for generating a signal indicative of voice activity of a patient;
- means for determining a patient state based on the signal indicative of voice activity of the patient, wherein the patient state comprises at least one of a speech state or the speech state and at least one of a movement state or a sleep state;
- and
- means for selecting a set of therapy parameter values from a plurality of stored sets of therapy parameters based on the patient state, wherein the plurality of stored sets of therapy parameters comprises sets of therapy parameters associated with a respective one of the speech state and the at least one of the movement or sleep states.
