Interventive-diagnostic device
Apparatus for improving health of a user is provided, including a first sensor, adapted to measure a first physiological variable, which is indicative of a voluntary action of the user. A second sensor is adapted to measure a second physiological variable, which is substantially governed by an autonomic nervous system of the user. Circuitry is adapted to receive respective first and second sensor signals from the first and second sensors, and, responsive thereto, to generate an output signal which directs the user to modify a parameter of the voluntary action.
1. A method for generating music, comprising:
receiving a rhythm signal corresponding to a rhythm of a cyclic physiological activity of a user, the physiological activity having first and second activity phases thereof;
analyzing the rhythm signal to determine first and second durations thereof, respectively corresponding to the first and second activity phases;
determining first and second new durations responsive to desired changes of the first and second durations of the rhythm signal;
generating responsive to the new durations a music signal for presentation to the user, the music signal having first and second music phases thereof respectively corresponding to the first and second activity phases, a duration of each of the music phases expressible as being approximately equal to an integer multiple of a base duration, the integer multiple being less than or equal to four; and
directing the user to modify durations of the first and second activity phases responsive to the respective durations of the first and second music phases.
2. A method according to claim 1 , wherein generating the music signal comprises setting the duration of one of the music phases to be approximately equal to an integer multiple of the other one of the music phases.
3. A method according to claim 1 , wherein directing the user to modify the durations comprises directing the user to attempt to perform the first and second activity phases of the physiological activity such that the respective durations thereof are substantially equal to the durations of the first and second music phases.
4. A method according to claim 1 , wherein receiving the rhythm signal comprises receiving a motion signal corresponding to an activity of the user selected from the list consisting of: walking, jogging, and running.
5. A method according to claim 1 , wherein receiving the rhythm signal comprises receiving a respiration signal corresponding to respiration of the user.
6. A method according to claim 5 , wherein receiving the breathing signal comprises receiving an indication of a timing characteristic of inspiratory and expiratory phases of the respiration.
7. A method according to claim 1 , wherein determining the new durations comprises determining the new durations responsive to a vasomotor frequency of the user.

9. Apparatus for generating music, comprising:
a sensor, adapted to receive a rhythm signal corresponding to a rhythm of a cyclic physiological activity of a user, the physiological activity having first and second activity phases thereof;
a processor, adapted to analyze the rhythm signal to determine a frequency thereof and to determine a new frequency responsive to a desired change of the frequency of the rhythm signal; and
circuitry, adapted to:
generate at the new frequency a music signal for presentation to the user, the music signal having first and second music phases thereof respectively corresponding to the first and second activity phases, a duration of each of the music phases expressible as being approximately equal to an integer multiple of a base duration, the integer multiple being less than or equal to four,
so as to direct the user to modify durations of the first and second activity phases responsive to the respective durations of the first and second music phases.
