SYSTEMS AND METHODS FOR COORDINATING MUSCULOSKELETAL AND CARDIOVASCULAR OR CEREBROVASCULAR HEMODYNAMICS
First Claim
1. A method for favorably coordinating a timing relationship between an MSKC of a rhythmic musculoskeletal activity of a user and a CC of the user, the method comprising:
- recurrently providing a movement guidance from a prompt device to the user for guiding performance of the rhythmic musculoskeletal activity; and
repetitively;
detecting a signal, using a sensor, that correlates to a cyclically-varying arterial blood volume in a tissue of the user;
determining an actual value of a measured characteristic of the signal that varies with the timing relationship between the MSKC and the CC of the user;
computing a trend of the actual value of the measured characteristic using a processor; and
adjusting the movement guidance based on the trend of the actual value so as to cause the actual value of the measured characteristic to approach a relative preferred value of the measured characteristic.

Abstract
Described herein are systems and methods for favorably coordinating a timing relationship between a musculoskeletal activity cycle and a cardiac cycle of a user. A method may include repetitively detecting a signal that correlates to a blood volume in the user; determining an actual value of the signal that varies with the timing relationship; computing a trend of the actual value of the signal; and adjusting the movement guidance based on the trend of the actual value. A system may include a prompt device configured to provide recurrently a movement guidance to the user for guiding performance of the rhythmic musculoskeletal activity; a sensor configured to provide a signal that correlates to a blood volume in the user; and a processor configured to determine an actual value of the signal that varies with the timing relationship and to adjust the movement guidance based on the trend of the actual value.

16. A system for favorably coordinating a timing relationship between an MSKC of a rhythmic musculoskeletal activity of a user with a CC of the user, the system comprising:
-
a prompt device, wherein the prompt device is configured to provide recurrently a movement guidance to the user for guiding performance of the rhythmic musculoskeletal activity; a sensor, wherein the sensor is configured to provide a signal that correlates to a cyclically-varying arterial blood volume in a tissue of the user; and a processor, coupled to the prompt device and the sensor, wherein the processor is configured to determine an actual value of a measured characteristic of the signal that varies with the timing relationship between the MSKC and the CC of the user, and further configured to adjust the movement guidance based on the trend of the actual value so as to cause the actual value of the measured characteristic to approach a relative preferred value of the measured characteristic. - View Dependent Claims (17, 18, 19)

20. A method for favorably coordinating a timing relationship between an MSKC of a rhythmic musculoskeletal activity of a user and a CC of the user, the method comprising:
repetitively; detecting a signal responsive to cyclically-varying arterial blood volume in a tissue of the user, using a sensor; determining a first measured characteristic of the signal that repeats at a HR of the user and determining the HR of the user from the first characteristic; recurrently providing a guidance prompt from a prompt device to the user as a timing indication for performance of a rhythmic MSK activity, wherein the HR is an integer multiple of the rate of the timing indication; determining a value of a second measured characteristic of the signal that varies with an actual MSKC to CC timing relationship of the user; and adjusting the guidance based on a trend of the value of the second measured characteristic towards a relative preferred value of the second measured characteristic corresponding to a target MSKC to CC timing relationship, thereby guiding the user towards substantially obtaining and maintaining the target MSKC to CC timing relationship.
