Abstract
The present disclosure generally relates to methods of using near infrared radiation, such as from a near infrared spectroscopy device, to monitor physical activity in a person. In one aspect, a method of measuring physiological parameters is provided. The method further includes determining a NIRS-derived measure of a tissue of a person using near infrared spectroscopy over a time period, associating the NIRS-derived measure to the time period to determine a function-related change, and associating the function-related change to a biomechanical function.

A method of measuring physiological parameters, comprising:
- determining a NIRS-derived measure of a tissue using near infrared (NIR) radiation over a time period, the time period including a resting period and an active period, comprising:
- emitting NIR radiation from an optical sensor of an NIRS device into a tissue of a subject during the resting period and the active period;
- detecting radiation emitted from the tissue of the subject during the resting period and the active period with the optical sensor;
- and
- calculating, based on the detected radiation, by one or more processors in communication with the NIRS device, the NIRS-derived measure for the resting period and the active period, wherein the NIRS-derived measure is oxygenation related data;
- associating the NIRS-derived measure as determined during the resting period to the NIRS-derived measure as determined during the active period to determine a function-related change;
- associating the function-related change to a biomechanical function, wherein the biomechanical function is incorporated into a time frame activity score;
- associating a change in intensity of the NIRS-derived measure over the time period to determine an occurrence and an intensity of the biomechanical function;
- and
- displaying the time frame activity score, the occurrence of the biomechanical function, or the intensity of the biomechanical function to a user.

- associating the function-related change to a biomechanical function, wherein the biomechanical function is incorporated into a time frame activity score;
- and
- associating a change in intensity of the NIRS-derived measure over the time period to determine an occurrence and an intensity of the biomechanical function;
- and
- displaying the time frame activity score, the occurrence of the biomechanical function, or the intensity of the biomechanical function to a user.
