Fitness monitoring systems and methods based on continuous collection of physiological data

A method of assessing back pain in a user, comprising:

• providing a wearable configured to be worn on or around a torso of the user, the wearable comprising one or more sensors attached to a back portion of the wearable;
• controlling the one or more sensors to measure one or more movement characteristics of a back of the user while the user is wearing the wearable;
• issuing one or more prompts to a computing device associated with the user, the prompts requesting input indicative of a psychological perception of a pain level of the user;
• receiving, at the computing device, one or more indications of user input in response to the prompts, each indication providing data indicative of the psychological perception of the pain level of the user;
• analyzing, by one or more processors, the measured movement characteristics and the data indicative of the psychological perception of the pain level to produce an assessment of back pain for the user;
• and
• outputting, to an output component, the assessment of the back pain for the user.

A system comprising:

• a garment to be worn on or around a torso of a user;
• a flexible printed circuit board including a plurality of sensors attached to a back portion the garment;
• and
• one or more processors configured to:
• control each of the plurality of sensors to measure one or more movement characteristics of a back of the user wearing the wearable;
• analyze the one or more movement characteristics of the back of the user to produce an assessment of back pain for the user;
• and
• output, to an output component, the assessment of the back pain for the user.
