A posture correcting device using vibration or emitted electrical pulses in a pre-determined time sequence that may be adjusted in timing, intensity or strength, and a device for securing said posture correcting device to a body of a wearer.

A wearable device for detection of a posture deviation of a body of a user, and to provide proper alignment thereon, comprises a resting pad adapted to cover a back region of the body of the user, wherein the resting pad includes an internal surface oriented towards the back region, and an external surface oriented away from the back region, a supporting unit adapted to be attached with the resting pad, at the external surface, wherein the supporting unit further includes a back stretcher adapted to be deformed through flexure, and a flexing mechanism adapted to cause the flexure of the back stretcher and a sensor unit configured to determine deviation in the posture of the body of the user. Further, the resting pad is made of a flexible material to accommodate the flexure of the back stretcher.

A method includes receiving monitoring data from at least one sensing device coupled to a subject and analyzing the monitoring data to identify one or more physiologic parameters of the subject. The method also includes providing signaling to at least one stimulating device in response to the identified physiologic parameters, the signaling comprising instructions to apply a stimulus to the subject. The method further includes receiving additional monitoring data from the at least one sensing device, analyzing the additional monitoring data to identify one or more changes in the one or more physiologic parameters of the subject after application of the stimulus to the subject, and providing additional signaling to the at least one stimulating device, the additional signaling comprising instructions to modify the stimulus applied to the subject based on the identified changes in the one or more physiologic parameters.

Devices, systems, and techniques for calibrating posture state definitions are described. In one example, a system includes a memory configured to store a plurality of posture state definitions defining a plurality of posture states. The system may also include processing circuitry configured to receive a request to update the plurality of posture state definitions, responsive to receiving the request, and obtain sensor data for one posture state of the plurality of posture states, wherein the sensor data generated while a patient is in the one posture state. The processing circuitry may also determine a difference between the sensor data and a posture state definition of the posture state definitions corresponding to the one posture state, update, based on the difference, the plurality of posture state definitions, and store the updated plurality of posture state definitions in the memory.
